Simple SMS Application In Android

Introduction

Today I will explain how to work with a SMS application in Android. I made my own SMS apps. I will tell you how they work and how they are made. In this application I used a layout in witch I set many type layouts, all layouts and views are shown here.

In this application I have used many activity classes for easy coding. Since you know how to connect an activity to another, I also connect them in the manner shown here.

For this application you must have some clip art, you can save it in the draw able directory as shown below.

Step 1

Create a new project as shown below.

Step 2

Create a "create_msg_layout.xml" file as in the following coding.

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical" >

    <LinearLayout

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_alignParentLeft="true"

        android:layout_alignParentTop="true"

        android:layout_marginTop="1dp" >

        <TextView

            android:id="@+id/textView1"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:text="To " />

        <EditText

            android:id="@+id/edSendNo"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:ems="10"

            android:inputType="number" >

            <requestFocus />

        </EditText>

        <Button

            android:id="@+id/btContactFtech"

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            android:text="   "

            android:background="@drawable/contact" />

    </LinearLayout>

    <LinearLayout

        android:layout_width="match_parent"

        android:layout_height="360dp"

        android:layout_above="@+id/linearLayout1"

        android:layout_alignParentLeft="true"

        android:layout_alignParentTop="true"

        android:layout_marginTop="50dp" >

        <EditText

            android:id="@+id/edSendText"

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            android:ems="10"

            android:inputType="textMultiLine" />

    </LinearLayout>

    <LinearLayout

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_alignParentBottom="true"

        android:layout_centerHorizontal="true" >

        <Button

            android:id="@+id/btSend"

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            android:text="Send" />

    </LinearLayout>

</RelativeLayout>

Step 3

Create a "inbox.xml" file as in the following coding.

<?xml version="1.0" encoding="utf-8"?>

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        android:orientation="vertical"

        android:scrollbars="vertical">

        <TextView

            android:id="@+id/tvName"

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            android:layout_alignParentLeft="true"

            android:layout_alignParentTop="true"

            android:layout_marginLeft="17dp"

            android:text=""

            android:textAppearance="?android:attr/textAppearanceLarge" />

        <TextView

            android:id="@+id/tvDate"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_alignParentLeft="true"

            android:layout_below="@+id/tvName"

            android:text=""

            android:textAppearance="?android:attr/textAppearanceMedium" />

        <TextView

            android:id="@+id/tvTime"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_alignBaseline="@+id/tvDate"

            android:layout_alignBottom="@+id/tvDate"

            android:layout_marginLeft="34dp"

            android:layout_toRightOf="@+id/tvDate"

            android:text=""

            android:textAppearance="?android:attr/textAppearanceMedium" />

        <TextView

            android:id="@+id/tvSmallMsgView"

            android:layout_width="match_parent"

            android:layout_height="20dp"

            android:layout_alignParentLeft="true"

            android:layout_below="@+id/tvDate"

            android:text=""

            android:textAppearance="?android:attr/textAppearanceSmall" />

    </RelativeLayout>

Step 4

Create a "list_sms_layout.xml" file, you will see the coding of this file in my attachment.

Step 5

Create a "sent_item_list.xml" file, you will see the coding of this file in my  attachment.

Step 6

Create a "view_msg_layout.xml" file, you will see the coding of this file in my attachment.

Step 7

Now open the activity file "MainActivity.java" and update it with the following coding.

package c.him.smsapll;

import android.app.ListActivity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.widget.ArrayAdapter;

import android.widget.ListView;

import android.widget.Toast;

public class MainActivity extends ListActivity {

      @Override

      protected void onCreate(Bundle savedInstanceState) {

                  super.onCreate(savedInstanceState);            

            final String[] listItem = {"Create Message","Inbox","Send Item"};

/*          ArrayAdapter adapter = new ArrayAdapter(this,R.layout.list_sms_layout,R.id.textView1,listItem);

            setListAdapter(adapter);*/

            setListAdapter(new SmsArrayAdapter(this, listItem));

      }    

      @Override

      protected void onListItemClick(ListView l, View v, int position, long id) {

            // TODO Auto-generated method stub

            super.onListItemClick(l, v, position, id);

            switch (position) {

            case 0:

                        Intent i1 = new Intent(this,Create_msg.class);

                        startActivity(i1);

                  break;                 

            case 1:

                  Intent i2 = new Intent(this,Inbox.class);

                  startActivity(i2);                 

                  break;

            case 2:

                  Intent i3 = new Intent(this,Sent_item.class);

                  startActivity(i3);

                  break;

            default:

                  break;

            }

      }

}

Step 8

Create a new Java file "CreateMSG.java" as in the following coding.

package c.him.smsapll;

import java.util.ArrayList;

import android.annotation.SuppressLint;

import android.app.Activity;

import android.content.ContentValues;

import android.content.Intent;

      int numberlist_index=0;

      EditText edWrite_no,edWrite_text;

      Button bSend,bFetchContact;

      String myEnterNumber="";

      boolean isNumericEntered = false;

      static Boolean control=false;

      @Override

      protected void onCreate(Bundle savedInstanceState) {       

            super.onCreate(savedInstanceState);

            setContentView(R.layout.create_msg_layout);

            edWrite_no = (EditText)findViewById(R.id.edSendNo);

            edWrite_text=(EditText)findViewById(R.id.edSendText);

            edWrite_no.setOnKeyListener(new OnKeyListener() {

                  @Override

                  public boolean onKey(View v, int keyCode, KeyEvent event) {

                        if(control==false)

                        {

                              control=true;

                        }

                        else

                        {

                              control=false;

                              char pressedKey = (char)event.getUnicodeChar();

      if(pressedKey=='0'||pressedKey=='1'||pressedKey=='2'||pressedKey=='3'||pressedKey=='4'||pressedKey=='5'||pressedKey=='6'||pressedKey=='7'||pressedKey=='8'||pressedKey=='9')

                              {

                                    myEnterNumber =myEnterNumber + pressedKey;

                                    isNumericEntered=true;

                              }

                        }

                        return false;

                  }

            });

      }

      @Override

      protected void onResume() {

            // TODO Auto-generated method stub

            super.onResume();

      }

      protected void onStart() {

            super.onStart();

            bSend=(Button)findViewById(R.id.btSend);

            bFetchContact=(Button)findViewById(R.id.btContactFtech);

bFetchContact.setOnClickListener(new OnClickListener() {

                  @Override

                  public void onClick(View v) {

                        Uri uri = Uri.parse("content://contacts");

                         Intent pickContactIntent = new Intent(Intent.ACTION_PICK, uri);

                            pickContactIntent.setType(Phone.CONTENT_TYPE); // Show user only contacts w/ phone numbers

                            startActivityForResult(pickContactIntent, 1);

                  }

            });

 

            bSend.setOnClickListener(new OnClickListener() {

                 

                  @Override

                  public void onClick(View v) {

                        String s =  edWrite_no.getText().toString();

                        Check_addmyNumber();

                        try

                        {

                              if(numberlist_index <= 0)

                              {

                                    Toast.makeText(Create_msg.this, "Please, Either enter number or select number from contact.", Toast.LENGTH_SHORT).show();

                              }

                              else

                        while(numberlist_index > 0)

                        {

                        Toast.makeText(Create_msg.this, "Sender index number : " + numberlist_index, Toast.LENGTH_SHORT).show();

                        numberlist_index -=1;

                        String number = numberlist[numberlist_index];

                        /*sendLongSMS(number);

                        sendSMSRecordToSendItem(number);*/

                        Toast.makeText(Create_msg.this, "Sender number : " + number, Toast.LENGTH_SHORT).show();

                        numberlist[numberlist_index]=null;

                        // mistake // Toast.makeText(Create_msg.this, "Sender number (After operation): " + numberlist[numberlist_index], Toast.LENGTH_SHORT).show();               

                                          if(numberlist_index == 0){

                                               

                                                finish();

                                          }

 

                        }

                  }

                        catch(ArrayIndexOutOfBoundsException e)

                        {

                              Toast.makeText(Create_msg.this, "You can not send it more than 20 person.", Toast.LENGTH_SHORT).show();

                        }

                  }

            });

 

      }

      @Override

      protected void onActivityResult(int requestCode, int resultCode, Intent data) {

            super.onActivityResult(requestCode, resultCode, data);

             if (requestCode == 1) {

                    if (resultCode == RESULT_OK) {

                        Check_addmyNumber();

                        Uri contactUri = data.getData();

                         String[] projection = {Phone.NUMBER,Phone.DISPLAY_NAME,Phone.STATUS};

                        Cursor cursor = getContentResolver().query(contactUri, projection, null, null, null);

                        cursor.moveToFirst();

                        int column = cursor.getColumnIndex(Phone.NUMBER);

                        String number = cursor.getString(column);                  

                        //edWrite_no.setText(number);

                        numberlist[numberlist_index]=number;

                              numberlist_index +=1;

                        int column2 = cursor.getColumnIndex(Phone.DISPLAY_NAME);

                        String number2 = cursor.getString(column2);

                        edWrite_no.setText(edWrite_no.getText().toString()+ " " + number2);

                    }

                }

      }

      public void Check_addmyNumber(){

            if(isNumericEntered== true)

            {

            numberlist[numberlist_index]=myEnterNumber;

                  numberlist_index +=1;

                  myEnterNumber="";

                  isNumericEntered=false;

            }

      }

      public void sendLongSMS(String number) {

          String phoneNumber = number;//.getText().toString();

          String message = edWrite_text.getText().toString();

          SmsManager smsManager = SmsManager.getDefault();

          ArrayList<String> parts = smsManager.divideMessage(message);

          smsManager.sendMultipartTextMessage(phoneNumber, null, parts, null, null);

      }

      public void sendSMSRecordToSendItem(String number) {

            ContentValues values = new ContentValues();

            values.put("address", number);

            values.put("body", edWrite_text.getText().toString());

        getContentResolver().insert(Uri.parse("content://sms/sent"), values);

      }

}

Step 9

Create a file as "ForwordMSG.java", you will see the coding of this file in my attachment.

Step 10

Create a new file "Inbox.java" with the following coding.

package c.him.smsapll;

import java.text.DateFormat;

import java.util.Date;

import android.app.ListActivity;

import android.content.Intent;

import android.database.Cursor;

import android.net.Uri;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.ArrayAdapter;

import android.widget.ListView;

import android.widget.Toast;

public class Inbox extends ListActivity{

      String[] Inbox_name=new String[100],

                  Inbox_number=new String[100],

                  Inbox_date=new String[100],

                  Inbox_type=new String[100],

                  Inbox_msg=new String[100];

      int pos=0;

      @Override

      protected void onCreate(Bundle savedInstanceState) {

            // TODO Auto-generated method stub

            super.onCreate(savedInstanceState);

            Inbox_Read();

            setListAdapter(new InboxArrayAdapter(this,Inbox_name,Inbox_number,Inbox_date,Inbox_type,Inbox_msg));

      }

      @Override

      protected void onListItemClick(ListView l, View v, int position, long id) {

            // TODO Auto-generated method stub

            super.onListItemClick(l, v, position, id);

            Toast.makeText(Inbox.this, "Number : " + Inbox_number[position], Toast.LENGTH_SHORT).show();

            Intent intent = new Intent(this,ViewMesg.class);

            intent.putExtra("name", Inbox_name[position]);

            intent.putExtra("no",   Inbox_number[position]);

            intent.putExtra("date", Inbox_date[position]);

            intent.putExtra("time", Inbox_type[position]);

            intent.putExtra("msg",  Inbox_msg[position]);

            startActivity(intent);

      }

void Inbox_Read()

{

      Uri mSmsinboxQueryUri = Uri.parse("content://sms/inbox");

    Cursor cursor1 = getContentResolver().query(

            mSmsinboxQueryUri,

            new String[] { "_id", "thread_id", "address", "person", "date",

                    "body", "type" }, null, null, null);

startManagingCursor(cursor1);

    String[] columns = new String[] { "address", "person", "date", "body",

            "type" };

    if (cursor1.getCount() > 0) {

        String count = Integer.toString(cursor1.getCount());

        while (cursor1.moveToNext()) {

         

            String number = cursor1.getString(cursor1.getColumnIndex(columns[0]));

            String name = cursor1.getString(cursor1.getColumnIndex(columns[1]));

            String date = cursor1.getString(cursor1.getColumnIndex(columns[2]));

            String msg = cursor1.getString(cursor1.getColumnIndex(columns[3]));

            String type = cursor1.getString(cursor1.getColumnIndex(columns[4]));

            Inbox_name[pos]= name; 

            Inbox_number[pos] =number;

            if(date!=null)

            {

                  long l = Long.parseLong(date);

                  Date d = new Date(l);

                  Inbox_date[pos]=DateFormat.getDateInstance(DateFormat.LONG).format(d);

                  Inbox_type[pos]=DateFormat.getTimeInstance().format(d);

            }

            else

            {

                  Inbox_date[pos]=date;

                  Inbox_type[pos]=type;

            }

           

                  Inbox_msg[pos]=msg;

            pos +=1;

           

}

}

 }

}

Step 11

Create a new file "InboxArrayAdapter.java", you will see this coding in my attachment.

Step 12

Create new file "SentItem.java", you will see this in my attachment.

Step 13

Create a new file "SentItemArrayAdapter.java" with the following code.

package c.him.smsapll;

import java.util.Date;

import android.content.Context;

import android.util.Log;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ArrayAdapter;

import android.widget.ImageView;

import android.widget.TextView;

public class Sent_itemArrayAdapter extends ArrayAdapter {  

      private  Context context;

      private  String[] Send_item_name,Send_item_number,Send_item_date,Send_item_type,Send_item_msg;

      Sent_itemArrayAdapter(Context context,String[] Send_item_name,String[] Send_item_number,String[] Send_item_date,String[] Send_item_type,String[] Send_item_msg)

      {

      super(context,R.layout.sent_item, Send_item_number);

            this.context= context;

            this.Send_item_name=Send_item_name;

            this.Send_item_number=Send_item_number;

            this.Send_item_date=Send_item_date;

            this.Send_item_type=Send_item_type;

            this.Send_item_msg=Send_item_msg;

      }

            @Override

      public View getView(int position, View convertView, ViewGroup parent) {

                  LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

                        View rowView = inflater.inflate(R.layout.sent_item, parent, false);

                  //ImageView imageView = (ImageView) rowView.findViewById(R.id.imageView1);

                        TextView name = (TextView) rowView.findViewById(R.id.tvName);

                  TextView date = (TextView) rowView.findViewById(R.id.tvDate);

                  TextView msg = (TextView) rowView.findViewById(R.id.tvSmallMsgView);

                  TextView type = (TextView) rowView.findViewById(R.id.tvTime);

                        /*String s = Send_item_name[position];

                  if(s==null)

                  name.setText(Send_item_number[position]);

                  else

                        name.setText(Send_item_name[position]);*/

                  name.setText(Send_item_number[position]);

                  date.setText(Send_item_date[position]);

                  msg.setText(Send_item_msg[position]);

                  type.setText(Send_item_type[position]);

                  /*System.out.println(s);

                        if (s.equals("Create Message")) {

                        imageView.setImageResource(R.drawable.writemessage);

                  } else if (s.equals("Send_item")) {

                        imageView.setImageResource(R.drawable.Send_item);

                  } else if (s.equals("Send Item")) {

                        imageView.setImageResource(R.drawable.send);

                  } else {

                        imageView.setImageResource(R.drawable.ic_launcher);

                  }*/

       

                  return rowView;

      }

}

Step 14

Create a new file "SmsArray Adapter.java", you will see this coding in my attachment in the .rar file.

Step 15

 Now create a new file "Viewmsg.java" as in the following coding.

package c.him.smsapll;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.TextView;

public class ViewMesg extends Activity{

      TextView number,date,time,msg;

      Button frd;

      @Override

      protected void onCreate(Bundle savedInstanceState) {

            // TODO Auto-generated method stub

            super.onCreate(savedInstanceState);

            setContentView(R.layout.view_msg_layout);

            number=(TextView)findViewById(R.id.tvNumber);

            date=(TextView)findViewById(R.id.tvDate);

            time=(TextView)findViewById(R.id.tvTime);

            msg=(TextView)findViewById(R.id.tvMsg);

            frd=(Button)findViewById(R.id.btFrd);

      }

      @Override

      protected void onStart() {

            // TODO Auto-generated method stub

            super.onStart();

            Intent i = getIntent();

            number.setText(i.getStringExtra("no"));

            date.setText(i.getStringExtra("date"));

            time.setText(i.getStringExtra("time"));

            msg.setText(i.getStringExtra("msg"));

            //startActivity(i);

            frd.setOnClickListener(new OnClickListener() {

                        @Override

                  public void onClick(View v) {

                        Intent click = new Intent(ViewMesg.this,Forward_msg.class);

                        click.putExtra("message", msg.getText());

                        startActivity(click);

                       

                  }

            });

      }

 

}

Step 16

Now open the manifest file and update it using all the activities and permissions shown below.

<?xml version="1.0" encoding="utf-8"?>
