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" >

</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;

import android.database.Cursor;

import android.inputmethodservice.Keyboard.Key;

import android.net.Uri;

import android.os.Bundle;

import android.provider.ContactsContract.CommonDataKinds.Phone;

import android.telephony.SmsManager;

import android.view.KeyEvent;

import android.view.View;

import android.view.View.OnClickListener;

import android.view.View.OnKeyListener;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;

public class Create_msg extends Activity {

String[] numberlist = new String[20];

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"?>

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

package="c.him.smsapll"

android:versionCode="1"

android:versionName="1.0" >

<uses-sdk

android:minSdkVersion="8"

android:targetSdkVersion="17" />

<uses-permission android:name="android.permission.READ_SMS"/>

<uses-permission android:name="android.permission.WRITE_SMS"/>

<application

android:allowBackup="true"

android:icon="@drawable/sms"

android:label="@string/app_name"

android:theme="@style/AppTheme" >

<activity

android:name="c.him.smsapll.MainActivity"

android:label="@string/app_name" >

<intent-filter>

</intent-filter>

</activity>

<activity android:name="Create_msg"

android:label="@string/c_msg">

</activity>

<activity android:name="Inbox"

android:label="@string/Inbox_msg">

</activity>

<activity android:name="Sent_item"

android:label="@string/Send_item_msg">

</activity>

<activity android:name="Forward_msg"

android:label="@string/Frd_msg">

</activity>

<activity android:name="ViewMesg"

android:label="@string/View_msg">

</activity>

</application>

</manifest>

And at last see the output as in the following:
