Step 4

Here, NewProject is open and you will go to design page (activity_main.xml) and you will build the design, it should follow the drag and drop method, it is the option (editText,Button).

Here,you will see the design page(Graphical user Interface).

Now,you will see the activity_main.xml code

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="xyz.rvconstructions.www.sendemailapp.MainActivity">
<EditText android:layout_width="wrap_content" android:layout_height="wrap_content" android:inputType="textEmailAddress" android:ems="10" android:id="@+id/editText" android:layout_alignParentTop="true" android:layout_alignParentRight="true" android:layout_alignParentEnd="true" />
<EditText android:layout_width="wrap_content" android:layout_height="wrap_content" android:inputType="textEmailAddress" android:ems="10" android:id="@+id/editText2" android:layout_below="@+id/editText" android:layout_alignRight="@+id/editText" android:layout_alignEnd="@+id/editText" />
<EditText android:layout_width="wrap_content" android:layout_height="wrap_content" android:inputType="textEmailAddress" android:ems="10" android:id="@+id/editText3" android:layout_below="@+id/editText2" android:layout_alignRight="@+id/editText2" android:layout_alignEnd="@+id/editText2" />
<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="SEND MAIL" android:id="@+id/sendbttn" android:layout_centerVertical="true" android:layout_alignLeft="@+id/editText3" android:layout_alignStart="@+id/editText3" />
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Recipient" android:id="@+id/textView" android:layout_alignBottom="@+id/editText" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" />
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="subject" android:id="@+id/textView2" android:layout_alignBottom="@+id/editText2" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" />
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Message Body" android:id="@+id/textView3" android:layout_alignBottom="@+id/editText3" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" /> </RelativeLayout>

Step 5

Now ,you will build on AndroidManifest.xml code.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="xyz.rvconstructions.www.sendemailapp">
<application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" /> </intent-filter>
</activity>
</application>
</manifest>

Step 6

Now, you will go to MainActivity.java page and you will build the java code.

First of all you will declare the Header file.

application name

package xyz.rvconstructions.www.sendemailapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.net.Uri;
import android.app.Activity;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

Now, you will declare and get the reference in the button and perform the OnClickListener.

Button startBtn = (Button) findViewById(R.id.sendbttn);
startBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
sendEmail();
}
});

Here, you will assign the method() of sendEmail().

application name

protected void sendEmail() {
Log.i("Send email", "");
String[] TO = {
"[email protected]"
};
String[] CC = {
"[email protected]"
};
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setData(Uri.parse("mailto:"));
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_EMAIL, TO);
emailIntent.putExtra(Intent.EXTRA_CC, CC);
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Your subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "Email message goes here");
try {
startActivity(Intent.createChooser(emailIntent, "Send mail..."));
finish();
Log.i("Finished sending email...", "");
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(MainActivity.this, "There is no email client installed.", Toast.LENGTH_SHORT).show();
}
}
// This is just a sample script. Paste your real code (javascript or HTML) here.
if ('this_is' == /an_example/) {
of_beautifier();
} else {
var a = b ? (c % d) : e[f];
}
