<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:padding="4dp" tools:context=".MainActivity"> <EditText android:id="@+id/etTo" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="5dp" android:hint="Receiver's Email Address!" android:inputType="textEmailAddress" android:singleLine="true" /> <EditText android:id="@+id/etSubject" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margin="5dp" android:hint="Enter Subject" android:singleLine="true" /> <EditText android:id="@+id/etMessage" android:layout_width="match_parent" android:layout_height="200dp" android:layout_margin="5dp" android:gravity="top|start" android:hint="Compose Email" android:inputType="textMultiLine" /> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <Button android:id="@+id/btSend" android:layout_width="80dp" android:layout_height="50dp" android:layout_margin="5dp" android:text="Send" /> <Button android:id="@+id/btAttachment" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentEnd="true" android:text="attachment" /> </RelativeLayout> <TextView android:id="@+id/tvAttachment" android:layout_width="match_parent" android:layout_height="wrap_content" android:drawableStart="@drawable/ic_attach" android:visibility="gone" /> </LinearLayout>
Step 3 − Add the following code to src/MainActivity.java
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
EditText etEmail;
EditText etSubject;
EditText etMessage;
Button Send;
Button attachment;
TextView tvAttachment;
String email;
String subject;
String message;
Uri URI = null;
private static final int PICK_FROM_GALLERY = 101;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etEmail = findViewById(R.id.etTo);
etSubject = findViewById(R.id.etSubject);
etMessage = findViewById(R.id.etMessage);
attachment = findViewById(R.id.btAttachment);
tvAttachment = findViewById(R.id.tvAttachment);
Send = findViewById(R.id.btSend);
Send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
sendEmail();
}
});
//attachment button listener
attachment.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
openFolder();
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_FROM_GALLERY && resultCode == RESULT_OK) {
URI = data.getData();
tvAttachment.setText(URI.getLastPathSegment());
tvAttachment.setVisibility(View.VISIBLE);
}
}
public void sendEmail() {
try {
email = etEmail.getText().toString();
subject = etSubject.getText().toString();
message = etMessage.getText().toString();
final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("plain/text");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{email});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
if (URI != null) {
emailIntent.putExtra(Intent.EXTRA_STREAM, URI);
}
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);
this.startActivity(Intent.createChooser(emailIntent, "Sending email..."));
} catch (Throwable t) {
Toast.makeText(this, "Request failed try again: "+ t.toString(), Toast.LENGTH_LONG).show();
}
}
public void openFolder() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.putExtra("return-data", true);
startActivityForResult(Intent.createChooser(intent, "Complete action using"), PICK_FROM_GALLERY);
}
}Step 4 − Add the following code to androidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.sample"> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" 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>
