AndroidApps/ApplicationsMobile Development

This example demonstrate about How can I insert an EditText (for inserting text) on an Android notification

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<? 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"
   tools :context = ".MainActivity" >
   <Button
      android :onClick = "createNotification"
      android :layout_width = "match_parent"
      android :layout_height = "wrap_content"
      android :layout_centerInParent = "true"
      android :layout_margin = "16dp"
      android :text = "Create notification" />
</RelativeLayout>

Step 3 − Add the following code to res/layout/custom_notification_layout.xml.

<? xml version = "1.0" encoding = "utf-8" ?>
<RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android"
   android :id = "@+id/layout"
   android :layout_width = "fill_parent"
   android :layout_height = "96dp"
   android :padding = "10dp" >
   <ImageView
      android :id = "@+id/image"
      android :layout_width = "wrap_content"
      android :layout_height = "fill_parent"
      android :layout_alignParentStart = "true"
      android :layout_marginEnd = "10dp"
      android :contentDescription = "@string/app_name"
      android :src = "@mipmap/ic_launcher" />
   <TextView
      android :id = "@+id/title"
      android :layout_width = "wrap_content"
      android :layout_height = "wrap_content"
      android :layout_toEndOf = "@id/image"
      android :text = "Testing"
      android :textColor = "#000"
      android :textSize = "18sp" />
   <EditText
      android :layout_width = "match_parent"
      android :layout_height = "wrap_content"
      android :layout_below = "@+id/title"
      android :layout_marginTop = "8dp"
      android :layout_toEndOf = "@+id/image"
      android :hint = "Enter something..."
      android :inputType = "text"
      android :textSize = "14sp" />
</RelativeLayout>

Step 4 − Add the following code to src/MainActivity.

package app.tutorialspoint.com.notifyme ;
import android.app.NotificationChannel ;
import android.app.NotificationManager ;
import android.os.Bundle ;
import android.support.v4.app.NotificationCompat ;
import android.support.v7.app.AppCompatActivity ;
import android.view.View ;
import android.widget.RemoteViews ;
public class MainActivity extends AppCompatActivity {
   public static final String NOTIFICATION_CHANNEL_ID = "10001" ;
   private final static String default_notification_channel_id = "default" ;
   @Override
   protected void onCreate (Bundle savedInstanceState) {
      super .onCreate(savedInstanceState) ;
      setContentView(R.layout. activity_main ) ;
      onNewIntent(getIntent()) ;
   }
   public void createNotification (View view) {
      RemoteViews contentView = new RemoteViews(getPackageName() , R.layout. custom_notification_layout ) ;
      NotificationManager mNotificationManager = (NotificationManager) getSystemService( NOTIFICATION_SERVICE ) ;
      NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(MainActivity. this, default_notification_channel_id ) ;
      mBuilder.setContent(contentView) ;
      mBuilder.setSmallIcon(R.drawable. ic_launcher_foreground ) ;
      mBuilder.setAutoCancel( true ) ;
      if (android.os.Build.VERSION. SDK_INT >= android.os.Build.VERSION_CODES. O ) {
         int importance = NotificationManager. IMPORTANCE_HIGH ;
         NotificationChannel notificationChannel = new NotificationChannel( NOTIFICATION_CHANNEL_ID , "NOTIFICATION_CHANNEL_NAME" , importance) ;
         mBuilder.setChannelId( NOTIFICATION_CHANNEL_ID ) ;
         assert mNotificationManager != null;
         mNotificationManager.createNotificationChannel(notificationChannel) ;
      }
      assert mNotificationManager != null;
      mNotificationManager.notify(( int ) System. currentTimeMillis () , mBuilder.build()) ;
   }
}

Step 5 − 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.tutorialspoint.com.notifyme" >
   <uses-permission android :name = "android.permission.VIBRATE" />
   <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>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
