Change Notification Layout

Question

I decompiled my system music app (from Sony Ericsson for Android GB 2.3.7) because I want to change the notification layout. I found the method which creates the notification with this code:

private void sendStatusBarNotification(Track paramTrack) {     if (paramTrack != null)     {         NotificationManager localNotificationManager = (NotificationManager)this.mContext.getSystemService("notification");         String str = paramTrack.getArtist();          if ((str == null) || (str.equals(this.mContext.getString(2131361954))))             str = this.mContext.getString(2131361798);          Notification localNotification = new Notification(2130837696, paramTrack.getTitle() + " - " + str, System.currentTimeMillis());         localNotification.flags = (0x2 | localNotification.flags);         localNotification.flags = (0x20 | localNotification.flags);          PendingIntent localPendingIntent = PendingIntent.getActivity(this.mContext, 0, new Intent(this.mContext, MusicActivity.class), 268435456);         localNotification.setLatestEventInfo(this.mContext, paramTrack.getTitle(), str, localPendingIntent);         localNotificationManager.notify(0, localNotification);     } } 

My question now is: How can I change the notification layout? I want to build a layout which looks like the original android notification layout but with an extra image on the right of the notification. How can I do this?

Answer 1

First create an xml for your notification.

custom_notification.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/layout"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:padding="10dp" >     <ImageView android:id="@+id/image"         android:layout_width="wrap_content"         android:layout_height="fill_parent"         android:layout_alignParentLeft="true"         android:layout_marginRight="10dp" />     <TextView android:id="@+id/title"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_toRightOf="@id/image"         style="Custom Notification Title" />     <TextView android:id="@+id/text"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_toRightOf="@id/image"         android:layout_below="@id/title"         style="Custom Notification Text" /> </RelativeLayout> 

Now the java code:

public class MainActivity extends Activity {      @SuppressWarnings("deprecation")     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);          int icon = R.drawable.ic_launcher;         long when = System.currentTimeMillis();         Notification notification = new Notification(icon, "Custom Notification", when);          NotificationManager mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);          RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);         contentView.setImageViewResource(R.id.image, R.drawable.ic_launcher);         contentView.setTextViewText(R.id.title, "Custom notification");         contentView.setTextViewText(R.id.text, "This is a custom layout");         notification.contentView = contentView;          Intent notificationIntent = new Intent(this, MainActivity.class);         PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);         notification.contentIntent = contentIntent;          notification.flags |= Notification.FLAG_NO_CLEAR; //Do not clear the notification         notification.defaults |= Notification.DEFAULT_LIGHTS; // LED         notification.defaults |= Notification.DEFAULT_VIBRATE; //Vibration         notification.defaults |= Notification.DEFAULT_SOUND; // Sound          mNotificationManager.notify(1, notification);     }      @Override     public boolean onCreateOptionsMenu(Menu menu) {         getMenuInflater().inflate(R.menu.activity_main, menu);         return true;     } } 

Hope this thing works for you.

Edit April 26 2016 You can use NotificationCompat.Builder for creating Notification instance as below:

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)             .setSmallIcon(icon)             .setContent(contentView)             .setContentTitle("Custom Notification")             .setWhen(when); ... mNotificationManager.notify(1, notificationBuilder.build());
