Answer 1

Add action button to notification

Intent snoozeIntent = new Intent(this, MyBroadcastReceiver.class);
snoozeIntent.setAction(ACTION_SNOOZE);
snoozeIntent.putExtra(EXTRA_NOTIFICATION_ID, 0);
PendingIntent snoozePendingIntent =
        PendingIntent.getBroadcast(this, 0, snoozeIntent, 0);

NotificationCompat.Builder mBuilder = new 
NotificationCompat.Builder(this, CHANNEL_ID)
        .setSmallIcon(R.drawable.notification_icon)
        .setContentTitle("My notification")
        .setContentText("Hello World!")
        .setPriority(NotificationCompat.PRIORITY_DEFAULT)
        .setContentIntent(pendingIntent)
        .addAction(R.drawable.ic_snooze, getString(R.string.snooze),
                snoozePendingIntent);

Answer 2

I will try to provide a solution that I have used and most of the music player also use the same technique to show player controls in notification bar.

I am running a service which is used to manage Media Player and all its controls. Activity User control interacts with Service by sending Intents to the service for example

 Intent i = new Intent(MainActivity.this, MyRadioService.class);
        i.setAction(Constants.Player.ACTION_PAUSE);

        startService(i);

TO receive intents and perform action in Service class I am using following code in onStartCommand method of Service

 @Override
public int onStartCommand(Intent intent, int flags, int startId) {


    if (intent.getAction().equals(Constants.Player.ACTION_PAUSE)) {
        if(mediaPlayer.isPlaying()) {
            pauseAudio();
        }
    }

Now to exact answer to your question to show notification with playing controls. You can call following methods to show notification with controls.

   //    showNotification
private void startAppInForeground() {
//  Start Service in Foreground

    // Using RemoteViews to bind custom layouts into Notification
    RemoteViews views = new RemoteViews(getPackageName(),
            R.layout.notification_status_bar);

// Define play control intent 
   Intent playIntent = new Intent(this, MyRadioService.class);
    playIntent.setAction(Constants.Player.ACTION_PLAY);

// Use the above play intent to set into PendingIntent
    PendingIntent pplayIntent = PendingIntent.getService(this, 0,
            playIntent, 0);

// binding play button from layout to pending play intent defined above 
views.setOnClickPendingIntent(R.id.status_bar_play, pplayIntent);
views.setImageViewResource(R.id.status_bar_play,
            R.drawable.status_bg);

Notification status = null;
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
        status = new Notification.Builder(this).build();
    }

  status.flags = Notification.FLAG_ONGOING_EVENT;
    status.icon = R.mipmap.ic_launcher;
    status.contentIntent = pendingIntent;
    startForeground(Constants.FOREGROUND_SERVICE, status);

} Hope this really helps you. And you will be able to achieve what you want. Have a Happy Coding :)

Answer 3

you can add button as below and can perform action on that button also i have done for me as below please check.

NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.ic_logo)
                        .setAutoCancel(true)
                        .setContentTitle(name)
                        .setContentText(body)
                        .setGroupSummary(true)
                        .addAction(android.R.drawable.ic_menu_directions, "Mark as read", morePendingIntent);

//morePendingIntent(do your stuff)

  PendingIntent morePendingIntent = PendingIntent.getBroadcast(
                        this,
                        REQUEST_CODE_MORE,
                        new Intent(this, NotificationReceiver.class)
                                .putExtra(KEY_INTENT_MORE, REQUEST_CODE_MORE)
                                .putExtra("bundle", object.toString()),
                        PendingIntent.FLAG_UPDATE_CURRENT
                );

I think that beside Ankit Gupta answer, you can use MediaSession (API > 21) to add native mediaController view :

notificationBuilder
        .setStyle(new Notification.MediaStyle()
            .setShowActionsInCompactView(new int[]{playPauseButtonPosition})  // show only play/pause in compact view
            .setMediaSession(mSessionToken))
        .setColor(mNotificationColor)
        .setSmallIcon(R.drawable.ic_notification)
        .setVisibility(Notification.VISIBILITY_PUBLIC)
        .setUsesChronometer(true)
        .setContentIntent(createContentIntent(description)) // Create an intent that would open the UI when user clicks the notification
        .setContentTitle(description.getTitle())
        .setContentText(description.getSubtitle())
        .setLargeIcon(art);

you can alse create custom view and display it in the notificcation area , first answer here is great.

Answer 5

    // It shows buttons on lock screen (notification).

Notification notification = new Notification.Builder(context)
    .setVisibility(Notification.VISIBILITY_PUBLIC)
    .setSmallIcon(R.drawable.NotIcon)
    .addAction(R.drawable.ic_prev, "button1",ButtonOneScreen) 
    .addAction(R.drawable.ic_pause, "button2", ButtonTwoScreen)  
   .....
    .setStyle(new Notification.MediaStyle()
    .setShowActionsInCompactView(1)
    .setMediaSession(mMediaSession.getSessionToken())
    .setContentTitle("your choice")
    .setContentText("Again your choice")
    .setLargeIcon(buttonIcon)
    .build();

I don't know if this is the right way or not, but it works.

1. Create a BroadCastReceiver class to receive the data when button is pressed.

public class MyBroadCastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        
        String log = "URI: " + intent.toUri(Intent.URI_INTENT_SCHEME);
        Log.d("my", "LOG:::::::" + log);
    }
}

2. Now in any activity where you want to create the notification -

 Intent intent = new Intent();
        intent.setAction("unique_id");
        intent.putExtra("key", "any data you want to send when button is pressed");
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, REQUEST_CODE, intent, 0);

3. Now use this pending intent when you are creating the notification and lastly you need to register this broadcast in order to receive it in MyBroadCastReceiver class.

BroadcastReceiver br = new MyBroadCastReceiver();
        IntentFilter filter = new IntentFilter("unique_id");
        registerReceiver(br, filter);

Now if you want to do certain things when the button is pressed, you can do so in the onReceive() method in MyBroadCastReceiver class.
