How to add button to notifications in android?

Android Problem Overview

My app plays music and when users open notifications screen by swiping from the top of the screen ( or generally from the bottom right of the screen on tablets ), I want to present them a button to stop the currently playing music and start it again if they want.

I am not planning to put a widget on the user's home screen, but just into notifications. How can I do this?

You can create an intent for the action (in this case stop playing) and then add it as an action button to your 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);

Please refer to the Android documentation.

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 :)

    // 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();

tested, working code with android Pie. These all go inside the same service class.

Show a notification:

public void setNotification() {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
	{
	NotificationChannel channel = new NotificationChannel("a", "status", NotificationManager.IMPORTANCE_DEFAULT);
	channel.setDescription("notifications");
	notificationManager = getSystemService(NotificationManager.class);
	notificationManager.createNotificationChannel(channel);

	}
else
	notificationManager =  (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);


Receiver.service = this;
Notification.MediaStyle style = new Notification.MediaStyle();

notification = new Notification.Builder(this)
		.setSmallIcon(R.mipmap.ic_launcher)
		.setContentTitle("Notification")
		.addAction(R.drawable.close_icon,  "quit_action", makePendingIntent("quit_action"))
		.setStyle(style);

style.setShowActionsInCompactView(0);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
	{
	notification.setChannelId("a");
	}

// notificationManager.notify(123 , notification.build()); // pre-oreo
startForeground(126, notification.getNotification());
}

Helper function:

public PendingIntent makePendingIntent(String name)
	{
	Intent intent = new Intent(this, FloatingViewService.Receiver.class);
	intent.setAction(name);
	PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
	return pendingIntent;
	}

To handle the actions:

static public class Receiver extends BroadcastReceiver {
static FloatingViewService service;

@Override
public void onReceive(Context context, Intent intent)
	{

	String whichAction = intent.getAction();

	switch (whichAction)
		{
	
		case "quit_action":
			service.stopForeground(true);
			service.stopSelf();
			return;

		}

	}
}

You'll need to update your manifest too:

<receiver android:name=".FloatingViewService$Receiver">
        <intent-filter>
            <action android:name="quit_action" />
        </intent-filter>
    </receiver>

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.

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

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);
    }
}

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);

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.
