如何使声音像whatsapp通知声音

Question

我是新的android编程。我希望我的应用程序显示弹出通知（它可能称为抬头通知）在屏幕的顶部是否它在背景或前景中，并添加声音，但不知道如何。代码是非常基本的。

MyFirebaseMessageService.java

public class MyFirebaseMessageService extends FirebaseMessagingService { 

    public static final String TAG = "FCM"; 
    @Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
     // TODO: Handle FCM messages here. 

     // If the application is in the foreground handle both data and notification messages here. 
     // Also if you intend on generating your own notifications as a result of a received FCM 
     // message, here is where that should be initiated. 
     Log.d(TAG, "From: " + remoteMessage.getFrom()); 
     Log.d(TAG, "Notification Message: " + remoteMessage.getNotification().getBody()); 

    } 
} 

MyFirebaseIdService.java

public class MyFirebaseIDService extends FirebaseInstanceIdService { 

    private static String TAG = "INSTANCEID"; 


    @Override 
    public void onTokenRefresh() { 
     // Get updated InstanceID token. 

     String refreshedToken = FirebaseInstanceId.getInstance().getToken(); 
     Log.d(TAG, "Refreshed Token: " + refreshedToken); 

     // TODO: Implement this method to send any registration to your app's servers. 
     sendRegistrationToServer(refreshedToken); 
    } 



    private void sendRegistrationToServer(String token) { 

    } 
}

你想让你的通知在屏幕上，或在通知栏上？

对于简单的屏幕上的通知使用吐司。

Toast.makeText(getApplicationContext(),"Your message",Toast.LENGTH_SHORT).show(); 

For a notification bar notification take a look at NotificationBuilder. You can make your notification make sound as well.
