如何在通知栏中显示歌曲名称和艺术家姓名
我已经创建了一个流式音乐播放器，可以从Firebase播放歌曲。现在我创建了一个自定义通知，在通知栏上显示歌曲详情。歌曲详情应显示在应用程序内部，但不显示通知栏的详细信息。我怎么能把行动发挥，停止音乐。任何人都可以告诉我如何修复我现有的解决方案。如何在通知栏中显示歌曲名称和艺术家姓名
这是我的通知栏代码。
public class NotificationService extends Service { @Override
public void onDestroy() {
super.onDestroy();
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getAction().equals(NConstants.ACTION.STARTFOREGROUND_ACTION)) {
showNotification();
Toast.makeText(this, "Service Started", Toast.LENGTH_SHORT).show();
} else if (intent.getAction().equals(NConstants.ACTION.PREV_ACTION)) {
Toast.makeText(this, "Clicked Previous", Toast.LENGTH_SHORT).show();
Log.i(LOG_TAG, "Clicked Previous");
} else if (intent.getAction().equals(NConstants.ACTION.PLAY_ACTION)) {
Toast.makeText(this, "Clicked Play", Toast.LENGTH_SHORT).show();
Log.i(LOG_TAG, "Clicked Play");
} else if (intent.getAction().equals(NConstants.ACTION.NEXT_ACTION)) {
Toast.makeText(this, "Clicked Next", Toast.LENGTH_SHORT).show();
Log.i(LOG_TAG, "Clicked Next");
} else if (intent.getAction().equals(
NConstants.ACTION.STOPFOREGROUND_ACTION)) {
Log.i(LOG_TAG, "Received Stop Foreground Intent");
// Toast.makeText(this, "Service Stoped", Toast.LENGTH_SHORT).show();
stopForeground(true);
stopSelf();
}
return START_STICKY;
}
Notification status;
private final String LOG_TAG = "NotificationService";
@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
private void showNotification() {
// Using RemoteViews to bind custom layouts into Notification
RemoteViews views = new RemoteViews(getPackageName(),
R.layout.status_bar);
RemoteViews bigViews = new RemoteViews(getPackageName(),
R.layout.status_bar_expanded);
// showing default album image
views.setViewVisibility(R.id.status_bar_icon, View.VISIBLE);
views.setViewVisibility(R.id.status_bar_album_art, View.GONE);
bigViews.setImageViewBitmap(R.id.status_bar_album_art,
NConstants.getDefaultAlbumArt(this));
Intent notificationIntent = new Intent(this, ViewUploadsActivity.class);
notificationIntent.setAction(NConstants.ACTION.MAIN_ACTION);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
notificationIntent, 0);
Intent previousIntent = new Intent(this, NotificationService.class);
previousIntent.setAction(NConstants.ACTION.PREV_ACTION);
PendingIntent ppreviousIntent = PendingIntent.getService(this, 0,
previousIntent, 0);
Intent playIntent = new Intent(this, NotificationService.class);
playIntent.setAction(NConstants.ACTION.PLAY_ACTION);
PendingIntent pplayIntent = PendingIntent.getService(this, 0,
playIntent, 0);
Intent nextIntent = new Intent(this, NotificationService.class);
nextIntent.setAction(NConstants.ACTION.NEXT_ACTION);
PendingIntent pnextIntent = PendingIntent.getService(this, 0,
nextIntent, 0);
Intent closeIntent = new Intent(this, NotificationService.class);
closeIntent.setAction(NConstants.ACTION.STOPFOREGROUND_ACTION);
PendingIntent pcloseIntent = PendingIntent.getService(this, 0,
closeIntent, 0);
views.setOnClickPendingIntent(R.id.status_bar_play, pplayIntent);
bigViews.setOnClickPendingIntent(R.id.status_bar_play, pplayIntent);
views.setOnClickPendingIntent(R.id.status_bar_next, pnextIntent);
bigViews.setOnClickPendingIntent(R.id.status_bar_next, pnextIntent);
views.setOnClickPendingIntent(R.id.status_bar_prev, ppreviousIntent);

views.setOnClickPendingIntent(R.id.status_bar_collapse, pcloseIntent);

views.setImageViewResource(R.id.status_bar_play,
R.drawable.ic_pause);
bigViews.setImageViewResource(R.id.status_bar_play,
R.drawable.ic_play);
views.setTextViewText(R.id.status_bar_track_name,"Name"); // How i can
displpay the song name here
bigViews.setTextViewText(R.id.status_bar_track_name,"Name");
views.setTextViewText(R.id.status_bar_artist_name, "Artist");
bigViews.setTextViewText(R.id.status_bar_artist_name,"Artist");
status = new Notification.Builder(this).build();
status.contentView = views;
status.bigContentView = bigViews;
status.flags = Notification.FLAG_ONGOING_EVENT;
status.icon = R.drawable.images;
status.contentIntent = pendingIntent;
startForeground(NConstants.NOTIFICATION_ID.FOREGROUND_SERVICE, status);
}
}
这里是我的那类，获取歌曲的URL和细节 这是一个是获取数据的类。
public void get() {
seekBarProgress.setMax(99); // It means 100% .0-99
seekBarProgress.setOnTouchListener(this);
mMediaPlayer.setOnBufferingUpdateListener(this);
mMediaPlayer.setOnCompletionListener(this);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@SuppressLint("RestrictedApi")
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
//getting the upload
Upload upload = uploadList.get(i);
mSelectedTrackTitle.setText(upload.getName());
selected_track_ar.setText(upload.getAr());
if (mMediaPlayer.isPlaying()) {
mMediaPlayer.stop();
mMediaPlayer.reset();
seekBarProgress.setProgress(0);
}
try {
mMediaPlayer.setDataSource(upload.getUrl());
mMediaPlayer.prepare();
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
@Override
public boolean onTouch(View v, MotionEvent event) {
if(v.getId() == R.id.length){
/** Seekbar onTouch event handler. Method which seeks MediaPlayer to seekBar primary progress position*/
if(mMediaPlayer.isPlaying()){
SeekBar sb = (SeekBar)v;
int playPositionInMillisecconds = (mediaFileLengthInMilliseconds/100) * sb.getProgress();
mMediaPlayer.seekTo(playPositionInMillisecconds);
}
}
return false;
}
@Override
public void onBufferingUpdate(MediaPlayer mp, int percent) {
seekBarProgress.setSecondaryProgress(percent);
}
@Override
public void onCompletion(MediaPlayer mp) {
}
当你看到这首歌的细节应该是在应用程序中显示，但在通知栏不显示：
回答：
你需要做的是，当你设置自定义查看您的通知，您需要像这样同时填充数据。
RemoteViews customView = new RemoteViews(getPackageName(), R.layout.custom_layout); customView.setTextViewText(R.id.track_name, "My fav music");
customView.setTextViewText(R.id.artist_name, "My fav artist");
Notification notification = new NotificationCompat.Builder(this).setContent(customView).allOtherMethods().build();
notificationManager.notify(1, notification);
