Android MediaController Play/Pause button and Seekbar doesn't Refresh -

i using mediacontroller.mediaplayercontrol in order display mediacontroller @ bottom of custom view can't work properly. when play music first time there should pause button visible instead there play , when press button music paused correctly , state remains same , after working properly. when play next song, old mediacontroller widget gets overlapped new one. , progress/seek bar doesn't refresh while music playing. updates when on mediacontroller pressed (play/pause, forward, etc).

i found these questions similar mine don't think answers got solve problem.

1. android mediacontroller play pause controls not refresh properly
2. android mediacontroller seekbar not refreshing
3. android videoview playback controls show "play" instead of "pause" though file playing

this how initialize controller:

private void setcontroller() {     controller = new musiccontroller(this);      controller.setprevnextlisteners(new view.onclicklistener() {           @override           public void onclick(view v) {             playnext();           }         }, new view.onclicklistener() {           @override           public void onclick(view v) {             playprev();           }         });      controller.setmediaplayer(this);     controller.setanchorview(findviewbyid(r.id.song_list));     controller.setenabled(true); } 

this how show controller:

public void playmusic() {         musicsrv.playsong(); //play song in service         setcontroller();         controller.show(0);         controller.requestfocus(); } 

i had problem. don't know if still need help, thought i'd post anyway. posterity, following this tutorial?

first, easy problem: you're getting multiple instances of controls because of repeated calls setcontroller(). change first line of function to:

if (controller == null) controller = new musiccontroller(this); 

with regards play button malfunctioning, believe it's because you're showing before music player has been prepared (disclaimer: i'm newbie android myself, , following things i've found have worked).

1. set broadcast music-playing service notify music-controlling activity when musicplayer has been prepared. append following function in music-playing service broadcast intent:

   @override public void onprepared(musicplayer player) {     // other stuff...      // broadcast intent activity let know media player has been prepared     intent onpreparedintent = new intent("media_player_prepared");     localbroadcastmanager.getinstance(this).sendbroadcast(onpreparedintent); } 

2. set broadcast receiver in music-controlling activity receive intent broadcast service. add following class activity:

   // broadcast receiver determine when music player has been prepared private broadcastreceiver onpreparereceiver = new broadcastreceiver() { @override public void onreceive(context c, intent i) {     // when music player has been prepared, show controller     controller.show(0);     } }; 

3. register receiver in activity's onresume() method:

   // set receiver media player onprepared broadcast localbroadcastmanager.getinstance(this).registerreceiver(onpreparereceiver,         new intentfilter("media_player_prepared")); 

4. depending on structure of code, you'll have general tidying up. in code, i've called setcontroller() twice: oncreate() , onresume() methods in activity. call controller.show(0) broadcast receiver, , onresume() method.
