我正在开发一个音乐播放器应用程序,它可以很好地播放音乐,但是当它在后台播放时,问题就来了,一段时间后它停止了....我在网上搜索过如何解决这个问题,几乎他们所有人都在使用服务而不是活动,我不想那样做,那么我该如何实现呢?
这是我正在使用的代码
public class NowPlaying extends Activity implements Serializable {
static MediaPlayer mp =new MediaPlayer();
/*SeekBar songProgressBar = (SeekBar) findViewById(R.id.songProgressBar);
TextView songCurrentDurationLabel = (TextView) findViewById(R.id.songCurrentDurationLabel);
TextView songTotalDurationLabel = (TextView) findViewById(R.id.songTotalDurationLabel);
private Handler mHandler = new Handler();
private Utilities utils;
*/
@SuppressLint("NewApi")
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.now_playing);
Intent i = getIntent();
final int position=i.getIntExtra("Data2", 0);
final ArrayList<SongDetails> songs = getIntent().getParcelableArrayListExtra("Data1");
SongDetails songDetails = songs.get(position) ;
Button bfake=(Button) findViewById(R.id.bFake);
LinearLayout LL=(LinearLayout) findViewById(R.id.LL);
Button Pause=(Button)findViewById(R.id.bPlayPause);
Playservice(songs,position,0 );
bfake.setOnTouchListener(new OnSwipeTouchListener()
{ int z=0;
public void onSwipeRight() {
z=z-1;
Playservice(songs,position,z );
}
public void onSwipeLeft() {
z=z+1;
Playservice(songs,position,z );
}
public void onSwipeBottom() {
mp.stop();
}
});
LL.setOnTouchListener(new OnSwipeTouchListener() {
public void onSwipeBottom() {
mp.stop();
}
});
Pause.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v)
{if(mp.isPlaying())
mp.pause();
else
mp.start();
}
});
}
private void Playservice( ArrayList<SongDetails> songs, int position, int i )
{
/* Utilities utils = new Utilities();
songProgressBar.setOnSeekBarChangeListener((OnSeekBarChangeListener) this); // Important
*///mp.setOnCompletionListener((OnCompletionListener) this);
try {
String ab=songs.get(position+i).getPath2().toString();
if(mp.isPlaying())
{ mp.stop();
}
mp.reset();
mp.setDataSource(ab) ;
mp.prepare();
mp.start();
