我遇到了問題，當我使用mediaplayer與我的應用程序一起播放視頻時。有時候視頻播放會很好，但有些時候會出現黑屏。它不是我打電話給視頻的文件，因爲我已經在同一個文件上進行了測試，它有時可用，有時不起作用。我覺得這個問題最常發生在我玩過幾部影片後。在問題開始之前，我通常會玩3-4。我想知道是什麼導致了這種情況，以及我如何解決這個問題。我的代碼發佈在下面。Mediaplayer有時不起作用
public class FullImageActivity extends Activity implements SurfaceHolder.Callback, OnPreparedListener, OnErrorListener{
private static final String TAG = null;
MediaPlayer player;
SurfaceView surfaceview;
SurfaceHolder surfaceHolder;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.full_image);
Intent i = getIntent();
long id = i.getExtras().getLong("id");
String path = i.getExtras().getString("videopath");
surfaceview = (SurfaceView)findViewById(R.id.surfaceview);
surfaceHolder = surfaceview.getHolder();
surfaceHolder.addCallback(this);
player = new MediaPlayer();
try {
player.reset();
player.setOnErrorListener(this);
player.setDataSource(path);
player.setOnPreparedListener(this);
player.prepare();
player.start();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
}
@Override
public void surfaceCreated(SurfaceHolder holder) {
player.setDisplay(holder);
}
@Override
public void surfaceDestroyed(SurfaceHolder arg0) {
// TODO Auto-generated method stub
}
@Override
public void onPrepared(MediaPlayer p) {
}
@Override
public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
Log.i(TAG, "THERE WAS AN ERROR");
return false;
}
謝謝。
