结合MediaPlayer类的简单播放器
public class SurfaceMediaPlayer extends Activity { SurfaceView surfaceView; MediaPlayer mediaPlayer; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_surface_media_player); mediaPlayer=new MediaPlayer(); surfaceView=(SurfaceView) this.findViewById(R.id.surfaceView1); surfaceView.getHolder().addCallback(new Callback() { @Override public void surfaceDestroyed(SurfaceHolder holder) { } @Override public void surfaceCreated(SurfaceHolder holder) { play(); } @Override public void surfaceChanged(SurfaceHolder h, int format, int w, int h) { } }); } private void play() { try { String path = Environment.getExternalStorageDirectory().getPath()+"/Movies/run_to_you.3gp"; mediaPlayer.setDataSource(path); mediaPlayer.setDisplay(surfaceView.getHolder());//视频画面输出到SurfaceView mediaPlayer.prepare(); mediaPlayer.start(); } catch (Exception e) { ……} } |
