使用MediaPlayer和SurfaceView结合播放视频

界面布局代码：

Activity代码和解释如下：

public class MediaPlayerAndSurfaceViewActivity extends Activity implements View.OnClickListener{
    SurfaceView surfaceView;
    Button startBtn,pauseBtn,stopBtn;
    MediaPlayer mediaPlayer;
    int position;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mediaplayer_surfaceview);
        startBtn = (Button) findViewById(R.id.btn_start);
        pauseBtn = (Button) findViewById(R.id.btn_pause);
        stopBtn = (Button) findViewById(R.id.btn_stop);
        startBtn.setOnClickListener(this);
        pauseBtn.setOnClickListener(this);
        stopBtn.setOnClickListener(this);
        mediaPlayer = new MediaPlayer();
        surfaceView = (SurfaceView) findViewById(R.id.surfaceView);
        //  设置播放时打开屏幕
        surfaceView.getHolder().setKeepScreenOn(true);
        //  为SurfaceView添加监听
        surfaceView.getHolder().addCallback(new SurfaceListener());
    }

    private void play(){
        mediaPlayer.reset();
        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        try {
            //  MediaPlayer设播放的资源
            mediaPlayer.setDataSource("/storage/sdcard1/相机/录像/video_20130406_075740.3gp");
            //  将视频画面输出到SurfaceView
            mediaPlayer.setDisplay(surfaceView.getHolder());
            mediaPlayer.prepare();
            //  以下两句是 To access the DisplayMetrics members
            DisplayMetrics metrics = new DisplayMetrics();
            getWindowManager().getDefaultDisplay().getMetrics(metrics);
            //  设置视频保持纵横比缩放到占满屏幕
            surfaceView.setLayoutParams(new RelativeLayout.LayoutParams(metrics.widthPixels
                    ,mediaPlayer.getVideoHeight() * metrics.widthPixels
                    /mediaPlayer.getVideoWidth()));
            mediaPlayer.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    @Override
    public void onClick(View v) {
        switch (v.getId())
        {
            case R.id.btn_start:
                play();
                break;
            case R.id.btn_pause:
                if(mediaPlayer.isPlaying()){
                    mediaPlayer.pause();
                }else{
                    mediaPlayer.start();
                }
                break;
            case R.id.btn_stop:
                if(mediaPlayer.isPlaying())
                    mediaPlayer.stop();
                break;
        }
    }
    private class SurfaceListener implements SurfaceHolder.Callback{

        @Override
        public void surfaceCreated(SurfaceHolder holder) {
            if(position > 0){
                play();
                //  从指定位置播放
                mediaPlayer.seekTo(position);
                position = 0;
            }
        }

        @Override
        public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {

        }

        @Override
        public void surfaceDestroyed(SurfaceHolder holder) {

        }
    }
    //当跳到其他页面时,保存当前的播放位置
    @Override
    protected void onPause() {
        super.onPause();
        if(mediaPlayer.isPlaying()){
            position = mediaPlayer.getCurrentPosition();
            mediaPlayer.stop();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if(mediaPlayer.isPlaying()) mediaPlayer.stop();
        //  释放MediaPlayer所占资源
        mediaPlayer.release();
    }
}

注：这种方式播放视频真麻烦，不推荐使用，推荐使用VedioView和MediaController结合的方式播放视频
