在TextureView上播放视频

Question

在Android TextureView的文档中,它说你可以使用TextureView来播放视频:但我似乎无法找到任何如何做到这一点的例子.有人知道吗？

我需要使用a,textureView因为我想为视频制作动画.我想播放.3gp/.mp4格式的视频,而不是来自相机的视频:)

任何帮助,将不胜感激..

以下是如何做到这一点:(问题作者的解决方案,他作为问题的更新发布)

Public class MediaPlayerDemo_Video extends Activity implements TextureView.SurfaceTextureListener {


 private MediaPlayer mMediaPlayer;

 private TextureView mPreview;

 @Override
 public void onCreate(Bundle icicle) {

      super.onCreate(icicle);

      mPreview = (TextureView) findViewById(R.id.surface);
      mPreview.setSurfaceTextureListener(this);
      extras = getIntent().getExtras();
      setContentView(mPreview);
 }

 @Override
 public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {
 Surface s = new Surface(surface);

 try {
       mMediaPlayer= new MediaPlayer();
       mMediaPlayer.setDataSource("http://daily3gp.com/vids/747.3gp");
       mMediaPlayer.setSurface(s);
       mMediaPlayer.prepare();
       mMediaPlayer.setOnBufferingUpdateListener(this);
       mMediaPlayer.setOnCompletionListener(this);
       mMediaPlayer.setOnPreparedListener(this);
       mMediaPlayer.setOnVideoSizeChangedListener(this);
       mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
       mMediaPlayer.start();
      } catch (IllegalArgumentException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (SecurityException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }   
} 

动画效果非常好.

Answer 2

我有同样的问题,用一个解决了TextureView.我发现setScaleX并且setScaleY非常有用,如果这有助于任何人.http://developer.android.com/reference/android/view/View.html#setScaleX%28float%29

但是,如果您仅定位API 16+:

mediaPlayer.setVideoScalingMode(MediaPlayer.VIDEO_SCALING_MODE_SCALE_TO_FIT_WITH_CROPPING);

应该这样做:)
