使用TextureView代替VideoView. TextureView有getBitmap()方法.以下是TextureView作為videoView的用法

public class TextureVideoActivity extends Activity implements TextureView.SurfaceTextureListener {

private static final String FILE_NAME = "myVideo.mp4";

private static final String TAG = TextureVideoActivity.class.getName();

private MediaPlayer mMediaPlayer;

private TextureView mPreview;

@Override

public void onCreate(Bundle icicle) {

super.onCreate(icicle);

setContentView(R.layout.activity_texture_video);

mPreview = (TextureView) findViewById(R.id.textureView);

mPreview.setSurfaceTextureListener(this);

}

public Bitmap getBitmap(){

return mPreview.getBitmap();

}

public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {

Surface surface = new Surface(surfaceTexture);

try {

mMediaPlayer = new MediaPlayer();

mMediaPlayer

.setDataSource(this, Uri.parse(FILE_NAME));

mMediaPlayer.setSurface(surface);

mMediaPlayer.setLooping(true);

// don't forget to call MediaPlayer.prepareAsync() method when you use constructor for

// creating MediaPlayer

mMediaPlayer.prepareAsync();

// Play video when the media source is ready for playback.

mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

@Override

public void onPrepared(MediaPlayer mediaPlayer) {

mediaPlayer.start();

}

});

} catch (IllegalArgumentException e) {

Log.d(TAG, e.getMessage());

} catch (SecurityException e) {

Log.d(TAG, e.getMessage());

} catch (IllegalStateException e) {

Log.d(TAG, e.getMessage());

} catch (IOException e) {

Log.d(TAG, e.getMessage());

}

}

@Override

protected void onDestroy() {

super.onDestroy();

if (mMediaPlayer != null) {

// Make sure we stop video and release resources when activity is destroyed.

mMediaPlayer.stop();

mMediaPlayer.release();

mMediaPlayer = null;

}

}

@Override

public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int i, int i2) {

}

@Override

public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaceTexture) {

return false;

}

@Override

public void onSurfaceTextureUpdated(SurfaceTexture surfaceTexture) {

}

}
