推荐答案

您可以尝试获得一些框出你的视频，就像这样：

You can try to get some frame out of your video just like this:

    Uri  videoURI = Uri.parse("android.resource://" + getPackageName() +"/"
            +R.raw.cashword_video);
    MediaMetadataRetriever retriever = new MediaMetadataRetriever();
    retriever.setDataSource(this, videoURI);
    Bitmap bitmap = retriever
          .getFrameAtTime(100000,MediaMetadataRetriever.OPTION_PREVIOUS_SYNC);
    Drawable drawable = new BitmapDrawable(getResources(), bitmap);
