推荐答案

刚刚使用，而不是VideoView的MediaPlayer，并使用MediaPlayer.setSurface而不是MediaPlayer.setDisplay。如果您使用setDisplay在MediaPlayer改掉告诉SurfaceHolder保持上这是不允许的LiveWallpapers屏幕，将抛出一个错误。

Just use MediaPlayer instead of VideoView and use MediaPlayer.setSurface instead of MediaPlayer.setDisplay. If you use setDisplay the MediaPlayer trys to tell the SurfaceHolder to keep the screen on which isn't allowed for LiveWallpapers and will throw an error.

我用的WebM / vpx8视频但这应该工作与任何MediaPlayer的支持（只是把水库视频文件/ RAW）

I use WebM/vpx8 video but this should work with whatever MediaPlayer supports (just put the video file in res/raw)

package com.justinbuser.nativecore;

import android.media.MediaPlayer;
import android.service.wallpaper.WallpaperService;
import android.view.SurfaceHolder;
import com.justinbuser.android.Log;

public class VideoWallpaperService extends WallpaperService
    {
        protected static int                playheadTime = 0;

        @Override
        public Engine onCreateEngine()
            {
                return new VideoEngine();
            }

        class VideoEngine extends Engine
            {

                private final String        TAG     = getClass().getSimpleName();
                private final MediaPlayer   mediaPlayer;
                public VideoEngine()
                    {
                        super();
                        Log.i( TAG, "( VideoEngine )");
                        mediaPlayer = MediaPlayer.create(getBaseContext(), R.raw.wallpapervideo);
                        mediaPlayer.setLooping(true);
                    }

                @Override
                public void onSurfaceCreated( SurfaceHolder holder )
                    {
                        Log.i( TAG, "onSurfaceCreated" );
                        mediaPlayer.setSurface(holder.getSurface());
                        mediaPlayer.start();
                    }

                @Override
                public void onSurfaceDestroyed( SurfaceHolder holder )
                    {
                        Log.i( TAG, "( INativeWallpaperEngine ): onSurfaceDestroyed" );
                        playheadTime = mediaPlayer.getCurrentPosition();
                        mediaPlayer.reset();
                        mediaPlayer.release();
                    }
        }

}
