  VideoView vvVideos =（VideoView）rootView.findViewById（R.id.videoView）;
        的MediaController的MediaController =新的MediaController（CTX）;
        mediacontroller.setAnchorView（vvVideos）;

   请帮助我。

解决方案

使用 seekTo（）显示第一帧。

确保视频暂停，然后用 seekTo（）来显示视频的第一帧：

  VideoView mVideoView =（VideoView）findViewById（R.id.video_ preVIEW）;

mVideoView.setVideoURI（yourVideoPath）;

mVideoView.seekTo（100）; // 100毫秒（0.1秒）插入剪辑。

i created an Videoview in my activity, below is the code.

        VideoView vvVideos = (VideoView) rootView.findViewById(R.id.videoView);
        MediaController mediacontroller = new MediaController(ctx);
        mediacontroller.setAnchorView(vvVideos);
            Uri video = Uri.parse("android.resource://" + packageName +"/"+R.raw.sample);
            vvVideos.setMediaController(mediacontroller);

            LayoutParams params=vvVideos.getLayoutParams();
            params.height=150;
            vvVideos.setLayoutParams(params);

            vvVideos.setVideoURI(video);
            vvVideos.requestFocus();
            vvVideos.setOnPreparedListener(new OnPreparedListener() {
                public void onPrepared(MediaPlayer mp) {
                    vvVideos.start();
                }
            });

Now the video gets started to play when the activity gets created. I want to make my activity as follows

1. Video should not play when the activity gets open.
2. It shoud display the starting video image(currently its displaying black color)
3. It should play only when the user click on the video.
   please help me.

解决方案

Use seekTo() to show the first frame.

Ensure the movie is paused and then use seekTo() to show the first frame of the video:

VideoView mVideoView = (VideoView) findViewById(R.id.video_preview);

mVideoView.setVideoURI(yourVideoPath);

mVideoView.seekTo(100);                 // 100 milliseconds (0.1 s) into the clip.
