    android:layout_width="match_parent"
    android:layout_height="251dp"
    android:layout_gravity="center_horizontal"

// 加载视屏

Uri uri = Uri.parse(videoUrl);
VideoView videoView = this.findViewById(R.id.videoView);
//设置视频控制器
videoView.setMediaController(new MediaController(this));
//播放完成回调
videoView.setOnCompletionListener(new MyPlayerOnCompletionListener());
//设置视频路径
videoView.setVideoURI(uri);
//开始播放视频
Button button6 = findViewById(R.id.button6);
button6.setOnClickListener(view -> {
    videoView.start();
});

class MyPlayerOnCompletionListener implements MediaPlayer.OnCompletionListener {
    @Override
    public void onCompletion(MediaPlayer mp) {
        Toast.makeText( LocalVideoActivity.this, "播放完成了", Toast.LENGTH_SHORT).show();
