android - 如何在 android 中单击图像按钮时从视频 url 播放视频？

Question

我有一个图像按钮和视频 url。我希望当用户单击图像按钮时播放该视频。如果该视频流结束，我希望该视频在相同的 Activity 中播放，然后我必须返回相同的 Activity 。

VideoView 视频 View ； ImageView btnWatchVideo;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_promotions_feed);

    btnWatchVideo = (ImageView) findViewById(R.id.btnWatchVideo);

    videoView = (VideoView) findViewById(R.id.ltVideoUrl);

    String path1 = "https://d1e6yi6s3cx2ur.cloudfront.net/videos/0/_20160316_ios-user.m4v";
    MediaController mc = new MediaController(this);
    mc.setAnchorView(videoView);
    mc.setMediaPlayer(videoView);
    Uri uri = Uri.parse(path1);
    videoView.setMediaController(mc);
    videoView.setVideoURI(uri);
    btnWatchVideo.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            videoView.start();
        }

    });

此代码无效。任何人都可以建议我如何做到这一点。

尝试对两个 Activity 使用这两个 onCreate 方法。

视频观看 Activity

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video);
        videoView = (VideoView) findViewById(R.id.ltVideoUrl);
        String path1 = "https://d1e6yi6s3cx2ur.cloudfront.net/videos/0/_20160316_ios-user.m4v";
        MediaController mc = new MediaController(this);
        mc.setAnchorView(videoView);
        mc.setMediaPlayer(videoView);
        Uri uri = Uri.parse(path1);
        videoView.setMediaController(mc);
        videoView.setVideoURI(uri);
        videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
             @Override
             public void onPrepared(MediaPlayer mp) {
                 videoView.start();
             }
         });}

主要 Activity

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btnWatchVideo = (ImageView) findViewById(R.id.btnWatchVideo);
        btnWatchVideo.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                startActivity(new Intent(MainActivity.this, VideoActivity.class));
            }
        });}
