和以下是我的code。

And following is my code.

mListView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {

                    String url1 = null;
                    Object o1 = myList.get(position);
                    url1 = o1.toString().replace(" ", "%20").trim();
                    playVideo = (PlayVideo) new PlayVideo(url1).execute();
            }
        });

这是我的AsyncTask来的playVideo

and this is my Asynctask to playvideo

class PlayVideo extends AsyncTask<String, Void, Boolean> {

        String baseURL;

        public PlayVideo(String baseURL) {
            this.baseURL = baseURL;
        }

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            pDialog = ProgressDialog.show(ServerFileList.this,
                    "    Buffering...", "please wait..", false);
            pDialog.setCancelable(false);

        }

        @Override
        protected Boolean doInBackground(String... urls) {

            Thread thread = new Thread(new Runnable() {
                @Override
                public void run() {
                    try {
                        playVideo(baseURL);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            });
            thread.start();

            return true;
        }

        @Override
        protected void onPostExecute(Boolean result) {
            super.onPostExecute(result);
        }
    }

和以下是我的playVideo方法。

and following is my playVideo method.

private void playVideo(String baseURL) {
        Uri myUri = Uri.parse(baseURL);
        MediaController mc;

        mc = new MediaController(this);
        mVideoView.setMediaController(mc);
        mVideoView.setVideoURI(myUri);
        System.out.println("====Myuri=====" + myUri);
        mVideoView.requestFocus();
        mVideoView.start();
    }

我也试图创造doInBackground方法新线程，并还准备卸下线程，但这种技巧并不为我工作。

I also tried to creating new thread in doInbackground method and by removing thread also, but this tricks does not worked for me.

还一件事，它显示在线路225错误是 MC =新的MediaController（本）;

also one thing that it showing error on line 225 that is mc = new MediaController(this);

推荐答案

您可以删除您的AsyncTask，并直接播放视频使用下面code，

You can remove your AsyncTask and play your video directly using below code,

String url1 = null; 
Object o1 = myList.get(position); 
url1 = o1.toString().replace(" ", "%20").trim(); 
playVideo(url1);
