PS.我正在跟踪登录错误日志,但我的应用程序没有停止不幸,我的显示器继续向我显示视频正在加载进度栏我设置在Asynctask,但当我检查日志猫我看到这个错误.

当然我已经在谷歌搜索过以及SO但我没有得到满意的结果.

Folowwing是我的日志猫消息.

以下是我的代码.

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();
            }
        });

这是我播放视频的Asynctask

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);
        }
    }

以下是我的playVideo方法.

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();
    }

我也尝试在doInbackground方法中创建新线程并通过删除线程,但这个技巧对我不起作用.

还有一件事,它在第225行显示错误,即mc = new MediaController(this);
