当时播放以下项目视频，如下所示：

当我点击任何项目但我在日志中找到正确位置时，我检查了日志中的位置，那么我该怎么办？请大家帮忙解决一下。我很多天都遇到过这个问题

我的代码如下：

public class PlayVideo extends Activity {
        private Activity mActivity;
        private static final boolean SHOW_LOGS = Config.SHOW_LOGS;
        private static final String TAG = PlayVideo.class.getSimpleName();
        private ArrayList<BaseVideoItem> mList = new ArrayList<>();
        private String videoId = "";
        public static int isVideoPlay = 0;
        public static ProgressDialog pDialog;
     private final ListItemsVisibilityCalculator mListItemVisibilityCalculator =
                new SingleListViewItemActiveCalculator(new DefaultSingleItemCalculatorCallback(), mList);
    private ItemsPositionGetter mItemsPositionGetter;

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

            mActivity = PlayVideo.this;

            pDialog = new ProgressDialog(mActivity);
            pDialog.setMessage("Loading");
            pDialog.setCanceledOnTouchOutside(false);
            pDialog.setCancelable(true);

            try {
                mList.add(ItemFactory.createItemFromUrl(mActivity, "http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4", R.drawable.video_sample_1_pic, mActivity, mVideoPlayerManager));
