滚动后，ListView再次进入第一个位置

Question

大家好我在我的应用程序中有listview但滚动到底部后再次设置为第一个位置。

    listView = (ListView) findViewById(R.id.list);
    start = listView.getFirstVisiblePosition();
    listView.setSelectionFromTop(start, 0);

删除以下代码后，它工作正常，但滚动后setOnItemClickListener不起作用。

listView.setOnScrollListener(new OnScrollListener() {
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            if ( scrollState == OnScrollListener.SCROLL_STATE_IDLE )
            {
              listView.invalidateViews();
            }

        }

        @Override
        public void onScroll(AbsListView arg0, int arg1, int arg2, int arg3) {}




    });

任何建议将不胜感激。提前致谢

请尝试这种方式，希望这有助于您解决问题。

listView.setOnScrollListener(new AbsListView.OnScrollListener() {
   @Override
   public void onScrollStateChanged(AbsListView view, int scrollState) {
   }

   @Override
   public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
       int lastInScreen = firstVisibleItem + visibleItemCount;
       if((lastInScreen == totalItemCount)){
          new Handler().postDelayed(new Runnable() {
              @Override
              public void run() {
                    listView.smoothScrollToPosition(0);
              }
           },1000); // change (1000) value as per your requirement like : when list shown last item then after 1 second list scrolled to 0 position
        }
    }
});
