listview 获取item坐标

listview 获取item坐标

当listview高度是固定的,上拉item后,就很难计算拉动后的item坐标了
private void initPop(View v,int position){
View popupWindow_view =inflater.inflate(R.layout.login, null);
PopupWindow popupWindow = new PopupWindow(popupWindow_view, getWindowManager().getDefaultDisplay().getWidth() 3/5, 152, true);

popupWindow.setTouchable(true);
popupWindow.setBackgroundDrawable(new BitmapDrawable()); //
popupWindow.setFocusable(true);
TextView text1= (TextView)popupWindow_view.findViewById(R.id.text1);
TextView text2= (TextView)popupWindow_view.findViewById(R.id.text2);
text1.setText(list1.get(index).get(position).get("text1").toString());
text2.setText(list1.get(index).get(position).get("text2").toString());
popupWindow.showAsDropDown (edit1,getWindowManager().getDefaultDisplay().getWidth() /5,v.getHeight()
(position%11+1));//问题主要在这一句,目的在item下弹出popupwindow,可是当拖地item后,再长按就不能计算正确出item的位置了,各位有什么好的计算方法望赐教!谢谢了。

              }

public  void pop(View v) {//按钮1事件
    popup();
        }

 public   boolean onItemLongClick(AdapterView<?> arg0, View arg1,int arg2,long arg3) {
        initPop(arg1,arg2);
       click=arg2;
        adapter.notifyDataSetChanged();
                          return true; 
                   }

本人以解决

()  popupWindow.showAsDropDown (edit1,getWindowManager().getDefaultDisplay().getWidth() /5,(v.getHeight()+1)*(position-listView.getFirstVisiblePosition() +1/4));//位于et下面

关键代码
(v.getHeight()+1)*(position-listView.getFirstVisiblePosition() +1/4)
item的高度乘(当前游标-顶部游标)
