我真的很震惊这个问题.. 我有一个列表视图，其中包含一个按钮，当单击该按钮时，它应显示一个弹出窗口。我已经实现了列表视图，但弹出窗口没有显示在单击的按钮位置..
下面给出的示例代码
public View getView(int position, View convertView, final ViewGroup parent) {
View vi=convertView;
if(convertView==null)
vi = inflater.inflate(R.layout.list_row, null);
vi.findViewById(R.id.statusImage).setOnTouchListener(new View.OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
x=(int) event.getX();
y=(int) event.getY();
showPopup(x,y);// calls popup
return false;
public void showPopup(int xk , int ys) {
LayoutInflater inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.popup_layout,null);
pwindo = new PopupWindow(layout, 300, 250, true);
pwindo.showAtLocation(layout, Gravity.NO_GRAVITY, xk,ys);

event.getY（）返回相对于父项的Y位置，所以我们必须找到被点击的行的位置和每行的高度来计算y位置。
此代码显示弹出窗口，在该弹出窗口中单击了行imageview，并且通过littele修改它将是您的用途。

将其用于弹出窗口：
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(x + " - " + Y)
.setPositiveButton("ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
})
builder.create();
