java - ListView onItemSelected 监听器不工作

Question

尝试在弹出窗口中设置 ListView 的项目选定监听器时，我遇到了一些问题。这是我的代码:

private void openPopUp() {
    LayoutInflater layoutInflater = (LayoutInflater) getActivity()
            .getBaseContext().getSystemService(
                    context.LAYOUT_INFLATER_SERVICE);
    View popupView = layoutInflater.inflate(R.layout.event_attendee_pop,
            null);
    llAttendeeList = (LinearLayout) popupView
            .findViewById(R.id.llAttendeeList);
    attendeeListView = (ListView) popupView.findViewById(R.id.attendeelistview);

    final PopupWindow popupWindow = new PopupWindow(popupView,
            LayoutParams.WRAP_CONTENT, 450);

    popupWindow.showAtLocation(popupView, Gravity.BOTTOM, 0, 70);
    mAdapter = new ListAdapter(getActivity());
    attendeeListView.setAdapter(mAdapter);
    attendeeListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View item,
                int position, long id) {
            Log.i("HIIII","HIII");
            String telNo = attendeeList.get(position)
                    .getTelNo();
            Intent intentDialer = new Intent(Intent.ACTION_DIAL,Uri.parse("tel:1234-5678"));
            startActivity(intentDialer);
        }
    });
}

当从弹出窗口中的 ListView 中选择项目时，我想打开一个拨号页面。但是，当我通过放置日志消息对此进行测试时，当我从 ListView 中选择项目时，它不会执行项目选择的监听器。

有什么想法吗？提前致谢。

您必须使用另一个带有 boolean 参数的构造函数，该参数允许聚焦到 PopupWindow 项目:

public PopupWindow (View contentView, int width, int height, boolean focusable)

final PopupWindow popupWindow = new PopupWindow(popupView,LayoutParams.WRAP_CONTENT,450,true);
