我必须在某个坐标 x,y 处修复弹出窗口，为此我使用了以下方法：
popupWindow.showAtLocation（锚，Gravity.NO_GRAVITY，位置[0]，位置[1]）
当回收器视图为空并且显示键盘时，弹出窗口显示在正确的位置，但遗憾的是，当回收器视图不为空并且显示键盘时，弹出窗口不会保持她的位置并且它向上移动
编辑：我使用了 showAtLocation，因为使用 showAsDropDown，popupView 在 ui 刷新期间也会跟随锚视图，这会导致从随机位置快速移动到正确位置。我已经尝试使用 showAtLocation 来解决 ax,y 坐标.. 你的解决方案我想我会遇到与 showAsDropDown 相同的问题
解决方案
您可以使用以下代码打开弹出窗口并设置锚视图以调整位置
private void openTeacherList() {
ArrayAdapter specializationAdapter = new ArrayAdapter(this,
android.R.layout.simple_spinner_dropdown_item, teacherNameList);
final ListPopupWindow popupWindow = new ListPopupWindow(this);
popupWindow.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView parent, View view, int position, long id)
{
binding.txtTeacher.setText(teacherNameList.get(position));
teacherId = teacherList.get(position).getId() + "";
popupWindow.dismiss();
}
});
popupWindow.setContentWidth(androidx.appcompat.widget.ListPopupWindow.WRAP_CONTENT);
popupWindow.setHeight(androidx.appcompat.widget.ListPopupWindow.WRAP_CONTENT);
popupWindow.setAnchorView(binding.txtTeacher);
popupWindow.setAdapter(specializationAdapter);
popupWindow.show();
}
