android - 为什么setOnCheckedChangeListener在使用LayoutInflater的弹出窗口中不起作用？

我在弹出窗口中有一个放射组。当我放置setoncheckedchangelister时，它会导致一个错误。这是我的密码。错误说明它不适用于参数（new compound button.onCheckedChangeListener..我不明白有人能帮我吗？

   private void showPopupSeat(final Activity context)
   {
       int popupWidth = 500;
       int popupHeight = 650;


   // Inflate the popup_layout.xml
   LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.popupseat);


   LayoutInflater layoutInflater = (LayoutInflater) context
     .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
   View layout = layoutInflater.inflate(R.layout.seat_dimension, viewGroup);


  RadioGroup rg = (RadioGroup) layout.findViewById(R.id.rg1);
  final RadioButton rb1 = (RadioButton) layout.findViewById(R.id.option1);
  final RadioButton rb2 = (RadioButton) layout.findViewById(R.id.option2);
  final RadioButton rb3 = (RadioButton) layout.findViewById(R.id.option3);

      rg.setOnCheckedChangeListener(new OnCheckedChangeListener()
      {
          public void onCheckedChanged(RadioGroup group, int checkedId) {

          }
  });


   final PopupWindow popupseat = new PopupWindow(context);
   popupseat.setContentView(layout);
   popupseat.setWidth(popupWidth);
   popupseat.setHeight(popupHeight);
   popupseat.setFocusable(true);


   // Some offset to align the popup a bit to the right, and a bit down, relative to button's position.
   int OFFSET_X = 30;
   int OFFSET_Y = 260;

     // Clear the default translucent background
   popupseat.setBackgroundDrawable(new BitmapDrawable());

   // Displaying the popup at the specified location, + offsets.
   popupseat.showAtLocation(layout, Gravity.CENTER, 0, 0);
  }

我不知道怎么了。请帮忙。

最佳答案

而是导入
import android.widget.CompoundButton.OnCheckedChangeListener;
进口
import android.widget.RadioGroup.OnCheckedChangeListener;
