在activity里使用，radio是点击出现弹窗的控件，也可以是TextView或者其他，传入这个参数是为了做选中的效果。

FilterPopupWindow orderFilterPopupWindow ;
    private void setPopupWindow( List list1, RadioButton radio, int spanCount) {
        orderFilterPopupWindow = new FilterPopupWindow(this, list1, realFilter,spanCount,radio.getText().toString());
        orderFilterPopupWindow.showAsDropDown(realFilter);

        orderFilterPopupWindow.setOnFilterPopupWindowListener(new FilterPopupWindow.OnFilterPopupWindowListener() {
            @Override
            public void getText(String string, int position) {
                orderFilterPopupWindow.dismiss();
                if (string == null){
                    return;
                }
                
                }
                orderFilterPopupWindow.dismiss();
            }
        });
    }
