中但是当我将该值传递给寄存器功能时，它没有取值如何做到这一点？请有人帮忙..！
答案 0 :(得分：0)
使用以下代码在异步类之外使用 setOnCheckedChangeListener 。
protected void onPostExecute(String result) {
if(!result.equals("null"){
((your activity name) activity).parseJsonResponse(result);
pDialog.dismiss();
}
}
并在您的活动中添加以下方法。
public void parseJsonResponse(String result) {
//use setOnCheckedChangeListener here.
}
