Andriod中用AlertDialog弹窗出现子类多个父类异常

异常：：java.lang.IllegalStateException: The specified child already has a parent.
                                                          You must call removeView() on the child's parent first.

解决方法：把申明加入弹窗事件加入到（引起/触发弹窗）监听事件中

 pop_up_change_name=View.inflate(this,R.layout.pop_up_change_name,null);
 change_name_dialog.setView(pop_up_change_name).create();//弹窗加入view
 show=change_name_dialog.show();//通过AlertDialog.builder弹窗的显示要赋给show（AlertDialog）

 btn_change_name_sure=(Button) pop_up_change_name.findViewById(R.id.btn_change_name_sure);
 ed_change_name=pop_up_change_name.findViewById(R.id.ed_change_name);
 btn_change_name_sure.setOnClickListener(this);
 break;
