如何让AlertDialog 在点击确定或者取消时不消失

查看AlertDialog的源代码，如下：

 /**
         * Set a listener to be invoked when the positive button of the dialog is pressed.
         * @param textId The resource id of the text to display in the positive button
         * @param listener The {@link DialogInterface.OnClickListener} to use.
         *
         * @return This Builder object to allow for chaining of calls to set methods
         */
        public Builder setPositiveButton(int textId, final OnClickListener listener) {
            P.mPositiveButtonText = P.mContext.getText(textId);
            P.mPositiveButtonListener = listener;
            return this;
        }
               
        public Builder setPositiveButton(CharSequence text, final OnClickListener listener) {
            P.mPositiveButtonText = text;
            P.mPositiveButtonListener = listener;
            return this;
        }
       
        public Builder setNegativeButton(int textId, final OnClickListener listener) {
            P.mNegativeButtonText = P.mContext.getText(textId);
            P.mNegativeButtonListener = listener;
            return this;
        }
              
        public Builder setNegativeButton(CharSequence text, final OnClickListener listener) {
            P.mNegativeButtonText = text;
            P.mNegativeButtonListener = listener;
            return this;
        }

注意看注释第一句：Set a listener to be invoked when the positive button of the dialog is pressed，这个Listener是监听button被点击事件。我们的目的是让AlertDialog 在点击确定或者取消时不消失，那么屏蔽此Listener即可。

解决方法：

继承AlertDialog自定义自己的AlertDialog，重写以上四个方法：(把这四个方法拷贝过来，都不要这两句：
P.mPositiveButtonListener = listener;
P.mNegativeButtonListener = listener;）

此外还有不常用的这个按钮，如法炮制。
public Builder setNeutralButton(int textId, final OnClickListener listener)
public Builder setNeutralButton(CharSequence text, final OnClickListener listener)
