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)
