为什么AlertDialog.Builder没有setOnDismissListener或setOnShowListener方法呢？ [英] Why does AlertDialog.Builder not have setOnDismissListener or setOnShowListener methods?

问题描述

我想用AlertDialog.Builder的流体界面，但是当我去加入我的DismissListener和ShowListener点我一定要打破，并将其添加到（）在Builder对话框对象我做我的创建后。有谁知道为什么他们不是在那里？我不能延长，因为私有P成员的...这是不是世界或任何月底，我只是好奇，为什么它不存在。

I want to use the fluid interface of AlertDialog.Builder but when I get to the point of adding my DismissListener and ShowListener I have to break out and add it to the dialog object after I do my create() on the builder. Does anyone know why they're not on there? I can't extend it because of the private P member... It's not the end of the world or anything, I'm just curious why it's not there.

推荐答案

你尝试过这种方法。

AlertDialog dlg = builder.create();
lg.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(final DialogInterface dialog) {
//Do some work
}
});
return dlg;
