如何处理AlertDialog关闭事件? [英] How to handle AlertDialog close event?

问题描述

使用外部触摸事件关闭AlertDialog时是否存在回调?我启用了"setCanceledOnTouchOutside(true)".我想使用外部触摸事件关闭AlertDialog后，设置特定视图的可见性.有什么想法吗?

如果有帮助，我正在Fragment内使用AlertDialog.Builder().

解决方案

一个而是android.com/reference/android/app/AlertDialog.Builder.html#setOnCancelListener%28android.content.DialogInterface.OnCancelListener%29"rel =" nofollow> OnCancelListener .

Is there a callback when an AlertDialog is closed using the touch outside event? I have this enabled "setCanceledOnTouchOutside(true)". I want to set a visibility of a specific view once the AlertDialog is closed using the touch outside event. Any ideas?

I am using the AlertDialog.Builder() inside a Fragment if that helps.

解决方案

an OnDismissListener seems most appropriate, but it requires a relatively high API level, so you might need to stick with an OnCancelListener instead.
