Imagine I have a Dialog with a OK button on it, and want to close it by OK button, but I cant do that!
想象一下，我有一个带有 OK 按钮的对话框，想通过 OK 按钮关闭它，但我不能这样做！
I googled and found nothing useful, and almost all of them for closing AlertDialog not a Dialog.
我用谷歌搜索并没有发现任何有用的东西，几乎所有这些都是为了关闭 AlertDialog 而不是 Dialog。

Only this line will close it. :-)

Implement it in the onClickListener.
在 onClickListener 中实现它。

You can use the methods cancel()or dismiss(). The method cancel()essentially the same as calling dismiss(), but it will also call your DialogInterface.OnCancelListener(if registered).
您可以使用 方法cancel()或dismiss()。该方法cancel()本质上与调用dismiss() 相同，但它也会调用您的DialogInterface.OnCancelListener（如果已注册）。

Alternative to the dismiss();option, if you have your dialog as a separate Activity(s.a. DialogActivity), another way to close it is to call:
作为该dismiss();选项的替代方案，如果您将对话框作为单独的Activity(sa DialogActivity)，另一种关闭它的方法是调用：
finish();
Call this method inside the OnClickListenerclass' onClick()method.
在OnClickListener类的onClick()方法中调用此方法。
This will call the onPause(), onStop()and onDestroy()methods consequently and kill the current activity - same as Backbutton.
这将因此调用onPause(),onStop()和onDestroy()方法并终止当前活动 - 与后退按钮相同。
