如何在对话框打开时为活动设置可取消的false？

Question

嗨,我做了一个活动,我打开一个活动作为另一个活动的对话框弹出窗口,所以我问.这是我的主题的问题,

 <item `name="android:windowCloseOnTouchOutside">@bool/config_closeDialogWhenTouchOutside</item>`

但我不知道我应该改变什么值,"windowCloseOnTouchOutside"以便我可以做我的活动对话框设置取消错误..？我的主题代码如下:

您可以非常轻松地在Java编码中实现这一点.如果你有一个Activity(即使它看起来像一个Dialog),那么你应该这样做

this.setFinishOnTouchOutside(false);

如果您使用过Dialog类,则应该调用

dialog.setFinishOnTouchOutside(false) 

如果要在单击后台活动时阻止关闭它.
