I am creating an Android app in which I'm drawing a view on a canvas. When the device's orientation changes, the activity restarts. I don't want it to.
如何避免在方向改变时重新启动活动?
How can I avoid restarting the activity when the orientation changes?
有多种方法可以做到,但是给定 这里,使用
There are various ways to do it, but as given here, using
android:configChanges="keyboardHidden|orientation|screenSize"
允许您监听配置更改.然后,您通过覆盖 onConfigurationChanged
并调用 setContentView
来响应这些更改.
allows you to listen for the config changes. You then respond to these changes by overriding onConfigurationChanged
and calling setContentView
.
这就是我一直这样做的方式,但我很想知道其他人的想法.
This is the way I've been doing it, but I'd be interested to know other people's thoughts.
