Question

I am using start activity for result to help users of my application filter some information out. Once the information is filtered i add it to the intent and then call finish. The works perfectly except for when the users have rotated the device when they are performing the filtering. This causes the first activity to create all over again and since this happens my filtering options are wiped out (They finish before onCreate is over so the UI is cleared). Any ideas on a way to handle this? Thanks

Answer 1

有三个选项可以做到这一点

onSaveInstance State () // / 但通常可以处理少量数据
on remainen not condifiation Instance () 并获得Lastnest Confinigiation Instance () //Pedit
android: configCHanges=“ 方向” in AndroidManifest.xml 中“ 方向” : configCHanges=“ 方向“ 键盘 Hidden” in AndroidManifest.xml

/ 这将不允许活动重新启动, 当您想要保存的数据不大时使用此选项。对于 api 13+ 使用此 android: configCHanges=" 方向\\ creenSize"
