当我锁定手机并在一个活动中解锁时总是调用onCreate，我遇到了问题。也许有人可以帮助我？这是我的onCreate，也许我做错了什么，叫做onCreate。在我的应用程序中创建是第一次在应用程序和我解锁手机时调用，但当我mminimalize我的应用程序并打开一个应用程序我的应用程序调用onResume

答案 0 :(得分：0)
我更改了我的清单：我添加了这个：android:configChanges="orientation|keyboardHidden|screenSize"
因为：
要声明您的活动处理配置更改，请编辑清单文件中的相应元素，以包含android：configChanges属性，其中包含表示要处理的配置的值。 android：configChanges属性的文档中列出了可能的值（最常用的值是“orientation”以防止在屏幕方向更改时重新启动，“keyboardHidden”以防止在键盘可用性更改时重新启动）。您可以通过使用管道分隔属性来声明属性中的多个配置值字符。
