使用我的应用程序后，我正在按 Home 以在后台运行应用程序。如果我立即再次打开该应用程序，它会打开该应用程序。

这只发生在我的 google nexus 中。我在 LG optimus 和 google tab2 中测试了该应用程序，也在这些设备应用程序上正常工作。

我的活动布局是

我可能是错的，但似乎当您从“最近”启动该应用程序时，它会调用一个视图，该视图由于Activity在后台时间过长而不再膨胀，因此被杀死。

这发生在其他设备上而不是在 Google Nexus 上这一事实并不能说明太多——当 Android 终止后台进程时可能是任意的，具体取决于您的内存使用情况和其他因素。如文档中所述：

Android 系统尝试尽可能长时间地保留应用程序进程，但最终需要在内存不足时删除旧进程。如活动生命周期中所述，关于删除哪个进程的决定与用户与其交互的状态密切相关。通常，根据其中运行的活动，流程可以处于四种状态，此处按重要性顺序列出。系统会在杀死更重要的进程（第一个）之前杀死不太重要的进程（最后一个）。

您是否尝试在方法中保存您的应用程序的状态，或者在、、或onStop()中的任何一个中重新填充上述日志中描述的组件？这完全取决于您将使用哪种方法。供参考：http: //developer.android.com/reference/android/app/Activity.html#ActivityLifecycleonCreate()onStart()onResume()onRestart()
