这是lifecycle- 当按下Home键后的任何应用程序的活动转到后台活动,这是不能随意破坏 - 操作系统破坏在后台活动在运行时缺少可用的RAM,所以当Home按钮被按下时,活动进入onPause() - > onStop(),然后取决于操作系统的仁慈。
这可能发生在任何运行Android操作系统的设备上,该设备在任何给定的时间都会运行在内存不足的情况下,而不仅仅是Galaxy S3。
来处理这个问题的方法是在你的活动的onSaveInstanceState使用:
@Override
protected void onSaveInstanceState(Bundle outState) {
// Put all important data you have into the outState before calling
// super.
super.onSaveInstanceState(outState);
}
@Override
protected void onRestoreInstanceState(Bundle state) {
super.onRestoreInstanceState(state);
// Here you will receive the bundle you put in onSaveInstanceState
// and you can take it from the state bundle and put it in place.
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Here you need to check if you have data, if
// onSaveInstanceState was called and you put data in that
// function, data should be available here, and put it back into
// place.
}
