我正在编写一个应用程序，我必须解决这个问题......在任何活动中，当点击主页按钮时手机会重新启动，我不希望这种情况发生。
我知道单击主页按钮会将应用程序带到后台，并且从 Android 生命周期中我会说调用了 OnPause。也许我可以使用这个 OnPause() 方法解决问题，但我不知道该怎么做。
我在每个活动中都包含了以下日志：
@Override
protected void onPause()
{
Log.d(tag, "MYonPause is called");
super.onPause();
}
@Override
protected void onStop()
{
Log.d(tag, "MYonStop is called");
super.onStop();
}
@Override
protected void onDestroy()
{
Log.d(tag, "MYonDestroy is called");
super.onDestroy();
}
这是我点击主页按钮后的 LogCat：
