Android：单击主页按钮时避免手机重启

时间：2012-07-17 08:39:24

标签： android restart onpause android-homebutton

我正在编写应用程序，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，而Android Lifecycle会调用OnPause。也许我可以使用这个OnPause（）方法解决问题，但我不确切知道该做什么。

我在每项活动中都包含以下日志：

@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();
}

点击主页按钮后，这是我的LogCat：

显然，当按下“HOME”按钮时，将调用活动的onStop()方法。您可以使用以下代码覆盖（监视）它：

@Override

    super.onStop();
    Log.d(tag, "MYonStop is called");
    // insert here your instructions
}
