if you want your activity to be in background add this line in the oncreate of activity
如果您希望您的活动处于后台，请在活动的 oncreate 中添加此行
moveTaskToBack(true);

You can use this line in your onCreate()method:
您可以在您的onCreate()方法中使用这一行：
moveTaskToBack(true);

You don't want to start an Activityin the background. There are better ways to do what you want. You can have your Activityregister to receive the broadcast Intent, for example. It will get the call to onReceive()even if it is in the background. You can determine if your Activityis in the background by setting a variable to truein onPause()and to falsein onResume(). Then in onReceive(), if the variable is trueyou are in the background.
您不想Activity在后台启动。有更好的方法来做你想做的事。例如，您可以让您的Activity寄存器接收广播Intent。onReceive()即使它在后台，它也会得到调用。您可以Activity通过将变量设置为trueinonPause()和falsein来确定您是否在后台onResume()。然后在onReceive()，如果变量是true你在后台。
