我有一个复选框的活动：如果chekbox的勾选，那么停止该服务。这是我的活动code的一个片段：

I have an activity with a checkbox: if the chekbox is unchecked then stop the service. this is a snippet of my activity code:

    Intent serviceIntent = new Intent();
    serviceIntent.setAction("com.android.savebattery.SaveBatteryService");

    if (*unchecked*){
        serviceIntent.putExtra("user_stop", true);
        stopService(serviceIntent);

当我停止服务，我传递一个参数user_stop在那一直是用户停止它，而不是系统（低内存）的服务的话。

when I stop the service I pass a parameter "user_stop" to say at the service that has been a user to stop it and not the system (for low memory).

现在我要读我的服务空白的onDestroy变量user_stop：

now I have to read the variable "user_stop" in void onDestroy of my service:

public void onDestroy() {
super.onDestroy();

Intent recievedIntent = getIntent(); 
boolean userStop= recievedIntent.getBooleanExtra("user_stop");

    if (userStop) {
       *** notification code ****

，但它不工作！在我的onDestroy不能使用getIntent（）！

but it doesn't work! I can't use getIntent() in onDestroy!

任何建议？

感谢

推荐答案

我认为这样做的两种方式：

I see two ways of doing this:

第一种方法是一种简单而直接的方式。但它不是很灵活。基本上，你做的：

The first approach is an easy and straightforward way. But it is not very flexible. Basically you do:

另一种方法是一个更好的办法，但需要更多的code。

The other approach is a better way but requires more code.

final public static string USER_STOP_SERVICE_REQUEST = "USER_STOP_SERVICE".

乙。创建一个内部类BroadcastReceiver的类：

b. Create an inner class BroadcastReceiver class:

public class UserStopServiceReceiver extends BroadcastReceiver  
{  
    @Override  
    public void onReceive(Context context, Intent intent)  
    {  
        //code that handles user specific way of stopping service   
    }  
}

℃。注册该接收机的onCreate或OnStart方法：

c. Register this receiver in onCreate or onStart method:

registerReceiver(new UserStopServiceReceiver(),  newIntentFilter(USER_STOP_SERVICE_REQUEST));

Ð。从你要停止你的服务的任何地方：

d. From any place you want to stop your service:

context.sendBroadcast(new Intent(USER_STOP_SERVICE_REQUEST));

请注意，您可以通过意向使用这种方法传递任何自定义的参数。

Note that you can pass any custom arguments through Intent using this approach.
