我在Android 2.3.7和我想要当用户开启GPS写一个BroadcastReceiver将调用/关（即：通过点击在选项使用GPS卫星

I'm on Android 2.3.7 and I'm trying to write a BroadcastReceiver that will get called when the user turns GPS on/off (ie: by tapping on the "use GPS satellites" in the options.

什么我迄今所做的是这样的：

What I've done so far is this:

1）创建以下的BroadcastReceiver：

1) Created the following broadcastReceiver:

public class GPSStatusBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        Toast.makeText(arg0, "Broadcast received!", Toast.LENGTH_SHORT).show();

    }
}

2）添加到了Android清单，在标签中：

2)Added this to the android manifest, inside the tags:

<receiver android:name=".GPSStatusBroadcastReceiver"> 
    <intent-filter> 
        <action android:name="android.location.PROVIDERS_CHANGED" /> 
    </intent-filter> 
</receiver>

现在与此的问题是，它似乎不可靠。当我打开GPS上/ FF的的onReceive（）方法只运行有时（我说1超时3）其他时候它不会被调用。

Now the problem with this is that it appears not to be reliable. When I turn GPS on/ff the onReceive() method only runs sometimes (I'd say 1 time out 3) the other times it doesn't get called.

我想知道是否有检测时，GPS关闭的可靠方法/上。

I want to know if there is a reliable way to detect when the GPS is turned off/on.

如果没有这将是很好时，没有应用程序正在使用GPS anymoer必须至少在通知（即：当GPS图标状态栏，从消失，说明没有人主动定位）。

If there isn't it would be nice to be notified at least when no app is using the GPS anymoer (ie: when the gps icon disappears from statusbar, indicating no one is actively locating).

编辑：澄清：我不希望我的应用程序运行时做到这一点。我只是whatn我的应用程序时，打开GPS来启动/关闭，做它的东西，然后终止，我并不想订阅LocationsUpdates ...

Clarification: I don't want to do this while my app is running. I just whatn my app to be started when gps is turned on/off, do its thing and then terminate, I don't want to subscribe to LocationsUpdates...

推荐答案

答案是LocationManager.PROVIDERS_CHANGED_ACTION\"

公共静态最后弦乐PROVIDERS_CHANGED_ACTION

public static final String PROVIDERS_CHANGED_ACTION

在API级别9 广播意图操作时配置的位置提供改变。用于与isProviderEnabled（字符串）使用。如果你正在与LOCATION_MODE API进行交互，使用MODE_CHANGED_ACTION来代替。

Added in API level 9 Broadcast intent action when the configured location providers change. For use with isProviderEnabled(String). If you're interacting with the LOCATION_MODE API, use MODE_CHANGED_ACTION instead.

恒值：android.location.PROVIDERS_CHANGED

Constant Value: "android.location.PROVIDERS_CHANGED"
