BroadcastReceiver的获得ServiceState信息 [英] Broadcastreceiver to obtain ServiceState information

问题描述

有谁知道的方式来获得手机服务状态（IN_SERVICE，OUT_OF_SERVICE，EMERGENCY_ONLY，POWER_OFF）的机器人。

Does anyone know of a way to obtain the phone service state (IN_SERVICE, OUT_OF_SERVICE, EMERGENCY_ONLY, POWER_OFF) in android.

我希望会有一个broadcastreciever，以找出发生的变化，但我无法找到任何东西。我知道有一个监听器，但我不知道我怎么会用，从我的应用程序，因为它是用WakefulIntentService（由thecommonsguy）的服务运行。

I was hoping there would be a broadcastreciever to identify the changes, but I can't find anything. I know there's a listener but I'm not sure how I would use that from my app as it runs as a service using a WakefulIntentService (by thecommonsguy).

使用类似的电量（即BATTERY_LOW，BATTERY_OKAY）这是很容易的，但我就是不能制定出一个类似的东西的电话服务的变化。

With something like battery level (ie BATTERY_LOW, BATTERY_OKAY) it's quite easy, but I just can't work out a similar things for phone service changes.

推荐答案

注册一个接收器

public static final String ACTION_SERVICE_STATE_CHANGED = "android.intent.action.SERVICE_STATE";

当你打算在你的接收器只需使用下面的小黑客从Android源

When you get intent on your receiver just use below little hack from android source

public void onReceive(Context context, Intent intent) {
    int state = intent.getExtras().getInt("state");
    if(state == ServiceState.STATE_IN_SERVICE)
    {
        //Do whatever you want
    }
    }

检查服务状态类的源 <一href="http://grep$c$c.com/file/repository.grep$c$c.com/java/ext/com.google.android/android/1.5_r4/android/telephony/ServiceState.java#ServiceState.setFromNotifierBundle%28android.os.Bundle%29" rel="nofollow">http://grep$c$c.com/file/repository.grep$c$c.com/java/ext/com.google.android/android/1.5_r4/android/telephony/ServiceState.java#ServiceState.setFromNotifierBundle%28android.os.Bundle%29

check source of service state class http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/1.5_r4/android/telephony/ServiceState.java#ServiceState.setFromNotifierBundle%28android.os.Bundle%29
