在Android中静态注册自定义广播接收器的正确方法是什么？ [英] What is the right way of static registration of custom Broadcast receiver in Android?

问题描述

我要静态注册接收者，而不是动态注册。
对于动态注册，它很好用，我正在使用它：

Instead of dynamic registration, I want to statically register my receiver. For dynamic registration, it works well, I was using this :

..
static private IntentFilter GPSActionFilter;
..
GPSActionFilter = new IntentFilter("GGPS Service");
context.registerReceiver(GPSActionReceiver, GPSActionFilter);
..
static private BroadcastReceiver GPSActionReceiver = new BroadcastReceiver(){  
    public void onReceive(Context context, Intent intent) {  ..}

对于静态注册，调试器从不使用onReceive函数，我使用的是：

在AndoridManifest中：

In AndoridManifest :

<receiver android:name="LocationListener$GPSActionReceiver" >   
    <intent-filter>
        <action android:name="LocationListener.ACTION_GPS_SERVICE" />
    </intent-filter>
</receiver>

在代码中：

public class LocationListener extends BroadcastReceiver
{
    public static IntentFilter GPSActionFilter;
    public static final String ACTION_GPS_SERVICE = "com.example.LocationListener.GPSActionFilter";
    public static BroadcastReceiver GPSActionReceiver;
    public void onReceive(final Context context, final Intent intent)
    {..}
}

推荐答案

在清单中声明意图过滤器动作时，android：name必须是字符串文字，并且不能从类访问String。另外，我建议您在意图操作之前添加完全限定的程序包名称，即：

When declaring an intent-filter action in the manifest, the android:name must be a string literal and can not access Strings from classes. Also, I recommend you prepend your fully qualified package name to the intent action ie:

public static final String GPS_SERVICE = "com.example.LocationListener.ACTION_GPS_SERVICE"

然后更改

<action android:name="LocationListener.GPS_SERVICE" />

到

<action android:name="com.example.LocationListener.ACTION_GPS_SERVICE" />
