我已经阅读了SO问题中的说明和示例,但仍然无法实现简单的BroadcastReceiver,它根本没有收到任何东西,有人可以就以下代码提供一些建议吗?

我的活动:

public class Receiver1Activity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        IntentFilter filter = new IntentFilter(MyService.MY_ACTION);
        registerReceiver(new MyReceiver(), filter);
        Intent intent = new Intent();
        startService(intent);
    }
}

我的接收者:

public class MyReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context arg0, Intent arg1) {
        Log.i("MyReceiver", "onreceive");       
    }
}

我的服务,发送广播:

public class MyService extends Service {

    public static final String MY_ACTION = "com.receiver1.myaction";
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Intent intent2 = new Intent(MY_ACTION);
        sendBroadcast(intent2);
        return START_NOT_STICKY;
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }

}

我的清单文件:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.receiver1"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="10" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".Receiver1Activity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <service android:name=".MyService"></service>
</application>

</manifest>

您确定自己的服务即将开始吗?看起来你只是创建一个空白的意图并调用startService()。

您的broadcastReceiver似乎是正确的。

您需要register your receiver in your AndroidManifest.xml。在您这样做之前,Android操作系统将无法找到您的BroadcastReceiver。
