IntentService onHandleEvent() 未启动

Question

我希望在单击通知操作按钮时执行某些方法。我在这个网站上搜索过，但似乎一切正常，我的 IntentService 没有被调用。

我的操作按钮意图

    Intent off = new Intent();
    off.setAction("action");
    off.putExtra("test", "off");
    PendingIntent pOff = PendingIntent.getService(context, 22, off, 0);

通知生成器

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
            .setSmallIcon(/**/)
            .setContentTitle(/**/)
            .setContentText(/**/)
            .addAction(/**/, "Off", pOff)
            .setContentIntent(pendingIntent)
            .setDefaults(Notification.DEFAULT_SOUND)
            .setAutoCancel(true);

意向服务Class

public class NotificationServiceClass extends IntentService {

public NotificationServiceClass(String name) {
    super(name);
}

public NotificationServiceClass () {
    super("NotificationServiceClass");
}

@Override
protected void onHandleIntent(Intent intent) {
    Log.i("test", "onHandle");
    if (intent.getAction().equals("action")) {
        Log.i("test", "action");
        Bundle bundle = intent.getExtras();
        if (bundle != null) {
            Log.i("test", "onHandleBundleNotNull");
            if (bundle.containsKey("test")) {
                Log.i("test", bundle.getString("test"));
            }
        }
    }
}
}

XML 服务声明 class

    <service
        android:name=".Manager.NotificationServiceClass"
        android:exported="false">
    </service>

Answer 1

根据 Intents and Intent Filters training，您构建的 Intent 是一个隐式 Intent：

Implicit intents do not name a specific component, but instead declare a general action to perform, which allows a component from another app to handle it. For example, if you want to show the user a location on a map, you can use an implicit intent to request that another capable app show a specified location on a map.

您真正想要的是一个明确的意图：根据同一页面上的注释指定要以名称开头的组件：

Note: When starting a Service, you should always specify the component name. Otherwise, you cannot be certain what service will respond to the intent, and the user cannot see which service starts.

构建 Intent 时，您应该使用

// Note how you explicitly name the class to use
Intent off = new Intent(context, NotificationServiceClass.class);
off.setAction("action");
off.putExtra("test", "off");
PendingIntent pOff = PendingIntent.getService(context, 22, off, 0);

Answer 2

在查看您的代码时，我没有看到您告诉 PendingIntent 什么 class 用于您的服务。

您应该添加：

off.setClass(this, NotificationServiceClass.class);

否则PendingIntent无事可做。
