【问题描述】：

我制作了custom notification，其中有一个按钮，我想执行两个不同的functionalities on notification and button click。我查看了许多链接，但找不到添加按钮侦听器的方法。

谁能帮忙。这是我的代码。非常感谢。

 private void startNotification() 
    Intent intent;
    PendingIntent pIntent;
    RemoteViews remoteViews = new RemoteViews(getPackageName(),
            R.layout.mynotification);

    Context context = getApplicationContext();
    NotificationCompat.Builder builder = new NotificationCompat.Builder(
            this).setSmallIcon(R.drawable.ic_launcher).setContent(
            remoteViews);

    if (hasFlash) 
        intent = new Intent(context, FlashLight.class);
        pIntent = PendingIntent.getActivity(context, 1, intent, 0);
     else 
        intent = new Intent(context, BlankWhiteActivity.class);
        pIntent = PendingIntent.getActivity(context, 1, intent, 0);
    
    builder.setContentIntent(pIntent);
    NotificationManager mNotificationManager = (NotificationManager)      getSystemService(Context.NOTIFICATION_SERVICE);

    Notification notif = builder.setContentTitle("Flashlight")
            .setContentText("Lighten your world!!!").build();
    mNotificationManager.notify(1, notif);

    remoteViews.setOnClickPendingIntent(R.id.closeOnFlash, pIntent);

我在setOnClickPendingIntent 中传递了按钮 ID (closeOnFlash)，不知道为什么它不起作用。

这是我的xml：

<?xml version="1.0" encoding="UTF-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_
 android:layout_
 android:gravity="center"
 android:orientation="horizontal"
 android:weightSum="100" >

<ImageView
    android:id="@+id/notifiation_image"
    android:layout_
    android:layout_
    android:layout_weight="30"
    android:contentDescription="@string/appImage"
    android:src="@drawable/ic_launcher" />

<TextView
    android:id="@+id/appName"
    android:layout_
    android:layout_
    android:layout_weight="50"
    android:gravity="center"
    android:text="@string/flashLightOn"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<Button
    android:id="@+id/closeOnFlash"
    android:layout_
    android:layout_
    android:layout_weight="20"
    android:text="@string/close" />

这个帖子应该回答你想要做什么：***.com/questions/12438209/…

好的，非常感谢，我会看看。

实际上第二个对我的 HTC 感觉非常有效，还没有检查兼容性问题。

【参考方案1】：

开始通知为：

private void startNotification()
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager notificationManager = 
            (NotificationManager) getSystemService(ns);

    Notification notification = new Notification(R.drawable.ic_launcher, null, 
            System.currentTimeMillis());

    RemoteViews notificationView = new RemoteViews(getPackageName(),
            R.layout.mynotification);

    //the intent that is started when the notification is clicked (works)
    Intent notificationIntent = new Intent(this, FlashLight.class);
    PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this, 0, 
            notificationIntent, 0);

    notification.contentView = notificationView;
    notification.contentIntent = pendingNotificationIntent;
    notification.flags |= Notification.FLAG_NO_CLEAR;

    //this is the intent that is supposed to be called when the 
    //button is clicked
    Intent switchIntent = new Intent(this, switchButtonListener.class);
    PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0, 
            switchIntent, 0);

    notificationView.setOnClickPendingIntent(R.id.closeOnFlash, 
            pendingSwitchIntent);

    notificationManager.notify(1, notification);



public static class switchButtonListener extends BroadcastReceiver 
    @Override
    public void onReceive(Context context, Intent intent) 
        Log.d("Here", "I am here");
        FlashOnOff flashLight;
        flashLight = new FlashOnOff();
        flashLight.flashLightOff();
        flashLight.releaseCamera();         
    

使用的xml：

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_
android:layout_
android:gravity="center"
android:orientation="horizontal"
android:weightSum="100" >

<ImageView
    android:id="@+id/notifiation_image"
    android:layout_
    android:layout_
    android:layout_weight="30"
    android:contentDescription="@string/appImage"
    android:src="@drawable/ic_launcher" />

<TextView
    android:id="@+id/appName"
    android:layout_
    android:layout_
    android:layout_weight="50"
    android:gravity="center"
    android:text="@string/flashLightOn"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<Button
    android:id="@+id/closeOnFlash"
    android:layout_
    android:layout_
    android:layout_weight="20"
    android:text="@string/close" />

在应用标签下的清单中：

<receiver android:name="FlashLight$switchButtonListener" />

@PoojaShah 乐于提供帮助 :)

Manifest 中的声明是如何工作的？ FlashLight 您的课程是否包含 swiftButtonListener ？是应用名称吗？

这真是个好主意！感谢分享！

@ShaikMDAshiq 是的，它是包含接收器的类，您也可以使用类的完全分类名称

这是否被视为必须在 Manifest 中声明的全局广播？如果不是，为什么不能用作LocalBroadcast？
