Android通知按钮（的addAction）敬酒消息按下

分类: 技术问答 • 2022-06-17 14:34:44
问题描述：

当我想上一个通知（归档）时，一些关于它的一个点击喜欢的按钮添加一个动作，它显示了一个敬酒的消息，下面是一个示例图像：Android通知按钮（的addAction）敬酒消息按下

Image 这是我PendingIntent行代码：

var contentIntent = PendingIntent.GetActivity(context, 0, resultIntent, PendingIntentFlags.CancelCurrent);

这是我的通知卜ilder代码：

var builder = new NotificationCompat.Builder(context) 
      .SetContentIntent(contentIntent).SetSmallIcon(Resource.Drawable.ic_launcher) 
                .SetContentTitle(title) 
      .SetStyle(style).SetWhen(Java.Lang.JavaSystem.CurrentTimeMillis()) 
                .AddAction(Resource.Drawable.tick_notify, "ARCHIVE", contentIntent) 
      .AddAction(Resource.Drawable.cancel_notify, "REPLY", pIntent) 
      .SetAutoCancel(true); 
       //check bewlow 
       builder.SetDefaults((int)(NotificationDefaults.Sound | NotificationDefaults.Vibrate));

所以一般我想打一个按钮进行通知，而不是推出一个活动等

帮我在这的Xamarin.android是新请。

您需要一个广播接收器才能够在您点击该动作时显示一个Toast。对于每个动作，您需要一个意图激发广播接收器意图。在这里它会是什么样子的例子：

=========广播接收器类==========

[BroadcastReceiver] 
public class CustomActionReceiver : BroadcastReceiver 
{ 
    public override void OnReceive(Context context, Intent intent) 
    { 
     //Show toast here 
     Toast.MakeText(context, intent.Action, ToastLength.Short).Show(); 
     var extras = intent.Extras; 

     if (extras != null && !extras.IsEmpty) 
     { 
      NotificationManager manager = context.GetSystemService(Context.NotificationService) as NotificationManager; 
      var notificationId = extras.GetInt("NotificationIdKey", -1); 
      if (notificationId != -1) 
      { 
      manager.Cancel(notificationId); 
      } 
     } 


    } 
}

======= ==========建立通知============

  customReceiver = new CustomActionReceiver(); 

     //Create intent for action 1 (ARCHIVE) 
     var actionIntent1 = new Intent(); 
     actionIntent1.SetAction("ARCHIVE"); 
     var pIntent1 = PendingIntent.GetBroadcast(context, 0, actionIntent1, PendingIntentFlags.CancelCurrent); 

     //Create intent for action 2 (REPLY) 
     var actionIntent2 = new Intent(); 
     actionIntent2.SetAction("REPLY"); 
     var pIntent2 = PendingIntent.GetBroadcast(context, 0, actionIntent2, PendingIntentFlags.CancelCurrent); 


     Intent resultIntent = context.PackageManager.GetLaunchIntentForPackage(context.PackageName); 
     var contentIntent = PendingIntent.GetActivity(context, 0, resultIntent, PendingIntentFlags.CancelCurrent); 

     var builder = new NotificationCompat.Builder(context) 
     .SetContentIntent(contentIntent).SetSmallIcon(Resource.Drawable.ic_launcher) 
     .SetContentTitle(title) 
     .SetStyle(style).SetWhen(Java.Lang.JavaSystem.CurrentTimeMillis()) 
     .AddAction(Resource.Drawable.tick_notify, "ARCHIVE", pIntent1) 
     .AddAction(Resource.Drawable.cancel_notify, "REPLY", pIntent2) 
     .SetAutoCancel(true); 

     builder.SetDefaults((int)(NotificationDefaults.Sound | NotificationDefaults.Vibrate)); 

     //Add intent filters for each action and register them on a broadcast receiver 
     var intentFilter = new IntentFilter(); 
     intentFilter.AddAction("ARCHIVE"); 
     intentFilter.AddAction("REPLY"); 

     context.RegisterReceiver(customReceiver, intentFilter); 

     NotificationManager notificationManager = (NotificationManager)context.GetSystemService(Context.NotificationService); 
     notificationManager.Notify(0, builder.Build());

我试图实现你的答案@Rendy，但我得到一个错误，所以请我的完整的代码我已经更新我的职务 –

您不能在另一个广播接收机内注册广播接收机意图。试试这个：
