如何分组android通知，如whatsapp？ [英] How to group android notifications like whatsapp?

问题描述

我不知道如何将两个或更多的通知分组到一个，并显示一条消息，比如您有两条新消息。

解决方案

  NotificationCompat.Builder：包含UI规范和操作信息
 NotificationCompat.Builder.build（）：用于创建通知（返回Notification对象）
 Notification.InboxStyle：用于将通知分组属于同一个ID 
 NotificationManager.notify（）：发布通知。 
  

使用下面的代码创建通知并对其进行分组。

  private final int NOTIFICATION_ID = 237; 
 private static int value = 0; 
 Notification.InboxStyle inboxStyle = new Notification.InboxStyle（）; 
位图位图= BitmapFactory.decodeResource（getResources（），R.drawable.push_notify_icon）; 
 public void buttonClicked（View v）
 {
 value ++; 
 if（v.getId（）== R.id.btnCreateNotify）{
 NotificationManager nManager =（NotificationManager）getSystemService（NOTIFICATION_SERVICE）; 
 Notification.Builder builder = new Notification.Builder（this）; 
 builder.setContentTitle（Lanes）; 
 builder.setContentText（来自泳道的通知+值）; 
 builder.setSmallIcon（R.drawable.ic_launcher）; 
 builder.setLargeIcon（bitmap）; 
 builder.setAutoCancel（true）; 
 inboxStyle.setBigContentTitle（输入内容文本）; 
 inboxStyle.addLine（hi events+ value）; 
 builder.setStyle（inboxStyle）; 
 nManager.notify（App Name，NOTIFICATION_ID，builder.build（））; 
 
 
 $ / code> 

对于单独的通知分配不同的NOTIFICATION_ID ..

I don´t know how to group two or more notifications into only one and show a message like "You have two new messages".

解决方案

Steps to be taken care from the below code.

NotificationCompat.Builder:contains the UI specification and action information
NotificationCompat.Builder.build() :used to create notification (Which returns Notification object)
Notification.InboxStyle: used to group the notifications belongs to same ID
NotificationManager.notify():to issue the notification.

Use the below code to create notification and group it. Include the function in a button click.

private final int NOTIFICATION_ID = 237;
private static int value = 0;
Notification.InboxStyle inboxStyle = new Notification.InboxStyle();
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.push_notify_icon);
public void buttonClicked(View v)
{
        value ++;
        if(v.getId() == R.id.btnCreateNotify){
            NotificationManager nManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            Notification.Builder builder = new Notification.Builder(this);            
            builder.setContentTitle("Lanes");
            builder.setContentText("Notification from Lanes"+value);
            builder.setSmallIcon(R.drawable.ic_launcher);
            builder.setLargeIcon(bitmap);
            builder.setAutoCancel(true);
            inboxStyle.setBigContentTitle("Enter Content Text");
            inboxStyle.addLine("hi events "+value);
            builder.setStyle(inboxStyle);
            nManager.notify("App Name",NOTIFICATION_ID,builder.build());
        }
}

For separate notifications assign different NOTIFICATION_IDs..
