如何对像whatsapp这样的android通知进行分组? [英] How to group android notifications like whatsapp?

问题描述

我不知道如何将两个或多个通知组合成一个，并显示您有两条新消息"之类的消息.

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

推荐答案

以下代码中需要注意的步骤.

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.

使用以下代码创建通知并将其分组.在按钮单击中包含该功能.

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());
        }
}

对于单独的通知，分配不同的 NOTIFICATION_ID..

For separate notifications assign different NOTIFICATION_IDs..
