Notification是Android中用于消息通知的机制,具体形式是,有消息来后,会在Android手机顶部的状态栏中显示提示信息,如,各自APP的消息通知。
使用Notification基本有以下几个步骤
1 获取NotificationManager
NotificationManager notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
该对象用来后面发送消息
2 创建NotificationCompat.Builder
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
该对象主要是对消息的外观进行封装
3 对Builder设置相关的Notification属性,必要属性如下:
builder.setContentTitle("标题");
builder.setContentText("内容:Android很好玩");
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setContentIntent(pendingIntent);
4 使用Builder创建通知
Notification notification = builder.build();
5 发送通知
notificationManager.notify(199, notification);
如此,一个基本通知消息就发送出去了。

package com.example.xxh.notifymsg;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.app.NotificationCompat;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = (Button)findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
sendSimpleNotification();
}
});
}
private void sendSimpleNotification()
{
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel: 10086"));
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationManager notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentTitle("标题");
builder.setContentText("内容:Android很好玩");
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setContentIntent(pendingIntent);
Notification notification = builder.build();
notification.flags = Notification.FLAG_SHOW_LIGHTS | Notification.FLAG_INSISTENT | Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(199, notification);
}
}
