【android】Notification的使用

 

package com.noti.activity;

 

import android.app.Activity;

import android.app.Notification;

import android.app.NotificationManager;

import android.app.PendingIntent;

import android.content.Context;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.RemoteViews;

 

public class Main extends Activity {

    /** Called when the activity is first created. */

private Button btn;//使用系统的notification布局

private Button btn1;//使用自定义布局

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        btn = (Button) findViewById(R.id.btn);

        btn1 = (Button) findViewById(R.id.btn1);

        btn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

showNotification();

}

});

     btn1.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

showMyNotification();

}

});

    }

    public void showNotification(){

  获得系统的NotificationManager对象

    NotificationManager  notificationManager = (NotificationManager)       getSystemService(Context.NOTIFICATION_SERVICE);

 //实例化一个的notification

Notification notification = new Notification(R.drawable.image1, "notice", System.currentTimeMillis());

Intent  intent =  new Intent(Main.this,OtherActivity.class);//点击这个notification触发的Intent

PendingIntent pendingIntent =  PendingIntent.getActivity(this, 0, intent, 1);

notification.setLatestEventInfo(this, "title","a message", pendingIntent);//显示notification的布局和触发器

notificationManager.notify(R.id.btn, notification);//发出通知，根据Id判断是否为新的通知

    }

 

    public void showMyNotification(){

    NotificationManager  notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

Notification notification = new Notification(R.drawable.icon, "notice", System.currentTimeMillis());

//要实现自定义布局，首先自己定义一个 布局文件notification.xml,如放一个ImageView 和 TextView，用这个布局文件生成 //RemoteViews的实例

RemoteViews contentview = new RemoteViews(getPackageName(), R.layout.notification);

contentview.setImageViewResource(R.id.image, R.drawable.image1);

contentview.setTextViewText(R.id.text, "hello world");

//将视图赋值给notification

notification.contentView = contentview;

notification.contentIntent = pendingIntent;

//以上代码代替系统的setLatestEventInfo()方法

Intent  intent =  new Intent(Main.this,OtherActivity.class);

PendingIntent pendingIntent =  PendingIntent.getActivity(this, 0, intent, 1);

 

notificationManager.notify(R.id.btn, notification);

    }

}
