android之notifiation的例子

通知用于在顶部显示类似ios的push通知之类的，下面是sample代码

package com.example.test;

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;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        Button testBtn = (Button)findViewById(R.id.button1);
        testBtn.setOnClickListener(new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                
                addNotificaction();
            }
        });
    }

    @SuppressWarnings("deprecation")
    protected void addNotificaction() {
        // TODO Auto-generated method stub
        NotificationManager manager = (NotificationManager) this  
                .getSystemService(Context.NOTIFICATION_SERVICE);  
                // 创建一个Notification  
                Notification notification = new Notification();  
                // 设置显示在手机最上边的状态栏的图标  
                notification.icon = R.drawable.ic_launcher;  
                // 当当前的notification被放到状态栏上的时候，提示内容  
                notification.tickerText = "注意了，我被扔到状态栏了";  
                  
                /*** 
                 * notification.contentIntent:一个PendingIntent对象，当用户点击了状态栏上的图标时，该Intent会被触发 
                 * notification.contentView:我们可以不在状态栏放图标而是放一个view 
                 * notification.deleteIntent 当当前notification被移除时执行的intent 
                 * notification.vibrate 当手机震动时，震动周期设置 
                 */  
                // 添加声音提示  
                notification.defaults=Notification.DEFAULT_SOUND;  
                // audioStreamType的值必须AudioManager中的值，代表着响铃的模式  
                notification.audioStreamType= android.media.AudioManager.ADJUST_LOWER;  
                  
                //下边的两个方式可以添加音乐  
                //notification.sound = Uri.parse("file:///sdcard/notification/ringer.mp3");   
                //notification.sound = Uri.withAppendedPath(Audio.Media.INTERNAL_CONTENT_URI, "6");   
                Intent intent = new Intent(this, MainActivity.class);  
                PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);  
                // 点击状态栏的图标出现的提示信息设置  
                notification.setLatestEventInfo(this, "内容提示：", "我就是一个测试文件", pendingIntent);  

                manager.notify(1, notification);  
    }
}
