需求：

定义一个通知栏消息，点击可以跳转到二级界面。

MainActivity：

package org.mobiletrain.notification_demo;import android.os.Bundle;import android.annotation.SuppressLint;import android.app.Activity;import android.app.Notification;import android.app.NotificationManager;import android.app.PendingIntent;import android.content.Intent;import android.view.Menu;import android.view.View;import android.widget.Button;public class MainActivity extends Activity {private Button sendButton,cancelButton;NotificationManager nm;final int NOTIFICATION_ID = 0X100;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);sendButton = (Button)findViewById(R.id.sendBn);cancelButton = (Button)findViewById(R.id.cancelBn);nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);sendButton.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubsend();}});cancelButton.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubcancel();}});}//发送通知信息@SuppressLint("NewApi")private void send(){//写出即将跳转组件的“意图”Intent intent = new Intent(MainActivity.this,SecondActivity.class);//封装一个Pending对象，用来封装将要发生的事。PendingIntent pIntent = PendingIntent.getActivity(MainActivity.this, 0, intent, 0);Notification.Builder builder = new Notification.Builder(MainActivity.this);builder.setAutoCancel(true);    //设置通知栏点击后就消失。builder.setTicker("您有新消息啦！");  //设置提示信息builder.setSmallIcon(android.R.drawable.ic_menu_add);  //设置通知的图标builder.setContentTitle("有一条新消息"); //设置通知的标题builder.setContentText("您中了500万，点击查看详情");//设置通知的内容builder.setDefaults(Notification.DEFAULT_ALL); //设置声音，振动，led灯等操作builder.setWhen(System.currentTimeMillis());   //设置发送时间builder.setContentIntent(pIntent);  //设置将要发生的跳转组件的意图Notification notification = builder.getNotification();//获取通知对象nm.notify(NOTIFICATION_ID, notification);   //发送通知//}private void cancel(){nm.cancel(NOTIFICATION_ID);                  //取消通知}}

activity_main.xml文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".MainActivity" >    <Button        android:id="@+id/sendBn"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_alignParentTop="true"        android:layout_centerHorizontal="true"        android:layout_marginTop="50dp"        android:text="发送通知" />    <Button        android:id="@+id/cancelBn"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_below="@+id/sendBn"        android:layout_centerHorizontal="true"        android:layout_marginTop="30dp"        android:text="取消通知" /></RelativeLayout>

第二级界面的xml文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:padding="20dp"    android:background="#f00" >    <TextView        android:id="@+id/tv_title"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="中大奖了！！！"        android:textAppearance="?android:attr/textAppearanceLarge" />    <TextView        android:id="@+id/textView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="恭喜您被《非常6+1》选为幸运观众，中了500万大奖！！！！" /></LinearLayout>
