之前网上看了下自己定义消息栏，通知栏，了解到了Notification这个控件。发现UC浏览器等都是这样的类型，今天写个demo实现下。如图：

当中每一个button都有不同的功能。代码例如以下：

package com.example.textwsjdemo;

import android.app.Activity;

import android.app.Notification;

import android.app.NotificationManager;

import android.app.PendingIntent;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.content.IntentFilter;

import android.os.Bundle;

import android.view.KeyEvent;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.RemoteViews;

import android.widget.Toast;

public class MainActivity extends Activity {

private Button bt_hehe;

private NotificationManager notificationManager;

private Notification notification;

private int icon;

private CharSequence tickerText;

private long when;

RemoteViews contentView;

private Intent intent;

private PendingIntent pendingIntent;

private int notification_id = 0;

private MyBroadCast receiver;

private static String ACTION = "a";

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

receiver = new MyBroadCast();

IntentFilter filter = new IntentFilter();

filter.addAction("a");

filter.addAction("b");

filter.addAction("c");

filter.addAction("d");

registerReceiver(receiver, filter);

initView();

initData();

}

private void initData() {

icon = R.drawable.ic_launcher; // 通知图标

tickerText = "Hello"; // 状态栏显示的通知文本提示

when = System.currentTimeMillis(); // 通知产生的时间，会在通知信息里显示

}

private void initView() {

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

bt_hehe.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

// 启动提示栏

createNotification();

}

});

}

private void createNotification() {

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

notification = new Notification();

notification.icon = icon;

notification.tickerText = tickerText;

notification.when = when;

/***

* 在这里我们用自定的view来显示Notification

*/

contentView = new RemoteViews(getPackageName(),

R.layout.notification_item);

contentView.setTextViewText(R.id.text11, "小说");

contentView.setTextViewText(R.id.text22, "视频");

contentView.setTextViewText(R.id.text33, "新闻");

contentView.setTextViewText(R.id.text44, "扯淡");

// contentView.setTextViewText(R.id.notificationPercent, "0%");

// contentView.setProgressBar(R.id.notificationProgress, 100, 0, false);

// //进度条

// contentView.setImageViewResource(R.id.image,R.drawable.more_advice);

// //载入图片

// contentView.setImageViewResource(R.id.image,R.drawable.more_attention);

// contentView.setImageViewResource(R.id.image,R.drawable.more_evaluate);

// contentView.setImageViewResource(R.id.image,R.drawable.more_about);

// contentView.setTextViewText(R.id.text,"Hello,this message is in a custom expanded view");

// //文本

notification.flags = Notification.FLAG_ONGOING_EVENT; // 设置常驻。不能滑动取消

//默认跳转的主界面

intent = new Intent(this, MainActivity.class);

intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

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

//自己定义跳转

contentView.setOnClickPendingIntent(R.id.ll_11, PendingIntent.getBroadcast(MainActivity.this, 11, new Intent().setAction("a"), PendingIntent.FLAG_UPDATE_CURRENT));

contentView.setOnClickPendingIntent(R.id.ll_22, PendingIntent.getBroadcast(MainActivity.this, 11, new Intent().setAction("b"), PendingIntent.FLAG_UPDATE_CURRENT));

contentView.setOnClickPendingIntent(R.id.ll_33, PendingIntent.getBroadcast(MainActivity.this, 11, new Intent().setAction("c"), PendingIntent.FLAG_UPDATE_CURRENT));

contentView.setOnClickPendingIntent(R.id.ll_44, PendingIntent.getBroadcast(MainActivity.this, 11, new Intent().setAction("d"), PendingIntent.FLAG_UPDATE_CURRENT));

notification.contentView = contentView;

notification.contentIntent = pendingIntent;

notificationManager.notify(notification_id, notification);

}

// 取消通知

private void cancelNotification() {

notificationManager.cancelAll();

}

@Override

protected void onDestroy() {

cancelNotification();

unregisterReceiver(receiver);

}

@Override

public boolean onKeyDown(int keyCode, KeyEvent event) {

if ((keyCode == KeyEvent.KEYCODE_BACK)) {

System.out.println("按下了back键 onKeyDown()");

cancelNotification();

}

return super.onKeyDown(keyCode, event);

}

class MyBroadCast extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

if(intent.getAction().equals("a")){

Toast.makeText(MainActivity.this, "11111111111111",

Toast.LENGTH_LONG).show();

startActivity(new Intent(MainActivity.this, ActivityText1.class));

}

if(intent.getAction().equals("b")){

Toast.makeText(MainActivity.this, "222222222222222",

Toast.LENGTH_LONG).show();

startActivity(new Intent(MainActivity.this, ActivityText2.class));

}

if(intent.getAction().equals("c")){

Toast.makeText(MainActivity.this, "333333333333",

Toast.LENGTH_LONG).show();

startActivity(new Intent(MainActivity.this, ActivityText3.class));

}

if(intent.getAction().equals("d")){

Toast.makeText(MainActivity.this, "4444444444444",

Toast.LENGTH_LONG).show();

startActivity(new Intent(MainActivity.this, ActivityText4.class));

}

}

}

}

下面是一些属性的设置：

/*

* 加入声音

* notification.defaults |=Notification.DEFAULT_SOUND;

* 或者使用下面几种方式

* notification.sound = Uri.parse("file:///sdcard/notification/ringer.mp3");

* notification.sound = Uri.withAppendedPath(Audio.Media.INTERNAL_CONTENT_URI, "6");

* 假设想要让声音持续反复直到用户对通知做出反应，则能够在notification的flags字段添加"FLAG_INSISTENT"

* 假设notification的defaults字段包含了"DEFAULT_SOUND"属性，则这个属性将覆盖sound字段中定义的声音

*/

/*

* 加入振动

* notification.defaults |= Notification.DEFAULT_VIBRATE;

* 或者能够定义自己的振动模式：

* long[] vibrate = {0,100,200,300}; //0毫秒后開始振动，振动100毫秒后停止，再过200毫秒后再次振动300毫秒

* notification.vibrate = vibrate;

* long数组能够定义成想要的不论什么长度

* 假设notification的defaults字段包含了"DEFAULT_VIBRATE",则这个属性将覆盖vibrate字段中定义的振动

*/

/*

* 加入LED灯提醒

* notification.defaults |= Notification.DEFAULT_LIGHTS;

* 或者能够自己的LED提醒模式:

* notification.ledARGB = 0xff00ff00;

* notification.ledOnMS = 300; //亮的时间

* notification.ledOffMS = 1000; //灭的时间

* notification.flags |= Notification.FLAG_SHOW_LIGHTS;

*/

/*

* 很多其它的特征属性

* notification.flags |= FLAG_AUTO_CANCEL; //在通知栏上点击此通知后自己主动清除此通知

* notification.flags |= FLAG_INSISTENT; //反复发出声音，直到用户响应此通知

* notification.flags |= FLAG_ONGOING_EVENT; //将此通知放到通知栏的"Ongoing"即"正在执行"组中

* notification.flags |= FLAG_NO_CLEAR; //表明在点击了通知栏中的"清除通知"后。此通知不清除，

* //常常与FLAG_ONGOING_EVENT一起使用

* notification.number = 1; //number字段表示此通知代表的当前事件数量，它将覆盖在状态栏图标的顶部

* //假设要使用此字段，必须从1開始

* notification.iconLevel = ; //
