Android项目仿UC浏览器和360手机卫士消息常驻栏（通知栏）

之前网上看了下自定义消息栏，通知栏，了解到了notification这个控件，发现uc浏览器等都是这种类型，今天写个demo实现下，如图：

其中每个按钮都有不同的功能，代码如下：

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); 
  // //加载图片 
  // 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)); 
   } 
    
  } 
 
 } 
 
} 

以下是一些属性的设置：

/* 
* 添加声音 
* notification.defaults |=notification.default_sound; 
* 或者使用以下几种方式 
* notification.sound = uri.parse("file:///sdcard/notification/ringer.mp3"); 
* notification.sound = uri.withappendedpath(audio.media.internal_content_uri, "6"); 
* 如果想要让声音持续重复直到用户对通知做出反应，则可以在notification的flags字段增加"flag_insistent" 
* 如果notification的defaults字段包括了"default_sound"属性，则这个属性将覆盖sound字段中定义的声音 
*/ 
/* 
* 添加振动 
* notification.defaults |= notification.default_vibrate; 
* 或者可以定义自己的振动模式： 
* long[] vibrate = {0,100,200,300}; //0毫秒后开始振动，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数组可以定义成想要的任何长度 
* 如果notification的defaults字段包括了"default_vibrate",则这个属性将覆盖vibrate字段中定义的振动 
*/ 
/* 
* 添加led灯提醒 
* notification.defaults |= notification.default_lights; 
* 或者可以自己的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; 
*/ 
/* 
* 更多的特征属性 
* notification.flags |= flag_auto_cancel; //在通知栏上点击此通知后自动清除此通知 
* notification.flags |= flag_insistent; //重复发出声音，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"正在运行"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， 
* //经常与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 
* //如果要使用此字段，必须从1开始 
* notification.iconlevel = ; //
