1.activity_main.xml：

2.layout_item.xml：

3.activity_detail.xml：

4.SingletonF类：

/**
*用于存储消息数目
*Createdbyadminon2017/9/4.
*/

publicclassSingletonF{

privateintinfo_number=0;

privatestaticclassSingletonHolder{
/**
*单例对象实例
*/
staticfinalSingletonFINSTANCE=newSingletonF();
}

publicstaticSingletonFgetInstance(){
returnSingletonHolder.INSTANCE;
}

/**
*private的构造函数用于避免外界直接使用new来实例化对象
*/
privateSingletonF(){}

publicintgetInfo_number(){
returninfo_number;
}

publicvoidsetInfo_number(intinfo_number){
this.info_number=info_number;
}

///**
//*若SingletonFimplementsSerializable则必须实现readResolve方法
//*readResolve方法应对单例对象被序列化时候
//*/
//privateObjectreadResolve(){
//returngetInstance();
//}

}

5.MyBroadcastReceiver类：

importjava.text.SimpleDateFormat;

publicclassMyBroadcastReceiverextendsBroadcastReceiver{

privateSingletonFsingletonF;
privateContextcontext1;

@Override
publicvoidonReceive(Contextcontext,Intentintent){
this.context1=context;
//if(intent.getStringExtra("info").equals("广播发送了")){
//Log.i("静态广播：","广播我已经接受了");
//}
Messagemessage=handler.obtainMessage();
message.what=0;
handler.sendMessage(message);
}

privateHandlerhandler=newHandler(){
@Override
publicvoidhandleMessage(Messagemsg){
switch(msg.what){
case0:
singletonF=SingletonF.getInstance();
intfirst=singletonF.getInfo_number();
first++;
DatenowTime=newDate(System.currentTimeMillis());
SimpleDateFormatsdFormatter=newSimpleDateFormat("HH:mm");
StringretStrFormatNowDate=sdFormatter.format(nowTime);
singletonF.setInfo_number(first);

RemoteViewscontentViews=newRemoteViews(context1.getPackageName(),R.layout.layout_item);
//通过控件的Id设置属性
contentViews.setImageViewResource(R.id.imageView1,R.mipmap.ic_launcher_round);
contentViews.setTextViewText(R.id.textView1,"消息标题");
contentViews.setTextViewText(R.id.textView2,"消息内容");
contentViews.setTextViewText(R.id.textView3,"("+first+"条新消息)");
contentViews.setTextViewText(R.id.textView4,""+retStrFormatNowDate);
//点击通知栏跳转的activity
Intentintent=newIntent(context1,ActDetail.class);
PendingIntentpendingIntent=PendingIntent.getActivity(context1,0,intent,
PendingIntent.FLAG_CANCEL_CURRENT);

NotificationCompat.BuildermBuilder=newNotificationCompat.Builder(context1)
.setSmallIcon(R.mipmap.ic_launcher_round).setTicker("newmessage");
//自动管理通知栏消息
mBuilder.setAutoCancel(true);
mBuilder.setContentIntent(pendingIntent);
///自定义布局
mBuilder.setContent(contentViews);
//使用默认提示音
mBuilder.setDefaults(Notification.DEFAULT_ALL);
NotificationManagermNotificationManager=(NotificationManager)context1
.getSystemService(context1.NOTIFICATION_SERVICE);
//notify(intid,Notificationnotification)若id为同一个值，则通知栏只会显示一行，并不停更新此消息内容
//若为类似UUID.randomUUID().hashCode()这样不同的唯一标识符，则有几条消息通知栏就显示几行
mNotificationManager.notify(1,mBuilder.build());

break;
default:
break;
}
}
};

}

6.MainActivity类：

privateintbtn_number=0;

@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

tv_show=(TextView)this.findViewById(R.id.tv_show);
tv_show.setOnClickListener(newView.OnClickListener(){
@Override
publicvoidonClick(Viewview){
showNotify();
btn_number++;
tv_show.setText("发送了"+btn_number+"次广播");
}
});
}

privatevoidshowNotify(){
Intentintent=newIntent();
intent.setAction("MASSAGE_NOTIFICATION");
//intent.putExtra("info","广播发送了");
sendBroadcast(intent);
}

@Override
protectedvoidonStop(){
btn_number=0;
