Android高仿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 = ; //
