• 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 = ; //
