沉舟侧畔千帆进，病树前头万木春。这篇文章主要讲述Android高仿UC浏览器和360手机卫士消息常驻栏（通知栏）相关的知识，希望能为你提供帮助。
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：
【Android高仿UC浏览器和360手机卫士消息常驻栏（通知栏）】

/* * 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 = ; // */
