Notification的基本使用
司徒英卓
// 在Android进行通知处理，首先需要重系统哪里获得通知管理器NotificationManager，它是一个系统Service。
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
以一个为例
Notification notify3 = new Notification.Builder(this)
.setSmallIcon(R.drawable.ic_launcher) //icon的图片设置
.setTicker("TickerText:" + "您有新短消息，请注意查收！")//提醒的类容
.setContentTitle("Notification Title")//提醒的标题
.setContentText("This is the notification message")/提醒类容
.setContentIntent(pendingIntent3).setNumber(1).build();
PendingIntent//跳转界面 传递信息用的
示例
intent1 = new Intent(getApplicationContext(),
ContentActivity.class);
intent1.putExtra("content", "444");
intent1.putExtra("number", "444");
intent1.putExtra("date", "444");
PendingIntent contentIntent = PendingIntent.getActivity(this, 1,
intent1, PendingIntent.FLAG_CANCEL_CURRENT);
PendingIntent有一个getActivity方法，第一个参数是上下文，第二个参数 requestCode，第三个参数是 Intent，用来存储信息，第四个参数是对参数的操作标识，常用的就是FLAG_CANCEL_CURRENT和FLAG_UPDATE_CURRENT。
关于第二个参数当requestCode值一样时，后面的就会对之前的消息起作用，所以为了避免影响之前的消息，requestCode每次要设置不同的内容。
myNotify = new Notification();
myNotify.flags = Notification.FLAG_NO_CLEAR;// 不能够自动清除
myNotify.defaults = Notification.DEFAULT_ALL; // 使用默认设置，比如铃声、震动、闪灯
myNotify.flags = Notification.FLAG_AUTO_CANCEL; // 但用户点击消息后，消息自动在通知栏自动消失
//DEFAULT_ALL 使用所有默认值，比如声音，震动，闪屏等等
//DEFAULT_LIGHTS 使用默认闪光提示
//DEFAULT_SOUNDS 使用默认提示声音
//DEFAULT_VIBRATE 使用默认手机震动，需加上<uses-permission android:name="android.permission.VIBRATE" />权限
myNotify.defaults = Notification.DEFAULT_LIGHTS;
//闪光和震动需要添加权限
<!-- 闪光灯权限 -->
<uses-permission android:name=
"android.permission.FLASHLIGHT"
>
<!-- 振动器权限 -->
<uses-permission android:name=
"android.permission.VIBRATE"
></uses-permission></uses-permission>

notifyBuilder.setProgress(100, incr, false);这个设置滚动条
可以写带滚动条的提示
/**
* 带滚动条的提示
*/
public void Pro_Notification() {
manager_n = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notifyBuilder = new NotificationCompat.Builder(this);
notifyBuilder.setContentTitle("Picture Download")
.setContentText("Download in progress")
.setTicker("TickerText:您有新下载消息，请注意查收！")
.setOngoing(true)
.setSmallIcon(R.drawable.ic_launcher);
// Start a lengthy operation in a background thread
new Thread(
new Runnable() {
@Override
public void run() {
int incr;
// Do the "lengthy" operation 20 times
for (incr = 0; incr <= 100; incr += 5) {
// Sets the progress indicator to a max value, the
// current completion percentage, and "determinate"
// state
notifyBuilder.setProgress(100, incr, false);
// Displays the progress bar for the first time.
manager_n.notify(0, notifyBuilder.build());
// Sleeps the thread, simulating an operation
// that takes time
try {
// Sleep for 5 seconds
Thread.sleep( 1000);
} catch (InterruptedException e) {
Log.d("NOTIFICATION", "sleep failure");
}
}
// When the loop is finished, updates the notification
notifyBuilder.setContentText("Download complete")
// Removes the progress bar
.setProgress(0, 0, false);
manager_n.notify(213, notifyBuilder.build());
}
}
// Starts the thread by calling the run() method in its Runnable
).start();
}
manager.notify(NOTIFICATION_FLAG, notify2);中的NOTIFICATION_FLAG是int类型是提示信息的表示重复不会弹出显示
