Android NotificationManager 和Notification的使用总结

//1、创建一个自 定义的消息布局 view.xml

<?xml
version=

"1.0"

encoding=

"utf-8"

?>

<LinearLayout
xmlns:android=

"http://schemas.android.com/apk/res/android"

android:layout_width=

"fill_parent"

android:layout_height=

"fill_parent"

>

<ImageView
android:id=

"@+id/image"

android:layout_width=

"wrap_content"

android:layout_height=

"fill_parent"

android:layout_marginRight=

"10dp"

/>

<TextView
android:id=

"@+id/text"

android:layout_width=

"wrap_content"

android:layout_height=

"fill_parent"

android:textColor=

"#000"

/>

</LinearLayout>

//2、 在程序代码中使用RemoteViews的方法来定义image和text。然后把RemoteViews对象传到contentView字段

RemoteViews
contentView =

new

RemoteViews(getPackageName(),R.layout.view);

contentView.setImageViewResource(R.id.image,R.drawable.icon);

contentView.setTextViewText(R.id.text,”Hello,

this

message
is in a custom expanded view”);

notification.contentView = contentView;

//3、 为Notification的contentIntent字段定义一个Intent(注意，使用自定义View不需要
setLatestEventInfo()方法)

Intent
notificationIntent =

new

Intent(

this

,Main.

class

);

PendingIntent
contentIntent = PendingIntent.getActivity(

this

,

0

,notificationIntent,

0

);

notification.contentIntent = contentIntent;

//4、发送通知

mNotificationManager.notify(

2

,notification);

// 以下是全部示例代码

//创建一个 NotificationManager的引用

String ns = Context.NOTIFICATION_SERVICE;

NotificationManager mNotificationManager =
(NotificationManager)getSystemService(ns);

// 定义Notification的各种属性

int

icon
= R.drawable.icon;

//通知图标

CharSequence
tickerText =

"Hello"

;

//状态栏显示的通知文本提示

long

when
= System.currentTimeMillis();

//通知产生的时间，会在通知信息里显示

//用上面的属性初始化 Nofification

Notification
notification =

new

Notification(icon,tickerText,when);

RemoteViews
contentView =

new

RemoteViews(getPackageName(),R.layout.view);

contentView.setImageViewResource(R.id.image,
R.drawable.iconempty);

contentView.setTextViewText(R.id.text,

"Hello,this
is JC"

);

notification.contentView = contentView;

Intent
notificationIntent =

new

Intent(

this

,Main.

class

);

PendingIntent
contentIntent = PendingIntent.getActivity(

this

,

0

,notificationIntent,

0

);

notification.contentIntent = contentIntent;

//把Notification传递给NotificationManager

mNotificationManager.notify(

0

,notification);

Java代码


private void initNotification()

{

int notificationID = 10;

NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

// Create the notification

Notification notification = new Notification(R.drawable.clock, "TestActivity已经起动",

System.currentTimeMillis());

notification.flags |= Notification.FLAG_ONGOING_EVENT; // 将此通知放到通知栏的"Ongoing"即"正在运行"组中

notification.flags |= Notification.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，经常与FLAG_ONGOING_EVENT一起使用

notification.flags |= Notification.FLAG_SHOW_LIGHTS; // set LED on

// notification.defaults = Notification.DEFAULT_LIGHTS; //默认Notification lights;

notification.ledARGB = R.color.blue; // LED 颜色;

notification.ledOnMS = 5000; // LED 亮时间

// Create the notification expanded message

// When the user clicks on it, it opens your activity

Intent intent = new Intent(this, TestActivity.class);

PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,

intent, 0);

notification

.setLatestEventInfo(this, "TestActivity", "17:50执行下个任务", pendingIntent);

// Show notification

notificationManager.notify(notificationID, notification);

}

Java代码

public void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

initNotification();

iniTimePick();

}
