自定义的Notification

要创建一个自定义的Notification，可以使用RemoteViews。要定义自己的扩展消息，首先要初始化一个RemoteViews对象，然后将它传递给Notification contentView字段，再把PendingIntent传递给contentIntent字段。以下示例代码是完整步骤：

//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);
