实现了自己的notification，需要利用RemoteView来实现自定义布局，这里就来举一个示例，方便理解。

第一步：新建一个工程，命名为cusNotification；

第二步：新建一个布局文件(即自定义的notification的布局文件:custom_notification.xml，内容如下：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <ImageView     android:id="@+id/image"        android:layout_width="wrap_content"        android:layout_height="fill_parent"        android:layout_alignParentLeft="true"        android:layout_marginRight="10dp"        android:contentDescription="@string/Image" />    <TextView         android:id="@+id/title"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_toRightOf="@id/image"        style="@style/NotificationTitle" />        <TextView         android:id="@+id/text"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_toRightOf="@id/image"        android:layout_below="@id/title"        style="@style/NotificationText" />    </RelativeLayout>

?第三步：新建上面布局文件中引用到的styyes.xml文件，代码如下：

<?xml version="1.0" encoding="utf-8"?><resources>    <style name="NotificationText" parent="android:TextAppearance.StatusBar.EventContent" />    <style name="NotificationTitle" parent="android:TextAppearance.StatusBar.EventContent.Title" /></resources>

?第四步：修改java源文件，代码如下：

public class CusNotificationActivity extends Activity {private static final int CUSTOM_VIEW_ID = 1;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                //Notification notification = new Notification();        int icon = R.drawable.ic_launcher;        CharSequence tickerText = "Notification01";        long when = System.currentTimeMillis();        Notification notification = new Notification(icon, tickerText, when);                RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);        contentView.setImageViewResource(R.id.image, R.drawable.notification_image);        contentView.setTextViewText(R.id.title, "Custom notification");        contentView.setTextViewText(R.id.text, "This is a custom layout");        notification.contentView = contentView;                Intent notificationIntent = new Intent(this, CusNotificationActivity.class);        PendingIntent contentIntent = PendingIntent.getActivity(CusNotificationActivity.this, 0, notificationIntent, 0);        notification.contentIntent = contentIntent;                String ns = Context.NOTIFICATION_SERVICE;        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);        mNotificationManager.notify(CUSTOM_VIEW_ID, notification);    }}

这里主要是讲解自定义布局notification的实现，并没有做出很炫的效果！就到这吧！
