main 代码：：：

public void click1(View view) {

NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

Notification notification = new Notification(R.drawable.ic_launcher, "我是滚动的文本",System.currentTimeMillis());

notification.flags = Notification.FLAG_AUTO_CANCEL;

RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.customview);

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

contentView.setTextViewText(R.id.title, "Custom notification");

contentView.setTextViewText(R.id.text, "This is a custom layout");

notification.contentView = contentView;

Intent intent = new Intent();

intent.setAction(Intent.ACTION_VIEW);

intent.setData(Uri.parse("http://www.baidu.com"));

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);

notification.contentIntent = contentIntent;

// notification.setLatestEventInfo(this, "我是大的标题", "我是标题下面的内容", contentIntent);

nm.notify(0, notification);

}

自定义布局：：：

android:id="@+id/layout"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:padding="10dp" >

android:layout_width="wrap_content"

android:layout_height="fill_parent"

android:layout_alignParentLeft="true"

android:layout_marginRight="10dp" />

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_toRightOf="@id/image"

style="@style/NotificationTitle" />

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_toRightOf="@id/image"

android:layout_below="@id/title"

style="@style/NotificationText" />

Style 样式里：：

<?xml version="1.0" encoding="utf-8"?>

<resources>
    <style name="NotificationText">
      <item name="android:textColor">?android:attr/textColorPrimary</item>
    </style>
    <style name="NotificationTitle">
      <item name="android:textColor">?android:attr/textColorPrimary</item>
      <item name="android:textStyle">bold</item>
    </style>
    <!-- If you want a slightly different color for some text,
         consider using ?android:attr/textColorSecondary -->
</resources>
