这个例子的Icons Only 和 Icons and marquee 没有什么特别好说明的。
而Use Remote views in balloon 介绍了可以自定义在Extended Status bar显示Notification的Layout，Extended Status Bar缺省显示Notification 是一个图标后接文字，对应大多数情况是够用了。但如果有需要也可以使用自定义的Layout在Extented Status bar显示Notification，方法是通过RemoteView：
[java]
private void setMoodView(int moodId, int textId) {
Notification notif = new Notification();
notif.contentIntent = makeMoodIntent(moodId);
CharSequence text = getText(textId);
notif.tickerText = text;
// the icon for the status bar
notif.icon = moodId;
// our custom view
RemoteViews contentView = new RemoteViews(getPackageName(),
R.layout.status_bar_balloon);
contentView.setTextViewText(R.id.text, text);
contentView.setImageViewResource(R.id.icon, moodId);
contentView.setImageViewResource(R.id.icon1, moodId);
notif.contentView = contentView;
mNotificationManager.notify(R.layout.status_bar_notifications,
notif);
}
private void setMoodView(int moodId, int textId) {
Notification notif = new Notification();
notif.contentIntent = makeMoodIntent(moodId);
CharSequence text = getText(textId);
notif.tickerText = text;
// the icon for the status bar
notif.icon = moodId;
// our custom view
RemoteViews contentView = new RemoteViews(getPackageName(),
R.layout.status_bar_balloon);
contentView.setTextViewText(R.id.text, text);
contentView.setImageViewResource(R.id.icon, moodId);
contentView.setImageViewResource(R.id.icon1, moodId);
notif.contentView = contentView;
mNotificationManager.notify(R.layout.status_bar_notifications,
notif);
}
为了和缺省的Status Bar Layout有所区别，我们在/res/status_bar_balloon.xml 在增加一个ImageView：左右各显示一个图标，中间为文字。
<LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android”
android:orientation=”horizontal”
android:baselineAligned=”false”
android:gravity=”center_vertical”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”>
<ImageView android:id=”@+id/icon”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:layout_marginRight=”10dip” />
<TextView android:id=”@+id/text”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:textColor=”#ffffffff” />
<ImageView android:id=”@+id/icon1″
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:layout_marginRight=”10dip” />
</LinearLayout>
Use default values where applicable 介绍使用缺省声音，震动或是两者的方法：
[java]
int default = Notification.DEFAULT_SOUND;
//Notification.DEFAULT_SOUND
//Notification.DEFAULT_VIBRATE
//Notification.DEFAULT_ALL
notification.defaults = defaults;
int default = Notification.DEFAULT_SOUND;
//Notification.DEFAULT_SOUND
//Notification.DEFAULT_VIBRATE
//Notification.DEFAULT_ALL
notification.defaults = defaults;
