类概述:

一个表示如何使用NotificationManager把一个持久的通知呈现给用户的类。

The Notification.Builder has been added to make it easier to construct Notifications.

添加Notification.Builder使构建Notification更容易。

静态变量:

[java]

/**

* Use all default values (where applicable).

*/

public static final int DEFAULT_ALL = ~0;

/**

* Use the default notification sound. This will ignore any given

* {@link #sound}.

*

* @see #defaults

*/

public static final int DEFAULT_SOUND = 1;

/**

* Use the default notification vibrate. This will ignore any given

* {@link #vibrate}. Using phone vibration requires the

* {@link android.Manifest.permission#VIBRATE VIBRATE} permission.

*

* @see #defaults

*/

public static final int DEFAULT_VIBRATE = 2;

/**

* Use the default notification lights. This will ignore the

* {@link #FLAG_SHOW_LIGHTS} bit, and {@link #ledARGB}, {@link #ledOffMS}, or

* {@link #ledOnMS}.

*

* @see #defaults

*/

public static final int DEFAULT_LIGHTS = 4;

定义了默认的灯、震动、声音和全部属性。震动的话需要添加android.permission.VIBRATE权限。

[java]

* Use this constant as the value for audioStreamType to request that

* the default stream type for notifications be used.Currently the

* default stream type is STREAM_RING.

*/

public static final int STREAM_DEFAULT = -1;

notification默认的音频类型。

[java]

/**

* Bit to be bitwise-ored into the {@link #flags} field that should be

* set if you want the LED on for this notification.

* <ul>

* <li>To turn the LED off, pass 0 in the alpha channel for colorARGB

*or 0 for both ledOnMS and ledOffMS.</li>

* <li>To turn the LED on, pass 1 for ledOnMS and 0 for ledOffMS.</li>

* <li>To flash the LED, pass the number of milliseconds that it should

*be on and off to ledOnMS and ledOffMS.</li>

* </ul>

* <p>

* Since hardware varies, you are not guaranteed that any of the values

* you pass are honored exactly.Use the system defaults (TODO) if possible
