Android Notification 的封装复用

Android Notification 的封装复用

在Android应用的开发中，我们难免会在很多地方都用到Notification。为了更加简单的使用以及避免在不同app上写一大串相同的代码，因此对Notification和NotificationManager类进行了封装。

直接边看代码边说吧~~

/**  * @ClassName: NotificationInterface  * @Description: Notification 接口 * @author kaiqi.li  * @date 2015年1月5日 下午3:46:19   */public interface NotificationInterface {public static final String TAG = NotificationInterface.class.getClass().getSimpleName();public NotificationCompat.Builder generateNotifacationBuilder(String title,String content, int iconId) ;}

1、首先定义的是 NotificationInterface ，该接口中主要定义了 generateNotifacationBuilder函数由具体的Notification类实现

/**  * @ClassName: BasicNotificationBuild  * @Description: 默认的 NotificationBuilder * @author kaiqi.li  * @date 2015年1月5日 下午3:50:52   */public class BasicNotificationBuilder implements NotificationInterface {private Context mContext ;private GetPendingIntent mCallback ;public BasicNotificationBuilder(Context context , GetPendingIntent callback){mContext = context ;mCallback = callback ;}/** * 创建一个默认的NotificationBuilder * 设置3个必填参数.setSmallIcon(iconId) *     .setContentTitle(title) * .setContentText(content) */@Overridepublic Builder generateNotifacationBuilder(String title, String content, int iconId) {NotificationCompat.Builder builder = new NotificationCompat.Builder(mContext).setSmallIcon(iconId).setContentTitle(title).setContentText(content).setAutoCancel(true).setDefaults(Notification.DEFAULT_ALL)        .setContentIntent(mCallback.getPendingIntent()) ;return builder;}/** * * @ClassName: GetPendingIntent * @Description: 回调接口，获取具体的PendingIntent以解决用户点击back键时返回到哪个界面的问题* 根据不同的需求可以在getPendingIntent函数的实现中设置不同的PendingIntent* @author kaiqi.li * @date 2015年1月5日 下午5:38:59 */public interface GetPendingIntent{public PendingIntent getPendingIntent() ;}}

2、定义BasicNotificationBuilder类，详细解释的看注释。今后要是有拓展，比如说自定义Notification布局等，可以再定义相应的类（如CustomNotificationBuilder）实现

generateNotifacationBuilder接口就可以了。

<pre name="code" class="java">/**  * @ClassName: MyNotificationManager  * @Description: Notificatoin 管理器 * @author kaiqi.li  * @date 2015年1月5日 下午4:05:50   */public class MyNotificationManager {private NotificationInterface mNotificationInterface ;private static MyNotificationManager instanse ;private NotificationManager notificationManager = null ;private static final int START_ID = 1000;      private static final int RANGE = 50;      private int mCurrentId = START_ID;          private MyNotificationManager(){    }        public static MyNotificationManager getInstanse(){    if (instanse == null ) {synchronized (MyNotificationManager.class) {if (instanse == null) {instanse = new MyNotificationManager() ;}}}    return instanse ;    }        public NotificationInterface getNotificationInterface(){    return mNotificationInterface ;    }    public void  setNotificationInterface(NotificationInterface notificationInterface){    mNotificationInterface = notificationInterface;    }        /**@description 对外发送通知的接口     * @param context     * @param title  标题     * @param content  内容     * @param iconId  图标 id     */    public void sendNotification(Context context ,String title , String content ,int iconId){    buildAndDisplayNotification(context, title, content, iconId);    }    /**@description 创建通知     * @param context     * @param title  标题     * @param content  内容     * @param iconId  图标 id     */    private void buildAndDisplayNotification(Context context ,String title , String content ,int iconId){    if (mNotificationInterface != null) {Notification notification = mNotificationInterface.generateNotifacationBuilder(title, content, iconId).build();if (notification != null) {if (notificationManager == null) {notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);}notificationManager.notify(generateNotification(), notification);}}    }        /**     * @return Notification 的id     */    private int generateNotification() {          mCurrentId++;          if (mCurrentId >= START_ID + RANGE) {              mCurrentId = START_ID;          }          return mCurrentId;      }    }

3、Notificatoin 管理器 ，负责统一发送和管理Notification，可以增加接口实现统一设置Notification的通知响应（如：震动，响铃，闪灯等）

<span style="font-family:Arial, Helvetica, sans-serif;"></span>

以下是调用方式：

<pre name="code" class="java">

BasicNotificationBuilder builder = new BasicNotificationBuilder(context, new GetPendingIntent() {@Overridepublic PendingIntent getPendingIntent() {Intent intent = new Intent(context , Test2.class);TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);// 添加后台堆栈stackBuilder.addParentStack(Test2.class);// 添加Intent到栈顶stackBuilder.addNextIntent(intent);// 获得一个PendingIntent包含整个后台堆栈 containing the entire back stackPendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);return pendingIntent;}});MyNotificationManager.getInstanse().setNotificationInterface(builder);MyNotificationManager.getInstanse().sendNotification(context, "通知标题", "通知内容", R.drawable.icon);
