Android桌面图标实现

基于ShortcutBadger实现

The ShortcutBadger makes your Android App show the count of unread messages as a badge on your App shortcut!

ShortcutBadger使用

• 主要实现badge生成和消除功能。

• 一般badge会配合Notifaction使用，故而在生成Notifaction的地方，调用badge生成方法。

• 而当App从后台返回前台时，调用badge清除方法。

测试运行效果

• 测试可行厂商

  • 华为
  • 三星

• 需调试厂商

  • 小米
    • 小米MIUI 6.0开始，发送通知自动生成桌面角标，且默认桌面角标数badge会根据通知ID个数自动累加，点击应用badge自动消失。同时，其提供开放API，可自定义badge个数。
    • 针对小米，在调用端分开处理。

• 未开通桌面图标厂商

  • 魅族

  • 中兴

  • 酷派

  • OPPO部分应用开通

最终代码

• 生成Notifaction和Badge时：

  /**
     * 生成通知和桌面角标
     */
    private void setFlowNotifaction(Context context, Intent resultIntent, String title, String msg) {

        mBadge++;

        // 小米miui6.0以后根据通知自动生成badge,根据通知次数自动累加。调用ShortcutBadger会自动生成空通知，需调用以下修改badge
        if (Build.MANUFACTURER.equalsIgnoreCase("Xiaomi") && Build.VERSION.SDK_INT > Build.VERSION_CODES.JELLY_BEAN) {
            tryNewMiuiBadge(context, resultIntent, mBadge, title, msg, R.drawable.icon_app);
        } else {
            showNotifacitonBadge(context, resultIntent, mBadge, title, msg, R.drawable.icon_app);
        }
    }
    
    private void showNotifacitonBadge(Context context, Intent resultIntent, int badge, String title, String msg, int drawIcon) {
        PendingIntent pendingIntent = PendingIntent.getActivity(context,
                0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(context)
                        .setSmallIcon(drawIcon)
                        .setContentTitle(title)
                        .setContentText(msg)
                        .setTicker(msg);
//        mBuilder.setFullScreenIntent(pendingIntent, true);
        mBuilder.setContentIntent(pendingIntent);
        mBuilder.setAutoCancel(true);


        // 设置通知的优先级
        mBuilder.setPriority(NotificationCompat.PRIORITY_HIGH);
//        Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
//        // 设置通知的提示音
//        mBuilder.setSound(alarmSound);
        mBuilder.setDefaults(Notification.DEFAULT_ALL);


        int mNotificationId = 10086;
        NotificationManager mNotifyMgr = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        mNotifyMgr.notify(mNotificationId, mBuilder.build());
        // 生成桌面角标
        ShortcutBadger.applyCount(JApplication.getInstance(), badge);
    }

    @TargetApi(Build.VERSION_CODES.JELLY_BEAN)
    private void tryNewMiuiBadge(Context context, Intent resultIntent, int badgeCount, String title, String msg, int drawIcon) {

        PendingIntent pendingIntent = PendingIntent.getActivity(context,
                0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(context)
                        .setSmallIcon(drawIcon)
                        .setContentTitle(title)
                        .setContentText(msg)
                        .setTicker(msg);
//        mBuilder.setFullScreenIntent(pendingIntent, true);
        mBuilder.setContentIntent(pendingIntent);
        mBuilder.setAutoCancel(true);


        // 设置通知的优先级
        mBuilder.setPriority(NotificationCompat.PRIORITY_HIGH);
//        Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
//        // 设置通知的提示音
//        mBuilder.setSound(alarmSound);
        mBuilder.setDefaults(Notification.DEFAULT_ALL);


//        int mNotificationId = 10086;
        NotificationManager mNotifyMgr = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = mBuilder.build();

        try {
            Field field = notification.getClass().getDeclaredField("extraNotification");
            Object extraNotification = field.get(notification);
            Method method = extraNotification.getClass().getDeclaredMethod("setMessageCount", int.class);
            method.invoke(extraNotification, badgeCount);

        } catch (Exception e) {
            e.printStackTrace();
        }

        mNotifyMgr.notify(0, notification);
    }

• 消除Badge时：

  App从后台返回前台都需要清除badge，故而现在Activity基类中做统一检测处理

     @Override
      protected void onResume() {
          super.onResume();
          MobclickAgent.onResume(this);
  
          // 小米miui6.0后，会自动清除badge，调用ShortcutBadger会自动生成空通知
          if (mBadge > 0) {
              if (Build.MANUFACTURER.equalsIgnoreCase("Xiaomi") && Build.VERSION.SDK_INT > Build.VERSION_CODES.JELLY_BEAN) {
                  mBadge = 0;
  
              } else {
                  mBadge = 0;
                  ShortcutBadger.applyCount(this, 0);
              }
          }
      }
