Android Logo消息角标数字提醒

1.添加依赖

implementation "me.leolin:ShortcutBadger:1.1.22@aar"

依赖github地址

https://github.com/leolin310148/ShortcutBadger

2.创建service

public class BadgeIntentService extends IntentService {

    private int notificationId = 0;

    public BadgeIntentService() {
        super("BadgeIntentService");
    }

    private NotificationManager mNotificationManager;

    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        if (intent != null) {
            int badgeCount = intent.getIntExtra("badgeCount", 0);

            mNotificationManager.cancel(notificationId);
            notificationId++;

            Notification.Builder builder = new Notification.Builder(getApplicationContext())
                    .setContentTitle("")
                    .setContentText("")
                    .setSmallIcon(R.mipmap.ic_launcher);
            Notification notification = builder.build();
            ShortcutBadger.applyNotification(getApplicationContext(), notification, badgeCount);
            mNotificationManager.notify(notificationId, notification);
        }
    }
}

3.工具类

public class BadgeUtil {
    public static void applyBadgeCount(Context context, int badgeCount) {
        if (Build.MANUFACTURER.equalsIgnoreCase("Xiaomi")) {
            // 判断机型是否是小米
            context.startService(new Intent(context, BadgeIntentService.class).putExtra("badgeCount", badgeCount));
        } else {
            ShortcutBadger.applyCount(context, badgeCount);
        }
    }

    public static void removeBadgeCount(Context context) {
        ShortcutBadger.removeCount(context);
    }
}

4.调用

BadgeUtil.applyBadgeCount(MainActivity.this, 10);//显示角标
BadgeUtil.removeBadgeCount(MainActivity.this);//关闭角标

5.别忘了添加网络权限和声明service
