xiaomi：
当应用向通知栏发送了一条通知 （除了进度条样式和常驻通知外），应用图标的右上角就会显示「1」。值得一提，角标的数字代表应用的通知数，即应用发送了「x」条通知，角标就会显示为「x」。
try {
Field field = notification.getClass().getDeclaredField(“extraNotification”);
Object extraNotification = field.get(notification);
Method method = extraNotification.getClass().getDeclaredMethod(“setMessageCount”, int.class);
method.invoke(extraNotification, mCount);

新版本：
新款的OPPO角标功能仅支持内置应用、微信和QQ显示角标，若要使用角标功能，必须提交申请，审核通过了才能开放，官方给的具体审核标准如下：
申请角标接入规则（应用必须适配OPPO手机，保证角标功能测试通过）
a) 系统应用；
b) 国内外各区域用户量排名Top5的三方即时通讯类应用，且只允许显示即时通信消息类通知（如QQ、微信、facebook、line）；
c) OPPO公司内部费商业化及运营性质的办公类型即时通信应用（如Teamtalk）；
d) 国内外邮件类应用（各区域各属于用户量第一梯队的应用）。
vivo：
桌面图标角标”默认关闭，需要用户手动开启。
开启路径：“设置”-“通知与状态栏”-“应用通知管理”-应用名称-“桌面图标角标”。
未成功接入“桌面图标角标”的应用，无“桌面图标角标”选项。
备注：视OS版本差异，“桌面图标角标”名称可能为“应用图标标记”或“桌面角标”。
a. 添加权限：
uses-permission android:name="com.vivo.notification.permission.BADGE_ICON" /
b. 应用在需要显示桌面角标的场景，通过广播将信息发送给vivoLauncher：
广播参数：
action：launcher.action.CHANGE_APPLICATION_NOTIFICATION_NUM
packageName：应用包名
className：主类名
notificationNum：未读消息数目
简单示例：
Intent intent = new Intent();
int missedCalls = 10;
intent.setAction("launcher.action.CHANGE_APPLICATION_NOTIFICATION_NUM");
intent.putExtra("packageName", "com.android.xxxx");
intent.putExtra("className", "com.android.xxxx.Mainxxxx");
intent.putExtra("notificationNum", missedCalls);
intent.addFlags(Intent.FLAG_RECEIVER_INCLUDE_BACKGROUND);
sendBroadcast(intent);
注意：
在8.0上，还需要给Intent加上下面的flag
Intent.FLAG_RECEIVER_INCLUDE_BACKGROUND
sansung：
private static boolean setSamsungBadge(int count, Context context) {

context.sendBroadcast(intent);
return true;
} catch (Exception e) {

角标实现
要实现这个角标：
1、放置一个隐藏的图片在app中，在需要它显示的时候，显示该图片，并以该图片为背景，显示新增消息数；
2、自定义一个控件，用于显示该角标信息。例如，角标相对于控件的位置、底色、数字等；
对比或者使用后，你会发现，自定义一个控件，无疑更符合我们的使用习惯。无需特定的图片，减少了app的大小等，更重要的是，这样方便我们的使用。
在角标实现中，有个开源代码BadgeView写的很符合我们的心理预期。实现了我们常用的所有功能。
BadgeView
这是一个继承TextView控件，自定义而成的一个简单控件。我们通过它，可轻易实现对角标位置、角标底色、角标内容等控制。
