Android 桌面角标在各大品牌机型上的实现

原文：https://blog.csdn.net/uyy203/article/details/70160752

由于角标在Android原生的系统中没有支持，所以各个Android手机厂商各自为政。

正如很多资料所说，这一功能完全是效仿IOS，Android本不存在的，对于不支持的厂商如魅族、中兴、酷派，必须为他们不盲目跟风而点赞。

做起适配来，真的很麻烦，要针对各个厂商逐个去写以及测试。

目前做到支持小米、华为、三星、LG、VIVO、ZUK、HTC、NOVA等厂商的Andorid系统

效果如下图所示

特别说明一下小米自MIUI6.0以后，角标的显示和通知栏Notification绑在一起。目前我发现的做法，就只有小米需要和Notification绑在一起才能生效。

不过我在这里的例子因产品需求，全部机型的做法都把Notification绑上。

消息通知ID

private int MQTT_IM_NOTIFICATION_ID=1007;

通知栏Notification的定义

String content = 2 + "个联系人发了" + i + "条消息";
        NotificationCompat.Builder builder = new NotificationCompat.Builder(getBaseContext());
        builder.setSmallIcon(R.drawable.chat_notify_icon);
        builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));
        builder.setTicker("收到" + i + "条消息");
        builder.setWhen(System.currentTimeMillis());
        Intent intent = new Intent(getBaseContext(), MainActivity.class);
 
        intent.setAction(getApplicationContext().getPackageName());
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pi = PendingIntent.getActivity(getBaseContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        builder.setContentIntent(pi);
        builder.setContentTitle(getResources().getText(R.string.app_name));
        builder.setContentText(content);
 
        final Notification n = builder.build();
        int defaults = Notification.DEFAULT_LIGHTS;
 
        defaults |= Notification.DEFAULT_SOUND;
 
        defaults |= Notification.DEFAULT_VIBRATE;
 
 
        n.defaults = defaults;
        n.flags = Notification.FLAG_SHOW_LIGHTS | Notification.FLAG_AUTO_CANCEL;

String content = 2 + "个联系人发了" + i + "条消息";
        NotificationCompat.Builder builder = new NotificationCompat.Builder(getBaseContext());
        builder.setSmallIcon(R.drawable.chat_notify_icon);
        builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));
        builder.setTicker("收到" + i + "条消息");
        builder.setWhen(System.currentTimeMillis());
        Intent intent = new Intent(getBaseContext(), MainActivity.class);
 
        intent.setAction(getApplicationContext().getPackageName());
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pi = PendingIntent.getActivity(getBaseContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        builder.setContentIntent(pi);
        builder.setContentTitle(getResources().getText(R.string.app_name));
        builder.setContentText(content);
 
        final Notification n = builder.build();
        int defaults = Notification.DEFAULT_LIGHTS;
 
        defaults |= Notification.DEFAULT_SOUND;
 
        defaults |= Notification.DEFAULT_VIBRATE;
 
 
        n.defaults = defaults;
        n.flags = Notification.FLAG_SHOW_LIGHTS | Notification.FLAG_AUTO_CANCEL;

特别注意，小米的通知栏提示需要延时操作才会出现角标，但是偶尔还是没法出现，暂时没有特别好的解决办法，不过目前能保证做到较高的成功率。

除了小米以外，其他实现基本没什么问题。

    //小米
    private static void setBadgeOfXiaomi(final Context context,final Notification notification,final int NOTIFI_ID,final int  num){
 
 
        new Handler().postDelayed(new Runnable() {
 
            @Override
            public void run() {
 
 
                try {
 
                    Field field = notification.getClass().getDeclaredField("extraNotification");
 
                    Object extraNotification = field.get(notification);
 
                    Method method = extraNotification.getClass().getDeclaredMethod("setMessageCount", int.class);
 
                    method.invoke(extraNotification, num);
 
                } catch (Exception e) {
 
                    e.printStackTrace();
                    Log.e("Xiaomi" + " Badge error", "set Badge failed");
 
                }
 
//                mNotificationManager.notify(0,notification);
                NotificationManager notifyMgr = (NotificationManager)(context.getSystemService(NOTIFICATION_SERVICE));
                if(num!=0)notifyMgr.notify(NOTIFI_ID, notification);else notifyMgr.cancel(NOTIFI_ID);
 
 
            }
        },550);
 
    }
