如何在 Redmi 上使用应用程序图标显示徽章数量？

Question

我可以使用以下代码在三星设备上显示带有应用程序图标的徽章计数 -

<uses-permission android:name="com.sec.android.provider.badge.permission.READ" />
<uses-permission android:name="com.sec.android.provider.badge.permission.WRITE" />

    Intent intent = new Intent("android.intent.action.BADGE_COUNT_UPDATE");
    intent.putExtra("badge_count", badgeCount);
    intent.putExtra("badge_count_package_name", componentName.getPackageName());
    intent.putExtra("badge_count_class_name", componentName.getClassName());
sendBroadcast(intent);

但我无法在 Redmi 设备上实现这一点，尽管 Facebook、Whatsapp 等能够做到。如果您知道用于广播的操作意图和附加内容，请告诉我。感谢您的帮助。

在小米/小米手机上显示徽章的代码

public static final String INTENT_ACTION = "android.intent.action.APPLICATION_MESSAGE_UPDATE";
public static final String EXTRA_UPDATE_APP_COMPONENT_NAME = "android.intent.extra.update_application_component_name";
public static final String EXTRA_UPDATE_APP_MSG_TEXT = "android.intent.extra.update_application_message_text";
private ResolveInfo resolveInfo;

@Override
public void executeBadge(Context context, ComponentName componentName, int badgeCount) throws ShortcutBadgeException {
    try {
        Class miuiNotificationClass = Class.forName("android.app.MiuiNotification");
        Object miuiNotification = miuiNotificationClass.newInstance();
        Field field = miuiNotification.getClass().getDeclaredField("messageCount");
        field.setAccessible(true);
        try {
            field.set(miuiNotification, String.valueOf(badgeCount == 0 ? "" : badgeCount));
        } catch (Exception e) {
            field.set(miuiNotification, badgeCount);
        }
    } catch (Exception e) {
        Intent localIntent = new Intent(
                INTENT_ACTION);
        localIntent.putExtra(EXTRA_UPDATE_APP_COMPONENT_NAME, componentName.getPackageName() + "/" + componentName.getClassName());
        localIntent.putExtra(EXTRA_UPDATE_APP_MSG_TEXT, String.valueOf(badgeCount == 0 ? "" : badgeCount));
        if (BroadcastHelper.canResolveBroadcast(context, localIntent)) {
            context.sendBroadcast(localIntent);
        }
    }
    if (Build.MANUFACTURER.equalsIgnoreCase("Xiaomi")) {
        tryNewMiuiBadge(context, badgeCount);
    }
}

@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
private void tryNewMiuiBadge(Context context, int badgeCount) throws ShortcutBadgeException {
    if (resolveInfo == null) {
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_HOME);
        resolveInfo = context.getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY);
    }

    if (resolveInfo != null) {
        NotificationManager mNotificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Notification.Builder builder = new Notification.Builder(context)
                .setContentTitle("")
                .setContentText("")
                .setSmallIcon(resolveInfo.getIconResource());
        Notification notification = builder.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);
            mNotificationManager.notify(0, notification);
        } catch (Exception e) {
            throw new ShortcutBadgeException("not able to set badge", e);
        }
    }
}

这是从project link上的ShortcutBadger 应用程序的github 复制的代码（我不知道使用此代码的许可/权限）

也许，用户需要从设置中明确启用该选项。参考这里：badge count on launcher icon
