本文奉上一个Android移动数据开关开启关闭方法，闲话少说，直接上代码。

public static void setDataEnabled(int slotIdx, boolean enable,Context context) throws Exception
{
    try {
        int subid = SubscriptionManager.from(context).getActiveSubscriptionInfoForSimSlotIndex(slotIdx).getSubscriptionId();
        TelephonyManager telephonyService = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        Method setDataEnabled = telephonyService.getClass().getDeclaredMethod("setDataEnabled", int.class, boolean.class);
        if (null != setDataEnabled) {
            setDataEnabled.invoke(telephonyService, subid, enable);
            LogUtil.LOGD(TAG,"setDataEnabled suc",false);
        }
    }catch (Exception e)
    {
        e.printStackTrace();
        LogUtil.LOGD(TAG,"setDataEnabled exception",false);
    }
}

public static boolean getDataEnabled(int slotIdx,Context context) throws Exception
{
    boolean enabled = false;
    try {
        int subid = SubscriptionManager.from(context).getActiveSubscriptionInfoForSimSlotIndex(slotIdx).getSubscriptionId();
        TelephonyManager telephonyService = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        Method getDataEnabled = telephonyService.getClass().getDeclaredMethod("getDataEnabled", int.class);
        if (null != getDataEnabled) {
            enabled =  (Boolean) getDataEnabled.invoke(telephonyService, subid);
        }
    }catch (Exception e)
    {
        e.printStackTrace();
    }

    return enabled;
}

另外，控制移动数据开关需要一个系统权限
