实现

    public void sendImg(String path, String toUserId) throws Exception {
        Class AccountInstance = mHookClassLoader.loadClass("org.telegram.messenger.AccountInstance");
        Class SendMessageParams = mHookClassLoader.loadClass("org.telegram.messenger.SendMessagesHelper$SendMessageParams");

        Object accountInstance = XposedHelpers.callStaticMethod(AccountInstance, "getInstance", 0);
        Object sendMessagesHelper = XposedHelpers.callMethod(accountInstance, "getSendMessagesHelper");
        Object tLRPC$TL_photo = XposedHelpers.callMethod(sendMessagesHelper, "generatePhotoSizes", path, null);
        Map map = Map.of("final", "1", "groupId", "0", "originalPath", path);

        Object sendMessageParams = XposedHelpers.callStaticMethod(SendMessageParams, "of", tLRPC$TL_photo, null, 0, null, null, null, null, null, map, true, 0, 0, null, false, false);

        XposedHelpers.setLongField(sendMessageParams, "peer", Long.parseLong(toUserId));
        XposedHelpers.callMethod(sendMessagesHelper, "sendMessage", sendMessageParams);
    }
