我真的需要帮助，我正在用头撞砖墙。这是行不通的。它根本不会发送 int。我跟着一个指南。我已经尽力了它就是不会发送，有没有人知道更好的方法？我应该做一个全球性的吗？这样会更好吗，但我不确定 id 是怎么做到的，因为我似乎对可以在 canvas 表盘服务中使用的代码有限制。

我想要的只是将一个整数从一个 activity 发送到另一个。使用表盘服务而不是伴侣。我想学习。因此，如果您确实回答了，请不要直接粘贴代码，除非直接粘贴代码更容易，我可以跟随它并破译它。

感谢您的帮助。

<-- 旧虽然我了解如何在 java 中制作一个简单的应用程序，它可以保存用户对单选按钮的选择，然后将其放在单独的 activity 中，例如更改文本的颜色，但我已经点击了我在 android wear.

中努力做到这一点

原因是我无法实现以下内容。

@overide
public void onCreate(Bundle savedInstanceState){
     super.onCreate(savedInstanceState);
      Radiogroup = (RadioGroup)findViewById(R.id.myyrad);
      Radiogroup.setOnCheckedChangedListener(new OnCheckedChangedListener()) { ....

壁纸服务无法实现以下功能？

还有其他选择吗？还是我必须走极其混乱的 googleapiclient 路线？如有任何帮助，我们将不胜感激。

已解决。教程或我的代码都没有问题。 Studio 正在寻找不同的 android 播放服务。在 gradel
