Android Wear: Creating Lists 麻烦

Question

我对 Android 相当陌生，对 Android Wear 开发完全陌生。最终，我的目标是动态创建一个包含 10 个项目的列表。每个项目都有一个 Image 和一个 TextView。我正在尝试实施此处给出的示例：https://developer.android.com/training/wearables/ui/lists.html。在这个例子中我唯一改变的是 res/layout/list_item.xml 文件：ImageView 没有 src。相反，我将背景颜色设置为哈希值。我还将 TextView.textColor 更改为哈希值。

一切编译正常，我可以通过蓝牙将应用程序安装到我的 Moto 360 上。但是，当我在我的 Moto 360 上打开该应用程序时，会出现一条错误消息 "Unfortunately, myApp has stopped." 我所知道的是，如果我注释掉这一行：

listView.setAdapter(new Adapter(this, elements));

在WearActivity.onCreate方法中，然后没有出现错误，但是现在app的内容是空白的。任何帮助都会很棒！谢谢。
