    android:layout_marginBottom="35dip"
    android:visibility="gone" />

我知道我应该添加布局但在哪里？甚至xml预览都无法正常工作。完整错误是这样的：渲染期间引发异常：您必须在include标记中指定布局：

Answer 1

您的示例XML包含＆lt; include＆gt;缺少布局属性的元素。应将layout属性指定为布局资源。您似乎也错过了结束＆lt; / FrameLayout＆gt;标签

    ...
    <include
        layout="@layout/my_layout"
        ... />
</FrameLayout>

对于某些布局XML文件res / layout / my_layout.xml。

Answer 2

在您提供的xml文件中，include标记没有android:layout 必需的perporty。 Learn more details...
