Question

我在使用D-pad测试我的应用程序的可聚焦性时遇到问题。这里有我的App的两个截图：

在左侧的图片中，fab是“在列表的外部（或下方）”，在最后一个元素之后，它在向下导航时获得焦点，因此在这种情况下一切正常。问题出在右侧的图像上。工厂位于listView的“内部”，因此（我想但我不确定）它不会成为焦点。有什么可以做的吗？

一个强调就是晶圆厂总是会在列表之前（即紧接着标签之后）获得焦点，无论工厂位于布局中的位置，但问题是我不知道怎么做，因为Android决定了我的布局的焦点顺序。任何帮助都将受到高度赞赏。

Answer 1

您可以创建一个单独的Layout并将您的工厂放在那里。这将迫使那部分永远被看到。

例如

<LinearLayout>
    //list stuff here
    <LinearLayout>
    //fab stuff
    </LinearLayout>
</LinearLayout>

Fab有时只关注焦点
