约束基于维＆QUOT;其他＆QUOT;尺寸 [英] constrain dimension based on "other" dimension

问题描述

我想创建使得维度之一是基于重量的图。不过，我想这种观点具有特定的纵横比。在这种情况下，我希望它是正方形。

I want to create a view such that one of the dimensions is based on a weight. However, I want that view to have a particular aspect ratio. In this case, i want it to be square.

所以我风有这样的事情：

So I wind up having something like this:

<ImageView
    android:id="@+id/MyPicture"
    android:layout_width="???"
    android:layout_height="0"
    android:layout_weight="2"
    android:scaleType="fitXY"
    android:src="@drawable/mypicture"/>

我怎样才能做到这一点？

How can I achieve this?

推荐答案

您会做在Java中code。有一个在XML没有办法指定一个维度是依赖于另一维度。

You would have to do that in Java code. There is no way in XML to specify one dimension is dependent upon another dimension.
