问题描述

我们如何像LinearLayout一样平均地约束空间中的空间?
例如,如果使用约束编写下面的布局,会变成怎样?

How can we spare space equally in a Constraint Layout as in LinearLayout?
For instance, how would the below layout become if it was written with constraints?

<LinearLayout 
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="horizontal">

  <TextView
    android:id="A"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1" />

  <TextView
    android:id="B"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1" />

  <TextView
    android:id="C"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1" />

  <TextView
    android:id="D"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1" />
</LinearLayout>

在约束布局中,我可以将AD设置为边缘,将A←B→D的偏移设置为33,将A←C→D的偏移设置为66,以使每个元素之间具有相同的间距.但是,该解决方案并不能真正扩展规模.

In a Constraint Layout, I could set A and D to the edges, A←B→D with a 33 bias and A←C→D with a 66 bias to kind of have equal space between each element.
That solution does not really scale though.

在约束布局中有正确的方法吗?

Is there a proper way to do this in Constraint Layout?

推荐答案

FYI-约束布局alpha 9 添加了链,可让您实现此行为.

FYI -- Constraint Layout alpha 9 added Chains, which allow you to implement this behavior.
