Question

我有3个textview，其中的文本可以动态更改，我需要使它们彼此相等，其高度大于该高度，并承担全部责任。我正在尝试使用障碍物，但没有得到积极的结果，我也尝试将所有textviews的高度设置为0dp，但是所有textviews都消失了，我可以为一个textview的wrap_content和另一个0dp设置高度，但是然后它们将仅在第一个textview。当我使用linearlayout时，我做到了，但是对于constraintlayout，我不知道该怎么做。

Answer 1

正如Nikos Hidalgo在对您的问题的评论中所述，这是在Stack Overflow上提出的常见问题。我遇到了四种方法来为一组视图实现相同的宽度和/或相同的高度。不幸的是，没有一个是理想的。

这里是一个截屏，显示了达到常用尺寸的四种方法中的三种。该屏幕的XML在本文的结尾。

嵌入式LinearLayout

这可能是最简单的方法。将 TextViews 放置在水平的 LinearLayout 中，将其高度设置为 MATCH_PARENT 。将 LinearLayout 的高度设置为 WRAP_CONTENT ，所有设置都会生效。这种方式的好处是简单。缺点包括嵌套布局的开销以及 LinearLayout 中的任何视图都无法连接到 LinearLayout 之外的任何视图-它们成为孤岛。 >

不可见的视图

这可能是最复杂的处理方式，但根据布局可能还可以。设置屏障以调整一组视图的高度的基本问题是，屏障的位置取决于视图的高度，而视图的高度则取决于屏障的位置。这是一个参考难题，不适用于当前版本的 ConstraintLayout 。

不可见视图解决方案是将要调整高度的视图复制为不可见视图。为这些不可见的视图设置顶部和底部屏障。将可见视图的高度设置为 MATCH_CONSTRAINTS ，然后将顶部连接到顶部障碍，将底部连接到底部障碍。

此方法的好处是它是完全平坦的，仅涉及 ConstraintLayout 。缺点是它增加了要调整的视图数量，其复杂性以及复杂性带来的所有问题。

约束版式大小帮助器

第三种方法是使用自定义ConstraintHelper来更改视图的高度。自定义 ConstraintHelper 会像其他任何视图一样插入到布局的XML中，并引用要调整的视图。

此方法的好处是所有更改都保存在XML中。不利的是，必须引用并维护一个自定义类。

更新宽度/高度的监听器

最后一种方法是使用全局布局侦听器，布局侦听器等自定义编码高度调整。这类似于 ConstraintHelper 方法，但存在于XML外部，可能没有很好地封装。

还可以使用自定义 ConstraintLayout 或自定义 TextView 对自定义视图进行编码，以将视图的高度设置为最大高度。
