Android Match Constraint标签？在约束中同样填充imageViews

时间：2018-04-10 21:26:15

标签： java android android-layout

我试图用3个imageViews填充我的应用程序的一部分。我希望他们平等地填补约束。当我将高度设置为设定数字（例如150dp）时，在较小的屏幕上，视图会显示布局。我已经尝试将宽度设置为0dp，match_parent和wrap_content。似乎没什么用。我还尝试添加一个线性布局来放置imageViews，但这并没有帮助。这是我的XMl。我还提供了一张3.7英寸显示屏上视图的图片。

这几乎回答了这个问题：LinearLayout with two children of equal width使用linearlayout来解决类似的问题。

如果您要使用 ConstraintLayout 在屏幕上平均设置3张图像，则可以如下使用指南

在这里，我将垂直指南设置为屏幕的 80％。您可以根据需要进行自定义。
