Question

我正在使用ConstraintLayout来获取此结构。但是在最后一个图像中，加号图标imageview隐藏了一半。而且，在所有三个图像中，如果设置图像，则加号或叉号的一部分会被隐藏。我尝试设置elevation或tranlationZ，但对我来说不起作用。

请帮助我解决此问题。

这是我的代码段。

Answer 1

尝试此=>您必须为此设置适当的约束条件

将第0个画廊图像结束约束赋予第一个画廊图像的开始约束，将第2个画廊图像起始约束赋予第一个画廊图像的结束约束

您也可以使用链条

            android:paddingEnd="@dimen/_16dp"
            android:paddingStart="@dimen/_16dp"
