约束布局-Textview大小增加时会与其他视图重叠 [英] Constraint Layout - Textview overlaps other views when it grows in size

问题描述

上图显示了我希望我的视图如何显示. 问题是，当上部重力文本的大小增加时，会将图像推离视图.我尝试使用障碍，但无法使其正常工作. 下图显示了我为实现这一目标已经走了多远.但是，现在的问题是图像始终停留在末尾.但是我希望它紧靠重力文本，并且当该文本增加时，它应该停留在末尾，并且重力文本的高度应该增加.

Above image shows how i want my view to look like. Problem is when upper gravity text increases in size it pushes the image out off the view. I tried using barriers, but couldn't make it work. Below image shows, how far i have come to achieving this. But now that problem is images are always stuck at the end. But i want it to be right next to gravity text and when that text increase,it should stuck at the end and gravity text should grow in height.

推荐答案

您可以将title_tv(宽度为wrap_content)，imageView4和user_count_tv与packed放在水平链中样式和0的偏差以使其与左侧对齐.当title_tv展开时，您需要使用app:layout_constrainedWidth="true"防止其将其他视图推出边界.约束应该是这样的:

What you can do is put title_tv (with wrap_content width), imageView4 and user_count_tv in a horizontal chain with the packed style and a bias of 0 to have them aligned to the left. When the title_tv expands, you need to use app:layout_constrainedWidth="true" to prevent it from pushing the other views out of bounds. This is what the constraints should look like:
