约束布局 - Textview 在大小增加时会与其他视图重叠

Question

上图显示了我希望我的视图看起来如何。 问题是当上部重力文本的大小增加时，它会将图像推出视图。我尝试使用障碍，但无法使其工作。 下图显示了我在实现这一目标方面走了多远。但现在这个问题是图像总是卡在最后。但我希望它紧挨着重力文字，当文字增加时，它应该卡在最后，重力文字应该增加高度。

Answer 1

您可以做的是将title_tv（具有wrap_content 宽度）、imageView4 和user_count_tv 放在具有packed 样式和0 偏差的水平链中，以使它们与左边。当title_tv 展开时，您需要使用app:layout_constrainedWidth="true" 来防止它推动其他视图超出范围。约束应该是这样的：

        </android.support.constraint.ConstraintLayout>

    </android.support.v7.widget.CardView>

</android.support.constraint.ConstraintLayout>

结果：

还有更长的标题：

Answer 2

试试这个方法，
1. 在你的卡片视图的约束布局中，添加一个方向为水平的LinearLayout。
2. 在该水平视图中，添加带有宽度和高度的标题作为换行上下文。
然后添加 imageview 和 number textview。
3. 将您的详细信息文本视图设置在该线性布局下方。
完成。
