android - 对于约束布局android，屏障没有按预期运行
问题描述
期待实现这一目标
对应的XML是这个

但是，当内容destText或srcText溢出时barrier_top_strip并不能阻止它导致
我究竟做错了什么？
PS：款式供参考
<style name="TextLabelArbitrage">
<item name="android:layout_width">0dp</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:fontFamily">@font/medium</item>
<item name="android:gravity">center</item>
<item name="android:textSize">10sp</item>
<item name="android:paddingTop">@dimen/margin_atomic</item>
</style>
<style name="TextContentArbitrage">
<item name="android:layout_width">0dp</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:fontFamily">@font/medium</item>
<item name="android:gravity">center</item>
<item name="android:maxLines">2</item>
<item name="android:ellipsize">end</item>
<item name="android:textSize">16sp</item>
<item name="android:paddingBottom">@dimen/margin_atomic</item>
</style>
解决方案
destText将和的高度更改srcText为0dp。他们现在wrap_content。此更改应将它们的垂直高度限制在您期望的范围内。
