使用 RadioGroup/RadioButton 对齐文本 [英] Aligning Text with a RadioGroup/RadioButton

问题描述

我想在 RadioGroup 旁边添加文本，作为它的一种标签.所以 RadioGroup 中有两个带有文本的按钮，目前，我只能让顶部对齐，但这看起来很尴尬.我可以尝试将 TextView 边距对齐，但这并不理想或容易.RadioGroup 和 TextView 生活在一个 RelativeLayout 中，我已经尝试 android:layout_alignBaseline 使用 RadioGroup 和 RadioButtons 之一为 TextView，但似乎 RadioGroup 没有基线，我似乎无法从 TextView 获取 RadioButton 的基线.

I would like to have text next to a RadioGroup that is a sort of label for it. So there are two buttons in the RadioGroup with text to them, and currently, I can only get the tops to align, but that looks pretty awkward. I can try to margin the TextView in line but that's not ideal or easy. The RadioGroup and TextView live inside a RelativeLayout, I've tried android:layout_alignBaseline for the TextView with the RadioGroup and one of the RadioButtons, but it doesn't seem that the RadioGroup has a baseline, and I can't seem to get the baseline for the RadioButton from the TextView.

推荐答案

这几天我也遇到了同样的问题，我终于解决了.我尝试了我想到的所有组合，最后我发现诀窍是将 android:layout_weight 与 TextViews 上的值相同.这将它们对齐在 RadioButtons 的中心.

I had the same problem these days and I finally solved it. I tried every combination that came on my mind and in the end I figure it out that trick is in putting android:layout_weight with a same value on TextViews. That aligns them just on the center of RadioButtons.
