Android RadioGroup中横向、竖向布局RadioButton的问题

转载：http://blog.csdn.net/aminfo/article/details/7558308

RadioGroup默认的横向android:orientation="horizontal"、竖向布局android:orientation="vertical"，无法设置每行显示的个数，只能全部横向显示或者竖向显示。

而通过线性布局模版后，RadioButton却变成不是同一个组的，变成不是单选的，达不到原先想要的效果。

 

本例中是想在RadioGroup中一行显示2个RadioButton，上面的方法行不通，后来发现在RadioButton用android:layout_marginLeft和android:layout_marginTop可能设置RadioButton的相对位置，于是，通过下面代码，实现了一行显示2列RadioButton，目前还未测试在不同分辨率下是否会出现误差。效果图如下：



 

布局代码如下：

通过修改 RadioButton的android:layout_marginLeft和android:layout_marginTop属性实现
