问题描述

我需要为我的单选按钮创建 2 个环形:

I need to create 2 ring shapes for my radio buttons:

白色圆圈
白色圆圈内有另一个不同颜色的圆圈

我没有太多关于如何做到这一点的线索.到目前为止我尝试了什么:

I dont have much clue on how to do this. What I tried so far:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_checked="false"><shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="ring">
            <android:solid android:color="@color/white" />

            <android:size android:height="10dp" android:width="10dp" />

            <corners android:radius="10dp" />
        </shape></item>

</selector>

<RadioButton
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:button="@drawable/radio_shape_unchecked"
                        android:checked="false"
                        android:text="Persoana fizica" />
