首先radiogroup的布局，重要的是设置radiogroup的三个属性

android:background="@drawable/selector_speed_borrow_select_day"                                    android:button="@null"                                    android:textColor="@color/selector_select_day"

radiogroup的布局

     <RadioGroup                                android:id="@+id/radiogroup_select_day"                                android:layout_width="match_parent"                                android:layout_height="80px"                                android:layout_gravity="center_vertical"                                android:gravity="center_vertical|right"                                android:orientation="horizontal">                                <RadioButton                                    android:id="@+id/radiobtn_fifteen"                                    android:layout_width="170px"                                    android:layout_height="70px"                                    android:layout_marginRight="40px"                                    android:background="@drawable/selector_speed_borrow_select_day"                                    android:button="@null"                                    android:gravity="center"                                    android:text="15天"                                    android:textColor="@color/selector_select_day" />                                <RadioButton                                    android:id="@+id/radiobtn_thirty"                                    android:layout_width="170px"                                    android:layout_height="70px"                                    android:background="@drawable/selector_speed_borrow_select_day"                                    android:button="@null"                                    android:gravity="center"                                    android:text="30天"                                    android:textColor="@color/selector_select_day" />                            </RadioGroup>

点击背景改变的selector文件
在res/drawable中selector_speed_borrow_select_day.xml，如果背景是图片的话直接可以用图片，如果背景是shape文件

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <!-- 默认时的背景 -->    <item android:drawable="@drawable/shape_gradient_white_stroke_blue" android:state_checked="false"/>    <!-- 选择时的背景 -->    <item android:drawable="@drawable/shape_gradient_blue" android:state_checked="true"/></selector>

背景为shape文件
默认时的背景文件shape_gradient_white_stroke_blue.xml

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android"    android:shape="rectangle"    android:color="@color/white"    >    <stroke        android:dashGap="0.0dip"        android:dashWidth="0.0dip"        android:width="1px"         android:color="@color/text_blue"      />    <solid android:color="@color/white" />    <corners       android:radius="120px"        /></shape>

选中时的背景文件shape_gradient_blue.xml

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android"    android:shape="rectangle"    android:color="@color/text_blue"    >    <solid android:color="@color/text_blue" />    <corners      android:radius="120px"        />    <stroke        android:dashGap="0.0dip"        android:dashWidth="0.0dip"        android:width="1px"        android:color="@color/text_blue"        /></shape>

点击按钮文字变颜色的效果，首先在res下新建一个color文件
这里写图片描述
创建selector文件selector_select_day.xml

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:state_checked="true" android:color="@color/white"/>    <!-- not selected -->    <item android:color="@color/text_blue"/></selector>

至此大功告成
