最近在做一个项目，里边的设置页面要求圆角选项，类似QQ浏览器中的设置页面。废话不多说，上图看看大致效果：

 做出这种效果，需要在drawable中加入四个selector（单个圆角选项、圆角上、圆角中部、圆角下）和一个shape（多个圆角选项外框）。

注意：

1、如果没有在代码中做setOnClickListener处理，想看到效果，需要加上android:clickable="true"属性，否则点击没有效果。

2、圆角选项外框的LinearLayout需要加上android:padding="1dp"属性，否则框内的选项会遮盖圆角框，就看不到外部边框了。

3、在圆角上、圆角下的selector中，获得焦点时的圆角角度比默认时偏小些，不然会有点空白情况发生。

下面是代码时间：

1、单个圆角选项：option_setting_bg_full.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- 点击时 -->
    <item android:state_pressed="true">
        <shape>
            <solid android:color="@color/mine_option_bg_pre" />

            <corners android:radius="5dp" />

            <stroke android:width="1dp" android:color="#afafaf" />
        </shape>
    </item>
    <!-- 获得焦点时 -->
    <item android:state_focused="true">
        <shape>
            <solid android:color="@color/mine_option_bg_pre" />

            <corners android:radius="5dp" />

            <stroke android:width="1dp" android:color="#afafaf" />
        </shape>
    </item>
    <!-- 默认状态 -->
    <item>
        <shape>
            <solid android:color="@color/mine_option_bg_nor" />

            <corners android:radius="5dp" />

            <stroke android:width="1dp" android:color="#afafaf" />
        </shape>
    </item>

</selector>

2、多个圆角选项外框：option_setting_bg_all.xml

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

    <solid android:color="@color/mine_option_bg_nor" />

    <corners 
        android:topLeftRadius="5dp"
        android:topRightRadius="5dp"
        android:bottomLeftRadius="5dp"
        android:bottomRightRadius="5dp" />

    <stroke
        android:width="1dp"
        android:color="#afafaf" />

</shape>

3、圆角上：option_setting_bg_top.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <!-- 点击时 -->
    <item android:state_pressed="true">
        <shape>
            <solid android:color="@color/mine_option_bg_pre" />

            <corners 
                android:topLeftRadius="4dp" 
                android:topRightRadius="4dp"

                 android:bottomRightRadius="0dp" />

            <stroke 
                android:width="0dp" 
                android:color="#afafaf" />
        </shape>
    </item>
    <!-- 获得焦点时 -->
    <item android:state_focused="true">
        <shape>
            <solid android:color="@color/mine_option_bg_pre" />

            <corners 
                android:topLeftRadius="4dp" 
                android:topRightRadius="4dp"
                android:bottomLeftRadius="0dp"
                 android:bottomRightRadius="0dp" />

            <stroke 
                android:width="0dp" 
                android:color="#afafaf" />
        </shape>
    </item>
    <!-- 默认状态 -->
    <item>
        <shape>
            <solid android:color="@color/mine_option_bg_nor" />

            <corners 
                android:topLeftRadius="5dp" 
                android:topRightRadius="5dp"
                android:bottomLeftRadius="0dp"
                 android:bottomRightRadius="0dp" />

            <stroke android:width="0dp" android:color="#afafaf" />
        </shape>
    </item>
</selector>

4、圆角中部：option_setting_bg_center.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <!-- 点击时 -->
    <item android:state_pressed="true">
        <shape>
            <solid android:color="@color/mine_option_bg_pre" />

            <corners android:radius="0dp"/>

            <stroke android:width="0dp" android:color="#afafaf" />
        </shape>
    </item>
    <!-- 获得焦点时 -->
    <item android:state_focused="true">

        </shape>
    </item>
    <!-- 默认状态 -->
    <item>
        <shape>
            <solid android:color="@color/mine_option_bg_nor" />

            <corners android:radius="0dp"/>

            <stroke android:width="0dp" android:color="#afafaf" />
        </shape>
    </item>
