代码实现：

1.button_normal.xml

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

    <solid android:color="#ff007aff" />

    <corners
        android:bottomLeftRadius="6dp"
        android:bottomRightRadius="6dp"
        android:topLeftRadius="6dp"
        android:topRightRadius="6dp" />

</shape>

2.button_select.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="#FFD700" />

    <corners
        android:bottomLeftRadius="6dp"
        android:bottomRightRadius="6dp"
        android:topLeftRadius="6dp"
        android:topRightRadius="6dp" />

</shape>

solid：实心，就是填充的意思

corners：圆角
android:radius为角的弧度，值越大角越圆。

3.button_selector.xml

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

    <item android:drawable="@drawable/button_select" android:state_focused="true"></item>
    <item android:drawable="@drawable/button_select" android:state_pressed="true"></item>
    <item android:drawable="@drawable/button_normal" android:state_focused="false" android:state_pressed="false"></item>
    <item android:drawable="@drawable/button_normal" ></item>

</selector>

4.fragment_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.jjc.demo.MainActivity$PlaceholderFragment" >

    <Button
        android:id="@+id/button_test"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/button_selector"
        android:text="推荐组合"
        android:textColor="@android:color/white" />

</RelativeLayout>
