查看关于如何创建一个Android形状和形状适用于您的布局本教程：

Check out this tutorial on how to create an Android shape and apply that shape to your layout: http://www.vogella.com/blog/2011/07/19/android-shapes/

具体使用＆LT;边角＆GT; 的＆LT属性;形状＆GT; 以创建圆角，请参阅例如，从上述参考教程如下：

Specifically you use the <corners> attribute of the <shape> to create rounded corners, see example below from the above referenced tutorial:

<corners 
    android:bottomRightRadius="7dp"
    android:bottomLeftRadius="7dp" 
    android:topLeftRadius="7dp" 
    android:topRightRadius="7dp"
/>

更新2 - 这为我工作：

绘制，华电国际/ rounded.xml：

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

    <stroke android:width="2dp" android:color="#FFFFFFFF" />

    <corners 
        android:bottomRightRadius="7dp" 
        android:bottomLeftRadius="7dp" 
        android:topLeftRadius="7dp" 
        android:topRightRadius="7dp"/> 

    <solid android:color="#00000000" />

</shape>

绘制，华电国际/ solid.xml：

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

    <stroke android:width="2dp" android:color="#FFFFFFFF" />

    <solid android:color="#00000000" />

</shape>

绘制，华电国际/ rounded_inside_corners.xml：

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

    <item android:drawable="@drawable/rounded" />
    <item android:drawable="@drawable/solid" /> 

</layer-list>

结果
然后在我的活动布局：

Then in my activity layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/my_shape"
    tools:context=".CameraActivity" >

    <SurfaceView
        android:id="@+id/surfaceView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/rounded_inside_corners"
        android:layout_above="@+id/linearLayout1" />

    <FrameLayout
        android:id="@+id/linearLayout1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/buttonTakePicture"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_gravity="center_horizontal"
            android:background="@drawable/camera_click_256"
            android:gravity="center_horizontal" />
    </FrameLayout>

</RelativeLayout>

结果
