需要创建带圆角的背景

Question

I want to create background with rounded corners, but inside should be transparent and outside should be white.

Its background for camera view but I cant combine those shapes.

Issue is that I cant combine rectangle with rounded corners and solid block shape.

rounded corner xml

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

    <stroke android:width="4dp" android:color="@color/white" />

    <corners
        android:bottomRightRadius="@dimen/corner_radius_2"
        android:bottomLeftRadius="@dimen/corner_radius_2"
        android:topLeftRadius="@dimen/corner_radius_2"
        android:topRightRadius="@dimen/corner_radius_2"/>

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

</shape>

outer background xml

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

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

</shape>

final background:

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

    <item android:drawable="@drawable/rounded_corner_background" />
    <item android:drawable="@drawable/outer_background" />

</layer-list>
