Mask layout with rounded corner xml shape

Question

I have this LinearLayout:

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <ImageView
        android:layout_width="100dp"
        android:layout_height="70dp"
        android:src="@drawable/ic_launcher"
        android:scaleType="centerCrop"/>

    <TextView
        android:layout_width="100dp"
        android:layout_height="30dp"
        android:background="#FFD800"
        android:textColor="@android:color/black"
        android:gravity="center"
        android:text="Text View"/>
</LinearLayout>

And I want to mask it with rounded corner, like this:

I tried to put it in a FrameLayout with another layout with shape.xml on top of it,

But the most I got was:

or

I'm looking for a way to use shape.xml background,

But with transparent inside the border, and white color outside.

My shape.xml:

<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid
    android:color="#FFFFFF">
</solid>

<stroke
android:width="2dp"
android:color="#000000" >
</stroke>

<padding
    android:left="5dp"
    android:top="5dp"
    android:right="5dp"
    android:bottom="5dp">
</padding>

<corners
    android:radius="50dp">
</corners>
</shape>

Answer 1

make your layout background like this: android:background="@drawable/shape"

Answer 2

Just remove <solid> tag from your shape. Then apply that shape to the background of your LinearLayout.

Because the <solid> tag specifies the fill color of your shape. Without that tag the center of your shape will be fully transparent. So it will look just like a border.

Answer 3

Create a nine-patch with white rounded corners outside, transparent in the middle, ("inverse nine-patch") and put it on top on your LinearLayout. This is a common practice.

Answer 4

Tried out below xml file

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

    <stroke
        android:width="1dp"
        android:color="#4a6176" />

    <padding
        android:left="10dp"
        android:right="10dp"
         />

    <corners android:radius="6dp" />

</shape>
