Android drawable shape : make Rectangle into a Square

Question

I'm trying to define a nice rounded corner square shape in Android, but I can only get a nice rounded corner rectangle.

My xml in /res/drawable looks like this:

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

<item android:state_pressed="true" 
      app:state_playing = "true" >
    <shape>
        <stroke
            android:width="2dp"
            android:color="@color/red" />
        <corners
            android:radius="3dp" />
        <padding
            android:left="10dp"
            android:top="10dp"
            android:right="10dp"
            android:bottom="10dp" />
        <solid 
            android:color="@color/blue" />
        <size
            android:width="3dp"
            android:height="3dp" />
    </shape>        
</item>
</selector>

And all works fine except

<size android:width="3dp" android:height="3dp" />

Which I'd have hoped made the thing square, but no such luck.

My layout looks like this:

 <?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/grid8x8"
    android:gravity="center"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

<uk.co.alexlydiate.sequencer.Key  android:background="@drawable/key"        
    android:id="@+id/keyA1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:layout_weight="1"  android:layout_margin="2px"
/>
<uk.co.alexlydiate.sequencer.Key  android:background="@drawable/key"        
    android:id="@+id/keyA2"
    android:layout_below="@+id/keyA1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:layout_weight="1"  android:layout_margin="2px"
/>
</RelativeLayout>

Anybody got any bright ideas? Thanks!

AFAIK: shapes stretch themselves according to the View 's layout. Instead you can define the Square View and set shape background.

OR

Use an Image as background
