I'm working on an android keyboard application. As you know key object can set an icon or label for itself , so now I wanna set a re-sizable rounded rectangle for space keyboard button like This one

I wanna make it able to be resized when it's running on large screens , I have this in my keyboard xml class :

<Key android:codes="46" android:keyIcon = "@drawable/space_button_drawable.xml">

what should I have in my space_button_drawable.xml ?

EDIT 1 :

buttonbgselector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_pressed="false"
        android:drawable="@drawable/button" />
    <item
        android:state_pressed="true"
        android:drawable="@drawable/button2" />
</selector>

keyboard.xml

    <?xml version="1.0" encoding="UTF-8"?>
<android.inputmethodservice.KeyboardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/keyboard"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:keyBackground="@drawable/buttonbgselector"
    android:keyPreviewLayout ="@layout/preview" />

space_button_drawable.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners
        android:radius="10dp" />
    <solid
        android:color="#AAA" />
</shape>

use this drawable in your background of LinearLayout keyboard.xml
