Answer 1

Set this tow attributes for your view items :

1. android:focusableInTouchMode="true"
2. android:background="@drawable/bg_view"

where bg_view.xml is :

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true">
    <shape android:shape="rectangle">
        <stroke android:width="2dp" android:color="@android:color/white" />
        <solid android:color="#1F1F3E" />
    </shape>
</item>
<item>
    <shape>
        <solid android:color="#1F1F3E" />
    </shape>
</item>
