in getView

if(position == focusedPosition) {
    textView.setColor(context.getResources().getColor(R.color.color_for_focused_item);
} else {

}

Answer 3

Add an xml file to manage the background of the LinearLayout.

list_bg_selector.xml :

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

    <!-- Active tab -->
    <item android:state_selected="true" android:state_focused="false"
        android:state_pressed="false" android:drawable="@drawable/list_selected_bgimage" />
    <!-- Inactive tab -->
    <item android:state_selected="false" android:state_focused="false"
        android:state_pressed="false" android:drawable="@drawable/list_default_bgimage" />
    <!-- Pressed tab -->
    <item android:state_pressed="true" android:drawable="@drawable/list_selected_bgimage" />
    <!-- Selected tab (using d-pad) -->
    <item android:state_focused="true" android:state_selected="true"
        android:state_pressed="false" android:drawable="@drawable/list_selected_bgimage" />
</selector> 

To manage the text color, set the text color to another xml.

text_selector.xml:

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

    <item android:state_selected="true" android:color="@android:color/black"/>
    <item android:state_focused="true" android:color="@android:color/black"/>
    <item android:state_pressed="true" android:color="@android:color/black"/>
    <item android:color="@android:color/white"/>

</selector>
