투명도가없는 Android 갤러리 비 선택 항목

Question

갤러리의 모든 항목을 투명하지 않고 "단색"으로 유지할 수 있습니까? StateListDrawable을 사용하여 시도했지만 여전히 선택되지 않은 항목에 투명도를 제공합니다.

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

    <item android:drawable="@color/card_background" android:state_focused="true"/> 
    <item android:drawable="@color/card_background" android:state_pressed="true"/> 
    <item android:drawable="@color/card_background" android:state_active="true"/> 
    <item android:drawable="@color/card_background" android:state_selected="true"/> 
    <item android:drawable="@color/card_background" android:state_enabled="true"/> 
    <item android:drawable="@color/card_background" android:state_window_focused="true"/> 
    <item android:drawable="@color/card_background" android:state_focused="false"/> 
    <item android:drawable="@color/card_background" android:state_pressed="false"/> 
    <item android:drawable="@color/card_background" android:state_active="false"/> 
    <item android:drawable="@color/card_background" android:state_selected="false"/> 
    <item android:drawable="@color/card_background" android:state_enabled="false"/> 
    <item android:drawable="@color/card_background" android:state_window_focused="false"/> 
    <item android:drawable="@color/card_background"/> 

</selector>
