myhomegrid.xml

<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/gwMenu"

<selector xmlns:android="http://schemas.android.com/apk/res/android">

 <ImageView
 android:id="@+id/icon_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

你应该更正你的选择器，就像这样

<selector xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:state_pressed="true" android:drawable="@drawable/pressedback" />
   <item android:state_focused="true" android:drawable="@drawable/focusedback" />
   <item android:state_selected="true" android:drawable="@drawable/focusedback" />
</selector>

UPD：我的错，您不需要 GridView 的可点击和可聚焦的属性
