Android GridView选择的项目背景

Question

我的GridView未显示按下并聚焦选择器我的代码在下面。

myhomegrid.xml

<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/gwMenu"
android:layout_width="fill_parent" 
android:layout_height="fill_parent"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:columnWidth="90dp"
android:stretchMode="columnWidth"
android:gravity="center" 
android:drawSelectorOnTop="true"
android:listSelector="@layout/grid_selector"

     />

grid_selector.xml

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

menu.xml文件

<LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/widget44"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:orientation="vertical"
android:layout_x="201px"
 android:layout_y="165px"
 android:gravity="center_horizontal">
 <ImageView
 android:id="@+id/icon_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
 </ImageView>
<TextView
android:id="@+id/icon_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
android:gravity="center_horizontal"
android:textColor="#ffffff"
android:textColorHighlight="#656565">
</TextView>
</LinearLayout>

聚焦图像

按下图像

我想像下面的图像一样分离：

Answer 1

您应该将grid_selector.xml放在drawable文件夹中，然后通过以下方式引用它：

android:listSelector="@drawable/grid_selector"

Answer 2

您应该更正您的选择器，例如

<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：我的不好，你不需要GridView的可点击和可聚焦的属性
