我创建了一个简单的Android滑动菜单,问题是当我点击它时项目颜色不会改变。
这是我的xml资源:
list_item_bg_pressed.xml:(在Drawable下)
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient
android:startColor="@color/list_background_pressed"
android:endColor="@color/list_background_pressed"
android:angle="90" />
</shape>
list_item_bg_normal.xml:(在Drawable下)
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="@color/menubg"
android:endColor="@color/menubg"
android:angle="90" />
</shape>
列表selector.xml:(在Drawable下)
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/list_item_bg_normal" android:state_activated="false"/>
<item android:drawable="@drawable/list_item_bg_pressed" android:state_pressed="true"/>
<item android:drawable="@drawable/list_item_bg_pressed" android:state_activated="true"/>
</selector>
activity_main.xml:(在布局下)
<com.example.app.MainLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/drawer_layout"
>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/menu_listview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="@color/menubg"
android:cacheColorHint="#00000000"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:listSelector="@drawable/list_selector"
android:divider="@color/list_divider"
android:dividerHeight="1dp"
>
</ListView>
</LinearLayout>
答案 0 :(得分:1)
将您的选择器更改为:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_selected="false"
android:state_focused="false"
android:state_pressed="false"
android:drawable="@drawable/list_item_bg_normal" />
<item
android:state_pressed="true"
android:drawable="@drawable/list_item_bg_pressed" />
<item
android:state_selected="true"
android:state_focused="false"
android:state_pressed="false"
android:drawable="@drawable/list_item_bg_pressed" />
</selector>
恢复:你将拥有几种状态,并且可以使用它们,你可以获得所需的效果。
