我有 lst_custom_view.xml
文件 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top|left"
android:background="@drawable/list_choose"
android:orientation="horizontal">
<TextView
android:id="@+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_gravity="center"
android:layout_marginLeft="20dp"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true"
android:textColor="#ff000000"
android:textSize="22dp" />
</RelativeLayout>
Main.xml
中的Listview<ListView
android:id="@+id/lstView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_weight="1"
android:background="@android:color/transparent"
android:cacheColorHint="@android:color/transparent"
android:divider="@drawable/menu_phancach"
android:dividerHeight="2dp"
android:visibility="visible">
</ListView>
我使用Selector with Relativelayout的背景,名称为 list_choose.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_selected="false"
android:state_pressed="false"
android:drawable="@drawable/menu_content" />
<item android:state_selected="true"
android:state_pressed="false"
android:drawable="@drawable/menu_content_hover" />
<item android:state_pressed="true"
android:drawable="@drawable/menu_content_hover" />
</selector>
当我按项目列表视图但未选择背景menu_content_hover时,它会显示RelativeLayout menu_content_hover的背景。我希望它在用户按下项目和选择时更改背景menu_content_hover,在用户滚动列表(未选中)时更改背景menu_content或选择其他项目。我使用simpleCursorAdapter。任何帮助?谢谢你的帮助。
答案 0 :(得分:0)
选择器应该是这样的:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="@drawable/background_pressed" />
<item android:state_focused="true"
android:drawable="@drawable/background_focused" />
<item android:state_selected="true"
android:drawable="@drawable/background_selected" />
<item android:drawable="@drawable/background_default"/>
</selector>
