android listview选中某一行，成选中状态颜色高亮显示

把下面的XML文件保存成你自己命名的.xml文件（比如list_bg.xml），注意，这个文件相当于一个背景图片选择器，在系统使用时根据
ListView中的列表项的状态来使用相应的背景图片，什么情况使用什么图片我在下面都进行了说明。还有，你可以把它看成是一个图片来使用，放于
drawable目录下，配置背景属性android:background="@drawable/list_bg"就能达到你需要的目的了。
<?xml version="1.0" encoding="utf-8" ?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android

">
  <item android:state_window_focused="false" 
        android:drawable="@drawable/没有焦点时的图片背景" /> 
  <item android:state_focused="true" android:state_pressed="true" 
        android:drawable=
              "@drawable/非触摸模式下获得焦点并单击时的背景图片" /> 
  <item android:state_focused="false" android:state_pressed="true" 
        android:drawable="@drawable/触摸模式下单击时的背景图片" /> 
  <item android:state_selected="true" 
        android:drawable="@drawable/选中时的图片背景" /> 
  <item android:state_focused="true" 
        android:drawable="@drawable/获得焦点时的图片背景" /> 
</selector> 

----------------------------------------------------------------你可以看下源代码ListView列表项背景的默认实现SDK目录\tools\lib\res\default\drawable\list_selector_background.xml

目标：选中item，其字体设置为#3197FF，未选中的，其字体为#FFFFFF。其效果图如下：

与listvew设置选中行item背景图片一样，使用selector，不过这里的颜色设置，应该是在listview中的textview中设置。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

<?xmlversion="1.0"encoding="utf-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" > <TableRow> <TextView android:id="@+id/name_tv" android:layout_height="wrap_content" android:layout_width="wrap_content" android:textSize="25px" android:textColor="@drawable/itemcolor"> </TextView> </TableRow> </TableLayout>

同样，定义itemcolor.xml文件，修改选中行的字体颜色：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

<?xmlversion="1.0"encoding="utf-8"?> <selectorxmlns:android="http://schemas.android.com/apk/res/android"> <!-- 没有焦点时字体颜色 --> <item android:state_selected="false" android:color="#FFFFFF"/> <!--选中时的字体颜色 --> <item android:state_selected="true" android:color="#3197FF"/> <!-- 非触摸模式下获得焦点并单击时的字体颜色 --> <item android:state_focused="true" android:state_pressed="true" android:color="#3197FF"/> </selector>

完成了。

屏蔽获取焦点时的高亮橙色显示：

listview.setSelector(R.drawable.nocolor);图片为一张无色透明图片即可，或者

android:listSelector="@drawable/nocolor"

构造自己的adapter，在getView中，设置颜色，点击item，刷新listview。
