设置listview的item选中背景

代码块

**这里面主要是设置android:choiceMode="singleChoice"这个属性**
<ListView
android:id="@+id/lv_trade"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dip"
android:choiceMode="singleChoice"
android:background="#FFFFFF" >
</ListView>

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@color/white" android:state_activated="false"/>
<item android:drawable="@color/blue" android:state_pressed="true"/>
<item android:drawable="@color/blue" android:state_activated="true"/>
</selector>

listview.setItemChecked(position, true);
