`我正在使用列表选择器，但它不能正常工作。单击列表项后我得到效果，但在单击项目之前没有效果。这是我的选择器代码：

<?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/ic_launcher" />

    <item android:state_pressed="true"
        android:drawable="@drawable/headerplain" />

    <item 
    android:state_focused="true" 
    android:state_pressed="false" 
    android:drawable="@drawable/headerplain" />

    <item android:state_selected="true"
     android:state_pressed="false"
        android:drawable="@drawable/headerplain" />
</selector>

and I have applied it to listView as 
 <ListView
        android:id="@+id/listView123"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"         
        android:listSelector="@drawable/list_selector"
        android:drawSelectorOnTop="true"
        android:focusable="true"
        >
    </ListView>

请帮我解决这个问题提前谢谢
