设置listview中记录的背景色_Android

设置listview中记录的背景色，在线等
main.xml中，设置中android:listSelector 如下

<ListView
android:id="@+id/listView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="false"
android:scrollbars="vertical"
android:background="#eeeeee"
android:divider="#aaaaaa"
android:listSelector="@drawable/listitem_bk"
android:dividerHeight="1px"/>

listitem_bk.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:drawable="@color/red"></item>
<item android:state_pressed="true" android:drawable="@color/red"></item>
</selector>

现问：1 为什么点击listview中记录时，颜色没变化
2 怎么设置点击listview记录时，此记录背景色变为红色，
thanks

Java code

    /**     * 点击listView     *///    private void listviewOnClick(){//        listview.setOnItemClickListener(new OnItemClickListener() {//            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,//                    long arg3) {//                // TODO Auto-generated method stub//                String app=listviewAdataper.getItem(arg2).toString();//                //跳转画面//                Intent intent=new Intent(AdjoiningActivity.this,SpeakActivity.class);//                SpeakActivity.retrunActivity=AdjoiningActivity.class;//                //传递登录id//                Bundle bundle=new Bundle();//                bundle.putString("App", app);//                bundle.putString("loginidid", idd);//                intent.putExtras(bundle);//                startActivity(intent);//                AdjoiningActivity.this.finish();//            }//        });//    }

不是在ListView处设置，我是这样处理的：
(main.xml)
<ListView 
android:id="@+id/content"  
android:layout_width="fill_parent"   
android:layout_height="wrap_content"  
/>  
(listviewitem.xml)
<LinearLayout 
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" 
	android:layout_width="fill_parent" 
	android:layout_height="wrap_content"
	android:background="#ffffff"        
	>  
	<LinearLayout 
	    android:orientation="vertical" 
	    android:layout_width="fill_parent" 
	    android:layout_height="fill_parent"
	    android:background="@drawable/listview_selected"       
	    android:padding="1dp" 
	> 
	<TextView 
	    android:id="@+id/bookname"   
	    android:layout_width="fill_parent"  
	    android:layout_height="wrap_content"  
	    android:textSize="20px" 
	    android:textColor="#000000" 
	    />  
	</LinearLayout>
</LinearLayout>
(/drawable/listview_selected.xml)
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
   <item android:state_pressed="true" android:drawable="@drawable/backgroudui"/>
</selector>

此上，backgroudui是一张图片，如楼主所需，处理为一张红色背景的图片即可,
还有ListView使用适配器的代码就不贴上了，Layout部分代码已全.
