Why can't set background of checked ListView item?

I'm using SherlockListFragment to show list items, and I want to set the background of list item highlighted when it is checked. But after I did all the things below, the list item background still remain unchanged when set checked (but it changes when clicked). Why?
The list selector => drawable/list_selector.xml:
<?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="#color/transparent" />
<item android:state_focused="true" android:state_enabled="false"
android:state_pressed="true"
android:drawable="#drawable/list_selector_background_dark" />
<item android:state_focused="true" android:state_enabled="false"
android:drawable="#drawable/list_selector_background_dark" />
<item android:state_focused="true" android:state_pressed="true"
android:drawable="#drawable/list_selector_background_dark" />
<item android:state_focused="false" android:state_pressed="true"
android:drawable="#drawable/list_selector_background_dark" />
<item android:state_checked="true"
android:drawable="#drawable/list_selector_background_dark" />
</selector>
The list item layout => layout/list_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="5dip"
android:background="#drawable/list_selector_dark">
......
</RelativeLayout>
The fragment layout => layout/fragment_list.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#id/android:list"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:layout_gravity="start"
android:scrollbars="none"
android:fastScrollEnabled="true"
android:choiceMode="singleChoice"
android:listSelector="#drawable/list_selector_dark" />
<TextView
android:id="#id/android:empty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="#string/no_entry" />
</LinearLayout>

Change listview row item background color and text color in android

In my custom listview, I have used relativelayout and inside that added 2 textviews vertically.
Background image is set to relativelayout. Now I want to change background image as well as textcolor of textview when listview item is pressed.
How to do this, any one have idea?

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/item_bg"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text=""
android:textColor="#color/orange"
android:textSize="18sp"
android:textStyle="bold"
android:layout_marginTop="10dip"
android:layout_marginLeft="10dip"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:layout_marginRight="20dip"
android:layout_marginTop="8dip"
android:ellipsize="end"
android:maxLines="3"
android:duplicateParentState="true" <!-- this is a line to use..-->
android:textColor="#color/_textcolor"
android:textSize="14sp" >
</TextView>
item_bg.xml inside res/drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:drawable="#drawable/bannerbg_hover"/>
<item android:state_focused="true" android:drawable="#drawable/bannerbg_hover" />
<item android:state_selected="true" android:drawable="#drawable/bannerbg_hover"/>
<item android:drawable="#drawable/bannerbg"/>
</selector>
_textcolor.xml inside res/color/ folder:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:color="#color/white"/>
<item android:state_focused="true" android:color="#color/white" />
<item android:state_selected="true" android:color="#color/white"/>
<item android:color="#color/dark_blue"/>
</selector>

Concerning the background, you should create a StateList Drawable and set it as the background of your rows.
Ex of a such drawable (could be named background_selector.xml) :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#color/color1" /> <!-- pressed -->
<item android:drawable="#color/color2" /> <!-- default -->
</selector>
And in the layout declaration of your row :
...
android:background="#drawable/background_selector"
...
Use the same way for your text with the Color State List

My ListView background selector won't highlight the selected row

I used this SO question as a guide, but when I click a row it doesn't stay highlighted. What is wrong with my code?
score_list.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/score_list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/keyboard"
android:listSelector="#drawable/selector"
android:choiceMode="singleChoice"
android:divider="#CCCCCC"
android:dividerHeight="1dp"
android:paddingLeft="15dp"
android:paddingRight="15dp" />
...
</RelativeLayout>
drawable/selector.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:drawable="#color/highlight"/>
<item android:state_pressed="true" android:drawable="#color/highlight"/>
</selector>
score_row_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scoreRowLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:background="#drawable/row_selector" >
...
</LinearLayout>
drawable/row_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true" android:drawable="#color/highlight" />
<item android:state_activated="true" android:drawable="#color/highlight" />
<item android:drawable="#color/transparent" />
</selector>
This code now works properly.

Try to use state_activated for your row_selector.

Change Listview item item textcolor

Hi I am using listview which have multiple items adding dynamically..
I want to change the text color of listitem any idea
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#659EC7">
<ImageView android:id="#+id/icon" android:layout_width="72px"
android:layout_height="wrap_content"
android:layout_marginTop="5px" />
<TwoLineListItem xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingTop="5px"
android:paddingBottom="5px">
<TextView android:id="#+id/item1" android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView android:id="#+id/item2" android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:paddingTop="30px" />
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:background="#android:color/darker_gray"/>
</TwoLineListItem>
</LinearLayout>
I am using 2linelistIem

Here is the code I wrote and used:
It keeps the android style for all other states. it just overlays the transparent state with your desired color:
Layer list drawable for list view with custom background
as you can see in my question there is a minor bug with the focused state, but it is still the best solution i ever saw :D

Use this type of technique to change the color dynamically:
<?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/black" /> <!-- focused -->
<item android:state_focused="true" android:state_pressed="true" android:drawable="#color/black" /> <!-- focused and pressed-->
<item android:state_pressed="true" android:drawable="#color/green" /> <!-- pressed -->
<item android:drawable="#color/black" /> <!-- default -->
</selector>

I want it change background menu_content_hover when user press on items and selected ,change backround menu_content when user scroll list(unselected) or choose another items.I used simpleCursorAdapter. Any Help? Thanks for all your help.

The selector should be like this:
<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>
