android - Refrencing a selector drawable from a style results blank imagebutton -

i want have imagebuttons changing image based on state. (same "like" button in 9 gag , facebook apps).

i have defined style each of them references selector drawable when run program, images doesn't appear. can tell me what's wrong approach? (sorry bad english)

comment_actions_style in values folder:

    <style name="likestyle">         <item name="android:src">@drawable/like</item>     </style>      <style name="dislikestyle">         <item name="android:src">@drawable/dislike_normal</item>     </style>      <style name="replystyle">         <item name="android:src">@drawable/reply_normal</item>     </style>      <style name="sharestyle">         <item name="android:src">@drawable/share</item>     </style> </resources> 

and drawable in drawable folder: (other buttons same)

<selector xmlns:android="http://schemas.android.com/apk/res/android">      <item android:drawable="@drawable/like_clicked" android:state_pressed="true"/>  <!-- pressed -->     <item android:drawable="@drawable/like_focused" android:state_focused="true"/>  <!-- focused -->     <item android:drawable="@drawable/like_normal"/>  <!-- default -->  </selector> 

edit:
forgot mention, have list view items user comments , comments have buttons described above.

here items layout (part of it)

<linearlayout     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:layout_below="@id/comment_content"     android:orientation="horizontal"     >      <include         android:id="@+id/like"         android:layout_width="0dp"         android:layout_weight="1"         android:layout_height="wrap_content"         layout="@layout/comment_actions"         style="@style/likestyle" /> </linearlayout> 

and comment_actions layout:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/comment_action"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:paddingbottom="5dip">         <imagebutton             android:id="@+id/comment_action_img"             android:layout_width="40dp"             android:layout_height="40dp"             android:background="@android:color/transparent"             />         <textview              android:id="@+id/comment_action_num"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_torightof="@id/comment_action_img"             android:gravity="center"             android:layout_marginleft="5dip"/>  </relativelayout> 

these buttons inherit layout if that's matter.

here, setting style comment_actions layout, , relative layout, won't abled response "android:src" attribute.

<linearlayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/comment_content" android:orientation="horizontal" >  <include     android:id="@+id/like"     android:layout_width="0dp"     android:layout_weight="1"     android:layout_height="wrap_content"     layout="@layout/comment_actions"     style="@style/likestyle" /> <!--here,you setting style relativelayout --> </linearlayout>
