you should go "menu->Project->clean" and let eclipse clean your project.
the android R files are then rebuilt so everything should be fine afterwards.

cheers

I'll toss out what works for me. The first thing I see is that I use ImageButton instead of just Button

<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android";>
<item android:state_window_focused="false" android:state_enabled="true"
android:drawable="@drawable/about_btn_normal" />
<item android:state_window_focused="false" android:state_enabled="false"
android:drawable="@drawable/about_btn_normal" />
<item android:state_pressed="true"
android:drawable="@drawable/about_btn_pressed" />
<item android:state_focused="true" android:state_enabled="true"
android:drawable="@drawable/about_btn_pressed" />
<item android:state_enabled="true"
android:drawable="@drawable/about_btn_normal" />
<item android:state_focused="true"
android:drawable="@drawable/about_btn_normal" />
<item android:drawable="@drawable/about_btn_normal" /> </selector>

* *<ImageButton
         android:layout_gravity="center"
         android:id="@+id/continue_button"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:adjustViewBounds="true"
android:background="#0c3d97" android:src="@drawable/start_btn"
    android:onClick="startGame"
          />

    I am getting an error from Eclipse when I use this xml file (res/
    drawable/btnswitch.xml) to designate different button conditions

    <?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/btn_st_rd" /> <!-- pressed -->
        <item android:state_focused="true"
              android:drawable="@drawable/btn_st_gr" /> <!-- focused -->
        <item android:drawable="@drawable/btn_st_gr" /> <!-- default -->
        </selector>

    I call it in my layout file with this code:

           <Button
           android:id="@+id/startTimer_btn"
           android:src="@drawable/btnswitch""
           android:layout_width="wrap_content"
           android:layout_height="fill_parent"


           />

    Eclipse says it can't run the configuration because I have errors but
    does not show any errors. And when I remove the xml code (to go back
    to my original code which just sets a background image for the Button)
    it says that now has errors. I have to restart Eclipse to get the
    original code to run again.

    Any ideas as to what I am missing?
