It is done via a selector... There is not a lot of documentation about them, the basic premise is that it is an xml file that defines drawables to be used when certain conditions/states are met... such as when something gets focus. It goes in the res/drawable folder just like any other drawable and is referenced the same way.
Here is an example of a selector that I use in one of my apps: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android";> <!-- Focused --> <item android:drawable="@drawable/gallery_selection_red_small" android:state_focused="true" android:state_selected="true" android:state_pressed="true" /> <item android:drawable="@drawable/gallery_selection_orange_small" android:state_focused="true" android:state_selected="true" android:state_pressed="false" /> <item android:drawable="@drawable/gallery_selection_orange_small" android:state_focused="true" android:state_selected="true" android:state_pressed="true" /> <item android:drawable="@drawable/gallery_selection_orange_small" android:state_focused="true" android:state_selected="false" android:state_pressed="true" /> <!-- Not Focused --> <item android:drawable="@drawable/gallery_selection_blue_small" android:state_focused="false" android:state_selected="true" android:state_pressed="false" /> <item android:drawable="@drawable/gallery_selection_red_small" android:state_focused="false" android:state_selected="true" android:state_pressed="true" /> <item android:drawable="@drawable/gallery_selection_red_small" android:state_focused="false" android:state_selected="false" android:state_pressed="true" /> <!-- Default --> <item android:drawable="@drawable/translucent_box" /> </selector> Hope that helps, Justin ---------------------------------------------------------------------- There are only 10 types of people in the world...
