You can copy the drawables used by the Android OS into your project and use them in your state-list drawable. You can find the images in {android-sdk-directory}/platforms/android-##/data/res/drawable[-*dpi]
EDIT:
If you go to {android-sdk-directory}/platforms/android-##/data/res/values
, you'll find the themes.xml
and styles.xml
files used by Android. Using them you can figure out which drawables you'll be looking for.
For example, the default theme on newer versions of Android is Theme.Holo
. This theme has a default style for ImageButtons declared like so:
<item name="imageButtonStyle">@android:style/Widget.Holo.ImageButton</item>
In styles.xml
, this style is defined as follows:
<style name="Widget.Holo.ImageButton" parent="Widget.ImageButton">
<item name="android:background">@android:drawable/btn_default_holo_dark</item>
</style>
Thankfully the background attribute is right there defined in plain sight. Sometimes it's inherited from a parent style and you have to find that instead. In any case, here's the drawable (found in the /drawable
directory since it's xml):
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_window_focused="false" android:state_enabled="true"
android:drawable="@drawable/btn_default_normal_holo_dark" />
<item android:state_window_focused="false" android:state_enabled="false"
android:drawable="@drawable/btn_default_disabled_holo_dark" />
<item android:state_pressed="true"
android:drawable="@drawable/btn_default_pressed_holo_dark" />
<item android:state_focused="true" android:state_enabled="true"
android:drawable="@drawable/btn_default_focused_holo_dark" />
<item android:state_enabled="true"
android:drawable="@drawable/btn_default_normal_holo_dark" />
<item android:state_focused="true"
android:drawable="@drawable/btn_default_disabled_focused_holo_dark" />
<item
android:drawable="@drawable/btn_default_disabled_holo_dark" />
</selector>
So those are the drawables Android uses for the background of a standard ImageButton in the default (holo dark) theme.
