Accessing elements of a widget from the AppWidgetProvider
<p>I have built a widget that contains an ImageButton. </p>

<p>How can I access the imagebutton from an AppWidgetProvider and add an click listener on it (to change the color of the button, for example)? </p>

<p>In an Activity I would just use findViewById() and setOnClickListener(), but I can't do that in the AppWidgetProvider.</p>
