- 32. Custom Components Extend anexisting View class or subclass with your own class. Override some of the methods from the superclass. The superclass methods to override start with 'on', for example, onDraw(), onMeasure(), and onKeyDown(). This is similar to the on... events in Activity or ListActivity that you override for lifecycle and other functionality hooks. Use your new extension class. Once completed, your new extension class can be used in place of the view upon which it was based. example: extend ImageView and add some rounded border http://developer.android.com/guide/topics/ui/custom- components.html
