Описание тега android-custom-view
A tag for questions related to building and using custom graphical widgets on the Android platform.
An Android custom view is created by extending the base class of all Android widgets, the View class. If the custom view is designed to hold other views, then the ViewGroup class should be extended instead. A custom view that extends the View class has several methods that should be implemented in order to make the custom view work, methods like onMeasure() and onDraw().
