Today we worked with graphics and images and learned about drawable .When you need to display static images in your app, you can use the drawable class and its sub classes to draw shapes and images. A drawable is a general abstraction for something that can be drawn. The various subclasses help with specific image scenarios, and you can extend them to define your own drawable objects that behave in unique ways.
Today we started working on UI of our application and we developed sin up and login forms and customized it's design. The user interface for an Android app is built using a hierarchy of layouts ( ViewGroup objects) and widgets ( View objects). Layouts are containers that control how their child views are positioned on the screen. Widgets are UI components such as buttons and text boxes.
