Creating Android Apps in Java
NEW

Join Mark Meretzky to learn how to create Android apps using the Eclipse IDE on Mac, PC, or Linux. The apps Mark demonstrates are composed of objects written in Java, plus a screen layout in XML. Find out how the Java code manipulates the XML to present a user interface including buttons, sliders, and other widgets. Draw text and graphics, respond to a touch or keystroke, and recognize a swipe or pinch. Three important design patterns involve views, which are visible areas on the screen. (1) A listener is an object whose methods are called in response to a stimulus. A view is made touch sensitive by plugging a listener into it. (2) A cursor is a source of data. A cursor is connected to an adapter, which encases each data item in a separate view object. (3) An adapter view displays the series of views created by the adapter. As our finale, we let a component of one app launch and communicate with a component of another app on the same device.

Prerequisite: Delegates should have a reading knowledge of Java.
