Android Programming

This is an Android application development textbook published by China Machine Press in 2016, compiled by Wei Yanjun. Part of a higher education planning textbook series, it is aimed at college students and self-learners who already have some programming foundation. The book is organized around an "example-driven, progressive" approach. It opens with an overview of Android's development, the SDK architecture, and basic development tools, and uses Eclipse to demonstrate the creation, running, and project structure of the simplest Android program. It then fills in Java fundamentals, including basic data types and variables, operators and expressions, control structures such as sequence, branching, looping, and exceptions, and composite data types such as arrays, strings, date and time, collections, maps, and math and random types. Chapter 3 moves into object orientation, covering packages and classes, member variables and methods, constructors, objects, inheritance, abstract classes, and interfaces. On this basis, the book turns to Android interface and interaction: it introduces common layouts such as LinearLayout, GridLayout, FrameLayout, RelativeLayout, AbsoluteLayout, and TableLayout; basic controls and event handling for Button, TextView, EditText, CheckBox, RadioButton, ProgressBar, SeekBar, Spinner, ListView, date and time pickers, and clock controls; and the various resource files under the res directory and project deployment methods. It then covers title bar customization, options menus and context menus, multiple Activities and Intent navigation, and dialogs such as Toast and AlertDialog, forming the basic framework for multi-screen programming. The latter half extends to practical technologies such as file operations, multimedia, network communication, databases, and sensors, and ties the preceding knowledge points together with a "weather forecast robot" client case. The appendixes gather the Android SDK, common Java packages and classes, an index of common Android resources, common Eclipse shortcuts, and methods for debugging Android programs. The book comes with electronic courseware and example source code, and each chapter includes comprehensive examples and exercises, making it suitable as a course textbook or supplementary reference.
