How to change background color in Android application?

Design and write a GUI application that can create a keyboard onscreen?

• In Java, design and write a GUI application that can help users learn “touch type” (i.e. type correctly without looking at the keyboard). The application should display a virtual keyboard and should allow the user to watch what he or she is typing on the screen without looking at the actual keyboard. Use JButtons to represent the keys. As the user presses each key, the application highlights the corresponding JButton on the GUI and adds the character to the JTextArea that shows what the user has typed so far. To highlight a JButton, use its setBackground method to change its background color. When the key is released, reset its original background color. You can obtain the JButton’s original background color with the getBackground method before you change its color. You can test every key, type “The quick brown fox jumped over a lazy dog.” You can find other pangrams on the web

• Answer:

  Easy.. Type "the quick brown fox jumped over a lazy dog..." Good luck!
