Android app for Android capture without view edittext

Question

How can I capture hardware keyboard events without using the EditText field?

For example, in a simple action, display a square on the screen when “B” is pressed on the slide keyboard. I want to turn it blue when "G" presses, turns it to green, etc.

I don't need help with the color code, just how to intercept a keystroke

This is not about a soft or virtual keyboard.

Answer 1

Android classes typically provide event handlers that you can implement when you subclass them. The class Activityhas the following event handlers:

• onKeyDown(int keyCode, KeyEvent event)
• onKeyLongPress(int keyCode, KeyEvent event)
• onKeyMultiple(int keyCode, int repeatCount, KeyEvent event)
• onKeyShortcut(int keyCode, KeyEvent event)
• onKeyUp(int keyCode, KeyEvent event)

, :

• onKeyDown(int, KeyEvent)
• onKeyUp(int, KeyEvent)
