} }
After actions described above it is enough to transform provided by Canvas native key-codes to our internal. This can be made by simple calling the method adoptKeyCode(), like following:
protected void keyPressed(int keyCode) { int internalKeyCode = KeyCodeAdapter.getInstance().adoptKeyCode(keyCode); switch (keyCode) { case KeyCodeAdapter.SOFT_KEY_LEFT: // some processing break; case KeyCodeAdapter.BACK_KEY: // some processing break; default: } ... }
