i'm developing a game where i want to move a car based on the DPAD
navigation buttons. i'm using the onKeyDown() to capture the events
for left, right, up and down. the problem is that on the actual G1,
where the DPAD is replaced by a trackball, the left and right actions
are not detected. only the up and down events are registered. some of
the books mention that android automatically maps the trackball events
to DPAD events if the onTrackBallEvent() is not overridden. this
doesnt seem to be happening in my code. following is the code of the
onKeyDown() method:
public boolean onKeyDown(int key, KeyEvent kc){
switch (key){
case KeyEvent.KEYCODE_DPAD_LEFT:
isLeft = true;
currentCar = 1;
break;
case KeyEvent.KEYCODE_DPAD_RIGHT:
isRight = true;
currentCar = 2;
break;
case KeyEvent.KEYCODE_DPAD_UP:
SPEED = Math.min(30, SPEED + 10);
break;
case KeyEvent.KEYCODE_DPAD_DOWN:
SPEED = Math.max(10, SPEED - 10);
break;
default:
return super.onKeyDown(key, kc);
}
return true;
}
the whole thing runs fine on the emulator if i use the DPAD
keys ... but on an actual device (and the trackball option in the
emulator) the left and right options dont work. since the up and down
options work in all cases, i dont think its a problem with view having
focus.
any help would be greatly appreciated.
~thanks
