Help in mobile phone keys commands needed

[thebestdesign]

Hi,
i'm creating a sudoku puzzle, I used a tiledlayer called 'board' which represent the puzzle.
I applied the keyPressed method below to read the numbers entered by the user and place them
to the appropriate place in the board. the program works fine in the Sun WTK emulator, But when i install the application in my mobile phone i found that when i press:
- '2': number 2 prints in the correct position then the cursor moves one position to the top.
- '4': number 4 printed in the correct position then the cursor moved one position to the left.
- '6': number 6 printed and cursor moved one position to the right.
- '8': number 8 printed and cursor moved one position down.
- anyother number: the program behaves correctly.

protected void keyPressed(int keyCode)
{

try{
String keyText = getKeyName(keyCode);
int keyNumber = Integer.parseInt(keyText);
int value = board.getCell(positionX, positionY);
if(value<= 10)
{
board.setCell(positionX, positionY, keyNumber);

}
}
catch(Exception e){}

}
Basically i don't have any problem to move around the board, i'm using the mobile phone's joystick to move from one cell to another, so i want to disable the functionality of movements used by the numbers '2,4,6,8' and use them only for input like the other buttons '1,3,7,9'.
is there anyway how to do it? because i found other sudoku mobile games on the internet they use the same concept, the mobile phone joystick is used to move between cells, and the numbers '1,2,...9' are used for board input only.

Please do you know any solution for this problem?

Thank you.

The problem is clear that the bug is obvious. If you use 2,4,6,8 for navigation and also for number input, then this problem is obvious. There are 2 ways in which sudoku games work.

1) Joystick is used for navigation and numbers keys are for input.
2) Joystick and 2,4,6,8 are both used for navigtion to support old phones without joystick also. In this case you have to press select button or any softkeys to enter an input. Once you press select the number keys are converted into input mode.

Hi codetiger,
thank you for the reply, basically that's what i'm looking for, option number 1:
1) Joystick is used for navigation and numbers keys are for input.
how to do it? i don't want the keys '2,4,6,8' to be used for any movements, i want them for input ONLY.
I hope to hear from you soon.

Instead of trying out the keyvalue conversion and stuff, just check the keycode like here

these are the values keypressed and keyreleased functions will bring when you check their value.

KEY_UP : -1
KEY_DOWN : -2
KEY_LEFT : -3
KEY_RIGHT : -4
KEY_SELECT : -5
KEY_CLEAR : -8
KEY_SEND : -10
KEY_END : 11

Hi,
i still didn't understand what do you mean, can you please explain it in more details? i'm still a beginner, not a professional.
Thanks.

Code: Select all

protected void keyPressed(int keyCode)
{
  if(keyCode == -1) {
      // upkey pressed
  } else if(keyCode == -2) {
      // downkey pressed
  } else if(keyCode == -3) {
      // leftkey pressed
  } else if(keyCode == -4) {
      // rightkey pressed
  }
}
