Methods Summary
public static native int	getGameAction(int keyCode) Returns the game action associated with the given key code on the device. keyCode must refer to a key that is mapped as a game key on the device. The game action of the key is returned. The return value will be 0 if the key is not mapped to a game action, or it will be -1 if the keycode is invalid. param keyCode the key code return the corresponding game action (UP, DOWN, LEFT, RIGHT, FIRE, etc.)
public static native int	getKeyCode(int gameAction) Return the key code that corresponds to the specified game action on the device. gameAction must be a defined game action (Canvas.UP, Canvas.DOWN, Canvas.FIRE, etc.) Post-conditions: The key code of the key that corresponds to the specified action is returned. The return value will be 0 if the game action is invalid or not supported by the device. param gameAction The game action to obtain the key code for. return the key code.
public static native java.lang.String	getKeyName(int keyCode) Gets an informative key string for a key. The string returned should resemble the text physically printed on the key. For example, on a device with function keys F1 through F4, calling this method on the keycode for the F1 key will return the string "F1". A typical use for this string will be to compose help text such as "Press F1 to proceed." There is no direct mapping from game actions to key names. To get the string name for a game action, the application must call getKeyName(getKeyCode(GAME_A)) param keyCode the key code being requested return a string name for the key, or null if no name is available
public static native int	getSystemKey(int keyCode) Returns 0 if keyCode is not a system key. Otherwise, returns one of the EventConstants.SYSTEM_KEY_ constants. param keyCode get the system equivalent key. return translated system key or zero if it is not a system key.
