示例

local function onUsername( event )
    if ( "began" == event.phase ) then
        -- This is the "keyboard appearing" event.
        -- In some cases you may want to adjust the interface while the keyboard is open.

    elseif ( "submitted" == event.phase ) then
        -- Automatically tab to password field if user clicks "Return" on virtual keyboard.
        native.setKeyboardFocus( passwordField )
    end
end
 
local function onPassword( event )
    -- Hide keyboard when the user clicks "Return" in this field
    if ( "submitted" == event.phase ) then
