Overview

Sets keyboard focus on a native.newTextField() or native.newTextBox() and shows (or hides) the keyboard. Pass nil to remove focus and hide the keyboard. Hiding the keyboard dispatches an "ended" phase to the native object's listener function.

Syntax

native.setKeyboardFocus( textField )
textField (required)

Object. ID/reference of the text field/box on which to set the keyboard focus, or nil to hide the keyboard.

Example

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
        native.setKeyboardFocus( nil )
    end
end
