我正在使用widget.newButton生成一个6x6的按钮网格。我希望用户能够通过触碰屏幕并拖动手指到所需的按钮来添加数字。例如，如果我想选择“811030”（即网格的顶行），那么我只需用手指在其上拖动即可。

这里是我目前的代码：

local widget = require( "widget" )

local function handleButtonEvent( event )
local phase = event.phase

if "moved" == phase then
    print("Button Pressed")
end
end

function tileRow(numTiles, padding)

local tileWidth = (display.contentWidth / numTiles) - padding
local x = padding/2
local y = display.contentHeight - numTiles * (tileWidth + padding)

    for i = 1, numTiles, 1 do
        for j = 1, numTiles, 1 do
            local myButton = widget.newButton
            {
                left = x,
                top = y,
                width = tileWidth,
                height = tileWidth,
                id = "button_"..i..j,
                label = math.random(0,9),
                onEvent = handleButtonEvent,
            }
            x = x + tileWidth + padding
        end
        x = padding/2
        y = y + tileWidth + padding
    end
end

tileRow(6,1)
