帮我写个andlua多按钮布局

以下是一个基本的andlua多按钮布局代码示例，它包括5个按钮：

local widget = require("widget")

-- 创建背景
local background = display.newRect(display.contentCenterX, display.contentCenterY, display.contentWidth, display.contentHeight)
background:setFillColor(1, 1, 1)

-- 创建按钮
local button1 = widget.newButton({
    label = "Button 1",
    x = display.contentCenterX,
    y = display.contentHeight * 0.2,
    width = 200,
    height = 60,
    shape = "roundedRect",
    cornerRadius = 10,
    fillColor = { default={1,0,0,1}, over={1,0.5,0.5,1} },
    onPress = function(event)
        print("Button 1 pressed")
    end
})

local button2 = widget.newButton({
    label = "Button 2",
    x = display.contentCenterX,
    y = display.contentHeight * 0.35,
    width = 200,
    height = 60,
    shape = "roundedRect",
    cornerRadius = 10,
    fillColor = { default={0,1,0,1}, over={0.5,1,0.5,1} },
    onPress = function(event)
        print("Button 2 pressed")
    end
})

local button3 = widget.newButton({
    label = "Button 3",
    x = display.contentCenterX,
    y = display.contentHeight * 0.5,
    width = 200,
    height = 60,
    shape = "roundedRect",
    cornerRadius = 10,
    fillColor = { default={0,0,1,1}, over={0.5,0.5,1,1} },
    onPress = function(event)
        print("Button 3 pressed")
    end
})

local button4 = widget.newButton({
    label = "Button 4",
    x = display.contentCenterX,
    y = display.contentHeight * 0.65,
    width = 200,
    height = 60,
    shape = "roundedRect",
    cornerRadius = 10,
    fillColor = { default={1,1,0,1}, over={1,1,0.5,1} },
    onPress = function(event)
        print("Button 4 pressed")
    end
})

local button5 = widget.newButton({
    label = "Button 5",
    x = display.contentCenterX,
    y = display.contentHeight * 0.8,
    width = 200,
    height = 60,
    shape = "roundedRect",
    cornerRadius = 10,
    fillColor = { default={1,0,1,1}, over={1,0.5,1,1} },
    onPress = function(event)
        print("Button 5 pressed")
    end
})

这个例子使用了widget库来创建按钮，每个按钮都有一个唯一的标签和颜色。可以根据需要更改按钮的位置，颜色和其他属性
