copy下面代码，运行试试

local width = window:width()
local height = window:height()

local color_Gray = Color(105, 105, 105, 1)
local contentView = View()
contentView:width(width):height(height)

showLabel:width(width - 16)
scrollView:addView(showLabel)

----以下代码不用管，显示UI用的
local btnInfo = { "showStatusBar", "hideStatusBar" }

local btnScrollView = ScrollView(true):height(50):width(width):padding(4, 0, 4, 0)
contentView:addView(btnScrollView)
local tabsContainer = LinearLayout(LinearType.HORIZONTAL):setWrapContent(true)
btnScrollView:addView(tabsContainer)

local tabs = {}
for i, v in ipairs(btnInfo) do
    local start, last = string.find(v, "demo.")
    local name
    if last and last < #v then
        name = string.sub(v, last + 1, #v)
    else
        name = v
    end
    local tab = Label():setWrapContent(true):textAlign(TextAlign.CENTER):setMinWidth(80):marginLeft(5):padding(0, 5, 5, 5):height(50):fontSize(14):text(name):bgColor(Color(211, 211, 211, 1)):textColor(Color(0, 0, 0, 1))
    tabsContainer:addView(tab)
    tabs[v] = tab
end

for i, v in pairs(tabs) do
    if i == btnInfo[1] then
        v:onClick(function()
            System:showStatusBar()
        end)
    elseif i == btnInfo[2] then
        v:onClick(function()
            System:hideStatusBar()
        end)
    end
end
