没有在Corona SDK中得到适当的滚动视图。

我在查看记分板时出现了问题。我正在给我的scrollview和其中的内容提供初始值。当我最初打开我的记分板时，内容显示在正确的位置，但当我向下滚动然后向上滚动时，它不会回到初始位置。 请检查所附的记分板视图的截图。有人可以告诉我在这种情况下应该怎么做吗？

提前致谢。

local function scrollListener( event )
    local phase = event.phase
    if phase == "began" then
        print( "Scroll view was touched" )
        for key,value in pairs(event) do
            print("pranav",key,value)
        end

    elseif phase == "moved" then
        --print( "Scroll view was moved" )
        print("over",event.x)

        if(event.x>414)then
            event.x=358
        end

    elseif phase == "ended" then
        print( "Scroll view was released" )
        print("ended",event.x)
    end

    -- In the event a scroll limit is reached...
    if event.limitReached then
        if event.direction == "up" then
            print "Reached top limit"
        elseif event.direction == "down" then
            print "Reached bottom limit"
