Hello, i am tottaly new at the corona, i have problem with ScrollView.

For my application i want add scrollview like on facebook, i scroll down, and this stay.

this is my code:

[lua]local background = display.newImageRect( “background.png”, 360, 570 )

background.x = display.contentCenterX

background.y = display.contentCenterY

local label1 = display.newImage( “label.png”, 160, 0 )

local label2 = display.newImage( “label.png”, 160, 100 )

local label3 = display.newImage( “label.png”, 160, 200 )

local label4 = display.newImage( “label.png”, 160, 300 )

local label5 = display.newImage( “label.png”, 160, 400 )

local label6 = display.newImage( “label.png”, 160, 500 )

local label7 = display.newImage( “label.png”, 160, 500 )

local b = display.newText( “b”, 40, 110, native.systemFont, 30)

b.x = display.contentWidth * 0.5

b.y = display.contentHeight - (display.contentHeight*0.03)

b:setFillColor( 255, 0, 0 )

local labelmenu = display.newImage( “labelmenu.png”, 160, 500 )

local a = display.newText( “a”, 40, 110, native.systemFont, 30)

a.x = display.contentWidth * 0.5

a.y = display.contentHeight - (display.contentHeight*0.75)

a:setFillColor( 255, 0, 0 )

[/lua]

Default language? 

First you need to requiere the widget library. Second you need to insert the objects inside the scrollview widget. Third scroll. That’s it.

#3

What language?

Thanks for help, but i have other problem.

Does not want to see blank white space when i move up and down i want limit.

this is my code, how can you  tell if there is anything to improve:

[lua]-----------------------------------------------------------------------------------------

–

– main.lua

–

local widget = require( “widget” )

local background = display.newImageRect( “background.png”, 640, 780 )

background.x = display.contentCenterX

background.y = display.contentCenterY

local labelmenu = display.newImage( “labelmenu.png”, 160, 500 )

– ScrollView listener

local function scrollListener( event )

 

    local phase = event.phase

    if ( phase == “began” ) then print( “Scroll view was touched” )

    elseif ( phase == “moved” ) then print( “Scroll view was moved” )

    elseif ( phase == “ended” ) then print( “Scroll view was released” )

    end

 

    – In the event a scroll limit is reached…

    if ( event.limitReached ) then

        if ( event.direction == “up” ) then print( “Reached bottom limit” )

        elseif ( event.direction == “down” ) then print( “Reached top limit” )

        elseif ( event.direction == “left” ) then print( “Reached right limit” )

        elseif ( event.direction == “right” ) then print( “Reached left limit” )

        end

    end

 

    return true

end

local scrollView = widget.newScrollView {

    horizontalScrollDisabled = true,

    width = 360,

    height = 780,

    left = 0,

    top = -45,

    --scrollWidth = 0,

    --scrollHeight =  0

}

 

local view = scrollView:getView()

 

– Create a image and insert it into the scroll view

local label1 = display.newImage( “label.png”, 160, 50 )

local label2 = display.newImage( “label.png”, 160, 150 )

local label3 = display.newImage( “label.png”, 160, 250 )

local label4 = display.newImage( “label.png”, 160, 350 )

local label5 = display.newImage( “label.png”, 160, 450 )

local label6 = display.newImage( “label.png”, 160, 550 )

local label7 = display.newImage( “label.png”, 160, 650 )

local label8 = display.newImage( “label.png”, 160, 750 )

local labelmenu = display.newImage( “labelmenu.png”, 160, 500 )

scrollView:setScrollHeight( 1050 ) 

–scrollView:insert( background )

scrollView:insert( label1 )

scrollView:insert( label2 )

scrollView:insert( label3 )

scrollView:insert( label4 )

scrollView:insert( label5 )

scrollView:insert( label6 )

scrollView:insert( label7 )

scrollView:insert( label8 )

[/lua]

Default language = Spanish, French, etc?

I really do not understand what you want to say. When you said white space do you refer to the background?

#5

default language is Polish

I do not want to scrolling to this white background, just a limit.

#6

Maybe the ScrollToPosition api is the one you are looking for.

I have already repaired. Thanks for help.
