How to insert rows into TableView in Corona? - lua

Question

I'm trying to render the match results (string.find) in to a Row, with kinda works... but its only displaying the last match. so if I match 'jan' and 'kevin' it will; only list 'kevin'
Is there a way to fix this ?
code:
local MasterData = xml:loadFile( "sample.xml")
local XMLdataTEST = {}
for i=1,#MasterData.child do
XMLdataTEST[i] = MasterData.child[i]
end
inputNumber = 1
check1 = 'jan'
check2 = 'kevin'
for i=1,#XMLdataTEST do
local data1 = XMLdata[i].child[1].value
local data2 = XMLdata[i].child[2].value
local data3 = XMLdata[i].child[3].value
local data4 = XMLdata[i].child[4].value
input1 = string.lower( data1.. "" )
input2 = string.lower(_G['check' .. inputNumber] )
input = input2
if string.find( input1.. "" , input ) then
print(inputNumber.. " match with " ..input)
inputNumber = inputNumber + 1
local function onRowRender( event )
local row = event.row
local number = display.newText( row, "" .. row.index .. " - ", 12, 0, nil, 18 )
number:setReferencePoint( display.CenterLeftReferencePoint )
number.x = 15
number.y = row.height * 0.5
number:setFillColor( 0, 0, 0 )
local name = display.newText(row, input1, 12, 0, nil, 18 )
name:setReferencePoint( display.CenterLeftReferencePoint )
name.x = number.x + number.contentWidth
name.y = row.height * 0.5
name:setFillColor( 0, 0, 0 )
local score = display.newText(row,"testy", 12, 0, nil, 18 )
score:setReferencePoint( display.CenterLeftReferencePoint )
score.x = display.contentWidth - score.contentWidth - 20
score.y = row.height * 0.5
score:setFillColor( 0, 0, 0 )
end
local tableView = widget.newTableView
{
left = 0,
top = 0,
height = display.contentHeight,
width = display.contentWidth,
onRowRender = onRowRender,
onRowTouch = onRowTouch,
listener = scrollListener
}
tableView.x = display.contentWidth + display.contentWidth/2 + 50
transition.to( tableView, { time=500, x=display.contentWidth / 2, transition=easing.inOutExpo } )
for i = 1, 1 do
local isCategory = false
local rowHeight = 40
local rowColor = { 255, 255, 255 }
local lineColor = { 220, 220, 220 }
tableView:insertRow
{
isCategory = isCategory,
rowHeight = rowHeight,
rowColor = rowColor,
lineColor = lineColor,
onRender = onRowRender,
}
end
end
end

Your tableView being declared within the outer loop meant that the first instance of it would be transitioned over by the second instance. And a quick look over the docs indicates that each event.row allows an optional params table to include any data you may need to render the row.
local MasterData = xml:loadFile( "sample.xml")
local XMLdataTEST = {}
for i=1,#MasterData.child do
XMLdataTEST[i] = MasterData.child[i]
end
-- ** moved from loop **
local function onRowRender( event )
local row = event.row
local number = display.newText( row, "" .. row.index .. " - ", 12, 0, nil, 18 )
number:setReferencePoint( display.CenterLeftReferencePoint )
number.x = 15
number.y = row.height * 0.5
number:setFillColor( 0, 0, 0 )
-- ** changed to use params table **
local name = display.newText(row, row.params.input1, 12, 0, nil, 18 )
name:setReferencePoint( display.CenterLeftReferencePoint )
name.x = number.x + number.contentWidth
name.y = row.height * 0.5
name:setFillColor( 0, 0, 0 )
local score = display.newText(row,"testy", 12, 0, nil, 18 )
score:setReferencePoint( display.CenterLeftReferencePoint )
score.x = display.contentWidth - score.contentWidth - 20
score.y = row.height * 0.5
score:setFillColor( 0, 0, 0 )
end
