[victormedranop]

Hi I need to accelerate fills data on a list view.
because its to slow downloading and have to wait to complete de download to start working with it.
listview it's slow.

I should try ultimate listview


I have this

job1.Download("http://ibsj.org/app/index.php")
Sub JobDone (Job As HttpJob)
  Log("JobName = " & Job.JobName & ", Success = " & Job.Success)
  If Job.Success = True Then
  Select Job.JobName
  Case "Job1"
   Log("JOB 1")
   Dim parser As JSONParser
 parser.Initialize(Job.GetString)
 Dim root As List = parser.NextArray
 For Each colroot As Map In root  
 'Dim date As String = colroot.Get("date")
 Dim thumb_url As String = colroot.Get("thumb_url")
 Dim video_url As String = colroot.Get("video_url")  
 Dim author As String = colroot.Get("author")   
 Dim audio_url As String = colroot.Get("audio_url")
 Dim title As String = colroot.Get("title")   
 display_data(title,author,trim_string2(RemoveAccents(thumb_url)),audio_url,video_url)
 ListView1.Invalidate  
 Next
  End Select
  Else
  Log("Error: " & Job.ErrorMessage)
  ToastMessageShow("Error: " & Job.ErrorMessage, True)
  Return
  End If
  Job.Release
  job_complete = 1
  WebView1.Visible = False
End Sub

Sub display_data (data1 As String, data2 As String, data3 As String ,data4 As String, data5 As String )
 If data3.Length = 0 Then
 ListView1.AddTwoLinesAndBitmap( trim_string(data1) , data2,LoadBitmapSample(File.DirAssets,"play2.png",15dip,15dip)) 
 Else
 ListView1.AddTwoLinesAndBitmap( trim_string(data1) , data2,LoadBitmapSample(File.DirAssets,data3,15dip,15dip)) 
 ListView1.Invalidate  
 End If
 'DoEvents
 Sleep(1000)
 List1.Add(data1)
 List2.Add(data2)
 List3.Add(data3)
 List4.Add(data4)
 List5.Add(data5)
End Sub

ListView is very fast.

Downloading resources from the internet can be slow. See this example that uses CustomListView to add the items and later add the images when they are ready: https://www.b4x.com/android/forum/t...ple-way-to-download-images.30875/#post-179512
