Check the logs. The error message should be printed there.

How are you reading the logs? From the IDE? It should show you the error line.

Can you upload the project (File - Export as zip) and the steps required to reproduce it?

 

[arnold steger]

i have sendet my project per mail (Monday, September 21, 2015 10:58 PM)
show the error line in Search View Module

 

[Erel]

I didn't receive it. If it is a large project then it is better to try to reproduce it in a smaller project.

 

[arnold steger]

1.click of button Suchen read all my files.
2.click write all files in a list
first line of listview open searchfield.
In this line stopped app and show line 53 in SearchView-Module (lv.Clear)

java.lang.RuntimeException: Object should first be initialized (ListView).

 

[Erel]

You have modified SearchView code. It is important to write this when you post a question as the error can be related to the changes you did.

This code is wrong:

For Each it As Item In li
     If full.Length > MAX_LIMIT And it.SearchText.Contains(full) = False Then
       Continue
     End If
     lv.AddTwoLines2(it.Title, it.Text, it)
   Next

The list holds strings not Items.

 

[arnold steger]

i have find my problem.
how can modification the code for return Position from list
svN_ItemClick(Value As String, Position As Int)

 

[arnold steger]

I have resolved in a other way.
This code work fine.

Sub searchNamen_Click

If MarkerGeladen=False Then
    NamenList.Initialize
    NamenData.Initialize
    Namen.AddSingleLine("Name suchen...")
    NamenData.Add("Name suchen...")

    Dim PointsTempG() As String = Regex.Split(",",Namen_ListeGross.Get(i))
    NamenData.Add(PointsTempG(0)&","&PointsTempG(1)&","&PointsTempG(2))
    Namen.AddTwoLines(PointsTempG(2),PointsTempG(0)&","&PointsTempG(1))
    NamenList.Add(PointsTempG(2))
    Next
    For i = 1 To Namen_ListeKlein.Size-1
    Dim PointsTempK() As String = Regex.Split(",",Namen_ListeKlein.Get(i))
    NamenData.Add(PointsTempG(0)&","&PointsTempG(1)&","&PointsTempG(2))
