Title: jListView.GetCheckedItemPosition always returns -1
Post by: Thyphoon on July 10, 2020, 12:11:11 am

Today I updated lawn and when I compiled a project of mine I noticed that jListView.GetCheckedItemPosition is always returning -1, maybe I has something to do with a recent update?

Can you do some diff in  "jListView.java"   for  "GetCheckedItemPosition"?

[LAMW folder "...\android_wizard\smartdesigner\java" ]

Like this?

Code: Pascal  [Select][+][-]

1.  
2. -      
3. -       // Fix GetCheckedItemPosition [by TR3E]
4. +                      
5.         public int GetCheckedItemPosition() {
6.                
7.                 for( int i = 0; i < alist.size(); i++ )
8. -                        if( alist.get(i).checked )
9. -                                return i;
10. -                      
11. +                if( alist.get(i).checked )
12. +                        return i;
13. +              
14.                 return -1;
15.         }      
16.  
17.  

It doesnt seems to have changed...

But whenever I use GetCheckedItemPosition it returns -1  wherever there is a item selected or not.

Maybe   @TR3E  can help here....

[Please,  if possible]  Can you do a simple project/example   and put it in some open drive?

Thanks!

I changed GetCheckedItemPosition  for GetItemIndex, I was misusing GetCheckedItemPosition to get the Index of the selected item and Adiv fixed it, sorry.
