Hello. Does anyone know how we could define the situation of jlistview
as read-only?
I wish sometimes the selected one could not be changed a selected
item.
Thanks.

Hi,

If you mean by read-only that a different item cannot be selected (I
believe the grid text is already read-only?) - Have you tried handling
the OnClickItem event to force a particular item to be selected?

This works for me..

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.ListView1ClickItem(  Sender     : TObject; itemIndex
 : integer; itemCaption: string) ;const k_always_selected = 1 ; //
items 0..2 , always keep item 1 selectedbegin  ListView1.SetSelection(
k_always_selected );end;

Thank you for your answer. It helped a lot.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.ListView1ClickItem(  Sender     : TObject; itemIndex
 : integer; itemCaption: string) ;const k_always_selected = 1 ; //
items 0..2 , always keep item 1 selectedbegin      // I define two
variables that take values from other parts of the code.     //
 Fastat determines whether the selected item can be changed and     //
 curindex is the value of the item       if fastat =-1 then     
Begin         jListView1.SetItemChecked(itemIndex,False);       
 jListView1.SetItemChecked(curindex ,False);      end;          end;
