I have made a listfield by extending a Vertical manager where i am adding number of Horizontal manager.The HFM contains an image and a Text.Now the thing is that i want to get the index of the row when i click it.The problem is that for the first row it gives me 0 which is correcnt,but for the 2nd row it gives me 2 instead of 1,same for 3rd it gives 4 instead of 2.Please help

Just to avoid confusion, what you seem to have created is not a ListField, which is a completely different UI component than a series of HFMs added to a VFM.

You seem to be using getFieldIndex() on the VFM.  If all you had added were the HFM, then I would expect the indexes to go up by one. The fact that they go up by 2 indicates that you have added something else, like a NullField.  So I would check your code to confirm which Manager you are getting the Field index from and what else you add to that Manager.

No i havent use added any other field in Vfm except my hfm.And i am doing this from touchevent

getLeafFieldWithFocus().getManager().getIndex()

And which Manager is this getting the index for? 

In my experience, the Indexes don't lie.  The fact that it appears to be wrong would suggest a logic error in this approach. 

The debugger is your Friend here.  But split the statement up so you can check all components, say

Field focusField = getLeafWithFocus();

Manager focusManager = focusField.getManager();

Manager focusManagerManager = focusManager.getManager();

int focusIndex = focusManager.getIndex();

System.out.println("Focused on: " + focusField.toString() + " in " + focusManager.toString() + ", which is in: " + focusManagerManager.toString() + " at index: " + focusIndex);

Yes i have found the problem actualy i am also adding a seperator field to the vfm after adding each hfm

this.getLeafFieldWithFocus().getManager().getIndex())/2
