Android Question problem when use same time costum list view & location

Tayfur · Jun 9, 2015

My code has Erel's costum listview.
(https://www.b4x.com/android/forum/t...xible-list-based-on-scrollview.19567/#content)

and I added Location manager v.1.1. I learningn geo coordinates from cell.

normaly only clistview in my code >>> work.
normaly only location manager in my code>>> work.

Same time working costumlistwev and Locationa manager.>> NOT work
it is broken when it works "Sub etiket_Click"

sorry... i cant understant.

*****************************
module :: "control_view" is your costum listview. (https://www.b4x.com/android/forum/th...xible-list-based-on-scrollview.19567/#content) Not change it
+
"Location manager" library.

*************************************************************

Now I changed code,

first step; "Locatioan manager" library very 15sec run "Sub Location_LocationChanged ..."
I changed code. And I add locationmanager.stoprequest when LM read firt time . After LM stopped run "Sub Location_LocationChanged ..."

second step;
I add the code to a lot of places in "Sub etiket_Click" (label_clik)

now I cant recive error.

But; why I revice error?? i think problem is (getparent) ????
But your are expert.

Our code is here http://s000.tinyupload.com/?file_id=33002176722434561778

for catch broken code , you can alot of time push on list when code running;

You should use ContactUtils to get the contacts list and you most probably need to only take the "visible" contacts. The current method you use is too slow.

This is the error line:

B4X:

 bt=st&ANS.get(lbl.Tag)

You need to check the code and find out why you are trying to get index #2 when there are only 2 items in this list.

You need to check the code and find out why you are trying to get index #2 when there are only 2 items in this list.

I will use your code.

I woeked this problem code last night. and I found somethings. I cheked step by step. I find a interesting thing when it broke code.
"Getitemfromview (it is your costum scrollview)" sub has a working time is null or chekbox or animations...,

on broke time, it has a GPS location. and after ruining code is broke.

İ think problem is Location maneger. Because LM is working 1 time every 15sec. Your wiew and Lm crash. this is my idea?
how am i fix it?

This is most probably the the problem: "This code will not work if you call this sub as Sender will not be set" (correctly).

I added project; how can i fix it

You can only use the Sender keyword when the sub is executed as a result of an event. If you call the sub in your code then you shouldn't use sender.

Erel please please some code; because I am not expert.
i use first time "r.RunMethod" and reflaction. therefore I cant understandt your way /words.

please some code...

my projects is stop.

It has nothing to do with r.RunMethod.

The problem is here:
index = clv3.GetItemFromView(Sender)

You expect Sender to hold the view that raised the event. This will not be the case when the checkbox is checked. You can create a new method that accepts a single View parameter and pass Sender to this sub.

CODE OR SAMPLE ??? I hate reflection.
Your description is adequate for someone who knows better of the B4A program / reflection /Java.
So, I only look
