Hello mam,

Samsung Gear S2 SDK(2.3.2)

I used native circle progress bar. I have one UI . Genlist. Item 1- Scan, Item2 Vibration. Once user press item1 then progress bar will visible. Prgressbar naviframe called.  

Problem1: i want to stop progress bar once BLE scaning is completed. 

Problem2: When progress bar is running with black screen. i want to show progressbar + Scanned Beacon UI where beacons will be listed.

Problem3 ( Genlist issue) : I want to refresh genlist, i intialize genlist  (title, genlist naviframe, etc) before scanning operation is start. once beacon found then i append items to genlist. Here i am facing issue with unique values. If i passed simple text to pointer then get unique values but if i passed pointer value list will be display all values, uniqueness is not there.

Problem1:

   
This Create_list_view() called from parent: (item1: BLE Scannig,  Item 2: Vibration)

Hi,

For the Problem1 you may try with this line below:
 

evas_object_hide(progressbar);

You may simply hide the progress bar instead of trying to stop once the scanning is done.

For the Problem3, to update the genlist you may use the elm_genlist_item_item_class_update() function. Please follow this link. You'll find a code snippet here containing instructions about updating genlist.

Unfortunately I couldn't understand the second problem. I think, it'll be better if you share some pictures to show the requirements. 

Moreover, you may also go through the UIComponents sample app to get some basic ideas about different types of ui components.
