Ecommerce App in CodenameOne

Question

Hi I am a newbie in CodenameOne am now creating a eCommerce app using CodenameOne resource editor ,I have used multilist for displaying products . I have checked the checkbox feature wherein I got the checkbox for all my items .My question here is by code in statemachine how do I get the name of product checked by the user and how to get whether the checkbox is checked or not .I tried implementing findMultiList().getSelected() but it returns always true if I check r uncheck.

Please help me also it would be great if you could tell me how to integrate google drive in my project because I need to pull data from excel sheet and populate it in the list.

You need to get the model and traverse the elements within it:

ListModel<Map<String, Object>> model = (ListModel<Map<String, Object>>)findMultiList(c).getModel();
ArrayList<Map<String, Object>> items = new ArrayList<>();
for(int iter = 0 ; iter < model.getSize() ; iter++) {
   Map<String, Object> current = model.getItemAt(iter);
   String checked = (String)current.get("emblem");
   if(checked != null && "true".equals(checked)) {
       items.add(current);
   }
}

I haven't tried this code but it should work. Notice that the name "emblem" is the default name used for the MultiButton/MultiList but you can change it to be anything.

You can place a break point on the for loop and inspect the map elements as you traverse them to see how this works.
