Question

I have a variable “ekinismi”. And when I add String(s) to it. I receive the “eklist” from another activities with EkinIsmi() method.

static List<String> eklist = new ArrayList<String>();

public List<String> EkinIsmi() 
    {
        return eklist;
    }

But this list return me “null” and my list items. But I just want to receive only list items. How can I do that with a for loop or something. Null(s) are not String so I can’t use equals or compareto for split the null(s) from my list.

This code sample is working good for me, but as you see, I give the list items number to the “i”. But it has to understand what the list has.

if(ekinismi.size() > 1)
            {
                for(int i=ekinismi.size()-1; i>ekinismi.size()-3; i--)
                dosyaAdi.setText(String.valueOf(ekinismi.get(i)));
            }

I click the position = 0 list item and then click the next one and at the dosyaAdi.setText() is set first and next one’s “s” . I mean I need to clear all the list items. Because it holds the first one’s. Where should I put the list.clear()? Actually, I already do that but it didn’t change anything, I think maybe I put it to wrong line.

List<String> list = new ArrayList<String>();
        if( ekvarmı == true)
        {
            if(ekinismi.size() >= 1)
            {
                for(String s : ekinismi) 
                    {
                       if(s != null) 
                       {
                           list.add(s);
                       }
                    }
                 dosyaAdi.setText(String.valueOf(list));
            }
        }

for(String s : ekilist) {
   if(s != null) {
       doSomething(s);
   }
