Loading dynamic layout in Android

Question

I'm currently making an application that uses a dynamic layout. It's my first time doing this and I'm doing it solely for the purpose of learning it. I managed to get it to load most of the data and show it correctly, but I'm having issues with the first item. For some reason it skips it and start with the 2nd item. It loads it into a variable but for some reason it isn't shown. I believe it has something to do with layout parameters but I can not find a reason for it behaving that way.

This is how it looks (take note, it should start with 141- ... item. It is loaded into a variable tho but not shown)

This is the code I'm using to load the items according to the variables

for (int i = 0; i <= id_l; i++)
            {
                RelativeLayout container = (RelativeLayout)findViewById(R.id.popisLinija);
                View item_layout = getLayoutInflater().inflate(R.layout.item_layout, null);
                Integer l = id_l;
                Log.d("id length: ", l.toString());
                Log.d("ID: ", id[i].toString());
                Log.d("Linija br: ", broj_linije[i]);
                Integer i2 = i;
                Log.d("i= ", i2.toString());

                item_layout.setId(i);
                item_layout.setTag("View");

                final Integer h = item_layout.getId();

                // fill in any details dynamically here
                assert item_layout != null;
                TextView textView = (TextView) item_layout.findViewById(R.id.item_text);

                if(broj_linije[i].equals("000"))
                {
                    textView.setText(naziv_linije[i]);
                }
                else
                {
                    textView.setText(broj_linije[i] + " - " + naziv_linije[i]);
                }


                textView.setTag("Text");


                RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
                if(i == 0)
                {
                    if (rlp != null) {
                        rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP, container.getId());
                    }
                }
                if(i > 0)
                {
                    if (rlp != null) {
                        rlp.addRule(RelativeLayout.BELOW, i-1);
                    }
                }


                FrameLayout item_button = (FrameLayout) item_layout.findViewById(R.id.item_button);
                item_button.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View arg0)
                    {
                        Integer a =  h;
                        Toast.makeText(getApplicationContext(), "Clicked me", Toast.LENGTH_SHORT).show();
                        Log.d("clicked", h.toString());
                    }
                });

                item_layout.setLayoutParams(rlp);
                container.addView(item_layout);
            }

I have checked if the item is loaded

Could anyone help me out on what am I doing wrong here? I would greatly appreciate it, I lost hours on this one trying all sorts of stuff with no result.

EDIT:

I have added my layout XML file

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="wrap_content"
