Answer 1

Make the elementry ArrayList global to the class and change the logic like this,

 list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View viewClicked,
                        int position, long id) {
                String data = parent.getAdapter().getItem(position);
                final int index = elementy.indexOf(data);
                if(index == 0){
                    Intent i = new Intent(MainActivity.this,Utwor0.class);
                    startActivity(i);
                 }

    }};

Answer 2

Its still not working. I read something about viewHolder but its still the same problem. I write VH below, maybe i'm doing something wrong, i dont know.

class ViewHolder{
    TextView text=null;
}



public View getView(int position, View convertView, ViewGroup parent){

ViewHolder holder;


if (convertView==null){
    LayoutInflater inflater = getLayoutInflater(); 
    convertView =inflater.inflate(R.layout.single_row, null);
    holder=new ViewHolder();
    holder.text=(TextView)convertView.findViewById(R.id.textView1);
    convertView.setTag(holder);
}
else{
    holder=(ViewHolder)convertView.getTag();
}

holder.text.setText(elementy.get(position));
return (convertView);   
}
