Problem in my search engine code

Question

As I can not use searchview I decided to use an edittext and a logica q found on a forum, but I go through difficulties have some idea?

Mainactivity.class

public void CarregarEncontrados()
{

   int textlength = et.getText().length();

   //Limpa o array com os estados encontrados
   //para poder efetuar nova busca
   lstEstados_Encontrados.clear();

   for (int i = 0; i < item.size(); i++)
   {
       if (textlength <= item.get(i).getResId())
       {
           //Verifica se existe algum item no array original
           //caso encontre é adicionado no array de encontrados
           if(et.getText().toString().equalsIgnoreCase((String)item[i].subSequence(0, textlength)))
           {
               lstEstados_Encontrados.add(item.get(i));
           }
       }
   }
}

Answer 1

Try to replace with this code:

Example

public void CarregarEncontrados()
{

   int textlength = et.getText().length();

   //Limpa o array com os estados encontrados
   //para poder efetuar nova busca
   lstEstados_Encontrados.clear();

   for (int i = 0; i < item.size(); i++)
   {
       if (textlength <= item.get(i).getResId())
       {
           //Verifica se existe algum item no array original
           //caso encontre é adicionado no array de encontrados
           if(et.getText().toString().equalsIgnoreCase(item.get(i).subSequence(0, textlength)))
           {
               lstEstados_Encontrados.add(item.get(i));
           }
       }
   }
}

What I understand from your question is that you are in trouble on line 129 of the picture.

If this is really the case, I believe the problem is that you try to access an element of ArrayList with [], but the correct is with the get(int index), that is, similar to what you do on line 125.
