CustomListview with EditText

[andr3net0]

Hello,
i'm trying to edit the text on a edittext that is part of a item in a ListView.

When i write something and scroll down the text dissapears.
What is the solution based in the bellow code?

The main activity when button is clicked
-------------------------------------

String[] dados=artigos_selecionados.split(";#");
final ListView lv=(ListView)findViewById(R.id.listView);
ArrayList<OrcamentosHeaderClass> artigoslist=new ArrayList<OrcamentosHeaderClass>();
OrcamentosHeaderAdapter adapter= new OrcamentosHeaderAdapter(this,R.layout.layout_artigos_orcamentos);
lv.setAdapter(adapter);
lv.setEnabled(true);

for (int i=0 ; i<dados.length;i++){
System.out.println(dados);
String[] artigos=dados.split(";");
//ref,descricao,valor,quant
if (artigos[0]!=null){
String empresajuncao=artigos[0] +" - " + artigos[1];
String artigotratado=artigos[5].replace("Stock:","").replace("und","").replace(" ","");

OrcamentosHeaderClass obj=new OrcamentosHeaderClass(empresajuncao, artigos[2],artigos[3],artigotratado,artigos[4],artigos[6]);

adapter.add(obj);
adapter .notifyDataSetChanged();

}





}

---------------------------------
The Adapter
-------------------------------------------------------
public class OrcamentosHeaderAdapter extends android.widget.ArrayAdapter {


public List<DadosHolder> myItems;
private Integer count;

public OrcamentosHeaderAdapter(Context ctx, int resource){
super(ctx,resource);




}

@override
public View getView(int position, final View convertView, ViewGroup parent) {
View row=convertView;
final DadosHolder holder;


if(convertView==null){
LayoutInflater inflater=(LayoutInflater)this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row=inflater.inflate(R.layout.layout_artigos_orcamentos ,parent,false);
holder=new DadosHolder();

holder.ref=(TextView)row.findViewById(R.id.tv_ref_artigo);
holder.descricao=(TextView)row.findViewById(R.id.tv_descricao_artigo);
holder.valor=(TextView)row.findViewById(R.id.tv_precounit);
holder.quant=(EditText)row.findViewById(R.id.tb_quant);
holder.relacionado=(TextView)row.findViewById(R.id.tv_assoc);
holder.empresa=(TextView)row.findViewById(R.id.tv_empresa_artigo);
holder.precofinal=(TextView)row.findViewById(R.id.tv_precofinal);
row.setTag(holder);


}else {
holder=(DadosHolder) row.getTag();
}

OrcamentosHeaderClass orcamentosHeaderClass = (OrcamentosHeaderClass) getItem(position);

count=position;
System.out.println("POS" + count);
holder.ref.setText(orcamentosHeaderClass.getRef());
holder.descricao.setText(orcamentosHeaderClass.getDescricao());
holder.valor.setText(orcamentosHeaderClass.getValor() +"€");
holder.quant.setText(orcamentosHeaderClass.getQuant());
holder.relacionado.setText(orcamentosHeaderClass.getRelacionado());
holder.empresa.setText(orcamentosHeaderClass.getEmpresa());
holder.quant.addTextChangedListener(new TextWatcher() {
@override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {

}

@override
public void onTextChanged(CharSequence s, int start, int before, int count) {


System.out.println("Text "+ holder.quant.getText().toString());


}

@override
public void afterTextChanged(Editable s) {

}
});
holder.quant.setOnFocusChangeListener(new View.OnFocusChangeListener() {

@override
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus){
final int position = v.getId();
final EditText Caption=(EditText)convertView.findViewById(position);
System.out.println("Text "+ Caption.getText().toString());

//myItems.get(position).setQuant( Caption.getText().toString());
holder.quant.setText(Caption.getText().toString());

}
}


});

return row;

}
class DadosHolder{
TextView ref;
TextView descricao;
TextView valor;
EditText quant;
TextView relacionado;
TextView empresa;
TextView precofinal;





}
@override
public int getCount() {
//count= getCount();
return super.getCount();
//return myItems.size();


}

@override
public long getItemId(int position) {
return super.getItemId(position);
}




}
