my java class

            Primero = new Adapter(Consultageneral.this, js_primero);

            final ListAdapter adapter = new SimpleAdapter(Consultageneral.this, articulos,
                    R.layout.item_catego, new String[]{"codigo", "descrip", "fabricante", "modelo", "Linea", "precio"},
                    new int[]{R.id.txtCodigo, R.id.txtdescart , R.id.txtFabri , R.id.txtrubro , R.id.txtGrupo , R.id.txtP});
                     lista.setAdapter(adapter);
                         registerForContextMenu(lista);

that's what he found after scrole the list
