I'm developing an Android App with Android Studio, and I have the next problem: this is my Screen without search anything.
The first time I search something works fine, but when I search again it duplicates my values.
Second Search - duplicate results
Here is my code when I call to my Host and using my adapter:
cliente.post(URL, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
if (statusCode == 200) {
try {
JSONArray jsonArray = new JSONArray(new String(responseBody));
for (int i = 0; i < jsonArray.length(); i ) {
nombreRepuestoList.add(jsonArray.getJSONObject(i).getString("DESCRIPCION"));
referenciaRepuestoList.add(jsonArray.getJSONObject(i).getString("REFERENCIA_REPUESTO"));
}
ArrayAdapter adaptermaquina = new ArrayAdapter(getContext(), android.R.layout.simple_list_item_2, android.R.id.text1, nombreMaquinaList) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
TextView text1 = (TextView) view.findViewById(android.R.id.text1);
TextView text2 = (TextView) view.findViewById(android.R.id.text2);
text1.setText(nombreMaquinaList.get(position));
text2.setText(referenciaMaquinaList.get(position));
return view;
}
};
adaptermaquina.notifyDataSetChanged();
listaResultado.setAdapter(adaptermaquina);
} catch (JSONException e) {
e.printStackTrace();
}
I need some help please.
I tried using an empty adapter but it doesn't work and using listaResultado.clear()
neither works.
CodePudding user response:
Don't need to clear adatapter simply clear list values
nombreRepuestoList.clear();
referenciaRepuestoList.clear();
in yout code
if (statusCode == 200) {
nombreRepuestoList.clear();//1st
referenciaRepuestoList.clear();//2nd
try {
JSONArray jsonArray = new JSONArray(new String(responseBody));
for (int i = 0; i < jsonArray.length(); i ) {
nombreRepuestoList.add(jsonArray.getJSONObject(i).getString("DESCRIPCION"));
referenciaRepuestoList.add(jsonArray.getJSONObject(i).getString("REFERENCIA_REPUESTO"));
}
I hope it works for you
