Fala galera, estou com um problema ao criar um ListView em um ListFragment. Fiz um teste com um ListActivity e funciona perfeitamente, mas no ListFragment não vai. Preciso fazer em Fragment pois tenho um menu lateral na aplicação.
ListActivity funcionando:
public class BakeryListActivity extends ListActivity implements AdapterView.OnItemClickListener {
public static final String APP_NAME = "PanApp";
public static final String URL = "https://panapp-backend.appspot.com/_ah/api";
private TextView tv = null;
private ArrayList<Map<String,String>> list = null;
private SimpleAdapter adapter = null;
private String[] from = { "name", "street" };
private int[] to = { android.R.id.text1, android.R.id.text2 };
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tv = new TextView(this);
tv.setText("Lista de Padarias");
tv.setGravity(Gravity.CENTER);
getListView().addHeaderView(tv);
new BakeryListAsyncTask(this).execute();
getListView().setOnItemClickListener(this);
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(this, "Item: " + position, Toast.LENGTH_SHORT).show();
}
private class BakeryListAsyncTask extends AsyncTask<Void, Void, CollectionResponseBakery> {
Context context;
private ProgressDialog pd;
public BakeryListAsyncTask(Context context) {
this.context = context;
}
protected void onPreExecute(){
super.onPreExecute();
pd = new ProgressDialog(context);
pd.setMessage("Listando Padarias...");
pd.show();
}
protected CollectionResponseBakery doInBackground(Void... unused) {
CollectionResponseBakery quotes = null;
try {
BakeryApi.Builder builder = new BakeryApi.Builder(AndroidHttp.newCompatibleTransport(),
new AndroidJsonFactory(), null).setRootUrl(URL);
builder.setApplicationName(APP_NAME);
BakeryApi service = builder.build();
quotes = service.list().execute();
} catch (Exception e) {
Log.d("Erro", e.getMessage(), e);
}
return quotes;
}
protected void onPostExecute(CollectionResponseBakery quotes) {
pd.dismiss();
ArrayList<Map<String, String>> list = new ArrayList<Map<String, String>>();
List<Bakery> _list = quotes.getItems();
for (Bakery quote : _list) {
HashMap<String, String> item = new HashMap<String, String>();
item.put("name", quote.getFantasyName());
item.put("street", quote.getStreet());
list.add(item);
}
adapter = new SimpleAdapter(BakeryListActivity.this, list,android.R.layout.simple_list_item_2, from, to);
setListAdapter(adapter);
}
}
}
ListFragment que não funciona:
public class BakeryFragment extends ListFragment implements OnItemClickListener {
public static final String APP_NAME = "PanApp";
public static final String URL = "https://panapp-backend.appspot.com/_ah/api";
private SimpleAdapter adapter = null;
private String[] from = { "name", "street" };
private int[] to = { android.R.id.text1, android.R.id.text2 };
public BakeryFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_bakery_list, container, false);
return rootView;
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
new BakeryListAsyncTask(getActivity().getApplicationContext()).execute();
getListView().setOnItemClickListener(this);
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getActivity(), "Item: " + position, Toast.LENGTH_SHORT).show();
}
private class BakeryListAsyncTask extends AsyncTask<Void, Void, CollectionResponseBakery> {
Context context;
private ProgressDialog pd;
public BakeryListAsyncTask(Context context) {
this.context = context;
}
protected void onPreExecute(){
super.onPreExecute();
pd = new ProgressDialog(context);
pd.setMessage("Listando Padarias...");
pd.show();
}
protected CollectionResponseBakery doInBackground(Void... unused) {
CollectionResponseBakery bakeries = null;
try {
BakeryApi.Builder builder = new BakeryApi.Builder(AndroidHttp.newCompatibleTransport(),
new AndroidJsonFactory(), null).setRootUrl(URL);
builder.setApplicationName(APP_NAME);
BakeryApi service = builder.build();
bakeries = service.list().execute();
} catch (Exception e) {
Log.d("Erro", e.getMessage(), e);
}
return bakeries;
}
protected void onPostExecute(CollectionResponseBakery bakeries) {
pd.dismiss();
ArrayList<Map<String, String>> list = new ArrayList<Map<String, String>>();
List<Bakery> _list = bakeries.getItems();
for (Bakery bakery : _list) {
HashMap<String, String> item = new HashMap<String, String>();
item.put("name", bakery.getFantasyName());
item.put("street", bakery.getStreet());
list.add(item);
}
adapter = new SimpleAdapter(getActivity().getApplicationContext(), list,android.R.layout.simple_list_item_2, from, to);
setListAdapter(adapter);
}
}
}
