SearchView.OnQueryTextListener - java

I am trying to search for items with a SearchView but I do not know why I can not find the possible way, can you help me?

In line *adapter.setFilter(filteredModelList);
setFilter is in red.
My error is *Error:(182, 16) error: cannot find symbol method setFilter(List)

1. Instead of declaring Adapter as:
private RecyclerView.Adapter adapter;
Use:
private Campos_Adapter adapter;
2. In addition, initialize adapter from onCreateView() and use adapter.notifyDataSetChanged() from parseData() method.
Update onCreateView() and parseData() as below:
//Creating a List of jornadas
private List<Estadisticas> listJornadas;
//Creating Views
private RecyclerView recyclerView;
private RecyclerView.LayoutManager layoutManager;
private Campos_Adapter adapter;
private List<Estadisticas> mCountryModel;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
...........
...................
listJornadas = new ArrayList<Estadisticas>();
adapter = new Campos_Adapter(listJornadas, getActivity());
recyclerView.setAdapter(adapter);
recyclerView.addItemDecoration(new DecoracionLineaDivisoria(getActivity()));
getData();
.........
.............
return view;
}
//This method will parse json data
private void parseData(JSONArray array){
for(int i = 0; i<array.length(); i++) {
Estadisticas campo = new Estadisticas();
JSONObject json = null;
try {
json = array.getJSONObject(i);
campo.setNombre_campo(json.getString("nombre_campo"));
campo.setPoblacion(json.getString("poblacion"));
campo.setEquipo(json.getString("equipo"));
campo.setTelefono(json.getString("telefono"));
campo.setGeo(json.getString("geo"));
campo.setUrl(json.getString("url"));
campo.setEmail(json.getString("email"));
campo.setEscudo(json.getString("escudo"));
} catch (JSONException e) {
e.printStackTrace();
}
listJornadas.add(campo);
adapter.notifyDataSetChanged();
}
}
UPDATE:
java.lang.NullPointerException: Attempt to invoke interface method
'java.util.Iterator java.util.List.iterator()' on a null object
reference at
com.ramon.campos.Campos.FragGridCampos.filter(FragGridCampos‌​.java:185)
Your mCountryModel is null. You have not initialized it. In onQueryTextChange() try below code:
#Override
public boolean onQueryTextChange(String newText) {
mCountryModel.addAll(listJornadas);
final List<Estadisticas> filteredModelList = filter(mCountryModel, newText);
adapter.setFilter(filteredModelList);
return true;
}

FragGridCampos.java
public class FragGridCampos extends Fragment implements SearchView.OnQueryTextListener{

I want to fetch data from json file from the internet using url, After doing all the codes RecyclerView says no adapter attached. I am not able to find out what is wrong with my code.

There might be some problem in this code:

This is the Adapter class

#Override

}
public class ViewHolder extends RecyclerView.ViewHolder
{
public TextView txtviewBankName;
public TextView txtviewAddress;
public TextView txtviewIfsc;
public TextView txtviewBranch;
public TextView txtviewBankId;
public TextView txtviewCity;
public TextView txtviewDistrict;
public TextView txtviewState;
public ViewHolder(View itemView) {
super(itemView);
txtviewBankName = (TextView)itemView.findViewById(R.id.bankName);
txtviewAddress = (TextView)itemView.findViewById(R.id.address);
txtviewIfsc = (TextView)itemView.findViewById(R.id.ifsc);
txtviewBranch = (TextView)itemView.findViewById(R.id.branch);
txtviewBankId = (TextView)itemView.findViewById(R.id.bankId);

txtviewDistrict = (TextView)itemView.findViewById(R.id.district);

Your JSON string has some wrong characters, it should be like this
[{"ifsc":"ABHY0065001","bank_id":60,"branch":"RTGS-HO","address":"ABHYUDAYA BANK BLDG., B.NO.71, NEHRU NAGAR, KURLA (E), MUMBAI-400024","city":"MUMBAI","district":"GREATER MUMBAI","state":"MAHARASHTRA","bank_name":"ABHYUDAYA COOPERATIVE BANK LIMITED"}]
then for parsing this json you can use the com.google.Gson library like this
Type listType = new TypeToken<ArrayList<ListItem>>() {}.getType();
String s = "[{\"ifsc\":\"ABHY0065001\",\"bank_id\":60,\"branch\":\"RTGS-HO\",\"address\":\"ABHYUDAYA BANK BLDG., B.NO.71, NEHRU NAGAR, KURLA (E), MUMBAI-400024\",\"city\":\"MUMBAI\",\"district\":\"GREATER MUMBAI\",\"state\":\"MAHARASHTRA\",\"bank_name\":\"ABHYUDAYA COOPERATIVE BANK LIMITED\"}]";
List<ListItem> items = new Gson().fromJson(s, listType);
then you can set this list as input into your Adapter then assign your adapter to your recycler.

I have a tabLayout in which there is Log Fragment tab it store all the incoming calls details in LogsData List Object and set .
New callLogs is updated after App close and restart but I want to refresh my RecyclerView when the call is in ringing state.
My LogFragment
public class LogsFragment extends Fragment {
private RecyclerView mRecyclerView;

And my PhoneStateReceiver Class
public class PhoneStateReceiver extends BroadcastReceiver {

String incomingNumber;
String state;
DateFormat timeFormat;
Context context;
String date;
String cName;
ArrayList data;

incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
cName = getContactName(incomingNumber, context);
timeFormat = new SimpleDateFormat("EEE, d MMM yyyy, HH:mm");
date = timeFormat.format(Calendar.getInstance().getTime());
Log.d(TAG, date);
String phoneState = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (phoneState.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
data.add(new LogsData(cName, incomingNumber, date));
tinydb.putListObject("LogData", data);
Toast.makeText(context, date + " " + incomingNumber + " " + cName, Toast.LENGTH_SHORT).show();
}

}
public String getContactName(final String phoneNumber, Context context) {
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
String[] projection = new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME};
String contactName = "";
Cursor cursor = context.getContentResolver().query(uri, projection, null, null, null);
if (cursor != null) {
if (cursor.moveToFirst()) {
contactName = cursor.getString(0);
}
cursor.close();
}
return contactName;
}
}
I update my codes please see it.

Use EventBus to do it
In your LogsFragment prepare subscriber like this:
#Subscribe(threadMode = ThreadMode.MAIN)
public void onMyEvent(Object o) {
/* Refresh your adapter */
data = tinyDB.getListObject("LogData", LogsData.class);
mListadapter = new ListAdapter(data);
mListadapter.notifyDataSetChanged();
mRecyclerView.setAdapter(mListadapter);
};
And in your PhoneStateReceiver call your subscriber like this:
EventBus.getDefault().post(new Object());
Do not forget to register and unregister your subscriber in LogsFragment
You can read more about EventBus in here

I need to parse JSON data into HorizontalScrollView with Retrofit2. I parsed it into ListView succesfully, but I haven't imagination how to do it into HorizontalScrollView. Google can't give me right answer.
My code with ListView below.
P.S. I want to do HorizontalScrollView instead of ListView.
Like this.
MyForecastAdapter.java
public class MyForecastAdapter extends ArrayAdapter<Forecast> {
List<Forecast> forecastList;
Context context;
private LayoutInflater inflater;
public MyForecastAdapter(Context context, List<Forecast> objects) {
super(context, 0, objects);
this.context = context;
this.inflater = LayoutInflater.from(context);
forecastList = objects;
}
#Override
public Forecast getItem(int position) {
return forecastList.get(position);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder viewHolder;
if (convertView == null) {
View view = inflater.inflate(R.layout.activity_row, parent, false);
viewHolder = ViewHolder.create((RelativeLayout) view);
view.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
Forecast item = getItem(position);
viewHolder.textViewTemp.setText(item.getMain().getTemp());
viewHolder.textViewHumidity.setText(item.getMain().getHumidity());
return viewHolder.relativeLayout;
}
private static class ViewHolder {
public final RelativeLayout relativeLayout;
public final TextView textViewTemp;
public final TextView textViewHumidity;
private ViewHolder(RelativeLayout relativeLayout, TextView textViewTemp, TextView textViewHumidity) {
this.relativeLayout = relativeLayout;
this.textViewTemp = textViewTemp;
this.textViewHumidity = textViewHumidity;
}
public static ViewHolder create(RelativeLayout relativeLayout) {
TextView textViewTemp = (TextView) relativeLayout.findViewById(R.id.textViewTemp);
TextView textViewHumidity = (TextView) relativeLayout.findViewById(R.id.textViewHumidity);
return new ViewHolder(relativeLayout, textViewTemp, textViewHumidity);
}
}
}
ForecastList.java
public class ForecastList {
#SerializedName("list")
#Expose
private ArrayList<Forecast> forecasts = new ArrayList<>();
public ArrayList<Forecast> getForecasts() {
return forecasts;
}
public void setForecasts(ArrayList<Forecast> forecasts) {
this.forecasts = forecasts;
}
}
Forecast.java - getters/setters.

public interface ApiService {
#GET("/data/2.5/forecast?q=Kirov,ru&appid=/../")
Call<ForecastList> getMyJSON();
}
RetrofitClient.java
public class RetrofitClient {
private static final String ROOT_URL = "http://api.openweathermap.org";
private static Retrofit getRetrofitInstance() {

Call<ForecastList> call = apiService.getMyJSON();
call.enqueue(new Callback<ForecastList>() {
#Override
public void onResponse(Call<ForecastList> call, Response<ForecastList> response) {
if (response.isSuccessful()) {
forecastList = response.body().getForecasts();
adapter = new MyForecastAdapter(MainActivity.this, forecastList);
listView.setAdapter(adapter);
} else {
Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
}
}
#Override

}
});
}

You can use horizonatal Scroll View using Recycle View with LinearLayoutManager with constructor new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
Use this code .....
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
forecastList = new ArrayList<>();
parentView = findViewById(R.id.parentLayout);
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
myList = (RecyclerView) findViewById(R.id.listView);
myList.setLayoutManager(layoutManager);
ApiService apiService = RetrofitClient.getApiService();
Call<ForecastList> call = apiService.getMyJSON();
call.enqueue(new Callback<ForecastList>() {
#Override
public void onResponse(Call<ForecastList> call, Response<ForecastList> response) {
if (response.isSuccessful()) {
forecastList = response.body().getForecasts();
adapter = new MyForecastAdapter(MainActivity.this, forecastList);
myList.setAdapter(adapter);
} else {
Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
}
}
#Override
public void onFailure(Call<ForecastList> call, Throwable t) {
}
});
}
and change ListView into RecycleView in XML and in code also.....
