While searching using EditText, the items in Recyclerview is duplicating, if i am searching fast

In my project, there is need of searching data from server using keyword. After search, i am displaying results using RecyclerView . While searching fast, the data in RecyclerView is duplicating. If searching slowly, it's working fine. Any suggestions are appreciated. Thank you.
The below code for making server call:
private void callSearchUserApi(final String searchText, int currentPage, boolean clearData) {
isApiCallInProcess = true;
String URL = "userinfo/api/v1/user-search/" + "?page=" + currentPage;
if (!Connectivity.isConnected(activity)) {
Common.snackBarNoConnection(activity, activity.getString(R.string.no_conection));
//setOnProgressbarVisibility(View.GONE);
return;
}
if (clearData) {
globalSearchUsersModelList.clear();
//BS globalSearchUserResultsAdapter.notifyDataSetChanged();
}
ApiInterface apiCall = ApiClient.getApiService(activity);
final Call<SearchUsersModel> globalUserSearchApiCall = apiCall.searchUser(
URL,
searchText);
globalUserSearchApiCall.enqueue(new Callback<SearchUsersModel>() {
#Override
public void onResponse(Call<SearchUsersModel> call, Response<SearchUsersModel> response) {
if (response.isSuccessful() && response.body().getStatus().equalsIgnoreCase(Common.SUCCESS_RESPONSE)) {
//BS globalSearchUsersModelList.addAll(response.body().getData().getData());
for (int i = 0; i < response.body().getData().getData().size(); i++) {
SearchUsersModel.DataBeanX.DataBean dataBean = new SearchUsersModel.DataBeanX.DataBean();
dataBean.setDesignation(response.body().getData().getData().get(i).getDesignation());
dataBean.setFull_name(response.body().getData().getData().get(i).getFull_name());
dataBean.setGender(response.body().getData().getData().get(i).getGender());
dataBean.setId(response.body().getData().getData().get(i).getId());
dataBean.setPlace(response.body().getData().getData().get(i).getPlace());
dataBean.setProfile_pic(response.body().getData().getData().get(i).getProfile_pic());
globalSearchUsersModelList.add(dataBean);
/*BS if (!globalSearchUsersModelList.contains(response.body().getData().getData().get(i)))
globalSearchUsersModelList.add(response.body().getData().getData().get(i));*/
}
CURRENT_PAGE = response.body().getData().getPage();
isLoading = false;
if (response.body().getData().isNext() == false)
isLastPage = true;
else
isLastPage = false;
if (globalSearchUsersModelList.size() == 0) {
rv_GlobalsearchList.setVisibility(View.GONE);
rl_placeholderGSPeople.setVisibility(View.VISIBLE);
tv_placeholderGSPeople.setText(activity.getString(R.string.no_search_found) + " " + searchText);
} else {
rv_GlobalsearchList.setVisibility(View.VISIBLE);
rl_placeholderGSPeople.setVisibility(View.GONE);
}
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override
public void run() {
globalSearchUserResultsAdapter.notifyDataSetChanged();
}
});
}
if (searchTextsList.size() > 0) {
String sText = searchTextsList.get(0);
searchTextsList.remove(0);
callSearchUserApi(sText, FIRST_PAGE, true);
} else
isApiCallInProcess = false;
}
#Override
public void onFailure(Call<SearchUsersModel> call, Throwable t) {
isApiCallInProcess = false;
}
});
}
This is my Adapter.
public class GlobalSearchUserResultsAdapter extends RecyclerView.Adapter<GlobalSearchUserResultsAdapter.SearchViewHolder> {
private Context context;
private List<SearchUsersModel.DataBeanX.DataBean> searchUserList;
public GlobalSearchUserResultsAdapter(Context context, List<SearchUsersModel.DataBeanX.DataBean> searchUserList){

return new GlobalSearchUserResultsAdapter.SearchViewHolder(view);
}
#Override
public void onBindViewHolder(GlobalSearchUserResultsAdapter.SearchViewHolder holder, int position) {
if ( searchUserList.get(position).getGender().equals("M")) {
holder.iv_userImage.setBackgroundResource(R.drawable.white_border_with_circle_appblue);
Common.setGlideImage((GlobalSearchActivity)context,
holder.iv_userImage,
/*searchUsersModel*/searchUserList.get(position).getProfile_pic(),
R.drawable.male,
true);
} else if (searchUserList.get(position).getGender().equals("F")) {
holder.iv_userImage.setBackgroundResource(R.drawable.white_border_with_circle_pink);
Common.setGlideImage((GlobalSearchActivity)context,
holder.iv_userImage,
searchUserList.get(position).getProfile_pic(),
R.drawable.female,
true);
} else {
Common.setGlideImage((GlobalSearchActivity)context,

}
holder.tv_userName.setText(searchUserList.get(position).getFull_name());
holder.tv_userName.setTypeface(Common

holder.tv_place.setText(searchUserList.get(position).getPlace());
holder.tv_place.setTypeface(Common
.getFontTypeface(context, GlobalConstants.FONT_AVENIR_MEDIUM));
holder.designation.setText(searchUserList.get(position).getDesignation());
}
#Override
public int getItemCount() {
return searchUserList.size();
}
public class SearchViewHolder extends RecyclerView.ViewHolder{
private ImageView iv_userImage;
private TextView tv_userName;
private TextView tv_place;
private TextView designation;
public SearchViewHolder(View itemView) {
super(itemView);
this.iv_userImage = (ImageView) itemView.findViewById(R.id.imageSearch);
this.tv_userName = (TextView) itemView.findViewById(R.id.nameSearch);
tv_userName.setTypeface(Common.getFontTypeface(context,
GlobalConstants.FONT_AVENIR_MEDIUM));
this.designation = (TextView) itemView.findViewById(R.id.designation);
designation.setTypeface(Common.getFontTypeface(context,
GlobalConstants.FONT_AVENIR_MEDIUM));
this.tv_place = (TextView) itemView.findViewById(R.id.placeSearch);
tv_place.setTypeface(Common.getFontTypeface(context,
GlobalConstants.FONT_AVENIR_LIGHT));
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
context.startActivity(new Intent(context, ProfileActivity.class)//ThirdParty
.putExtra(GlobalConstants.KEY_THIRD_PARTY_ID, searchUserList.get(getAdapterPosition()).getId()));
}
});
}
}
}

You just had to clear the globalSearchUsersModelList list just before for loop, because API call is asynchronous.
globalSearchUsersModelList.clear();// Important one
for (int i = 0; i < response.body().getData().getData().size(); i++) {
// do your stuff
}

I think the issue come from your getItemId implementation. The way you implement it, the recycler view will identify an item according to its position in the list.
If you change this and use unique identification for instance searchUserList.get(position).id (if your User object has an unique ID) the problem should be fixed
You can also add in your activity adapter.setHasStableIds(true)

I want to add an Incidencia Object from this fragment

incidencia.setHoraSolucion(mTimeDisplay.getText().toString());
Toast toast = Toast.makeText(getContext(), "Registrado", Toast.LENGTH_SHORT);
toast.show();
}
});
return x;
}
And I want to see the list in this fragment
public class ListaIncidenciasTroncalFragment extends Fragment {
Context context;
GestureDetector detector;
private RecyclerView rvListaIncidencias;
private ListaIncidenciasTroncalAdapter mlistaIncidenciasTroncalAdapter;
public ListaIncidenciasTroncalFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View x = inflater.inflate(R.layout.listaincidenciastroncalfragment,null);
context = x.getContext();
detector = new GestureDetector(getActivity(), new RecyclerViewOnGestureListener());
rvListaIncidencias=(RecyclerView)x.findViewById(R.id.rv_listaIncidenciasTroncal);
rvListaIncidencias.setLayoutManager(new LinearLayoutManager(getContext()));
mlistaIncidenciasTroncalAdapter = new ListaIncidenciasTroncalAdapter();
rvListaIncidencias.setAdapter(mlistaIncidenciasTroncalAdapter);
//I ADD THIS ONE FOR TEST AND ITS SUCCESFULL BUT I DONT KNOW HOW TO ADD IT BY THE BUTTON IN ANOTHER FRAGMENT
Incidencia incidencia = new Incidencia();
incidencia.setFechaRegistro("06/06/2017");
incidencia.setHoraRegistro("10:30");
incidencia.setTipoFalla("Atasco Moneda");
incidencia.setNomEstacion("Javier Prado");
incidencia.setFechaSolucion("07/06/2017");
incidencia.setHoraSolucion("9:20");
mlistaIncidenciasTroncalAdapter.add(incidencia);
return x;
}

In your first fragment, define an interface which would pass your Incidencia object to the host activity. The interface method is called in your button's onClick():
public class YourFirstFragment extends Fragment {
private OnButtonClickedListener mListener;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
...
botonAgregaIncidencia.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
...
mListener.onButtonClicked(incidencia);
}
});
}
public interface OnButtonClickedListener {
void onButtonClicked(Incidencia incidencia);
}
}
Then, in your activity, implement this interface. The overridden method will also bundle the object and pass to your next fragment as the fragment argument:
public class YourActivity implements YourFirstFragment.OnButtonClicked {
.
.
.
#Override
public void onButtonClicked(Incidencia incidencia){
ListaIncidenciasTroncalFragment fragment = new ListaIncidenciasTroncalFragment();
Bundle args = new Bundle();
args.putParcelable("yourKey", incindencia);
fragement.setArguments(args);
getSupportFragmentManager().beginTransaction().replace(R.id.yourFragmentContainer, fragment).commit();
}
}
Finally, in your second fragment, extract the bundle or arguments like so and use it however you want:
Bundle args = getArguments();
Incidencia incidencia = args.getParcelable("yourKey");

Retrofit passing specific json nested objects to next activity

I have a JSON nested object and i have been trying to pass for example, stations "name" to next activity in the onClick method. 2 questions:
1) Have i set my model class right or is there a better way?
2) What steps am i missing to pass "name" from stations from the specific object clicked onto the next activity?
My error for code provided (

Change your code to following:
public StationsAdapter(List<Bus> stations) {
List<Bus.stations> busStations = new ArrayList<>();
for (Bus bus : stations) {
busStations.addAll(bus.getStationInfo());
}
}
Issue is that you don't assign nothing to your mBusStations variable, that's why NPE throws.
Btw, don't use that confusing naming. Im talking about stationInfo in your Bus class.

One ListView Receiving Data from Multiple Class

I am looking for something like this:
several <ItemTemplate> in one ListView.
But it was in .ASP and above my level.
What I need
Class Vitals: vTime, BP, Heart Rate, Respirations per Minute, etc.
Class Medications: mTime, RxName, RxRoute, RxDose, RxDoseUnit, etc.
Class Procedures: pTime, Intubation, IV insertion, Defibrillation, etc.
Classes Vitals, Medications and Procedures to be based on user input that inject in to a ListView (sorted chronologically). A "Many-to-One" if I may.
I've went through hours of "CustomAdapter & ListView" tutorials, code samples, walkthroughs.
Here is my current code (trashed and scattered) to show that I am actively working towards a solution:

I'd appreciate any and everything;
I'm working on a NEMSIS . org project;
I may even be searching with the wrong search terms for what I need.
All help is appreciated

have you try the getViewTypeCount() method in adapter,
it can define different itemView for your different data types.
for your case you need to define three layout items .
search some demos,it may help you .

I want to pass hashmap from custom arrayadapter to activity?

I want to pass HashMap or ArrayList Object from Custom ArrayAdapter to activity which fills the ListView.I want to send checked records recordId field.I m new To Android.Any Suggestion Plz

Pass the adapter a reference to the activity. Then provide a method in the activity that the adapter can call.
In adapter:
private MyActivity activity;
public void setActivity(MyActivity activity) {
this.activity = activity;
}
In Activity:
// create adapter
adapter.setActvity(this);
In adapter (when you want to pass parameters back to activity):
activity.setHashMap(mymap);

My CustomAdapter Class::
class SearchResultAdapter extends ArrayAdapter{
Context context;
int layoutResourceId;
private ArrayList<SearchResultModel> results;
public SearchResultAdapter(Context context, int layoutResourceId, ArrayList<SearchResultModel> results) {
super(context, layoutResourceId, results);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.results = results;
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
View row = convertView;
SearchResultHolder holder=null;
if(row == null)
{
LayoutInflater vi = ((Activity)context).getLayoutInflater();
row = vi.inflate(R.layout.listitemrow, null);
holder = new SearchResultHolder();
holder.jobdetails = (TextView)row.findViewById(R.id.jobdetails);
row.setTag(holder);
}
else
{
holder = (SearchResultHolder)row.getTag();
}
SearchResultModel model = results.get(position);
if (model != null)
{
row.setId(Integer.parseInt(model.getjob_id()));
String result=
"<font color=#5D2E8C>"+model.getjob_title()+"</font><br>" +
"<font color=#737373>"+model.getpost_date()+"</font><br>"+model.getuser_name()+"<br>" +
"<font color=#3C5A98>"+model.getsalary()+" Rs (Per Annum)</font><br>"+
"<font color=#97AB40>"+model.getjob_location()+"," +
" "+model.getjob_exp_min()+"-"+model.getjob_exp_max()+" year";
holder.jobdetails.setText(Html.fromHtml(result));
}
return row;
}
class SearchResultHolder
{
TextView jobdetails;
}
}
My ListView in the Main Method That would use the Above ArrayAdapter.
SearchResultAdapter adapter;
ListView lv;
adapter=new SearchResultAdapter(this, R.layout.listitemrow, model);
//Here model is the ArrayList<SearchResultModel>
lv=getListView();
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener()
