particular title(fetched from api) using searchview?
You can achieve suggestions related to your search query using recyclerview and adapters.
[1] Create new adapter and put your setMovieList() and getFilter() into it.
[2] Set that adapter into recyclerview of suggestions and notify adapter when you get your arraylist of suggestions.
check below code
public void onResponse(retrofit2.Call<List<StartLearning.SlModel>> call, Response<List<StartLearning.SlModel>> response) {
movieList = response.body();
if(movieList.size()!=0){
tvSuggestions.setVisibility(View.VISIBLE);
suggestionAdapter=new SuggestionAdapter(Search.this,movieList);
recyclerViewSuggestions.setAdapter(suggestionAdapter);
Log.e("TAG", "onResponse: size of movielist "+movieList);
suggestionAdapter.getFilter().filter(query);
suggestionAdapter.notifyDataSetChanged();
suggestionAdapter.setMovieList(Search.this,movieList);
}
else{
tvSuggestions.setVisibility(View.VISIBLE);
tvSuggestions.setText("No Suggestions Found");
}
/*generateDataList(movieList);
Log.d("TAG","Response = "+movieList);
slAdapter.setMovieList(getApplicationContext(),movieList);*/
}
how to display data of different api ids to different items of recycle view?
As far I understand what you want to do, according to that I assume that you need following changes:
In WhatsAndroidAdapter
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(context, NextActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("title", WAmdel.get(getAdapterPosition()).getTitle());
intent.putExtra("id", WAmdel.get(getAdapterPosition()).getId());
context.startActivity(intent);
}
});
In NextActivity
Intent intent = getIntent();
String title = intent.getStringExtra("title");
String id = intent.getStringExtra("id");
String hello=intent.getStringExtra("hii");
getSupportActionBar().setTitle(title);
/*Create handle for the RetrofitInstance interface*/
DescriptService service = DescriptClientInstance.getRetrofitInstance().create(DescriptService.class);
Call<DescriptionModel> call = service.getAllPhotos(id);
call.enqueue(new Callback<DescriptionModel>() {
@Override
public void onResponse(Call<DescriptionModel> call, Response<DescriptionModel> response) {
// progressDialog.dismiss();
DescriptList=response.body();
generateDataList(DescriptList);
}
@Override
public void onFailure(Call<DescriptionModel> call, Throwable t) {
// progressDialog.dismiss();
Toast.makeText(getApplicationContext(), "Something went wrong...Please try later!", Toast.LENGTH_SHORT).show();
}
});
In DescriptService
@GET("/v1/android_tutorials/single_tutorial")
Call<DescriptionModel> getAllPhotos(@Query("tutorial_id") String id);
SearchView query hint before clicking it
Use this XML:
android:queryHint="hint"
app:queryHint="hint"
app:defaultQueryHint="hint"
android:iconifiedByDefault="false" // this line
app:iconifiedByDefault="false"
app used for {android.support.v7.widget.SearchView}

Inside your Custom Adapter write a function like this.
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter .CustomRecyclerHolder> {
private Context context;
private ArrayList<String> arrayList = null, stringArrayList;
private OnItemClickListener listener;
public CustomAdapter(Context context, ArrayList<String> items) {
this.context = context;
this.arrayList = items;
this.stringArrayList = new ArrayList<String>();
this.stringArrayList.addAll(items);
}
@Override
public CustomAdapter.CustomRecyclerHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_item, parent, false);
return new CustomRecyclerHolder(itemView);
}
@Override
public void onBindViewHolder(CustomAdapter.CustomRecyclerHolder holder, int position) {
holder.item.setText(arrayList.get(position).toString());
}
public class CustomRecyclerHolder extends RecyclerView.ViewHolder{
protected TextView item;
public CustomRecyclerHolder(View v){
super(v);
item = (TextView) v.findViewById(R.id.itemNametxt);
v.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (listener != null) {
listener.onItemClick(item.getText().toString());
}
}
});
}
}
@Override
public int getItemCount() {
return this.arrayList.size();
}
public void filter(String filterString) {
filterString = filterString.toLowerCase(Locale.getDefault());
arrayList.clear();//Your list of items
if(filterString.length() == 0) {
arrayList.addAll(stringArrayList);
//stringArrayList - 2nd list of items
}
else {
for(String item : stringArrayList){
if(item.toLowerCase(Locale.getDefault()).contains(filterString)) {
arrayList.add(item );
}
}
}
notifyDataSetChanged();
}
public void setOnItemClickListener(OnItemClickListener listener){
this.listener = listener;
}
public interface OnItemClickListener{
public void onItemClick(String item);
}
}

Is there a way to modify fetched results with a predicate after they are initialized?
Is there a way to modify fetched results with a predicate after they
are initialized?
Well... no, not in the way you try to do this, and even if you'd try to create it with NSFetchRequest instance, which is reference, and allows to change predicate later, that wouldn't work, because SwiftUI's FetchRequest stores copy of provided fetch request (or creates own with provided parameters)... so, no. But...
You can break apart view providing fetch request parameters with view constructing fetch request and showing result.
Here is a demo of approach (important part of it) which gives you possibility to get results with different dynamically changed predicates:
struct MasterView: View {
@State var predicate: NSPredicate? = nil
var body: some View {
VStack {
Button(action: { // button just for demo
self.predicate = NSPredicate(format: "title contains[c] %@", "h")
}, label: { Text("Filter") })
ResultView(predicate: self.predicate)
}
}
}
struct ResultView: View {
@FetchRequest
var events: FetchedResults<Event>
@Environment(\.managedObjectContext)
var viewContext
init(predicate: NSPredicate?) {
let request: NSFetchRequest<Event> = Event.fetchRequest()
request.sortDescriptors = [NSSortDescriptor(keyPath: \Event.timestamp, ascending: true)]
if let predicate = predicate {
request.predicate = predicate
}
_events = FetchRequest<Event>(fetchRequest: request)
}
var body: some View {
List {
ForEach(events, id: \.self) { event in

Your result screen before search -> 
Your result screen after search -> 
data is not getting displayed in retrofit
Might be i got the problem.
Problem is here @GET("/v1/android_tutorials/single_advance?") you have? in the end of your url and you also have @Query("advance_id") field that mean your request contain two ?. you request currently look like this.
/v1/android_tutorials/single_advance??advance_id="xxxx"
Remember when you add @Query("advance_id") to your request this by default add ? to your your. So remove? from your url end. Your url should look like this
@GET("/v1/android_tutorials/single_advance")
