I have some dummy problem, I need to get Spinner Item Position from the Fragment to this class:
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.FragmentManager;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.Spinner;

import com.example.nortti.politrange.objects.Site;
import com.example.nortti.politrange.utils.WebApiAdapter;
import com.example.nortti.politrange.views.GeneralFragment;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Iterator;
public class PersonCatalog implements ICatalog{
private final String COMMAND_PREFIX = "/api/stats/1";
private final WebApiAdapter apiAdapter = new WebApiAdapter(COMMAND_PREFIX);
private ArrayList<Person> catalogList = new ArrayList<Person>();
private Site site;
public PersonCatalog(Site site) {
this.site = site;
}
#Override
public ArrayList<Person> getCatalogList() {
return catalogList;
}
public void populateData() {
JSONArray jsonObject = null;
try {
jsonObject = (JSONArray)(new JSONParser()).parse(apiAdapter.select(null));
} catch (IOException e) {
e.printStackTrace();
} catch (ParseException e) {
e.printStackTrace();
}
catalogList.clear();
Iterator<JSONObject> iterator = jsonObject.iterator();
while(iterator.hasNext()) {
JSONObject o = iterator.next();
catalogList.add(new Person((String)o.get("personName"),(int)(long)o.get("rank")));
}
}
}
I broke my head, I don't know how to do it. Please help! Should I use some Intents or create some getters?

Any idea how to fix this? I tried to use inflate however it failed to work as shown it is missing the home items xml enter image description here.
Before you say i have cleared and rebuild and all the FAQ ways to fix this
You're updating wrong list instance
Create one method inside adapter
public updateList(List<HomeModel> list) {
this.list = list;
notifyDataSetChanged()
}
And call it like :
reference.addSnapshotListener(new EventListener<QuerySnapshot>() {
#Override
public void onEvent(#Nullable QuerySnapshot value, #Nullable FirebaseFirestoreException error) {
...
adapter.updateList(new HomeModel(
model.getUserName(),
model.getProfileImage(),
model.getImageUrl(),
model.getUid(),
model.getComments(),
model.getDescription(),
model.getId(),
model.getTimestamp(),
model.getLikeCount()
));
}
}
});
I am having a GridList View in which I am passing data from firebase. When I click on the items it works fine without filtering but when I filter it with searchView then it does not update the index of the list and then provides a different item's context.
I do not know how to update the item while filtering.

Either implement a Filterable interface in the adapter or update your onQueryTextChange implementation.
Whenever you are typing, every time you are creating a new adapter with filtered data.
try this.. create new method in adapter
public void updateData(List<CategoryModelClass> catList){
this.catList = catList;
notifyDataSetChanged();
}
and call from onQueryTextChange
#Override
public boolean onQueryTextChange(String newText) {
//adapter.getFilter().filter(newText);
resultData = new ArrayList<>();
for (CategoryModelClass categoryModelClass : catList) {
if (categoryModelClass.getName().toLowerCase().contains(newText.toLowerCase())) {
resultData.add(categoryModelClass);
}
adapter.updateData(resultData);
}
return true;
}

I hope, you can help me. Thank you very much & sorry for my bad english.
First you have to set your TextView and EditText invisible in your XML, by adding android:visibility="invisible" to the XML of your TextView and EditText.
Then you have to use setVisibility(View.VISIBLE) after you have set the checkbox, like this:
yourcheckbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (b) {
//if checkbox is checked (b == true)
yourTextView.setVisibility(View.VISIBLE);
yourEditText.setVisibility(View.VISIBLE);
}
if (!b) {
//if checkbox is not checked (b == false)
yourTextView.setVisibility(View.INVISIBLE);
yourEditText.setVisibility(View.INVISIBLE);
}
}
});
If you first want to click a button and then check weather checkbox is checked, add this to your OnClickListenter:
if (yourcheckbox.isChecked) {
yourTextView.setVisibility(View.VISIBLE);
yourEditText.setVisibility(View.VISIBLE);
}

Now if I'm correct. My data from my API (link can be found in the code), will be added in an ArrayList called "names", but when I run my code my Recyclerview is empty. How do I add my JSON data to the RecyclerView and display it.
(For the record if I try it with String [] {"Example"} it will show a card with "Example")
Thanks in advance
How can I get String from my database and combine it with Image from my drawable folder. Help Please.
