This is the recycleradapter i am using to populate array and checkbox.i want to setText for selected items.If i deselect the items i want to remove text from textview.When i select one item select and deselect is working properly.If i had more than one or if i select and deselct multiples times its not working giving index error
You are trying to delete an item at the given ReciclerView selection, but this position is wrong because you are doing:
selectedServiceArray.add(service);
So you don't know the position which is added because could be other items in this array. You have to request delete the object instead the position. Try this:
if(checkbox.isChecked){
String service=serviceArray.get(getAdapterPosition);
selectedServiceArray.add(service);
holder.serviceNameTv.setText(selectedServiceArray.toString);
} else {
String service=serviceArray.get(getAdapterPosition);
selectedServiceArray.remove(service);
holder.serviceNameTv.setText(selectedServiceArray.toString);
}
Do it like this : -
if(checkbox.isChecked){
String service=serviceArray.get(getAdapterPosition)
selectedServiceArray.add(service);
holder.serviceNameTv.setText(selectedServiceArray.toString);
}
else{
selectedServiceArray.remove(getAdapterPosition);
if (selectedServiceArray.size = 0) {
holder.serviceNameTv.setText("0");
} else{
holder.serviceNameTv.setText(selectedServiceArray.toString);
}

The code is working but it is taking 14-16 seconds to retrieve data of just 1 video from postgresql server. I think there might be a proper way of retrieving the data. Please help me with this.
Thank you.

Are you storing the video in your DB as a BLOB / CLOB.
What if you store the video in a different location, and save the address of the location in your DB. This way Db has to return a string, and UI / consumer can take care of rendering from the path.
I am learning java and android studio and I am trying to make a menu with each food item being an individual class with a set of allergens either having a true or false value. I add the objects of each class into an ArrayList to display them using a list view. I have implemented a search bar that works correctly, however I am trying to modify the onTextChanged function so if for example the user types in "gluten" it will return all food items that DO NOT contain that allergen.
My code is as follows below, with the commented out sections being some testing I have attempted

boolean gluten = false;
boolean shellfish = true;
}

}

public class ExchangesFrag extends Fragment {
RecyclerView recyclerView;
ExchangesAdapter adapter;
List<ExchangesSetterGetter> listItems;
SharedPrefManager sharedPreferences;
int uid;
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View exchanges=inflater.inflate(R.layout.exchanges_layout,container,false);
recyclerView=exchanges.findViewById(R.id.rview);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
listItems=new ArrayList<>();
sharedPreferences=new SharedPrefManager(getActivity());
uid = sharedPreferences.getUser().getId();
loadData();
return exchanges;
}
public void loadData() {
StringRequest stringRequest=new StringRequest(Request.Method.GET, URLs.url+uid, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray jsonArray = jsonObject.getJSONArray("data");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject receive = jsonArray.getJSONObject(i);
ExchangesSetterGetter exchangesSetterGetter = new ExchangesSetterGetter(
receive.getString("exchangeFrom"),
receive.getString("exchangeTo"),
receive.getString("status"),
receive.getString("imgSend"),
receive.getString("imgReceive"),
receive.getString("sendCurrency"),
receive.getString("receiveCurrency"),
receive.getString("amount_send"),
receive.getString("amount_receive")
);
listItems.add(exchangesSetterGetter);
}
adapter = new ExchangesAdapter(listItems, getContext());
recyclerView.setAdapter(adapter);
} catch(JSONException e){
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getContext(),"error on volley",Toast.LENGTH_LONG).show();
}
});
RequestQueue queue= Volley.newRequestQueue(getContext());
queue.add(stringRequest);
}
}
You can handle the empty state by having a TextView in your layout, which switch its visibility state depending upon the array size you are getting in your response as:
JSONArray jsonArray = jsonObject.getJSONArray("data");
if (jsonArray.length() > 0) {
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject receive = jsonArray.getJSONObject(i);
ExchangesSetterGetter exchangesSetterGetter = new ExchangesSetterGetter(
receive.getString("exchangeFrom"),
receive.getString("exchangeTo"),
receive.getString("status"),
receive.getString("imgSend"),
receive.getString("imgReceive"),
receive.getString("sendCurrency"),
receive.getString("receiveCurrency"),
receive.getString("amount_send"),
receive.getString("amount_receive")
);
listItems.add(exchangesSetterGetter);
}
adapter = new ExchangesAdapter(listItems, getContext());
recyclerView.setAdapter(adapter);
recyclerView.setVisibilty(View.VISIBLE);
noDataText.setVisibilty(View.GONE);
} else {
recyclerView.setVisiblity(View.GONE);
noDataText.setVisiblity(View.VISIBLE);
}
Add an extra textview in your fragment xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/tv_no_data"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:textSize="22sp"
android:visibility="gone" />
<android.support.v7.widget.RecyclerView
android:id="#+id/rv_ride_list"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
And then in your activity
JSONArray jsonArray = jsonObject.getJSONArray("data");
if(jsonArray.length() > 0){
//process data and initialize adapter
}else{
//Set Text view visible
}
There is a simple solution for that inside your fragment xml where recycler view is being loaded take a relative layout and add a textview with your desired message at last and set it's alignment as per your requirement and inside on create of your fragment set visiblity of your text view to View.INVISIBLE and later on after api is called simply pass an if condition stating that
if(response==null){ textview.setVisiblity = View.Visible}
The way I like to handle this is to wrap your RecyclerView and your NoContentView (this can be whatever you like) in a ViewFlipper like so
<ViewFlipper>
</RecyclerView>
<NoContentView>
</NoContentView>
</ViewFlipper>
Then all you do is to check to see if you have list items and display the appropriate child layout of the ViewFlipper
if(listItems.size() == 0)
{
viewFlipper.setDisplayedChild(1)
}
I have one recycle list view .In this I have one button .on click list view item button shows.On button click I hit one api to perform action .After performing action ,at the bottom of list automatically one item get repeat. when ever I perform api hit action same time items add at the bottom of list .Like as I perform api hit action 4 times then every time one-one item get add at the bottom of list . Please provide me solution to resolve this.

I have an activity named Cardview Activity which has a recycler view associated with it and i am fetching data from a JSON asset file in that.

how can i send the Person_Id, Name and Designation to the People_List_Activity ? Please help as i am stuck in the code.
You can send using Intent , by passing your data in Bundle and then pass Bundle into Intent Extras.When you go form one Activity to another .
Intent intent=new Intent(CardViewActivity.this,PeopleListActivity.class);
Bundle bundle = new Bundle();
bundle.putString("key1",value1);
bundle.putString("key2",value2);
bundle.putString("key3",value3);
intent.putExtras(bundle)
startActvity(intent);
And You can retrieve Data in next Activity OnCreate():
Bundle bundle = getIntent().getExtras();
String value1 = bundle.getString("key1");
String value2 = bundle.getString("key2");
String value3 = bundle.getString("key3");
