How can I hide an ImageView on my RecyclerView for certain items based on a particular condition?

I have a RecyclerView with an ImageView being a part of the items. I want to hide the ImageView from an item in the RecyclerView if a certain condition is met. How can I do that? I am attaching the image of how I want it to look like.
I am just defining the ImageViews in my xml layout file, so I cannot figure out how to actually remove it based on a certain condition in my android activity. I am attaching the code for the adapter class and my activity as well.
Here is the code for my adapter class
Adapter Class
public class ReportAdapter extends RecyclerView.Adapter<ReportAdapter.ReportViewHolder> {
private ArrayList<ReportItem> reportlist;
private OnItemClickListener mListener;
private Context mContext;
public ReportAdapter(ArrayList<ReportItem> reportlist, Context context) {
this.reportlist = reportlist;
this.mContext = context;
}
public interface OnItemClickListener {
void onItemClick(int position);
}
public void setOnItemClickListener(OnItemClickListener listener) {
mListener = listener;
}
public static class ReportViewHolder extends RecyclerView.ViewHolder {
public TextView departureDate;
public TextView flightNumber;
public View relativelayout;
public ReportViewHolder(#NonNull View itemView, OnItemClickListener listener, Context context) {
super(itemView);
departureDate = itemView.findViewById(R.id.departureDaterecyclerview);
flightNumber = itemView.findViewById(R.id.flightnumberrecyclerview);
relativelayout = itemView.findViewById(R.id.relativeLayoutReports);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(listener != null) {
int position = getAdapterPosition();
if(position != RecyclerView.NO_POSITION) {
listener.onItemClick(position);
}
}
}
});
}
}
#NonNull
#Override
public ReportViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.report_listing_item, parent, false);
ReportViewHolder rvh= new ReportViewHolder(v,mListener,mContext);
return rvh;
}
#SuppressLint("ResourceAsColor")
#Override
public void onBindViewHolder(#NonNull ReportViewHolder holder, int position) {
ReportItem currentItem = reportlist.get(position);
if(position%2==0){
holder.relativelayout.setBackgroundColor(mContext.getResources().getColor(R.color.reportlistingteal));
} else {
holder.relativelayout.setBackgroundColor(mContext.getResources().getColor(R.color.reportlistinglightteal));
}
holder.departureDate.setText((currentItem.getDepartureDate()));
holder.flightNumber.setText(currentItem.getFlightNumber());
}
Here is the code for my activity file
Activity file
public class ReportListingActivity extends AppCompatActivity {
private Button uploadAllBtn;
private EditText searchFlights;
private RecyclerView mRecyclerView;
private ReportAdapter mAdapter;
private RecyclerView.LayoutManager mLayoutManager;
ArrayList<ReportItem> reportitems = new ArrayList<>();
private FlightViewModel flightViewModel;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_report_listing);
uploadAllBtn = findViewById(R.id.uploadAllReports);
searchFlights = findViewById(R.id.searchFlightText);
mRecyclerView = findViewById(R.id.recyclerView);
flightViewModel = new ViewModelProvider(this).get(FlightViewModel.class);
flightViewModel.getAllFlights().observe(this, new Observer<List<Flight>>() {
#Override
public void onChanged(List<Flight> flight_list) {
if (flight_list.size() == 0) return;
String flightno = flight_list.get(0).getFlightNumber();
String flightdate = flight_list.get(0).getDate();
String[] flight_details = new String[2];
flight_details[0]= flightno;
flight_details[1] = flightdate;
Log.v("pp", flight_details[0]);
for(int i = 0; i <flight_list.size();i++){
String flightnumber = flight_list.get(i).getFlightNumber();
String departuredate = flight_list.get(i).getDate();
reportitems.add(new ReportItem(flightnumber,departuredate));
}
mRecyclerView.getAdapter().notifyDataSetChanged();
flightViewModel.getAllFlights().removeObservers(ReportListingActivity.this);
}
});
mLayoutManager = new LinearLayoutManager(ReportListingActivity.this);
mAdapter = new ReportAdapter(reportitems, ReportListingActivity.this);
mRecyclerView.setLayoutManager(mLayoutManager);
mRecyclerView.setAdapter(mAdapter);
}
Report Item
public class ReportItem {
private String departureDate;
private String flightNumber;
public ReportItem(String departureDate, String flightNumber) {
this.departureDate = departureDate;
this.flightNumber = flightNumber;
}
public String getDepartureDate() {
return departureDate;
}
public String getFlightNumber() {
return flightNumber;
}
}

Add a boolean flag to your ReportItem class for each RecyclerView item. You will need to specify which rows show or hide this field when each item is created:
public class ReportItem {
private String departureDate;
private String flightNumber;
private Boolean showMailIcon;
public ReportItem(String departureDate, String flightNumber, Boolean showMailIcon) {
this.departureDate = departureDate;
this.flightNumber = flightNumber;
this.showMailIcon = showMailIcon
}
public String getDepartureDate() {
return departureDate;
}
public String getFlightNumber() {
return flightNumber;
}
public String getShowMailIcon() {
return showMailIcon;
}
}
Then update the onBindViewHolder() method override to use this flag to show/hide the ImageView:
#Override
public void onBindViewHolder(#NonNull ReportViewHolder holder, int position) {
ReportItem currentItem = reportlist.get(position);
if (currentItem.getShowMailIcon() == true) {
holder.mailIcon.setVisibility(View.VISIBLE);
} else {
holder.mailIcon.setVisibility(View.GONE);
}
//.......
}

RecyclerView: different ViewType by different button

I have a recycler view to show an activity timeline and three floating buttons that click to add activity. How can I code three buttons to a different view? How can I pass the condition to the Adapter?
Now I can show only one viewType.
thx a lot.

My application I adapt from codinginflow channel.

There is no compilation error but when running the code clicking the comment button, it is not leading to the activity I want

I did the code below, used the adapter to show the list, and a button to add a comment to list item, it shows the logcat "ViewPostIme pointer 0 and ViewPostIme pointer 1", upon clicking the comment button.
Upon compilation it doesn't show any error, I tried to use many references via google but nothing works out.
My basic idea is to call the comment button with an associated list item to perform the comment activity.

Can't get int or double to display on RecyclerView after parsing json

When I just display string data it seems to show up fine, but when I try to display an int or double the RecyclerView won't populate. I am pulling from the Google places API JSON. I think maybe it is the way I'm using my onBindViewHolder()? Thanks
// MainActivity
private void getJson() {
String URL = https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=40.7085,-74.003124&opennow&radius=5000&type=restaurant&key=
JsonObjectRequest root = new JsonObjectRequest(Request.Method.GET, URL, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray results = response.getJSONArray("results");
Log.d("RESULTS", String.valueOf(results));
for(int i = 0; i<results.length(); i++) {
JSONObject resultsObj = results.getJSONObject(i);
mImageUrls.add(resultsObj.getString("icon"));
mTitle.add(resultsObj.getString("name"));
//mRating.add(resultsObj.getDouble("rating"));
mPriceLevel.add(resultsObj.getInt("price_level"));
}
getRecyclerView();
} catch (JSONException e) {
e.printStackTrace();
}
}
},new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
mRequestQueue.add(root);
}
private void getRecyclerView() {
// LinearLayoutManager
recyclerView = findViewById(R.id.recyclerView);
adapter = new RecyclerViewAdapter(mImageUrls, mTitle, mPriceLevel, this);
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
}
And the RecyclerViewAdapter Class is.
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>{
private static final String TAG = "RecyclerViewAdapter";
private ArrayList<String> rNames = new ArrayList<>();
private ArrayList<String> rImageUrls = new ArrayList<>();
private ArrayList<Double> rRatings = new ArrayList<>();
private ArrayList<Integer> rPriceLevel = new ArrayList<>();
private Context mContext;
public RecyclerViewAdapter(ArrayList<String> image, ArrayList<String> name, ArrayList<Integer> priceLevel, Context context) {//, ArrayList<Double> rating
this.rImageUrls = image;
this.rNames = name;
//this.rRatings = rating;
this.rPriceLevel = priceLevel;
mContext = context;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_item, parent, false);
ViewHolder holder = new ViewHolder(view);
return holder;
//return new ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, final int position) {
Glide.with(mContext).asBitmap().load(rImageUrls.get(position)).into(holder.image);
holder.name.setText(rNames.get(position));
//holder.rating.setText(rRatings.get(position));
holder.priceLevel.setText(rPriceLevel.get(position));
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d(TAG, "onClick: clicked on an image: " + rNames.get(position));
Toast.makeText(mContext, rNames.get(position), Toast.LENGTH_SHORT).show();
}
});
}
#Override
public int getItemCount() {
return rNames.size(); //we can use rImageUrls/rRatings as well because they are all the same size
}
public class ViewHolder extends RecyclerView.ViewHolder{
ImageView image;
TextView name;
TextView rating;
TextView priceLevel;
TextView address;
RelativeLayout parentLayout;
public ViewHolder(View itemView) {
super(itemView);
image = (ImageView) itemView.findViewById(R.id.image);
name = (TextView) itemView.findViewById(R.id.title);
//rating = itemView.findViewById(R.id.rating);
priceLevel = (TextView) itemView.findViewById(R.id.priceLevel);
parentLayout = itemView.findViewById(R.id.parentLayout);
}
}
}

The reason for this is you are not converting Double to String
change this line holder.rating.setText(rRatings.get(position)); to holder.rating.setText(String.valueOf(rRatings.get(position)));

I would like to suggest you to create an object having all necessary parameters in it and then pass a single list of that object to the RecyclerViewAdapter.
public class MapElement {
public String name;
public String imageUrl;
public Double rating;
public Integer price;
}
Then create an ArrayList of this object when you get the response from your getJson function call. Now in your adapter just use a single list of MapElement object to show the data from there.
The modified adapter should look like this.
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>{
private static final String TAG = "RecyclerViewAdapter";
private ArrayList<MapElement> elements = new ArrayList<>();
private Context mContext;
public RecyclerViewAdapter(ArrayList<MapElement> elements, Context context) {
this.elements = elements;
mContext = context;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_item, parent, false);
ViewHolder holder = new ViewHolder(view);
return holder;
}
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, final int position) {
Glide.with(mContext).asBitmap().load(rImageUrls.get(position)).into(holder.image);
holder.name.setText(elements.get(position).name);
holder.rating.setText(elements.get(position).rating);
holder.priceLevel.setText(elements.get(position).price);
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d(TAG, "onClick: clicked on an image: " + rNames.get(position));
Toast.makeText(mContext, elements.get(position).name, Toast.LENGTH_SHORT).show();
}
});
}
#Override
public int getItemCount() {
return elements.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
ImageView image;
TextView name;
TextView rating;
TextView priceLevel;
TextView address;
RelativeLayout parentLayout;
public ViewHolder(View itemView) {
super(itemView);
image = (ImageView) itemView.findViewById(R.id.image);
name = (TextView) itemView.findViewById(R.id.title);
rating = itemView.findViewById(R.id.rating);
priceLevel = (TextView) itemView.findViewById(R.id.priceLevel);
parentLayout = itemView.findViewById(R.id.parentLayout);
}
}
}

First you should check that the rating you are getting is a double value.
It might be the case that an exception is thrown after this line
mRating.add(resultsObj.getDouble("rating"))
Also as #hooray_todd siggested textview only takes string value so you have to change your data into string.

get and set global variables from CustomListViewAdapter

Am looking to create a fragment conaining listview by retriveing data from firebase database.This listview gets cards having buttons and seekbar. All I want is to have a global variable listen to these buttons. I tried creating onClicklistener in the fragment itself but wasn't successful.Then I created onClicklistener for these buttons on the Adapter itself which was working. Now when I use the buttonclick to create a Toast, the Toast string is coming up as I expect. But the problem is that I want this Toasted string to store somewhere like global variable so that I could use it in another fragment as well. So I used:
String alpha = ((MyApplication) getContext()).getCartitem();
((MyApplication)getContext()).setCartitem("XYZ");
inside my adapter class's on Click Listener itself but the application crashes showing error log "First cannot be cast to com.fastfrooot.fastfrooot.MyApplication". First being my Activity containing Fragment and MyApplication is the class extending application.
