RecyclerView not displaying any data

RecyclerView not displaying any data - android

In my Application I m having a RecyclerView in one of my Fragments in which I am getting response from a server using Reterofit. Every thing is fine but My RecylerView is not displaying any data returned from my service. Even the
int count = offerRecyclerAdapter.getItemCount();
of my adapter is returning the correct amount of data count returned from server.
Inside Fragment:
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
offersRecyclerView = (RecyclerView) view.findViewById(R.id.offer_recycler);
MotorCityArabiaGlobal global = (MotorCityArabiaGlobal) getActivity().getApplication();
ApiInterface apiService=global.getClient().create(ApiInterface.class);
Call<OfferResponse> call = apiService.getOffers(4);
call.enqueue(new Callback<OfferResponse>() {
#Override
public void onResponse(Call<OfferResponse> call, Response<OfferResponse> response) {
OfferResponse offers = response.body();
if(offers!=null){
List<Offer> result = response.body().getResult();
offerRecyclerAdapter = new OffersAdapter(getActivity(),result);
offersRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
offersRecyclerView.setItemAnimator(new DefaultItemAnimator());
offersRecyclerView.addItemDecoration(new DividerItemDecoration(getActivity(), LinearLayoutManager.VERTICAL));
offersRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
#Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
return false;
}
#Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
#Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
});
int count = offerRecyclerAdapter.getItemCount();
offerRecyclerAdapter.notifyDataSetChanged();
}
}
#Override
public void onFailure(Call<OfferResponse> call, Throwable t) {
}
});
}
Adapter Class:
public class OffersAdapter extends RecyclerView.Adapter<OffersAdapter.MyViewHolder> {
private List<Offer> offersList= Collections.emptyList();
private LayoutInflater inflater;
Context ctx;
public OffersAdapter(Context ctx,List<Offer> offersList) {
this.ctx = ctx;
this.inflater = LayoutInflater.from(ctx);
this.offersList = offersList;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// View view = LayoutInflater.from(parent.getContext())
// .inflate(R.layout.offer_list_layout, parent, false);
View view = inflater.inflate(R.layout.offer_list_layout,parent,false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Offer offer = offersList.get(position);
holder.title.setText(offer.getOffer_title());
holder.price.setText(offer.getPrice());
holder.offerCount.setText(offer.getOffer_count());
}
#Override
public int getItemCount() {
return offersList.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title, offerCount, price;
public ImageView image;
public MyViewHolder(View view) {
super(view);
title = (TextView) view.findViewById(R.id.title);

add the line below in your onResponse after offersRecyclerView.addItemDecoration();
offersRecyclerView.setAdapter(offerRecyclerAdapter);
hope this helps.

You did not set the adapter to the RecyclerView. Use setAdapter method. See the following code,
List<Offer> results = new ArrayList<Offer>();
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
offersRecyclerView = (RecyclerView) view.findViewById(R.id.offer_recycler);
offersRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
offersRecyclerView.setItemAnimator(new DefaultItemAnimator());
offersRecyclerView.addItemDecoration(new DividerItemDecoration(getActivity(), LinearLayoutManager.VERTICAL));
offerRecyclerAdapter = new OffersAdapter(getActivity(), results)
offersRecyclerView.setAdapter(offerRecyclerAdapter);
offersRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
#Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
return false;
}
#Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
#Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
});
MotorCityArabiaGlobal global = (MotorCityArabiaGlobal) getActivity().getApplication();
ApiInterface apiService=global.getClient().create(ApiInterface.class);
Call<OfferResponse> call = apiService.getOffers(4);
call.enqueue(new Callback<OfferResponse>() {
#Override
public void onResponse(Call<OfferResponse> call, Response<OfferResponse> response) {
OfferResponse offers = response.body();
if(offers != null){
List<Offer> result = response.body().getResult();
results.clear();
results.addAll(result);
offerRecyclerAdapter.notifyDataSetChanged();
}
}
#Override
public void onFailure(Call<OfferResponse> call, Throwable t) {
}
});

How to fetch data related to a clicked item in a recyclerView from room database to a new activity?

My app has a RawMaterialFragment that displays raw materials data in a recyclerView from room database.
I am trying to build a detail activity(MetrialItemView) to show up the details of an individual raw material by clicking or selecting the raw material from the recyclerView.
my problem is how to send the data from the adapter and how to receive the data in the MetrialItemView Activity and display it.
MaterialListAdapter:
public class MaterialListAdapter extends RecyclerView.Adapter<MaterialListAdapter.ViewHolder> {
private final LayoutInflater mInflater;
private FragmentRawMaterials mContext;
private List<RawMaterialsEntity> mMaterial; // Cached copy of Materials
RawMaterialsEntity mCurrent;
public MaterialListAdapter(FragmentRawMaterials context) {
mInflater = LayoutInflater.from(context.getActivity());
mContext = context;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = mInflater.inflate(R.layout.list_item, parent, false);
return new ViewHolder(itemView);
}
public class ViewHolder extends RecyclerView.ViewHolder {
private final TextView materialName;
private final TextView materialBrand;
private final TextView materialQuantity;
LinearLayout parentLayout;
private ViewHolder(View itemView) {
super(itemView);
materialName = itemView.findViewById(R.id.raw_material_name);
materialBrand = itemView.findViewById(R.id.raw_material_brand);
materialQuantity = itemView.findViewById(R.id.raw_material_quantity);
parentLayout = itemView.findViewById(R.id.parent_layout);
}
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
if (mMaterial != null) {
mCurrent = mMaterial.get(position);
holder.materialName.setText(mCurrent.getRawMaterialName());
holder.materialBrand.setText(mCurrent.getRawMaterialBrand());
holder.materialQuantity.setText(String.valueOf(mCurrent.getRawMaterialQuantity()));
} else {
// Covers the case of data not being ready yet.
holder.materialName.setText("Name NA");
holder.materialBrand.setText("Brand NA");
holder.materialQuantity.setText("Quantity NA");
}
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(mContext.getContext(), MaterialItemView.class);
mContext.startActivity(intent);
}
});
}
public void setMaterial(List<RawMaterialsEntity> materials){
mMaterial = materials;
notifyDataSetChanged();
}
// getItemCount() is called many times, and when it is first called,
// mWords has not been updated (means initially, it's null, and we can't return null).
#Override
public int getItemCount() {
if (mMaterial != null)
return mMaterial.size();
else return 0;
}
}
MaterialItemView:
public class MaterialItemView extends AppCompatActivity {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.material_item_view);
}
}

}

each row of dataModel() must have ID and then use putExtra() whan clicked It happens
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(mContext.getContext(), MaterialItemView.class);
intent.putExtra("ID",mCurrent.getID());
mContext.startActivity(intent);
}
});
and use getIntent() in detailActivity
int id =getIntent().getIntExtra("ID",-1);
and then get a row data in detail activity from database(viewModel)by ID and parse it

}

I think the problem is that you are not adding the elements to the adapter. You need to have a method in the adapter to add items after the adapter has been created. Inside that method you need to notify. Example:
void addItems(List<CarItem> carItems){
Array_cars.addAll(carItems);
notifyDataSetChanged();
}
However, I would go a bit far and find the number of items and try to notify only for the newly inserted ones(in case there is something already).
This can be done like this:
void addItems(List<CarItem> carItems){
int position = Array_cars.size();
Array_cars.addAll(carItems);
notifyItemRangeChanged(position, Array_cars.size() - position);
}
EDIT
Look at this example below:
RecycleView

Here is the xml layout for the recyclerview activity
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"

<RelativeLayout
android:id="#+id/relativeLayout"

android:layout_width="match_parent"
android:layout_height="match_parent"

You have added match_parent height of "RecyclerView" please change to wrap_content.

Did you try to set it as clicable and focusable?
XML
android:focusable="true"
android:clickable="true"
Java
button.setClickable("true");
button.setFocusable("true");
If nothing changes, try to put a log call in your onClick method (maybe there's something bad in the code), or in OnTouch.

Next item appearing after scolling in RecyclerView

I have created RecyclerView. When it renders on screen it shows only one item per screen. I can see next item when I scroll down RecyclerView. Here is my code
public class LeaveStatusViewAdapter extends RecyclerView
.Adapter<LeaveStatusViewAdapter
.DataObjectHolder> {
private static String LOG_TAG = "MyRecyclerViewAdapter";
private ArrayList<Employee> mDataset;
private static MyClickListener myClickListener;
public static class DataObjectHolder extends RecyclerView.ViewHolder
implements View
.OnClickListener {
TextView startDate;
TextView endDate;
TextView leaveType;
TextView leaveDays;
TextView leaveReason;
TextView leaveStatus;
public DataObjectHolder(View itemView) {
super(itemView);
startDate = (TextView) itemView.findViewById(R.id.textView_StartDate);
endDate = (TextView) itemView.findViewById(R.id.textView_EndDate);
leaveType = (TextView) itemView.findViewById(R.id.textView_LeaveType);
leaveDays = (TextView) itemView.findViewById(R.id.textView_LeaveDays);
leaveReason = (TextView) itemView.findViewById(R.id.textView_LeaveReason);
leaveStatus = (TextView) itemView.findViewById(R.id.textView_LeaveStatus);
Log.i(LOG_TAG, "Adding Listener");
itemView.setOnClickListener(this);
}
#Override
public void onClick(View v) {
myClickListener.onItemClick(getAdapterPosition(), v);
}
}
public void setOnItemClickListener(MyClickListener myClickListener) {
this.myClickListener = myClickListener;
}
public LeaveStatusViewAdapter(ArrayList<Employee> myDataset) {
mDataset = myDataset;
}
#Override
public DataObjectHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.card_view_row, parent, false);
DataObjectHolder dataObjectHolder = new DataObjectHolder(view);
return dataObjectHolder;
}
#Override
public void onBindViewHolder(DataObjectHolder holder, int position) {
holder.startDate.setText(mDataset.get(position).getLeaveStartDate());
holder.endDate.setText(mDataset.get(position).getLeavesEndDate());
holder.leaveType.setText(mDataset.get(position).getLeaveType());
holder.leaveDays.setText(mDataset.get(position).getLeaveDays());
holder.leaveReason.setText(mDataset.get(position).getLeaveReason());
holder.leaveStatus.setText(mDataset.get(position).getLeaveStatus());
}
public void addItem(Employee dataObj, int index) {
mDataset.add(index, dataObj);
notifyItemInserted(index);
}
public void deleteItem(int index) {
mDataset.remove(index);
notifyItemRemoved(index);
}
#Override
public int getItemCount() {
return mDataset.size();
}
public interface MyClickListener {
public void onItemClick(int position, View v);
}
}
Following is activity class
public class LeaveStatusActivity extends AppCompatActivity {
private RecyclerView mRecyclerView;
private RecyclerView.Adapter mAdapter;
private RecyclerView.LayoutManager mLayoutManager;
private static String LOG_TAG = "CardViewActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_leave_status);
mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);
mAdapter = new LeaveStatusViewAdapter(getDataSet());
mRecyclerView.setAdapter(mAdapter);
}
#Override
protected void onResume() {
super.onResume();
((LeaveStatusViewAdapter) mAdapter).setOnItemClickListener(new LeaveStatusViewAdapter
.MyClickListener() {
#Override
public void onItemClick(int position, View v) {
Log.i(LOG_TAG, " Clicked on Item " + position);
}
});
}
private ArrayList<Employee> getDataSet() {
ArrayList results = new ArrayList<Employee>();
for (int index = 0; index < 3; index++) {
Employee obj = new Employee(" : 15/07/2016",
" : 20/07/2016"," : EL: Earned Leave"," : 5"," : Not feeeling well"," : Pending");
results.add(index, obj);
}
return results;
}
}
Following is Layout files

Am I missing something here??

You should change the view of each element of the list to android:layout_height="wrap_content"
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.CardView
android:id="#+id/card_view"
android:layout_gravity="center"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp">
.....
</LinearLayout>
When you use android:layout_height="match_parent" every item of the list will try to use the maximum space possible in the screen
