i am trying to switch setLayoutManager between LinearLayoutManager(List) to GridLayoutManager(GridView) on toggle button it is working fine but when the layout changes for list to grid its giving me an exception in list view i am showing extra data than girdView and setting texts cant not find this Textviews in gridView single item file so its giving me an error can you please guide how can i handle two layouts and views in single Adapter
this is my Adapter Code

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:

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

grid view items not scrolling down to up (repeating the items) and when i am loading data from server in android?

I have a grid view and data updated in grid view using api calls and grid item loads a image from url using picasso library all are perfect but when i am scrolling down to up the grid items not scrolled and repeating the items(up to down scrolling was perfect).

To avoid the unexpected behaviour , provide the implementations of
#Override
public Object getItem(int position) {
return mProducts.get(position);
}
#Override
public long getItemId(int position) {
//return position; or better to provide some unique id
// as there is one in your code, product id
return mProducts.get(position).prod_id;
}
Note : remove notifyDataSetChanged(); in getView because it will trigger the adapter to refresh all view while they are under creating which can cause this behaviour.

What is the intent of the methods getItem and getItemId in the Android class BaseAdapter?

Listview returning the wrong postion with BaseSwipeAdapter

I am using a listview with swipelayout (daimajia library) and my listview is scrolling...
My problem is when I swipe listview item and click on button in it ,it returns me wrong position..
Do you have any idea of how to solve this??
This is my adapter
public View generateView(final int position, final ViewGroup parent) {
View v =
LayoutInflater.from(parent.getContext()).inflate(R.layout.ledger_layout, null);
SwipeLayout swipeLayout = (SwipeLayout) v.findViewById(getSwipeLayoutResourceId(position));
swipeLayout.addSwipeListener(new SimpleSwipeListener() {
#Override
public void onOpen(SwipeLayout layout) {
}
});
swipeLayout.setOnDoubleClickListener(new
SwipeLayout.DoubleClickListener() {
#Override
public void onDoubleClick(SwipeLayout layout, boolean surface) {
Toast.makeText(context, "DoubleClick",
Toast.LENGTH_SHORT).show();
}
});
return v;
}

I think your implementation of getView method is messy. Try this.

It's been a long time but I had the same issue. It took hours to solve the problem but the solution is here. This WARNING is from the daimajia's wiki.
ATTENTION: Never bind listeners or fill values in generateView. Just generate the view and do everything else in fillValues (e.g using your holder class) See issues #14 and #17
You can find detailed solution here : Solution to your position problem from daimajia's wiki
And sample code is like this :
//ATTENTION: Never bind listener or fill values in generateView.
// You have to do that in fillValues method.
#Override
public View generateView(int position, ViewGroup parent) {
return LayoutInflater.from(mContext).inflate(R.layout.grid_item, null);
}
#Override
public void fillValues(int position, View convertView) {
TextView t = (TextView)convertView.findViewById(R.id.position);
t.setText((position + 1 )+".");
}
You should do everything in fillValues() function. position value here is always right.
Just follow this rule and everything will be fine with your Swipe ListView.

RecyclerView not displaying any data

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

});
int count = offerRecyclerAdapter.getItemCount();
offerRecyclerAdapter.notifyDataSetChanged();
}

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) {
}
});
}

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.
