So I have a CardView in a RecyclerView which has some data inside it. I would like to click on a specific card and launch a new fragment that displays specific data from the data in the CardView (more details about the data in the CardView). Here is the relevant code.
I don't have the most experience in programming and Android in general, any help would be appreciated!
DetailsFragment: `
public class DetailsFragment extends Fragment {
private CardView cardView;
private RecyclerView rv;
private List<Detail> detailList = new ArrayList<>();
public DetailsFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_details, container, false);
Context context = getActivity();
cardView = (CardView) rootView.findViewById(R.id.cv);
rv = (RecyclerView) rootView.findViewById(R.id.rv);
final LinearLayoutManager llm = new LinearLayoutManager(context);
rv.setLayoutManager(llm);
RVDetailAdapter adapter = new RVDetailAdapter(detailList);
rv.setAdapter(adapter);
initializeData();
initializeAdapter();
return rootView;
}
private void initializeData() {
detailList = new ArrayList<>();
// not sure here
detailList.add(new Detail(" "));
}
private void initializeAdapter(){
RVDetailAdapter adapter = new RVDetailAdapter(detailList);
rv.setAdapter(adapter);
}
}
RVNewsAdapater:
public class RVNewsAdapter extends RecyclerView.Adapter<RVNewsAdapter.NewsViewHolder> {
public static final String KEY_LINK ="link";

Not sure if you're still looking for an answer, but I just saw the post and thought I'd give you one option.
When I'm using a RecyclerView (doesn't matter if it's using the CardView or not, it's the same for any list item), I create a a click listener for the view item in the Adapter. When the user clicks the item/cardview, I dispatch an item click event. It's your choice on how you respond - you can use a standard callback interface (and pass in your listener when you create the adapter) or use something like EventBus.
Here's an example of the code you would add to your adapter class:
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(itemLayout, parent, false);
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
itemClick(view);
}
});
return new ViewHolder(view);
}
private void itemClick(View view) {
//Handle item event here
//EventBus.getDefault().post(new ItemSelectedEvent(/*send apprpopriate data*/));
}

I have a nested recyclerview to show the list of foods in each category. When the user clicks the increase or decrease button, the quantity will be updated to the quantity textview and synced to the cart stored in the database, but currently I don't know how to listen for the event when the user clicks these buttons.
Here is my current UI when run:
enter image description here
Here is my fragment:
public class TabOrderFragment extends Fragment {
private static final String ARG_RESTAURANT_ID = "restaurantId";
private int restaurantId;
View view;
RecyclerView menuRecyclerView;
RecyclerView.LayoutManager layoutManager;
ArrayList<Menu> menuArrayList;
MenuAdapter menuAdapter;
public TabOrderFragment() { }
public static TabOrderFragment newInstance(int restaurantId) {
TabOrderFragment fragment = new TabOrderFragment();
Bundle args = new Bundle();
args.putInt(ARG_RESTAURANT_ID, restaurantId);
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
restaurantId = getArguments().getInt(ARG_RESTAURANT_ID);
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.fragment_tab_order, container, false);
if(restaurantId != 0) {
DatabaseHandler databaseHandler = DatabaseHandler.getInstance(getActivity());
menuArrayList = new ArrayList<Menu>();
menuArrayList = databaseHandler.getAllMenuFoodsByIdRestaurant(restaurantId);
menuRecyclerView = view.findViewById(R.id.rcv_foods_menu);
menuAdapter = new MenuAdapter(getActivity().getApplicationContext(), restaurantId);
layoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false);
menuRecyclerView.setLayoutManager(layoutManager);
menuAdapter.setData(menuArrayList);
menuRecyclerView.setAdapter(menuAdapter);
}
return view;
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
Log.d("TabOrderFragment", "Restaurant Id = " + restaurantId);
}
Here is my MenuAdapter:
public class MenuAdapter extends RecyclerView.Adapter<MenuAdapter.MenuViewHolder> {
Context context;
private int restaurantId;
private RecyclerView.RecycledViewPool viewPool = new RecyclerView.RecycledViewPool();
ArrayList<Menu> menuList;
public MenuAdapter(ArrayList<Menu> menuList) {
this.menuList = menuList;
}
public MenuAdapter(Context context, int restaurantId) {
this.context = context;
this.restaurantId = restaurantId;
}
public void setData(ArrayList<Menu> menuList) {
this.menuList = menuList;
notifyDataSetChanged();
}
#NonNull
#Override
public MenuViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_foods_menu, parent, false);
return new MenuViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MenuViewHolder holder, int position) {
Menu menu = menuList.get(position);
holder.txtMenuTitle.setText(menu.getTitle().concat(" (" + String.valueOf(menu.getQuantity()) + ")"));
LinearLayoutManager layoutManager = new LinearLayoutManager(holder.rcvListFoods.getContext(), LinearLayoutManager.VERTICAL, false);
layoutManager.setInitialPrefetchItemCount(menu.getFoods().size());
FoodAdapter foodAdapter = new FoodAdapter(menu.getFoods(), restaurantId);
holder.rcvListFoods.setLayoutManager(layoutManager);
holder.rcvListFoods.setAdapter(foodAdapter);
holder.rcvListFoods.setRecycledViewPool(viewPool);
}
#Override
public int getItemCount() {
if(menuList != null) {
return menuList.size();
}
return 0;
}
public class MenuViewHolder extends RecyclerView.ViewHolder {
private TextView txtMenuTitle;
private RecyclerView rcvListFoods;
public MenuViewHolder(#NonNull View itemView) {
super(itemView);
txtMenuTitle = itemView.findViewById(R.id.txv_menu_title);
rcvListFoods = itemView.findViewById(R.id.rcv_list_foods);
}
}
}
Here is my FoodAdapter:
public class FoodAdapter extends RecyclerView.Adapter<FoodAdapter.FoodViewHolder> {
private ArrayList<Food> foodList;
private int restaurantId;
private int userId;
SharedPreferences sharedPreferences;
public FoodAdapter(ArrayList<Food> foodList, int restaurantId) {
this.foodList = foodList;
this.restaurantId = restaurantId;
}
#NonNull
#Override
public FoodViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
sharedPreferences = fragmentActivity.getSharedPreferences("currentUser", Context.MODE_PRIVATE);
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_food, parent, false);
return new FoodViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull FoodViewHolder holder, int position) {
Food food =foodList.get(position);
Picasso.get().load(food.getThumbImage()).into(holder.foodThumbImage);
holder.foodName.setText(food.getName());
holder.foodDescription.setText(food.getDescription());
double price = Double.parseDouble(food.getPrice());
DecimalFormat formatter = new DecimalFormat("#,###");
holder.foodPrice.setText(formatter.format(price) + "đ");
}
#Override
public int getItemCount() {
if(foodList != null) {
return foodList.size();
}
return 0;
}
public class FoodViewHolder extends RecyclerView.ViewHolder {
private ImageView foodThumbImage;
private TextView foodName;
private TextView foodDescription;
private TextView foodPrice;
private TextView quantity;
private MaterialButton increaseBtn;
private MaterialButton decreaseBtn;
private ItemClickListener itemClickListener;
public FoodViewHolder(#NonNull View itemView) {
super(itemView);
foodThumbImage = itemView.findViewById(R.id.image_food);
foodName = itemView.findViewById(R.id.txv_food_name);
foodDescription = itemView.findViewById(R.id.txv_food_description);
foodPrice = itemView.findViewById(R.id.txv_food_price);
quantity = itemView.findViewById(R.id.txv_quantity);
increaseBtn = itemView.findViewById(R.id.btn_increase);
decreaseBtn = itemView.findViewById(R.id.btn_decrease);
}
}
in your food adapter's onBindViewHolder method use
holder.increaseBtn.setOnClickListener{
onIncreaseClick()
}
while create an interface like
interface Listener{
public void onIncreaseClick();
public void onDecreaseClick();
}
and implement your interface in your activity or fragment or viewmodel where you can listen for the click event
What you can do generally when you have something like that, is to create an interface for the interaction with the Recycler view:
interface Interaction {
public void onFoodClick(Food food)
}
Then you add an instance of this interface in your recycler view adapter, and you let your activity or fragment implement this interface, please find a good explanation here: https://stackoverflow.com/a/31671289/7334951
In my MainActivity.java I have a sort of button to login. I also have 4 fragments, each of them containing a recycler view (imageview + textview).
The imageview is hidden, but when I press the button it becomes visibile. How can I do that? The notifyDataSetChanged() doesn't work in the adapter and I can't call it on the adapter in the fragment page, because is outside the onCreateView method.
Here's my code:
MainActivity: contains the button
Fragment Page:
public class Classici_Tab extends Fragment {
LinkedList<Book> catalog = new LinkedList<>();
RecyclerView mRecyclerView;
BookListAdapter mAdapter;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View fragmentView = inflater.inflate(R.layout.classici_tab, container, false);
fillCatalog("catalog.csv"); //fill the LinkedList
mRecyclerView = (RecyclerView) fragmentView.findViewById(R.id.classici_rv);
mAdapter = new BookListAdapter(getContext(), catalog);
mRecyclerView.setAdapter(mAdapter);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
return fragmentView;
}
}
Adapter:
public class BookListAdapter extends RecyclerView.Adapter<BookListAdapter.BookViewHolder> {
// View Holder
class BookViewHolder extends RecyclerView.ViewHolder
{
public final ImageView cover;
public final TextView title;
public final TextView author;
public final ImageView availability;
final BookListAdapter mAdapter;
public BookViewHolder(View itemView, BookListAdapter adapter) {
super(itemView);
cover = (ImageView) itemView.findViewById(R.id.cover);
title = (TextView) itemView.findViewById(R.id.title);
author = (TextView) itemView.findViewById(R.id.author);
availability = (ImageView) itemView.findViewById(R.id.availability);
MainActivity m = new MainActivity();
if(m.loggedin) availability.setVisibility(View.VISIBLE);
else availability.setVisibility(View.INVISIBLE);
this.mAdapter = adapter;
}
}
private LinkedList<Book> mBookList = new LinkedList<>();
private LayoutInflater mInflater;
boolean isVisible = false;
public BookListAdapter() {}
public BookListAdapter(Context context, LinkedList<Book> bookList) {
mInflater = LayoutInflater.from(context);
this.mBookList = bookList;
}
//IT DOESN'T WORK
public void setPicturesVisibility(boolean isVisible){
this.isVisible = true;
notifyDataSetChanged();
}
#Override
public BookViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View mItemView = mInflater.inflate(R.layout.tab_list_item, parent, false);
return new BookViewHolder(mItemView, this);
}
#Override
public void onBindViewHolder(BookViewHolder holder, int position) {
holder.cover.setImageResource(mBookList.get(position).getCover());
holder.title.setText(mBookList.get(position).getTitle());
holder.author.setText(mBookList.get(position).getAuthor());
holder.availability.setImageResource(mBookList.get(position).getAvailability());
if(isVisible){
holder.availability.setVisibility(View.VISIBLE);
}else{
holder.availability.setVisibility(View.INVISIBLE);
}
}
#Override
public int getItemCount() {
return mBookList.size();
}
}
Not sure why you need to recreate adapter. Without recreating adapter, you can add listener to the button and in the onclick event handler, make image visible in recyclerview adapter's viewholder constructor.
public ViewHolder(View view) {
super(view);
textview = view.findViewById(R.id.textview);
imgView = view.findViewById(R.id.storeImg);
Button button = (Button) view.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
imgView.setVisibility(View.VISIBLE);
}
});
}
You can find recyclerview examples here http://www.zoftino.com/android
There is no need to recreate adapter. You can add a boolean arePicturesVisible = false; in your RecyclerViewAdapter.
And make a method in adapter:
public void setPicturesVisibility(boolean areVisible){
arePicturesVisible = areVisible;
notifyDataSetChanged();
}
Then add:
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
.....
if(arePicturesVisible){
holder.image.setVisibility(View.VISIBLE);
}else{
holder.image.setVisibility(View.INVISIBLE);
}
.....
}
Then in your button onClick() method call setPicturesVisibility() from RecyclerView adapter.
I have two tabs (fragments), NewOrders and FinishedOrders, I'm populating the orders via Volley requests, now each item inside the New Orders tab has a SwipeLayout which show a clickable textview that makes the order finished, and move it to the other tab (backend stuff..), and I got this working perfectly,
The problem is when I click to finish, the recyclerview isn't updated once the request sent successfully, I have to do pull-to-refresh so it would update..! it seems easy to solve, but the issue is handling the swipelayout listener done inside onBindView method inside the adapter..!! that's only place to access it according to the library I'm using (I guess)..! on the other hand refreshing and populating the list happens in the NewOrder tab fragment..!
So how can I make the item to be removed from the list after the click and becomes updated..?!
Any thoughts..!?
My Adapter Class + ViewHolder
Note: the implemented methods in the adapter are required because of the interface of SwipeLayout library

vh1.swipeLayout.setShowMode(SwipeLayout.ShowMode.PullOut);
vh1.swipeLayout.addDrag(SwipeLayout.DragEdge.Left,
vh1.swipeLayout.findViewById(R.id.bottom_wrapper));
if (order.isFinished()) {
vh1.swipeLayout.setSwipeEnabled(false);
vh1.setBadge("DONE");
vh1.setBadgeColor(order.getBadgeColor());
} else {
vh1.finish.setOnClickListener(new View.OnClickListener() {
#Override

// get the clicked item position?
final int position = vh1.getAdapterPosition();
// these responsible for the request which make the order finished
OrderPresenter order = orders.get(position);

OrderRepository.FinishOrder(order.getID(), context);
/*the commented three lines below didn't help with the problem*/

My NewOrder Fragment
Note: the FinishedOrders tab (fragment) does the same thing as new order but filters the current the Finished status.

private SwipeRefreshLayout swiperefresh;
private TextView emptyView;
ArrayList<OrderPresenter> modelData;
#Override

recyclerView.setAdapter(adapter);
adapter.setMode(Attributes.Mode.Single);
OrderRepository.fetchOrders("awaiting-shipment", getActivity(), new DataFetch() {
#Override
public void onResponse(ArrayList<OrderPresenter> data) {
swiperefresh.setRefreshing(true);
if (data.size() != 0) {
swiperefresh.setRefreshing(true);
emptyView.setVisibility(View.GONE);
modelData.clear();
modelData.addAll(data);
adapter.notifyDataSetChanged();
} else {
emptyView.setVisibility(View.VISIBLE);
emptyView.setText(getString(R.string.No_New_Orders));
}
swiperefresh.setRefreshing(false);
}
});
return rootView;
}
}
I figured it out, I just added these two lines after I make the request..!
orders.remove(position);
notifyItemRemoved(position);
//notifyDataSetChanged(position);

I think you are almost there. (assuming pecLue is your little eye image)
Pseudo code:
holder.pecLue.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//if(holder.pecLue.getVisibility()== View.VISIBLE)
// holder.pecLue.setVisibility(View.INVISIBLE);
if(conditionIfChapterIsMarked){
holder.pecLue.setImageResource(R.drawable.pec_lue_icon_unmarked);
//unmarkChapterLogic()
}else{
holder.pecLue.setImageResource(R.drawable.pec_lue_icon_marked);
//markChapterLogic()
}
}
});
