How to dismiss PopupWindow containing recyclerview by clicking an item in the recyclerview

I have a PopupWindow which contains a RecyclerView filled with items. I want to dismiss the PopupWindow after selecting an item in the recycleview.
I know it has to be implemented with a interface, but not quite sure on how to do it in the code. Right now the items are displaying in the popupwindow and I could get the items printed in toast. It will be helpful if anybody could look to my code and guide me.

Why adnroidx recycler-view click not working when click it's item?

I'm trying to implement RecyclerView onclick listener, but it is not working. I've tried a lot, and try to implement other way too, but not working at all.
My Main Class:
public class MainMenuDashboard extends AppCompatActivity{
private RecyclerView recyclerMenu;
private RecyclerViewMenuAdapter menuAdapter;
private Call<CategoryModel> categoryModelCall;
private TokenManager tokenManagerMainMenu;
private ApiService serviceMainMenu;
List<CategoryModel.Subset> menuList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_menu_dashboard);
tokenManagerMainMenu = TokenManager.getInstance(getSharedPreferences("prefs", MODE_PRIVATE));
serviceMainMenu = RetrofitBuilder.createServiceWithAuth(ApiService.class, tokenManagerMainMenu);
recyclerMenu = findViewById(R.id.recyclerMenu);
menuList = new ArrayList<>();
GridLayoutManager layoutManager = new GridLayoutManager(MainMenuDashboard.this, 2, GridLayoutManager.VERTICAL, false);
recyclerMenu.setLayoutManager(layoutManager);
menuAdapter = new RecyclerViewMenuAdapter(menuList);
recyclerMenu.setAdapter(menuAdapter);
menuAdapter.notifyDataSetChanged();
mainMenuDashBoardToolbar = findViewById(R.id.mainMenuDashBoardToolbar);
setSupportActionBar(mainMenuDashBoardToolbar);
menuContent();
}
private void menuContent() {
categoryModelCall = serviceMainMenu.menuContent(incomingRoleId, true);
categoryModelCall.enqueue(new Callback<CategoryModel>() {
#Override
public void onResponse(#NotNull Call<CategoryModel> call, #NotNull Response<CategoryModel> response) {
if (response.isSuccessful() && response.body() != null && response.code() != 400) {
//findViewById(R.id.shimmerCategory).setVisibility(View.GONE);
CategoryModel categoryModel = response.body();
menuList = categoryModel.getSubset();
menuAdapter = new RecyclerViewMenuAdapter(menuList);
recyclerMenu.setAdapter(menuAdapter);
//menuAdapter.notifyDataSetChanged();
menuAdapter.setOnItemClickListener(new RecyclerViewMenuAdapter.ClickListenerMenu() {
#Override
public void onClick(int position) {
Toast.makeText(MainMenuDashboard.this, "Position "+position+" Clicked", Toast.LENGTH_SHORT).show();
menuAdapter.notifyDataSetChanged();
}
});
menuAdapter.notifyDataSetChanged();
}else {
if (response.code() == 401) {
Intent i = new Intent(MainMenuDashboard.this, MainActivity.class);
i.putExtra("USER_SESSION", true);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
tokenManagerMainMenu.deleteToken();
startActivity(i);
finish();
}
}
}
#Override
public void onFailure(#NotNull Call<CategoryModel> call, #NotNull Throwable t) {
}
});
}
}
My Adapter:
public class RecyclerViewMenuAdapter extends RecyclerView.Adapter<RecyclerViewMenuAdapter.RecyclerViewHolder> {
private static final String TAG = "NotesRecyclerAdapter";
private List<CategoryModel.Subset> subsetsCategories;
private ClickListenerMenu mClickListener;
private Context context;
public RecyclerViewMenuAdapter(List<CategoryModel.Subset> subsetsCategories) {
this.subsetsCategories = subsetsCategories;
}
#NonNull
#Override
public RecyclerViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_recycler_main_menu_category, parent, false);
return new RecyclerViewHolder(view, mClickListener);
}
#Override
public void onBindViewHolder(#NonNull final RecyclerViewHolder viewHolder, final int position) {
String menuCategoryImage = subsetsCategories.get(position).getIcon();
Picasso.get().load(menuCategoryImage).placeholder(R.drawable.admin).into(viewHolder.menuThumb);
String menuCategoryName = subsetsCategories.get(position).getName();
viewHolder.menuName.setText(menuCategoryName);
//Item click
viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view)
{
mClickListener.onClick(position);
//Toast.makeText(context, "Position "+position+" Clicked", Toast.LENGTH_SHORT).show();
notifyDataSetChanged();
}
});
}
#Override
public int getItemCount() {
return subsetsCategories.size();
}
public static class RecyclerViewHolder extends RecyclerView.ViewHolder{
ImageView menuThumb;
TextView menuName;
private ClickListenerMenu mListener;
//ClickListenerMenu clickListenerMenu;
public RecyclerViewHolder(View view, ClickListenerMenu clickListenerMenu) {
super(view);
menuThumb = view.findViewById(R.id.menuThumb);
menuName = view.findViewById(R.id.menuName);
mListener = clickListenerMenu;
}
}
public void setOnItemClickListener(ClickListenerMenu clickListener) {
mClickListener = clickListener;
}
public interface ClickListenerMenu {
void onClick(int position);
}
}
I still can't find where I did wrong!! Any insight will be very appreciated
Thank You

Add item click listener in your adapter.
#Override
public void onBindViewHolder(#NonNull RecyclerViewHolder viewHolder, int position) {
String menuCategoryImage = subsetsCategories.get(position).getIcon();
Picasso.get().load(menuCategoryImage).placeholder(R.drawable.admin).into(viewHolder.menuThumb);
String menuCategoryName = subsetsCategories.get(position).getName();
viewHolder.menuName.setText(menuCategoryName);
//Item click
viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view)
{
// Do something
}
});
}
Initialise your recycler view outside and put this line menuAdapter.notifyDataSetChanged(); where you add data in your list.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_menu_dashboard);
tokenManagerMainMenu = TokenManager.getInstance(getSharedPreferences("prefs", MODE_PRIVATE));
serviceMainMenu = RetrofitBuilder.createServiceWithAuth(ApiService.class, tokenManagerMainMenu);
recyclerMenu = findViewById(R.id.recyclerMenu);
menuList = new List<CategoryModel.Subset>();
GridLayoutManager layoutManager = new GridLayoutManager(MainMenuDashboard.this, 2, GridLayoutManager.VERTICAL, false);
recyclerMenu.setLayoutManager(layoutManager);
menuAdapter = new RecyclerViewMenuAdapter(menuList);
recyclerMenu.setAdapter(menuAdapter);
menuAdapter.notifyDataSetChanged();
menuContent();
}
I hope this can help you!

Add these line in the onBindViewHolder() method:
viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//remove this lines
//mClickListener.onClick(position);
//notifyDataSetChanged();
//add this
context.startActivity(new Intent(context,SecondActivity.class))
}
});
and in your MainMenuDashboard class, initialize your Adapter like this:
menuAdapter = new RecyclerViewMenuAdapter(this,menuList);
also change your Adapter constructor like this:
public RecyclerViewMenuAdapter(Context context,List<CategoryModel.Subset> subsetsCategories) {
this.subsetsCategories = subsetsCategories;
this.context = context;
}
```

android - recyclerview cannot click and get position

I have tried some code to can click recyclerview item and get position, but I can't click the recyclerview item.. the data I get from url. So I wan't switch activity with get the item user click..
how I can fix that?
this code for adapter
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {
Context context;
private static final String TAG = RecyclerViewAdapter.class.getSimpleName();
List<GetDataAdapter> getDataAdapter;
ImageLoader imageLoader1;
public RecyclerViewAdapter(List<GetDataAdapter> getDataAdapter, Context context) {
super();
this.getDataAdapter = getDataAdapter;
this.context = context;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.recyclerview_items, parent, false);
ViewHolder viewHolder = new ViewHolder(v);
return viewHolder;
}
#Override
public void onBindViewHolder(ViewHolder Viewholder, int position) {
GetDataAdapter getDataAdapter1 = getDataAdapter.get(position);
imageLoader1 = ServerImageParseAdapter.getInstance(context).getImageLoader();
imageLoader1.get(getDataAdapter1.getImageServerUrl(),
ImageLoader.getImageListener(
Viewholder.networkImageView,//Server Image
R.mipmap.ic_launcher,//Before loading server image the default showing image.
android.R.drawable.ic_dialog_alert //Error image if requested image dose not found on server.
)
);
Viewholder.networkImageView.setImageUrl(getDataAdapter1.getImageServerUrl(), imageLoader1);
Viewholder.ImageTitleNameView.setText(getDataAdapter1.getImageTitleName());
}
#Override
public int getItemCount() {
return getDataAdapter.size();
}
class ViewHolder extends RecyclerView.ViewHolder{
public TextView ImageTitleNameView;
public NetworkImageView networkImageView;
public ViewHolder(View itemView) {
super(itemView);
ImageTitleNameView = (TextView) itemView.findViewById(R.id.textView_item);
networkImageView = (NetworkImageView) itemView.findViewById(R.id.VollyNetworkImageView1);
}
}
}
and this code for mainactivity
public class MainActivity extends AppCompatActivity {
List<GetDataAdapter> GetDataAdapter1;
RecyclerView recyclerView;
RecyclerView.LayoutManager recyclerViewlayoutManager;
RecyclerView.Adapter recyclerViewadapter;
String GET_JSON_DATA_HTTP_URL = "http://androidblog.esy.es/ImageJsonData.php";

You need to set onClickListener to your item view. You can do by following below steps:
Set onCLickListener to root view of your list item.
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.recyclerview_items, parent, false);
Add below code in onCreateViewHolder:
v.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Add your logic here
}
});
You can add listener while onBindViewHolder:
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Add your logic here
}
});
Thanks.

Put a listener on your recycler item view and then in onclick, start intent to open new activity. Pass the data object you want to pass with the intent.
//make sure your model class GetDataAdapter implements Parcelable
holder.itemView.setOnclickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(this, ActivityToOpen.class);
intent.putExtra("key",Your Object to pass);// getDataAdapter1 in your case
context.startActivity(intent);
}
});
then in your Startted activity receive your object like this
YourObject obj = getIntent().getParcelableExtra("key");
//Your case
GetDataAdapter obj = getIntent().getParcelableExtra("key");

the fragment displays empty and no items appear even though i have added the data to arraylists and passed to the adapter. please help . thanks in advance

Problem is in below code you are returning 0 that's why its not showing any item
#Override
public int getItemCount() {
return 0;
}
You should return your list's size here either moviename.size(); or movieyear.size()

Android Recycler View

I am using RecyclerView to display my products, problem is when if I select the first products and scroll down to the end of list I see different products selected and when i scroll back to top of list the first item is not selected.

You have to take List(with boolean) and store selected values in that list and then use those values in onBindView()

In your ProductDetails class add a field boolean selected;
In your onClick() add List.get(position).setSelected(!List.get(position).isSelected()); to check/uncheck as needed.
Finaly in your onBindViewHolder(...) add
if(List.get(position).isSelected()){
holder.Imagelike.setVisibility(View.VISIBLE);
}else{
holder.ImageUnlike.setVisibility(View.GONE);
}
