I want edittext content to show on a recyclerview but it is not working this is the adapter

public class BookAdapter extends
RecyclerView.Adapter<BookAdapter.BookViewHolder>{
private LayoutInflater layoutInflater;
private EditText edittext1;
private Button button1;
public static ArrayList<Book> bookList;
public BookAdapter(Context context, String[] mDataset) {
layoutInflater = LayoutInflater.from(context);
bookList = new ArrayList<Book>(mDataset.length);
}
#Override
public BookViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.book_list_row, parent, false);
return new BookViewHolder(itemView);
}
#Override
public void onBindViewHolder(BookViewHolder holder, int position) {
holder. editText.setText(bookList.get(position).getEditTextValue());
Log.d("print","yes");
}
#Override
public int getItemCount() {
return bookList.size();
}
public class BookViewHolder extends RecyclerView.ViewHolder {
protected EditText editText;
public BookViewHolder(View itemView) {
super(itemView);
editText = (EditText) itemView.findViewById(R.id.edittext1);
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override

bookList.get(getAdapterPosition()).setEditTextValue(editText.getText().toString());
}
#Override
public void afterTextChanged(Editable editable) {
}
});
}
} }
and here is my main activity i use to get the code

}
I want the content to display onclick button but it is not working. I have tried different method but still the same thing. you can tell me where my error is and give me the correct to put there or edit the code I post and send me the correct one for easy correction.
You need to initialize your adapter before setting it to your recyclerview.
Something like
BookAdapter mAdapter = new BookAdapter(this, bookList);
before this line
recyclerView.setAdapter(mAdapter);
Also, you need to change your adapter implementation to receive an ArrayList<Book> instead of a String[] as a second argument
package c.androidchatapp.recyclerview.Adapter;
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.text.Editable;
import android.text.TextWatcher;
import android.util.Log;

import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import c.androidchatapp.recyclerview.Model.Book;
import c.androidchatapp.recyclerview.R;
import java.util.ArrayList;
import java.util.List;
public class BookAdapter extends RecyclerView.Adapter<BookAdapter.BookViewHolder>{
private LayoutInflater layoutInflater;
private EditText edittext1;
private Button button1;
public static ArrayList<Book> bookList;
public BookAdapter(Context context, ArrayList<Book> mDataset) {
layoutInflater = LayoutInflater.from(context);
bookList = new ArrayList<Book>(mDataset);
}
#Override
public BookViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.book_list_row, parent, false);
return new BookViewHolder(itemView);
}
#Override
public void onBindViewHolder(BookViewHolder holder, int position) {
holder. editText.setText(bookList.get(position).getEditTextValue());
Log.d("print","yes");
}
#Override
public int getItemCount() {
return bookList.size();
}
public class BookViewHolder extends RecyclerView.ViewHolder {
protected EditText editText;
public BookViewHolder(View itemView) {
super(itemView);
editText = (EditText) itemView.findViewById(R.id.edittext1);
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
bookList.get(getAdapterPosition()).setEditTextValue(editText.getText().toString());
}
#Override
public void afterTextChanged(Editable editable) {
}
});
}
} }
this is my new adapter code and this is the new mainactivity code too
package c.androidchatapp.recyclerview;

My RecyclerView gets the same value as the other once I edited/updated a specifc item. Here is the example of what I am getting instead of update one specific item only. example

}
#NonNull
#Override

}
#Override

I think the problem here is that I am setting my intent to my MainActivity.class and once I click edit/update on my MainActivity it also updates other items inside the RecyclerView, but still I don't know how to fix where and which is the problem here since I am just new and exploring things inside android studio.
I have an Android nested recycler view in which I am able to show the data now I want to show that data in another activity recycler view. How can I do that?
This is my nested list view:-

#Override
public void onBindViewHolder(#NonNull final HorizontalRVViewHolder holder, int position) {
final HorizontalModel horizontalModel = arrayList.get(position);
holder.textViewTitle.setText(horizontalModel.getVid_title());
com.bumptech.glide.Glide.with(context).load(horizontalModel.getVid_url()).into(holder.imageViewThumb);
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {

imageViewThumb = itemView.findViewById(R.id.ivThumb);

}
}
Data in list activity class (this is the activity where I need to show data):-
public class VideoListActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video_list);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setTitle(getIntent().getStringExtra("catTitle"));
}
}
Implement Parcelable on HorizontalModel class. If you need help with that check here.
In VerticalRVAdapter inside onBindViewHolder method
holder.buttonMore.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, verticalModel.getCat_title(), Toast.LENGTH_SHORT).show();
Intent i = new Intent(context, VideoListActivity.class);
i.putExtra("catTitle", verticalModel.getCat_title());
// Put horizontal models in extra bundle
i.putParcelableArrayListExtra("horizontal_models", singleItem);
context.startActivity(i);
}
});
You can now get the bundled HorizontalModel list in VideoListActivity inside onCreate as
ArrayList<HorizontalModel> horizontalModels = getIntent().getParcelableArrayListExtra("horizontal_models");
You can use this list to populate the vertical list that you want to show.
Suppose I have a scrolling RecyclerView (where images scrolling Horizontally) after clicking any of images it will appear below the recyclerView.

activity_main.xml : just have a recyclerView and image View
and images.xml : only a image view to set on RecyclerView
for get clicked item of recyckerview you have to use interface.
here is code sample:
first of all make one interface like below :
public interface ImageClickListener {
void onImageClick(String path);
}
now in your activity, make adapter's object like this
RecyclerViewAdapter adapter = new RecyclerViewAdapter(inputImages, this, new ImageClickListener() {
#Override
public void onImageClick(String path) {
Glide.with(context).load(path).into(imageView);
}
});
now create your adapter and make a constructor like this
public RecyclerViewAdapter(ArrayList<Integer> totalImages, Context context, ImageClickListener imageClickListener) {
this.totalImages = totalImages;
this.context = context;
this.imageClickListener = imageClickListener;
}
now you have an instance of interface in which you have one method, named onImageClick() in which you will pass the path of clicked image.
now on click of image do code like this:
viewHolder.singleImages.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
imageClickListener.onImageClick(totalImages.get(viewHolder.getAdapterPosition()));
}
});
now your method of interface will call & it will execute activity's image view to set the given path.
Enjoy codding :)

In on click get your worker id and put in extra , in the next activity put value event listner and get the respective data but you have one thing is that you have to have the id or something which can uniquely identify the reference of firebase.
holder.cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(mContext.getApplicationContext(),available_worker.class);
i.putExtra("uid",workerid);
mContext.startActivity(i);
}
});
in the next activity
String s = getIntent().getStringExtra("uid");
firebaseref.child(s).addvalueEventListner(////) {//pupulate your list view}
