recyclerView touch listener using a button

   recyclerView.addOnItemTouchListener(new GalleryAdapter.RecyclerTouchListener(this, recyclerView, new GalleryAdapter.ClickListener()
        {

            @Override
            public void onClick(View view, int position) {
                //Values are passing to activity & to fragment as well

                int id = view.getId();


                    if(id == R.id.carasoul_button) {
                        Intent intent = new Intent(mainActivityCarasoul.this, PDFViewerActivity.class);
                        intent.putExtra(PDFViewerActivity.TAG, books.get(position));
                        intent.putExtra("from", "mo2lfatActivity");
                        startActivity(intent);
                    }



            }

            @Override
            public void onLongClick(View view, int position) {

            }
        }));

what this code does is when i click on the item in recycle view another activity will be opened, i wanna change that with a button that can be pressed that will open the activity.

I tried the above code and it didn't work. i put the button outside the RecycleView

The button is not in this xml layout.gallery_thumbnail.If i put it here it will be in all the views. The button is in the main xml which has recycle view itself.

@Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.gallery_thumbnail, parent, false);

        return new MyViewHolder(itemView);
    }

This is working code. I have tested it. You have to define your button click inside adapter. And it will work like charm. Let me know if you face any issue.

If you want to position of your item then just add a tag of that view in your onBindViewHolder method. Here is the code example:

@Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
     holder.yourButton.setTag(position);
}

In your ViewHolder Constructor method, add onClickListener on your button. here is sample:

    public MyViewHolder(View view) {
                    super(view);
        Button yourButton = (Button) view.findViewById(R.id.YOUR_BUTTON_ID);

        yourButton.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {

  Button button = (Button) v.findViewById(R.id.YOUR_BUTTON_ID);
        Intent intent = new Intent(context, PDFViewerActivity.class);
                intent.putExtra(PDFViewerActivity.TAG, ""+button.getTag());
                intent.putExtra("from","mo2lfatActivity");
                context.startActivity(intent);
        }
    }

Here, context is the activity context, that can you pass by Adapter Constructor.

Thanks :)

In your ViewHolder class you can set OnClickListener for that button and override onClick() method to open another activity.

class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    public Button btMyButton;

    public ViewHolder(View itemView) {
        super(itemView);
        btMyButton = (Button) itemView.findViewById(R.id.bt_my_button);
        btMyButton.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if (v.getId() == R.id.bt_my_button){
           Intent intent = new Intent(v.getContext(), PDFViewerActivity.class);
           intent.putExtra(PDFViewerActivity.TAG, books.get(getAdapterPosition()));
           intent.putExtra("from","mo2lfatActivity");
           startActivity(intent);               
        }
    }
 }

First, add implementation to your activity:

public class Main extends ActionBarActivity implements View.OnClickListener {
   // do your stuff
}

This:

buttonname.setOnClickListener(this);

means that you want to assign listener for your Button "on this instance" -> this instance represents OnClickListener and for this reason your class have to implement that interface.

It's similar with anonymous listener class (that you can also use):

buttonname.setOnClickListener(new View.OnClickListener() {

   public void onClick(View view) {
        recyclerView.addOnItemTouchListener(new GalleryAdapter.RecyclerTouchListener(this, recyclerView, new GalleryAdapter.ClickListener() {
        @Override
        public void onClick(View view, int position) {
            // Values are passing to activity & to fragment as well
            // Toast.makeText(mainActivityCarasoul.this, "Single Click on position: "+position,
            // Toast.LENGTH_SHORT).show();
            Intent intent = new Intent(mainActivityCarasoul.this, PDFViewerActivity.class);
            intent.putExtra(PDFViewerActivity.TAG, books.get(position));
            intent.putExtra("from","mo2lfatActivity");
            startActivity(intent);
        }

        @Override
        public void onLongClick(View view, int position) {

        }
    }));
   }
});

@Override
public void onBindViewHolder(ItemViewHolder itemViewHolder, int i) {
    itemViewHolder.button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //Intent Code
        }
    });
}

This will work..
