Java – how to use onclicklistener in the recycle bin view?

See English answer > recyclerview onclick34

package com.albumlist.albumlist;

import android.content.Context;
import android.content.Intent;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private AlbumData[] itemsData;

    public MyAdapter(AlbumData[] itemsData){
        this.itemsData = itemsData;
    }

    public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

        private TextView txtViewTitle;
        private ImageView imgViewIcon;

        public ViewHolder(View itemLayoutView) {
            super(itemLayoutView);
            itemLayoutView.setOnClickListener(this);
            txtViewTitle = (TextView) itemLayoutView.findViewById(R.id.album_title);
            imgViewIcon = (ImageView) itemLayoutView.findViewById(R.id.album_icon);
        }

        @Override
        public void onClick(View v) {

        }
    }

    @Override
    public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {

        View itemLayoutView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.data_layout,null);

        ViewHolder viewHolder = new ViewHolder(itemLayoutView);
        return viewHolder;
    }

    @Override
    public void onBindViewHolder(ViewHolder viewHolder,int position) {

        viewHolder.txtViewTitle.setText(itemsData[position].getTitle());
        viewHolder.imgViewIcon.setImageResource(itemsData[position].getImageUrl());
    }

    @Override
    public int getItemCount() {
        return itemsData.length;
    }

}

Solution

This concept is well summarized in Xaver Kapeller's comments If you are looking for a simple way to manage the recyclerview interaction, just like the traditional interaction of listview, please check the bignerdranch's recyclerview multiselect library on GitHub They have a sample application that can be explored, which implements a series of onclicklisteners and onlongclicklisteners with multiple selection

The following is the code snippet of how bignerdranch implements the listener in the fragment through the adapter and viewholder. In this case, it is actually an extension of the swapingholder of the library itself

public CrimeHolder(View itemView) {
        super(itemView,mMultiSelector);

        mTitleTextView = (TextView) itemView.findViewById(R.id.crime_list_item_titleTextView);
        mDateTextView = (TextView) itemView.findViewById(R.id.crime_list_item_dateTextView);
        mSolvedCheck@R_925_2419@ = (Check@R_925_2419@) itemView.findViewById(R.id.crime_list_item_solvedCheck@R_925_2419@);
        itemView.setOnClickListener(this);
        itemView.setLongClickable(true);
        itemView.setOnLongClickListener(this);
    }

    public void bindCrime(Crime crime) {
        mCrime = crime;
        mTitleTextView.setText(crime.getTitle());
        mDateTextView.setText(crime.getDate().toString());
        mSolvedCheck@R_925_2419@.setChecked(crime.isSolved());
    }

    @Override
    public void onClick(View v) {

        if (mCrime == null) {
            return;
        }
        if (!mMultiSelector.tapSelection(this)) {
            selectCrime(mCrime);
        }

    }


    @Override
    public boolean onLongClick(View v) {

        ((AppCompatActivity) getActivity()).startSupportActionMode(mDeleteMode);
        mMultiSelector.setSelected(this,true);
        return true;
    }


}


private class CrimeAdapter extends RecyclerView.Adapter<CrimeHolder> {
    @Override
    public CrimeHolder onCreateViewHolder(ViewGroup parent,int pos) {
        View view = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.list_item_crime,parent,false);
        return new CrimeHolder(view);
    }

    @Override
    public void onBindViewHolder(CrimeHolder holder,int pos) {
        Crime crime = mCrimes.get(pos);
        holder.bindCrime(crime);
        Log.d(TAG,"binding crime" + crime + "at position" + pos);
    }

    @Override
    public int getItemCount() {
        return mCrimes.size();
    }
}
