How to control elements within an item in an android listview?

You must set the listener on the adapter and call it to retrieve the events through an interface, then a code snippet of an application of mine, the logic is the same

GalleryAdapter

In the case of ListView you should create a custom adapter with the BaseAdapter , but in my case I I use the RecyclerView adapter:

package com.samuelives.videoplayer.util;

import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.TextView;

import com.bumptech.glide.Glide;
import com.bumptech.glide.request.RequestOptions;
import com.samuelives.videoplayer.R;

import java.util.ArrayList;

public class GalleryAdapter extends RecyclerView.Adapter<GalleryAdapter.GalleryHolder> {

    private ArrayList<GalleryItem>mItems;
    private Context mContext;
    private LayoutInflater mInflater;
    private RequestOptions mThumbOptions;
    private GalleryListener mGalleryListener;

    public GalleryAdapter(@NonNull Context context, ArrayList<GalleryItem>items){
        mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        int optionW = (int)(context.getResources().getDimension(R.dimen.rowVideoThumbnailW) / context.getResources().getDisplayMetrics().density);
        int optionH = (int)(context.getResources().getDimension(R.dimen.rowVideoThumbnailH) / context.getResources().getDisplayMetrics().density);
        this.mThumbOptions = new RequestOptions().override(optionW, optionH).centerCrop();
        this.mContext = context;
        this.mItems = items;
    }

    public ArrayList<GalleryItem> getData(){
        return mItems;
    }

    public void addItem(GalleryItem item, int position){
        mItems.add(item);
        notifyItemInserted(position);
        notifyItemRangeChanged(position, mItems.size());
    }

    public void removeItem(int position){
        mItems.remove(position);
        mItems.trimToSize();
        notifyItemRemoved(position);
        notifyItemRangeChanged(position, mItems.size());
    }

    public void setGalleryListener(GalleryListener listener){
        this.mGalleryListener = listener;
    }

    @NonNull
    @Override
    public GalleryHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v = mInflater.inflate(R.layout.gallery_list, parent, false);
        return new GalleryHolder(v);
    }

    @Override
    public void onBindViewHolder(@NonNull GalleryHolder holder, int position) {

        GalleryItem item = mItems.get(position);

        holder.title.setText(item.getVideoTitle());
        Glide.with(mContext).load(item.getVideoFile()).apply(mThumbOptions).into(holder.thumbnail);
    }

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

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

        ImageView thumbnail = null;
        TextView title = null;
        private ImageButton popupButton;

        public GalleryHolder(View itemView) {
            super(itemView);

            thumbnail = (ImageView)itemView.findViewById(R.id.rowVideoThumbnail);
            title = (TextView)itemView.findViewById(R.id.rowVideoTitle);
            popupButton = (ImageButton) itemView.findViewById(R.id.rowBtnPopup);
            popupButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    mGalleryListener.onItemContextClick(popupButton, getAdapterPosition());
                }
            });

            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View v) {
            mGalleryListener.onItemClick(v, getAdapterPosition());
        }
    }

    public interface GalleryListener{

        void onItemClick(View v, int position);

        //Nesta linha eu defino um listener para cada botão de cada item do meu recycler view, no se caso você deve criar uma inteface para os listener da sua SeekBar
        void onItemContextClick(ImageButton btn, int position);

    }
}

GalleryFragment

This fragment that has the list in question, here I treat all listeners

public class GalleryFragment extends Fragment {

    private RecyclerView rvGallery = null;

    private ArrayList<File> mVideos = null;

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        //Setup RecycleView
        rvGallery.setHasFixedSize(true);

        LinearLayoutManager llManager = new LinearLayoutManager(getActivity());
        llManager.setOrientation(LinearLayoutManager.VERTICAL);

        rvGallery.setLayoutManager(llManager);

        File storageLocation = null;

        try{

            if(prefs.getBoolean("pref_key_is_storage_in_sdcard", true)){
                storageLocation = StorageHelper.getStorage(getActivity());
                if(!storageLocation.exists()){
