I've tried storing the uri to a different class which was successful but I had to make another list for myAdapter which added more problems to the table.
MyAdapter.java
package com.example.byete_hunger_mobileapp;
import android.content.Context;
import android.content.Intent;
import android.transition.AutoTransition;
import android.transition.TransitionManager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.cardview.widget.CardView;
import androidx.recyclerview.widget.RecyclerView;
import com.bumptech.glide.Glide;
import java.util.ArrayList;
import java.util.List;
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
Context context;
ArrayList<donation> list;
public MyAdapter(Context context, ArrayList<donation> list) {
this.context = context;
this.list = list;
}
@NonNull
@Override
public MyAdapter.MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(context).inflate(R.layout.donation_card, parent, false);
return new MyAdapter.MyViewHolder(v);
}
@Override
public void onBindViewHolder(@NonNull MyAdapter.MyViewHolder holder, int position) {
donation Donation = list.get(position);
holder.type.setText(Donation.getType());
holder.weight.setText(Donation.getWeight());
holder.datePurchased.setText(Donation.getDatePurchased());
holder.dateExpired.setText(Donation.getDateExpired());
holder.notes.setText(Donation.getNotes());
holder.id.setText(Donation.getId());
holder.dateAdded.setText(Donation.getDateAdded());
holder.dateAddedTime.setText(Donation.getDateAddedTime());
Glide.with(context).load(Donation.getImageUrl()).into(holder.donationCardImage);
}
@Override
public int getItemCount() {
return list.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder {
TextView type, weight, datePurchased, dateExpired, notes, id, dateAdded, dateAddedTime;
Button track;
CardView cardView;
ImageView donationCardImage;
RelativeLayout donationcardcontent;
public MyViewHolder(@NonNull View itemView) {
super(itemView);
type = itemView.findViewById(R.id.tv_donationcard_typedesc);
weight = itemView.findViewById(R.id.tv_donationcard_weightdesc);
datePurchased = itemView.findViewById(R.id.tv_donationcard_dateofpurchasedesc);
dateExpired = itemView.findViewById(R.id.tv_donationcard_expirationdatedesc);
notes = itemView.findViewById(R.id.tv_donationcard_notesdesc);
id = itemView.findViewById(R.id.tv_donationcard_uidCode);
dateAdded = itemView.findViewById(R.id.tv_donationcard_dateadded);
dateAddedTime = itemView.findViewById(R.id.tv_donationcard_dateaddedTime);
donationCardImage = itemView.findViewById(R.id.iV_donationcard);
track = itemView.findViewById(R.id.btn_donationcard_track);
cardView = itemView.findViewById(R.id.cv_donationCard);
donationcardcontent = itemView.findViewById(R.id.rl_donationcard_content);
track.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(cardView.getContext(),statustracker.class);
cardView.getContext().startActivity(intent);
}
});
// donation card expands and collapses
cardView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (donationcardcontent.getVisibility() == View.GONE) {
TransitionManager.beginDelayedTransition(cardView, new AutoTransition());
donationcardcontent.setVisibility(View.VISIBLE);
} else if (donationcardcontent.getVisibility() != View.GONE) {
TransitionManager.beginDelayedTransition(cardView, new AutoTransition());
donationcardcontent.setVisibility(View.GONE);
}
}
});
}
}
}
So I want to know if there's a possible work around for storing the uri to my donation class.
CodePudding user response：
The line
donation image = new donation(uri.toString());
will create a new donation from String. Probably this is not what is wanted. If the goal is to set imageUrl after the image is uploaded, then replace this line with:
Donation.setImageUrl(uri.toString());
And in donation.java, add setter for imageUrl:
public void setImageUrl(String url) {
this.imageUrl = url;
}
