Download Manager to be adapted to recyclerview
I went through almost all what is available on internet about downloading a file from internet and one of the tutorials worked
In that tutorial they've used download manager but it was for a button ..i'm using a recyclerview with items having a single dwonload button and each download button of the items list has a different url , please show me how to do that!
what i've tried:( i know it's not the right syntax for personViewHolder.personbutton.setOnClickListener but just to show you what i kinda want)
Photo from the emulator of my app!
RVadapter.java
public class RVAdapter extends RecyclerView.Adapter<RVAdapter.PersonViewHolder> {
public static class PersonViewHolder extends RecyclerView.ViewHolder {
CardView cv;
TextView personName;
TextView personAge;
ImageView personPhoto;
Button personbutton;
PersonViewHolder(View itemView) {
super(itemView);
cv = (CardView)itemView.findViewById(R.id.cv);
personName = (TextView)itemView.findViewById(R.id.person_name);
personAge = (TextView)itemView.findViewById(R.id.person_age);
personPhoto = (ImageView)itemView.findViewById(R.id.person_photo);
personbutton=(Button)itemView.findViewById(R.id.imgbuttondownload);
}
}
List<Person> persons;
RVAdapter(List<Person> persons){
this.persons = persons;
}
@Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
@Override
public PersonViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item, viewGroup, false);
PersonViewHolder pvh = new PersonViewHolder(v);
return pvh;
}
@Override
public void onBindViewHolder(PersonViewHolder personViewHolder, final int i) {
personViewHolder.personName.setText(persons.get(i).name);
personViewHolder.personAge.setText(persons.get(i).age);
personViewHolder.personPhoto.setImageResource(persons.get(i).photoId);
personViewHolder.personPhoto.setOnClickListener(new View.OnClickListener(){

Solution
you can simply hold your URL in Person object and then whenever a click happens just retrieve it and send it to download manager. it will be something like this:
personViewHolder.personbutton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Person person = persons.get(i);
String url = person.url;
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setDescription(person.name);
request.setTitle(person.description);
request.allowScanningByMediaScanner();
request.setNotificationVisibility(
DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "file"+person.name+".mp4");
manager.enqueue(request);
}});
