Question

I am trying to create downloading progress. I have my class which extends AsyncTask:
public class DownloadFileTask extends AsyncTask

When downloading starts i want to create progress:

  @Override
  protected void onPreExecute() {



   progressDialog = new ProgressDialog(whatContext);
   progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
   progressDialog.setMessage("Loading...");
   progressDialog.setCancelable(false);
   progressDialog.show();
  }

But i don’t know what context i should give to new ProgressDialog becouse i am not in Activity class. I tried to give some context but there an error:

No enclosing instance of the type Main_Tab is accessible in
scope

So how i could create this progress ?

Also i wanted to create progress not in this class (becouse i want seperate functions and design), but i did’t figure out how to do that.

Thank you guys for help.

Answer 1

 public class DownloadFileTask extends AsyncTask{
Context mContext;

    public DownloadFileTask(Context context) {
            this.mContext = context;

        }


     @Override
      protected void onPreExecute() {



       progressDialog = new ProgressDialog(mContext);
       progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
       progressDialog.setMessage("Loading...");
       progressDialog.setCancelable(false);
       progressDialog.show();
      }
    }

To start DownloadTask call like

 DownloadFileTask task = new DownloadFileTask(MyActivity.This);
 task.execute();
