Android AsyncTask Progress bar [duplicate]

Answer 1

Please try this

public class LoadData extends AsyncTask<Void, Void, Void> {
    ProgressDialog progressDialog;
    //declare other objects as per your need
    @Override
    protected void onPreExecute()
    {
        progressDialog= ProgressDialog.show(YourActivity.this, "Progress Dialog Title Text","Process Description Text", true);

        //do initialization of required objects objects here                
    };      
    @Override
    protected Void doInBackground(Void... params)
    {   

         //do loading operation here  
        return null;
    }       
    @Override
    protected void onPostExecute(Void result)
    {
        super.onPostExecute(result);
        progressDialog.dismiss();
    };
 }

You can call this using

LoadData task = new LoadData();
task.execute();
