android - Difficulties with dispalying progressdialog -

I need to display a progress sign. It is quite simple, though I must wait completely unless Aynccutcus will not be finished. This boycotts some difficulties for me Asynctask method is used to wait for .get () to complete. But this method block my progress dialog, how can I get the progress_dialog or change the .get () Am I

I am calling the operation as follows:

  operation o = new operation (); O.execute (parameter); Try {o.get (); } Grip (Interrupted E) E. {// TODO Auto-Generated Catch Block e.printStackTrace (); } Hold (execution exception e) {// TODO auto generated blocking block e.printStackTrace (); }   
 class operation  
  class operation AsyncTask and lt; String, zero, JSONObject & gt; {Progress DIOLOG PD; Context associated; Prerequirer protected override @ (zero); new progressivity (AP); Pd.setOwnerActivity (app); Pd.setTitle ("Ð ?? Ð'ÐμÑ ?? Ð · Ð ° Ð³Ñ ?? Ñ ?? Ð · кР° ..."); Pd.setCancelable (true); Pd.show (); } @ Override protected JSONObject doInBackground (string ... option) {/ * some jobs * / return Jason; } @Override Secure Zero PostExecute (JSONObject Results) {super.onPostExecute (Results); Pd.dismiss (); / * Some jobs * /}}    
 
 
 Do not use . ()  As you have seen, it blocks  UI . You can use  getStatus ()  if you want to check whether the job is finished or not. Deleting  .get ()  should allow you to show the  ProgressDialog . If you have a code that will have to wait until the  AsyncTask  is finished, call it at PostExecute ()  at  or a function in  
 if You need to refer to something in  main activity  asyncTask  after completion of it, just create a constructor to get a reference of your  activity  And pass  context  your  manufacturer   
  operation o = new operation (this);   
 and refer to it in the constructor  
  lass operation AsyncTask & lt; String, zero, JSONObject & gt; {Progress DIOLOG PD; Context associated; Activity act; Public operator (activity action) {act = curact; // This reference can be used to access methods in your activity}
