Unable to dismiss progress dialog

Question

Here is my code segment I am trying to dismiss dialog but it is not getting dismissed and also i don't get any error on logcat.Please correct me where i am wrong ?

All the Log.v statement get executed.Even log.v statement after pd.dismiss() (Log.v("TAG","progress dismiss");) gets printed.

Please point my mistake or suggest some alternative way to dismiss the progressdialog.

 btnSave.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View arg0) {

                        // TODO Auto-generated method stub
                        //do something
                        } else {
                            Log.v("TAG","above progressDialog");
                            final ProgressDialog pd = new ProgressDialog(ChangePassword.this);
                            ProgressDialog.show(ChangePassword.this, "", "Loading...", false, true);
                            new Thread() {

                                        sleep(2000);
                                        Log.v("TAG","in try block");

You are not dismissing the same ProgressDialog that you are showing. Replace this:

final ProgressDialog pd = new ProgressDialog(ChangePassword.this);
ProgressDialog.show(ChangePassword.this, "", "Loading...", false, true);

with this:

final ProgressDialog pd = ProgressDialog.show(ChangePassword.this, "", "Loading...", false, true);
