使用Segi和android_beginner的答案（非常感谢您），我发布了我的问题的解决方案：

Using the answers of Segi and android_beginner (thank you very much) I'm posting the solution of my problem:

        pDialog = new ProgressDialog(mContext);
        pDialog.setTitle(Reso.getString(mContext, R.string.waiting));
        pDialog.setMessage(Reso.getString(mContext, R.string.waiting));
        pDialog.setIndeterminate(true);
        pDialog.setCancelable(false);
        pDialog.setButton(DialogInterface.BUTTON_NEGATIVE,
                Reso.getString(mContext, R.string.annulla),
                new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // Stuff
            }
        });
        pDialog.show();
        pDialog.getButton(DialogInterface.BUTTON_NEGATIVE).setVisibility(View.INVISIBLE);

        int progressDialogCancelButtonDelay = 2500;

        new CountDownTimer(progressDialogCancelButtonDelay, progressDialogCancelButtonDelay + 1) {

            @Override public void onTick(long millisUntilFinished) { }

            @Override public void onFinish() {
                pDialog.getButton(ProgressDialog.BUTTON_NEGATIVE).setVisibility(View.VISIBLE);
            }
        }.start();

推荐答案

尝试以下代码：

 ProgressDialog loadingDialog = ProgressDialog.show(activity.this, "", "Loading...",
                true, false);

        new Thread(new Runnable() {

            @Override
            public void run() {
                try {

                    Thread.sleep(2500);
                    runOnUiThread(new Runnable() {
                        public void run() {



                                loadingDialog.dismiss();

                               loadingDialog.setButton(ProgressDialog.BUTTON_NEUTRAL,
                                                 "Close",
                               new DialogInterface.OnClickListener()                 {
                              @Override
                               public void onClick(DialogInterface dialog, int which) {
                            //button click stuff here
                          }
                     });

                    loadingDialog.show();
                   loadingDialog.getButton(ProgressDialog.BUTTON_NEUTRAL).setVisibility(View.INVISIBLE);

                            }
                        }
                    });
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

            }
        }).start();
