Question

例如，我想添加此否定按钮，但是3秒后。

是否可以，或者我必须关闭此progressDialog并打开一个新对话框？

我尝试过：

final ProgressDialog progressDialog = new ProgressDialog(this,
            R.style.Theme_AppCompat_DayNight_Dialog);
    progressDialog.setIndeterminate(true);
    progressDialog.setCancelable(false);
    progressDialog.setMessage("Bla bla bla ...");

    progressDialog.show();

    progressDialog.setButton(DialogInterface.BUTTON_NEGATIVE,"NO", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            progressDialog.dismiss();
        }
    });

    SystemClock.sleep(3000);

    progressDialog.show();

将按钮保持隐藏状态，并在打开对话框后使用此代码
