Android几秒后自动关闭dialog

AlertDialog.Builder builder = new AlertDialog.Builder(v.getContext());

                builder.setTitle("发送成功！");

                builder.setMessage("2秒后自动关闭！");

                builder.setCancelable(true);

                final AlertDialog dlg = builder.create();

                dlg.show();

                final Timer t = new Timer();

                t.schedule(new TimerTask() {

                    public void run() {

                        Intent intent1 = new Intent();

                        intent1.setClass(InquirySheetListActivity.this, MainActivity.class);

                        startActivity(intent1);

                        finish();

                        dlg.dismiss();

                        t.cancel();

                    }
