我的HomeFragment上的EditText出现问题。我正在尝试在4个EditTexts（firstDigits，secondDigits，thirdDigits和fourthDigits）上输入IP地址，并将其显示在我的TextView（服务器）上。我的问题是，它不是在保存。 我还想让它显示在其他片段上。任何人？ ：（
public class HomeFragment extends Fragment implements View.OnClickListener {
TextView loggedName, loggedEmail, server;
UserLocalStore userLocalStore;
Button bConnect, bClear;
EditText firstDigits, secondDigits, thirdDigits, fourthDigits;

View v;
// Required empty public constructor
}

public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
