Below is my fragment class from which I want to fetch values, but it is giving me error.
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_register_company, container, false);
bindViews();
return rootView;
}
private void bindViews() {
companyName = rootView.findViewById(R.id.companyName);
compAddress1 = rootView.findViewById(R.id.compAddress1);
compAddress2 = rootView.findViewById(R.id.compAddress2);
compCountry = rootView.findViewById(R.id.compCountry);
compState = rootView.findViewById(R.id.compState);
compCity = rootView.findViewById(R.id.compCity);
compWebsite = rootView.findViewById(R.id.compWebsite);
compEmail = rootView.findViewById(R.id.compEmail);
compPhone = rootView.findViewById(R.id.compPhone);
}
public HashMap<String, String> getCompanyDetails() {
companyNameString = companyName.getText().toString();
compAddress1String = compAddress1.getText().toString();
compAddress2String = compAddress2.getText().toString();
compCountryString = compCountry.getText().toString();
compStateString = compState.getText().toString();
compCityString = compCity.getText().toString();
compWebsiteString = compWebsite.getText().toString();
compEmailString = compEmail.getText().toString();
compPhoneString = compPhone.getText().toString();
HashMap<String, String> map = new HashMap<>();
map.put("companyNameString", companyNameString);
map.put("compAddress1String", compAddress1String);
map.put("compAddress2String", compAddress2String);
map.put("compCountryString", compCountryString);
map.put("compStateString", compStateString);
map.put("compCityString", compCityString);
map.put("compWebsiteString", compWebsiteString);
map.put("compEmailString", compEmailString);
map.put("compPhoneString", compPhoneString);
return map;
}
This is my function inside my Main Activity from which I am trying to fetch values.
private void collectData() {
HashMap<String, String> compMap= new RegisterCompanyFragment().getCompanyDetails();
companyNameString = compMap.get("companyNameString");
compAddress1String = compMap.get("compAddress1String");
compAddress2String = compMap.get("compAddress2String");
compCountryString = compMap.get("compCountryString");
compStateString = compMap.get("compStateString");
compCityString = compMap.get("compCityString");
compWebsiteString = compMap.get("compWebsiteString");
compEmailString = compMap.get("compEmailString");
compPhoneString = compMap.get("compPhoneString");
}
Here is the error, I guess this error is because the edit-text has not bind to the view and still I am trying to use it. So kindly help me to resolve this by providing a method to access the values of edit text from the fragment. For more information kindly comment below. Thank You.
