Butterknife is working well when i am using it on Activities, but not working when I am trying to use it in a fragment :
public class SettingsFragment extends Fragment {
private static final String TAG = "SettingsFragment";
#BindView(R.id.settings_email) TextView _settingsMail;
#BindView(R.id.settings_password) TextView _passwordMail;
#BindView(R.id.settings_token) TextView _tokenMail;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
//returning our layout file
final View view = inflater.inflate(R.layout.fragment_3_settings, container, false);
ButterKnife.bind(this, view);
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this.getContext());
String email = prefs.getString("email", null);
String passwd = prefs.getString("password", null);
String token = prefs.getString("token", null);
_settingsMail.setText(email);
_passwordMail.setText(passwd);
_tokenMail.setText(token);
return inflater.inflate(R.layout.fragment_3_settings, container, false);
}
You have to return the view that you already have inflated, not inflate another view again.
Instead of:
return inflater.inflate(...);
Do this:
return view;
Try waiting until you know the view has been fully constructed before altering the layout.
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
//returning our layout file
final View view = inflater.inflate(R.layout.fragment_3_settings, container, false);
ButterKnife.bind(this, view);
return view;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this.getContext());
String email = prefs.getString("email", null);
String passwd = prefs.getString("password", null);
String token = prefs.getString("token", null);
_settingsMail.setText(email);
_passwordMail.setText(passwd);
_tokenMail.setText(token);
}
why nobody uses unbinder?
according to documentation , if you work with fragments, you have to use unbinder
private Unbinder unbinder;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate...;
unbinder = ButterKnife.bind(this, view);
return view;
}
and
#Override
public void onDestroyView() {
super.onDestroyView();
unbinder.unbind();
}
<ImageView
android:layout_marginTop="#dimen/padding_top_8dp
android:layout_centerHorizontal="true"
android:tint="#color/colorPrimary"
android:padding="#dimen/padding_top_8dp"
android:src="#drawable/ic_scan_qr_code"
android:id="#+id/qr__code_icon_iv"
android:background="#drawable/circle_shape_white"
android:layout_width="40dp"
android:layout_height="40dp" />
remove #id/qr__code_icon_iv
add #id/qr_code_icon_iv
This work for me:
...
#BindView(R.id.text_input)
TextView text_input;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_home, container, false);
ButterKnife.bind(this, view);
return view;
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
text_input.setText("Hello Lima, Perú");
...

So I haven't seen any question like this and I have a problem I don't know how to start the other class from the fragment. I have been trying all day and I still can't find the answer. First of all how do I start my imageadapter class and how the hell can I write additional methods into the class and then execute them in the fragment class?
public class ImageFragment extends Fragment {
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_image, container, false);
GridView gridView = (GridView)getView().findViewById(R.id.gridView);
gridView.setAdapter(new imageadapter(getContext()));
}
}
but why does this then not work ?
public class ImageFragment extends Fragment {
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_image, container, false);
}
#Override
public void onViewCreated(#NonNull final View view, #Nullable Bundle savedInstanceState) {}
GridView gridView = (GridView)getView().findViewById(R.id.gridView);
gridView.setAdapter(new imageadapter(this));
}
I still get errors by the words this and the setAdapter.
All you need to do is add an onViewCreated method where you can do call your methods and other stuff. Here's my code.
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_upcoming, container, false);
}
#Override
public void onViewCreated(#NonNull final View view, #Nullable Bundle savedInstanceState) {
//you can call your methods and find your views in here
setHasOptionsMenu(true);
final FloatingActionButton fab = view.findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(), CreateEditAppointmentActivity.class);
startActivityForResult(intent, RC_ADD_CLIENT);
}
});
coordinatorLayout = view.findViewById(R.id.upcomingLayout);
}
I have two fragment which i want to pass data from one fragment to another,the bundle has value from first fragment when sending but not receiving in another fragment.Here is the code:
First Fragment :
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.customer_one,container,false);
edemail = v.findViewById(R.id.ed_email);
edpass = v.findViewById(R.id.ed_pass);
btn = v.findViewById(R.id.btn_next);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
email = edemail.getText().toString().trim();
password = edpass.getText().toString().trim();
Customer_Frag2 cf2 = new Customer_Frag2();
Bundle bundle = new Bundle();
bundle.putString("Email",email);
bundle.putString("Password",password);
cf2.setArguments(bundle);
Log.d("Test2",bundle.toString());
}
});
return v;
}
Second Fragment:
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable
ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.customer_two,container,false);
Bundle bundle = getArguments();
if(bundle!=null){
email = bundle.getString("Email");
pass = bundle.getString("Password");
}
Log.d("Test",email+pass);
return v;
}
I have a fragment and have linear layout that contains 2 simple card views.
How can I make card view clickable cardviews?
I have searched, but all topics are about cardviews in recycler view ... But I have a simple clickable cardview.
public class popFragment extends Fragment {
public popFragment()
{
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view= inflater.inflate(R.layout.popfragment,container,false);
return view;
}
}
You can simply assign id in your layout xml to each card view. then in oncreateView() of the fragment bind the view and use mycardView.setOnclickListener.... .
public class popFragment extends Fragment {
private CardView cardView1;
private CardView cardView2;
public popFragment()
{
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view= inflater.inflate(R.layout.popfragment,container,false);
cardView1 = view.findViewById(R.id.my_card_view_1);
cardView2 = view.findViewById(R.id.my_card_view_2);
cardView1.setOnClickListener(v->{
//set on click functions here
});
cardView2.setOnClickListener(v->{
//set on click functions here
});
return view;
}
}
do not forget to assign the corresponding ids in your layout.xml
Can't get this working, why am I getting "requestFeature() must be called before adding content"?
this is a Fragment.
#Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
getActivity().requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
final View rootView = inflater.inflate(R.layout.expand, container, false);
getActivity().setContentView(R.layout.expand);
getActivity().getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
ExpandList = (ExpandableListView) rootView.findViewById(R.id.exp_list);
PD = new ProgressDialog(getActivity());
PD.setMessage("Loading.....");
PD.setCancelable(false);
makejsonobjreq();
return rootView;
}
When fragment is running, context.getActivity() is not null but when it turns to onPause() method and resumed back then context.getActivity() method returns null.
#Override public View onCreateView(LayoutInflater inflater,
ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.levelmission, container, false);
initComponents(view);
return view;
}
If you use
setRetainInstance(true);
you should reset your activity each time you recreate your view so something like :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
view = inflater.inflate(R.layout.levelmission, container, false);
initComponents(view);
mActivity = getActivity();
return view;
}
then use mActivity instead of context.getActivity();
