I want use in Fragment a AsyncTask and use in AsyncTask findViewById.
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.category,
container, false);
View myFragmentView = inflater.inflate(R.layout.category, container, false);
cont=getActivity();
new ProgressTask(cont, myFragmentView).execute();
}
private class ProgressTask extends AsyncTask <Void,Void,Void>{
private Context mContext;
private View rootView;
public void RecuperarComentarisFoto(Context context, View rootView){
this.mContext=context;
this.rootView=rootView;
}
LinearLayout barLayout = (LinearLayout) rootView.findViewById(R.id.barLayout);
[...]
He say to me that cont=getActivity(); cannot be resolved to a variable.
What should I setfor cont?
Thanks

I trying to create BottomSheetDialogFragment with rounded corners which contain fragment container.
I did the correct drawable and apply to xml of this fragment.
code:
public class ContainerFragment extends BottomSheetDialogFragment {
#Override
public void setupDialog(Dialog dialog, int style) {
View view = View.inflate(getContext(), R.layout.fragment_delivery_container, null);
dialog.setContentView(view);
// тут делаю так, чтобы фон под удалёнными краями из-за скругления был прозрачным
((View) view.getParent()).setBackgroundColor(getResources().getColor(android.R.color.transparent));
/*getChildFragmentManager()
.beginTransaction()
.add(R.id.container, ProvidersFragment.createInstance(), "TASGGGG")
.commit();*/
}
#NonNull
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
BottomSheetDialog bDialog = (BottomSheetDialog) super.onCreateDialog(savedInstanceState);
...
return bDialog;
}
/* #Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = View.inflate(getContext(), R.layout.fragment_delivery_container, null);
getChildFragmentManager()
.beginTransaction()
.add(R.id.container, ProvidersFragment.createInstance(), "TASGGGG")
.commit();
return view;
}*/
....
}
In the current implementation of the code, everything is fine (corners are rounded), only the fragment transaction is commented out. If i'll uncomment, it will throw an error that the "fragment does not have a View". Accordingly, if i'll uncomment onCreateView, then edges of this View appear and I can not do anything with this
I want to open BottomSheetDialog from fragment. Before it, I tried opening BottomSheetDialog at activity and it worked. I use the same code and replace the getSupportFragmentManager with getChildFragmentManager. I also tried replacing the getSupportFragmentManager with getActivity().getSupportFragmentManager . Is there a solution?
public class MainFragment extends Fragment implements BottomSheetDialog.BottomSheetListener {
private TextView mTextView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_beranda, container, false);
Button buttonOpenBottomSheet = findViewById(R.id.button_open_bottom_sheet);
buttonOpenBottomSheet.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
BottomSheetDialog bottomSheet = new BottomSheetDialog();
bottomSheet.show(getChildFragmentManager(),"BottomSheet");
}
});
}
}
Try BottomSheetDialogFragment
ModalBottomSheetDialogFragment.Builder()
.add(R.menu.menu_options)
.show(childFragmentManager, "my_bottom_sheet")
in adapter
holder.nameexam2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Bundle bundle = new Bundle();
bundle.putString("dataList.get(position).getId()",dataList.get(position).getId());
Videos_botttomnav video= new Videos_botttomnav();
video.setArguments(bundle);
}
}
in fragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String str =getArguments().getString("dataList.get(position).getId()");
return view;
}
It invokes null pointer exception in getString(). how to resolve it.enter code here
I resolved the problem by adding childclicklistener in Recyclerview instead of sending data from adapter to fragment.
public class Fragmentone<Interface1> extends Fragment{
public Interface1 Interface;
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
Interface = new Interface1 (this);
return inflater.inflate(
R.layout.fragment_two, container, false);
}
}
it is showing an error
Cannot instantiate the type Interface1
How do I call MainActivityFragment from AppCompatActivity in Android? (I am new to Android.)
Code
main activity
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create new fragment and transaction
}
}
Fragment
public class MainActivityFragment extends Fragment {
ArrayAdapter mforecastadapter;
ListView list_view;
public MainActivityFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootview= inflater.inflate(R.layout.fragment_main, container, false);
String Items[] = {"Sandeep", "Santhosh", "Sangeetha", "Basil", "bibhas", "sumanth", "praveen"};
List<String> weekforecast=new ArrayList<>(Arrays.asList(Items));
mforecastadapter=new ArrayAdapter<String>(getActivity(),R.layout.fragment_main,R.id.list_item_forecast_textview,Items);
list_view = (ListView) rootview.findViewById(R.id.listView);
list_view.setAdapter(mforecastadapter);
return rootview;
}
}
Don't really know what you mean by "call", but if you want to instantiate a fragment in an Activity, write this in your Activity:
FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
YourFragment frag = new YourFragment ();
ft.replace(R.id.container_for_fragment, frag);
ft.commit();
Notice R.id.container_for_fragment is your xml attribute for containing the fragment instance. it can be <fragment>, <FrameLayout>.
This is the most basic way to do that. You can find some more examples on SO, how to use fragments BackStack, etc.
You can also use add() instead of replace() in FragmentTransaction, depends on your need.
I hope it helps you.
