setImageResource not working

I'm about to set an ImageView with setImageResource, but it's not working. nothing error too. and the logcat seems fine.
Here is my code :
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_item_list_request, container, false);
setHasOptionsMenu(true);
View anotherView = inflater.inflate(R.layout.style_fragment_list_request,container,false);
imgView = (CircleImageView)anotherView.findViewById(R.id.listPhoto);
imgView.setImageResource(R.drawable.pastel_red);
}
Considering that I called and declare the ImageView from another layout. Is at problem if I inflate 2 layouts just for set image for another layout ?
Anything wrong here?

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_item_list_request, container, false);
setHasOptionsMenu(true);
return view;
}
public void onActivityCreated(){
ViewGroup layout = (ViewGroup) getView().findById(R.id.layout_another_view); // need layout for anotherView in fragment_item_list_request.xml
View anotherView = inflater.inflate(R.layout.style_fragment_list_request,container,false);
imgView = (CircleImageView)anotherView.findViewById(R.id.listPhoto);
imgView.setImageResource(R.drawable.pastel_red);
layout.addView(anotherView);
}

What if you do this instead:
View anotherView = inflater.inflate(R.layout.style_fragment_list_request,null,false);

The statement return anotherView; is missing in onCreateView().

use font in Fragment

I tend to use the font fragment and fragment have control over
Why the following code produces an error?
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rooo = inflater.inflate(R.layout.din2, container, false);
TextView tv1=(TextView) rooo.findViewById(R.id.tv1);
Typeface yaghut=Typeface.createFromAsset(getActivity().getAssets(), "font/BKOODB.ttf");
tv1.setTypeface(yaghut);
return rooo;
}
}
this error

onCreateView is supposed only to return the view that represent the fragment. Other operations on the View should be performed in another callback, onViewCreated
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.din2, container, false);
}
#Override
public void onViewCreated (View view, Bundle savedInstanceState) {
TextView tv1=(TextView) view.findViewById(R.id.tv1);
Typeface yaghut=Typeface.createFromAsset(getActivity().getAssets(), "font/BKOODB.ttf");
tv1.setTypeface(yaghut);
}

you need change :
TextView tv1=(TextView) r.findViewById(R.id.tv1);
to
TextView tv1=(TextView) rooo.findViewById(R.id.tv1);
because your TextView with tv1 id's must be on din2 layout.

You are creating a view named rooo but you are returning a view named roo...now replace all roo with rooo as below...
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rooo = inflater.inflate(R.layout.din2, container, false);
TextView tv1=(TextView) rooo.findViewById(R.id.tv1);
Typeface yaghut=Typeface.createFromAsset(getActivity().getAssets(), "font/BKOODB.ttf");
tv1.setTypeface(yaghut);
return rooo;
}
}

How to access a UI element in a fragment?

I have a fragment with a control (a TextView) with id R.id.currentCycleIndicator and want to programmatically set its value from within the fragment.
Both
getActivity().findViewById(R.id.currentCycleIndicator) and
getView().findViewById(R.id.currentCycleIndicator)
return null.
How can I get reference to that TextView inside the fragment code?

Try getting its value in onCreateView() callBack function of your Fragment like below :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_layout, container, false);
TextView textView = (TextView) view.findViewById(R.id.currentCycleIndicator);
return view;
}

You can do that by overriding the onViewCreated function as below :
private TextView tv;
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
tv = (TextView) view.findViewById(R.id.currentCycleIndicator);
}

Inflate your view inside onCreateView and refer to your TextView from there.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.layoutwheretextviewis, container, false);
TextView text= (TextView) view.findViewById(R.id.currentCycleIndicator);
return view;
}

How to get an id of a View inside a Fragment

Hi I am trying to get an id of some View in a Fragment from a string, however it doesn't seem to work... Is there a special case for fragments?
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View singleplayerView = inflater.inflate(R.layout.singleplayer_tab, container, false);
setupMap();
return singleplayerView;
}
private void setupRank() {
TextView view = (TextView) getByStringId("rank0");
view.setText("hello");
}
private final View getByStringId(final String id) {
return findViewById(getResources().getIdentifier(id, "id", getActivi
ty().getPackageName()));
}
So I am trying to set the textView field rank0 in the layout that is used for my fragment... but right now it gets a NUllPointer because it couldnt find the id
Thank you

you can define your Layout In your onCreateView() inside Fragments like this:
View V = new View(getActivity());
V = inflater.inflate(R.layout.fragment_layout,container, false);
Then
TextView SomeField = (TextView)V.findViewById(R.id.TxtSomeField);

Inside fragment, add getActivity before findViewById:
getActivity().findViewById(...);

Try this,
String id;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle extra = getArguments();
id = extra.getString("id", "");
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_calendar_details, container, false);
Button b = (Button) view.findViewById(id);
return view;
}

child already has a parent error showing?

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.myfragment, container,false);
ImageView tv = (ImageView ) v.findViewById(R.id.imageView);
tv.setImageResource(R.drawable.h1);
return tv;
}
why am i getting the runtime error?

Change your above code as below:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.myfragment, container,false);
ImageView tv = (ImageView ) v.findViewById(R.id.imageView);
tv.setImageResource(R.drawable.h1);
return v;
}
The Reason you are getting RuntimeError is you are returning ImageView (tv) for onCreateView which is view for Fragment. But ImageView is a child View of myfragment layout so It cannot be set as View to Fragment so you are getting Runtime Error.
