Fragment layout
Activity Layout

Check if your #InjectViews has correct type. I've used ImageView instead of LinearLayout. That might be your problem too.

Fragment have 2 toolbars, its own and that of activity

I have an HomeAcivity with 4 fragments. 3 of the fragments have no Toolbar of their own and I am showing the Activity's Toolbar in them. However, the 4th Fragment have Toolbar of its own.
Currently I am seeing 2 Toolbars in 4th Fragment, one its own and other that of Activity.How can I hide the Activity's Toolbar and just show its own Toolbar?
Please note that I don't want to update the content of Activity's Toolbar instead of showing new Toolbar inside Fragment. I want to show Fragments own Toolbar and hide that of Activity.
Please help me out.

You can hide activity's toolbar from your 4th fragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_view, container, false);
((ToolbarView)getActivity().findViewById(R.id.toolbarView)).setVisibility(View.GONE);
return rootView;
}
and show activity's toolbar from other three fragments
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_view, container, false);
((ToolbarView)getActivity().findViewById(R.id.toolbarView)).setVisibility(View.VISIBLE);
return rootView;
}

Inflate view in a single fragment

The app I'm currently developing has an action bar with 5 tabs (fragments). One of these fragment shows an alert dialog, but the layout is blank. I want to put a background image, so I created a layout for that fragment and used inflater.inflate(...) method to set the layout.
Problem is that line of code sets that layout to ALL fragments. How can I limit it just to the fragment I need? Here's my code:
public class MyFragment extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
//...
AlertDialog ad = new AlertDialog.Builder(getActivity()).setTitle("Title")
//...
ad.show();
inflater.inflate(R.layout.fragment_my, container); //this is the layout I want to inflate to my fragment
return super.onCreateView(inflater, container, savedInstanceState);
}
Also tried to replace the last two lines with:
return inflater.inflate(R.layout.fragment_trovami, container);
but i'm getting this error:
07-27 16:19:46.768: E/AndroidRuntime(1998): java.lang.IllegalStateException:
The specified child already has a parent. You must call removeView() on the child's parent first.

Answer :
return inflater.inflate(R.layout.fragment_trovami, container,false);

How to set data to layout inflated by a fragment

I have a FragmentActivity which sets a main layout with 3 tabs. Each tab has it's own fragment which inflates is own layout into main layout.
For example, one of the three Fragments:
public class Fragment1 extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (container == null) {
return null;
}
return inflater.inflate(R.layout.fragment1, container, false);
}
}
When I add all the fragments and connect them with tabs everything works. When I click on tab1, layout of the Fragment1 shows, when I click on Tab2, layout of the Fragment2 shows.
The problem is that when I want to change something in that inflated layout (for example execute setText to textView in fragment1 layout), I receive a NullPointerException in that line and application stops.
This doesn't work:
TextView test = (TextView) findViewById(R.id.fragmentOneText1);
test.setText("Test text!");
How to set data to inflated layout?

You have to inflate your fragment specific layout first by using LayoutInflater and map the control in your Fragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View fragmentView = inflater.inflate(R.layout.R.layout.fragment1, container, false);
TextView text = (TextView) fragmentView.findViewById(R.id.fragmentOneText1);
mTextNoResult=(TextView)fragmentView.findViewById(R.id.text_noresult);
return fragmentView;
}
