Issue that I have found reproduce only on devices and emulators with API level 16 (4.1.2) + support library v4.
There is quite complicated structure: ActionBarActivity->Fragment(Outer)->ViewPager->Fragment(Inner, several instances).Each fragment inside ViewPager (Inner Fragments) changes ActionBar title and adds its own MenuItems. After replacing Outer fragment (that owns ViewPager) with another one (the same class: Outer) MenuItems (that first Inner fragment has added) become invisible and title trimmed(view that contain title do not re-sized). After swiping to the second Inner fragment and back everything return in proper state.

I have tried checking all the related posts from the internet and can't find a decent tutorial on YT. Can someone tell me what is going on here?
Add following line in onCreateView() method
setHasOptionsMenu(true)
Also add below line in onViewCreated() method
(activity as AppCompatActivity?)!!.setSupportActionBar(customToolbar as Toolbar?)
Where customToolBar is the id of the toolbar added in xml file
Add this in your onCreateView method
setHasOptionsMenu(true);
I Implemented the Navigation Drawer in my Fragment but it always shows a grey padding above it .Same was the case with Fragment but i removed it by adding android:fitsSystemWindows="false". But this fails to remove the padding above the Navigation Drawer . How can i avoid this ?
This is my Fragment :

return rootView;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
context = getActivity();
mDrawerLayout = (DrawerLayout)view.findViewById(R.id.queries_drawer_layout);
setHasOptionsMenu(true);
((AppCompatActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mDrawerLayout.setDrawerListener(new DrawerLayout.DrawerListener() {
#Override
public void onDrawerSlide(View view, float v) {
}
#Override

mSlideState=true;
}
#Override

}

}
});
}

I am stuck trying to put the content from my fragment into the main view in android studio.
The app compiles and runs. But when I choose an item in the navigation drawer (sliding menu) to the item in the list with the fragment: it is blank.

You need to call super.onCreateView(...) in the fragment's onCreateView method for the fragment to be drawn correctly.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
Also, I'd recommend doing the following, since there are a few logical errors:
View rootView = inflater.inflate(R.layout.fragment_masjidharam, container, false);
YouTubePlayerView youTubePlayerView = null;
// THIS IS ALWAYS FALSE. Comment it out or else it'll never get set.
// if (youTubePlayerView != null)
youTubePlayerView = (YouTubePlayerView) rootView.findViewById(R.id.youtube_player);
// Check for not-null here.
if(youTubePlayerView != null) {
youTubePlayerView.initialize(API_KEY, this);
}
I am trying to implement both of these features into a Fragment but so far no success.

Any help would be appreciated
You need to refer to its View object (rootView) to call the method like:
ListView lista = (ListView) rootView.findViewById(R.id.listView1);
I am assuming that lay_menufragment xml contains listView1 as an ID to the ListView element.
Fix the other similar compile error the same way.
I don't see how you're launching FmMenu fragment maybe via Intent, layout, or whatever. Please post the layout file(s) also like lay_menufragment, to save time.
I can't to get the button from fragment, what's wrong?
Recieve a uncaught exception - nullpointerexception;
Button can't be found.
Early all will be find, but after update android sdk, all is changed ((

p.s. sorry for my english
You are trying to search inside Activity's layout, and your widgets are inside a Fragment's layout.
Put your logic inside your PlaceHolderFragment class:
public static class PlaceholderFragment extends Fragment implements OnClickListener {
public PlaceholderFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container,
false);
mplayer = new MediaPlayer();
rgroup = (RadioGroup) rootView.findViewById(R.id.radioGroup1);
play = (Button) rootView.findViewById(R.id.play);
pause = (Button) rootView.findViewById(R.id.pause);
play.setOnClickListener(this);
pause.setOnClickListener(this);
return rootView;
}
#Override
public void onClick(View v) {
}
}
P.S. Салам алейкум =)
