VideoView starts playing in a wrong fragment using viewpager

Problem: I have a viewPager with 3 fragments, the first one has a videoView. When I change to the second fragment, the video stops and when I change to the third, the same. But when I change from the third fragment to the second one, the video starts playing in the background.
I want the video to play only in the first fragment. How can i solve this problem? Thanks
Here is my code:

When you use an FragmentPagerAdapter, it pre-loads your fragments to left and right of your fragment in focus. So when you scroll from position 0 to 1 to 2, the fragment in position 0 is removed. When you then scroll back to position 1, the fragment in position 0 is re-loaded, which triggers creating the view. If you look at your HomeFragment, you trigger playing video when in OnCreateView().
To resolve this, you need to change how you trigger playing the video from when the Fragment is created to instead be activated when it scrolls into view. You are already halfway there with your empty OnPageChangeListener. You should check the position in onPageSelected() and start the video there instead of in the Fragment's OnCreateView

You have to override setUserVisibleHint method in a fragment where you play video.
public void setUserVisibleHint
#Override
public void setUserVisibleHint(boolean isVisibleToUser)
{
super.setUserVisibleHint(isVisibleToUser);
if (this.isVisible())
{
if (!isVisibleToUser)
{
//pause or stop video
} else {
//play your video
}
}
}

TextView OnClickListener not responding in fragment

I'm new to this fragment coding in Android stuff so I hope this is a simple one for most to answer.
I have a TextView object, 'next', that, when clicked, does not seem to be responding. I want to do a few things when the TextView text is clicked. First, check the String value in the eventName spinner, then Toast the eventID value and finally start a new fragment for the next part of user interaction.
I have not yet implemented the new fragment or a call to the fragment. I assume the way to call the new fragment is with the following code:
NextFragment nextFrag= new NextFragment();
getActivity().getSupportFragmentManager().beginTransaction()
.replace(R.id.Layout_container, nextFrag,"findThisFragment")
.addToBackStack(null)
.commit();
My questions are:
Why is the Toast not being displayed? It seems as though the OnCickListener or the OnClick method isn't triggering the Toast.
Is the code above all that I need to do to call a new fragment and make it active in the current Activity or is there something else that I need to add in the Activity code?

Toast will display if you call show(), So you have to change the following line of code like this
Toast.makeText(getActivity().getApplicationContext(),"Choose an event first",Toast.LENGTH_LONG).show();
You can use the following code sample code to launch the fragment from another fragment
Fragment2 fragment2 = new Fragment2();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragment1, fragment2);
fragmentTransaction.commit();

What I've missing or what I'm doing wrong?

You haven't defined any view for your fragment, so it is unable to find that relevant id thus resulting in Null Pointer Exception. Override onCreateView() method in your fragment and provide a view in that and then write your findViewById code in this method like this
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.layout, container, false);
btn_name= (Button) view.findViewById(R.id.your_button_id);
return view;
}

You can't instantiate view using getActivity() in Fragment.
You have to do like below and remove instantiation from onResume():
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.your_fragment_layout, container, false);
scanBtn = (Button) view.findViewById(R.id.scan_button);
formatTxt = (TextView) view.findViewById(R.id.scan_format);
contentTxt = (TextView) view.findViewById(R.id.scan_content);
scanBtn.setOnClickListener(this);
return view;
}

Simple call notifyDataSetChanged(); when you click in button for refresh your ListView
buttonHeart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
...
notifyDataSetChanged();
}
});

Basically your list view is connected with adapter. You need to notify this adapter to redraw the list view. Can you give more information where exactly your button click listener code is (in which class). If it is inside your adapter class (like I suppose) you can do something like this in your click listener code (some where inside the method public void onClick(View arg0) ) :
YourAdapterClassName.this.notifyDataSetChanged();

Update your adapter constructor to accept the Fragment as a parameter.
Something like :
public CustomAdapter(Context context, int id, HomeFragment fragment) {
this.fragment = fragment;
}
then you call methods using the fragment variable.
fragment.doSomething();
and in this method you can refresh the list using notifyDataSetChanged();

SharedPreferences STRANGE BEHAVIOUR

I am beginner at android developing and i am making very simple app that has a content inside and you can edit the font type and size of the content using settings fragment .
a problem is facing me which when i set my fonts settings it saved well. i close the app and get back to the content activity and it works very well but when i get back to the settings fragment it returns the font type JUST . to its default value.the font size stays at user determinded value .
This is settings fragment code

please help

onItemSelectedListener is called the first time with position = 0.
So you are overriding the preference with "fonts/blacksugar.ttf" when SettingsFragment is created.
You should get "fontType" preference and select it in the Spinner:
Spinner spinner = (Spinner) v.findViewById(R.id.spinner);
ArrayAdapter<String> spinnerAdapter = new ArrayAdapter<>(getActivity(), R.layout.spinner_layout, fonts);
spinner.setAdapter(spinnerAdapter);
spinner.setSelection(spinnerAdapter.getPosition(sharedPreferences.getString("fontType","fonts/blacksugar.ttf")));
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
edit.putString("fontType",fonts[position]).commit();
tester.setTypeface(Typeface.createFromAsset(getActivity().getAssets(),sharedPreferences.getString("fontType","")));
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});

Typeface typeface=Typeface.createFromAsset(getActivity().getAssets(),"fonts/blacksugar.ttf");
textView=(TextView)v.findViewById(R.id.textsets);
textView.setTypeface(typeface);
I think your problem could be here. You are setting the typeface of the textview yourself and not reading from the file.
Also,
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
switch(position){
case 0:edit.putString("fontType",fonts[0]).commit();
tester.setTypeface(Typeface.createFromAsset(getActivity().getAssets(),sharedPreferences.getString("fontType","")));
break;
case 1:edit.putString("fontType",fonts[1]).commit();
tester.setTypeface(Typeface.createFromAsset(getActivity().getAssets(),sharedPreferences.getString("fontType","")));
break;
case 2:edit.putString("fontType",fonts[2]).commit();
tester.setTypeface(Typeface.createFromAsset(getActivity().getAssets(),sharedPreferences.getString("fontType","")));
break;
case 3:edit.putString("fontType",fonts[3]).commit();
tester.setTypeface(Typeface.createFromAsset(getActivity().getAssets(),sharedPreferences.getString("fontType","")));
break;
case 4:edit.putString("fontType",fonts[4]).commit();
tester.setTypeface(Typeface.createFromAsset(getActivity().getAssets(),sharedPreferences.getString("fontType","")));
break;
case 5:edit.putString("fontType",fonts[5]).commit();
tester.setTypeface(Typeface.createFromAsset(getActivity().getAssets(),sharedPreferences.getString("fontType","")));
break;
case 6:edit.putString("fontType",fonts[6]).commit();
tester.setTypeface(Typeface.createFromAsset(getActivity().getAssets(),sharedPreferences.getString("fontType","")));
break;
}
}
The switch statement is redundant. Just do,
edit.putString("fontType",fonts[position]).commit();
