Android videoView not showing inside fragment

Hey all I am having a little bit of an issue with trying to call a fragment that has the videoview within it into my current fragment page.
When I click on the test button I set up it goes through the code without error but never shows the video fragment - I even gave it a background color of red so I could see it load into my current view.
My goal here is just to send a parameter of the video path to the video fragment videoview player and start playing it.
videoPlay.java
public class videoPlay extends Fragment {
public videoPlay(){
//constructor
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout._fragvideoplay, container, false);
MediaController mc= new MediaController(getActivity());
VideoView view = (VideoView)rootView.findViewById(R.id.videoView);
String path = Environment.getExternalStorageDirectory().getAbsolutePath().toString() + "/sddir/Bubble Guppies.mp4";
view.setVideoURI(Uri.parse(path));
view.setMediaController(mc);
view.start();
return rootView;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {

The path to the movie is correct. And the movie is there in the "external" SD card path. Clicking around on the new fragment (videoPlay) yields no video menu (play, remind, pause...) so its not there.
Any help would be great!

fragment with the listview is not being replaced by the fragment with the textview

I want to have a activity with a image and then two fragments, one fragment with a list view and other fragment with a textview.
So, when the image is clicked i want to show the fragment with the list view and when the item on the fragment is clicked i want to replace the fragment with the listview with the fragment with the textview showing the text of the clicked list item.
Im doing this with the code below, but its not working, when an item of the list item is clicked the fragment with the listview is not replaced by the fragment with the textview so the list item text dont appears.
Main activity class:
public class MainActivity extends AppCompatActivity {
private ImageView img;

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fragmentManager = getFragmentManager();
img = (ImageView) findViewById(R.id.imageView);
}
private void addFragment() {
Fragment fragment = new Fragment();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.listviewInFragment, fragment, "frag");
transaction.commit();
}
public void AddFragmentList(View view) {
Fragment fragment = new Fragment();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.container, new FragmentA(), "frag");

How can I add a ViewPager to a Navigation Drawer Item in Android application?

I want to add a viewPager for main fragment in my android app.
This is the xml file for main fragment
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</RelativeLayout>
This is the Java code for Main Fragment
public class MainFragment extends ListFragment {
private static final String TAG = MainFragment.class.getSimpleName();
private StudentsDBHandler studentsDBHandler;
public MainFragment() {
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
studentsDBHandler = new StudentsDBHandler(getActivity());
View rootView = inflater.inflate(R.layout.main_fragment, container, false);
displayStudents();
return rootView;
}
private void displayStudents() {
List<Student> studentList = studentsDBHandler.getAll();
ArrayAdapter<Student> list = new ArrayAdapter<>(getActivity(), R.layout.item_student, studentList);
setListAdapter(list);
}
}

You have a DrawerLayout page. It's about your drawer contains.
İn the DrawerLayout XML
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
add this code below
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
write this code and setup your View pager like example
viewPager=(ViewPager)findViewById(R.id.viewPager);
FragmentManager fm=getSupportFragmentManager();
viewPager.setAdapter(new MyAdapter(fm));
}
class MyAdapter extends FragmentPagerAdapter{
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
if(position==0)
fragment= new Home1();
if(position==1)
fragment=new Home2();
return fragment;
}
#Override
public int getCount() {
return 2;
}
}
}
I hope Help you

You try to set text on view, but this view wasn't created, this fragment wasn't created. If You want to set text from activity you can pass bundle to fragment arguments with that text, and in fragment chceck bundle and set text. Later if you want to change text in this fragment then you can use your function.
public class TabFragment1 extends Fragment {
private TextView tv;
public static TabFragment1 create(String text){
Bundle b = new Bundle();
b.putString("textdata",text);
TabFragment1 f = new TabFragment1();
f.setArguments(b);
return f;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.tab_fragment_1, container, false);
tv = (TextView) view.findViewById(R.id.textView);
if(getArguments()!=null){
tv.setText(getArguments().getString("textdata"));
}
return view;
}
public void setText(String text){
tv.setText(text);
}
}
In your activity create this fragment using static method:
TabFragment1 t1 =TabFragment1.create("HELLO WORLD");
Hardcore execution of your base code is:
new Handler().postDelayed(new Runnable(){t1.setText("HELLO WORLD");},300);

How to go one Fragment to another when I will click on TextView Id?

How to go one Fragment to another when I will click on TextView Id?
Error shows:
java.lang.ClassCastException: com.example.tripigator.Overview cannot be cast to android.app.Activity.
and error comes from these lines :
TextView overview = (TextView) findViewById(R.id.txt_overview);
overview.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(ProjectOverview.this, Overview.class);
startActivity(intent);
}
});
So please anybody help me how to move from one fragment to another by clicking text item.
ProjectOverview class :
public class ProjectOverview extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.project_overview);
initialingpaging();
TextView overview = (TextView) findViewById(R.id.txt_overview);
overview.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(ProjectOverview.this, Overview.class);
startActivity(intent);
}
});
}
private void initialingpaging() {
// TODO Auto-generated method stub
List<Fragment> fragments = new Vector<Fragment>();
fragments.add(Fragment.instantiate(this, Overview.class.getName()));
fragments.add(Fragment.instantiate(this, Highlight.class.getName()));
mPageAdapter = new PageAdapter(this.getSupportFragmentManager(), fragments);
ViewPager pager = (ViewPager)findViewById(R.id.viewpager);
pager.setAdapter(mPageAdapter);
}
}
Two Fragment Classes:
public class Overview extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState)
{
if(container == null)
{
return null;
}
return (LinearLayout) inflater.inflate(R.layout.overview,container,false);
}
}
public class Highlight extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
if(container == null)
{
return null;
}
return (LinearLayout) inflater.inflate(R.layout.highlight,container,false);
}
}
Layout Interface:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent" >

You can't initiate the fragment using Intent.Try this it helps.
Fragment fragment = null;
FragmentManager frgManager;
FragmentTransaction ft;
fragment = new Overview();
ft = frgManager.beginTransaction();
ft.replace(R.id.frame_content, fragment);
ft.addToBackStack(null);
ft.commitAllowingStateLoss();
If you use View-Pager
your_ViewPager.setCurrentItem(position)

you should not use intent in fragment to move another fragment
and check this for whole example http://examples.javacodegeeks.com/android/core/app/fragment/android-fragments-example/
use this.
((yourfragmentActivity) getActivity()).setCurrentItem(1,//desired activity 0=first 1= second and so on
true);
insted
Intent intent = new Intent(ProjectOverview.this, Overview.class);
startActivity(intent);
