FragmentActivity error Android Studio

Hi i am creating an activity with 4 selection in drawerlayout. Once the user select, a fragment will appear.
First I use Fragment and it run but when I try to convert it into FragmentActivity, i got an error on this line -
fragmentManager.beginTransaction().replace(R.id.main_fragment_container,
fragment).commit();
private void selectItemFragment(int position){
FragmentActivity fragment = null;
FragmentManager fragmentManager = getSupportFragmentManager();
switch(position) {
default:
case 0:
fragment = new FragmentDoctor();
break;
case 1:
fragment = new FragmentHospital();
break;
case 2:
fragment = new FragmentPharmacy();
break;
case 3:
fragment = new FragmentClinic();
break;
}
fragmentManager.beginTransaction().replace(R.id.main_fragment_container, fragment).commit();
FRAGMENT DOCTOR
public class FragmentDoctor extends FragmentActivity {
GoogleMap map;
public FragmentDoctor() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_doctor);
setUpMapIfNeeded();
}
private void setUpMapIfNeeded() {
if (map == null){
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
if (map != null){
setUpMap();
}
}
}
private void setUpMap() {
map.setMyLocationEnabled(true);

FragmentDoctor should extend from Fragment not from FragmentActivity
change this code
public class FragmentDoctor extends FragmentActivity {
like this
public class FragmentDoctor extends Fragment {
and
private void selectItemFragment(int position){
FragmentActivity fragment = null;
FragmentManager fragmentManager = getSupportFragmentManager();
switch(position) {
default:
case 0:
fragment = new FragmentDoctor();
break;
case 1:
fragment = new FragmentHospital();
break;
case 2:
fragment = new FragmentPharmacy();
break;
case 3:
fragment = new FragmentClinic();
break;
}
if(fragment != null) {
fragmentManager.beginTransaction().
replace(R.id.main_fragment_container, fragment).commit();
}

As below
import android.support.v4.app.FragmentActivity;
FragmentActivity is part of support-v4 library..
So please add below dependency to your gradle file :
compile 'com.android.support:support-v4:23.0.1'
You can also add this library by following below steps in Android Studio :
Select File
Select Project Structure
Select app
Select dependencies
Click on '+'
Select library dependency
Select support v4 library and
Press 'OK'
Edited :
public class FragmentDoctor extends FragmentActivity {
And also From your edited code I have noticed that you are extending FragmentActivity not Fragment.
So please follow below link for more information on How to create Fragment with FragmentActivity :

Why Sliding Menu Can't Close in Android

The method getSupportFragmentManager() is undefined for the type Context

The error The method getSupportFragmentManager() is undefined for the type Context occur when i used getSupportFragmentManager() inside my oncreateview.
Different context type reference was used to overcome this error but none of these works:
e.g. globalContext = container.getContext(); globalContext = getActivity().getApplicationContext();
getSupportFragmentManager() can be set only in FragmentActivity. My question is if there is a way to reference getSupportFragmentManager().
My fragment.
public class HomeFragment extends Fragment implements
ActionBar.TabListener {
public HomeFragment(){}
Context globalContext;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_home, container, false);
globalContext = this.getActivity();
actionBar = getActivity().getActionBar();
android.support.v4.app.FragmentManager fm = globalContext.getSupportFragmentManager(); // getting error The method getSupportFragmentManager() is undefined for the type Context }}
mAdapter = new TabsPagerAdapter(fm);
}
}
}
the tabhostlistner adapter.
import android.support.v4.app.FragmentManager;
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fragmentManager) {
super(fragmentManager);
}}

}

1) Create the member variable:
private FragmentActivity context;
2) Override the onAttach method of your fragment:
#Override
public void onAttach(Activity activity) {
context = (FragmentActivity) activity;
super.onAttach(activity);
}
3) Get the support FragmentManager like this:
FragmentManager fm = context.getSupportFragmentManager();

In Kotlin
bottomSheetDialogFragment.show((context as FragmentActivity).supportFragmentManager,
bottomSheetDialogFragment.tag)

I am 100% sure that you are not importing the right package for the support Fragment class
make sure that your Fragment import in your HomeFragment look like this:
import android.support.v4.app.Fragment;

you can access Fragment manager in your getView method like below
((Activity)context).getFragmentManager().beginTransaction().replace(R.id.content_frame, fragment).commit();
where context is an activity ref passed in adapter class
like
public ActorAdapter(Context context, int resource, ArrayList<Actors> objects)
{
super(context, resource, objects);
this.context = context;
}
so fragment manager can be accessed for ex. FragmentManager fm = ((Activity)context).getFragmentManager();

Android ActionBarCompat - Navigation Drawer with multiple fragments

Im new to the ActionBarCompat library.I want to develop an app which contains multiple fragments. Here is what i want to do
1.How to open a fragment when user select that from Navigation Drawer.
2.How to set a startup fragment which displays startup layout (example- In Google plus app,first its displays news feeds.when we select profile item from the side menu,then its hide the side menu/Navigation drawer and displays the profile layout)
Currently i have side menu and one fragment.
Here is the tutorial that i used to follow- wptrafficanalyzer

If you are going to use a slide out menu I recommend you use this slidemenu library I use it in my applications and it allows you to place whatever you want in the slide out menu, the menu is just a frame layout and you can put whatever you want in it (Listview, GridView, or even just a picture)

I am assuming by side menu you meant Navigation Drawer. You can find an answer in the below link.
Navigation Drawer with backword compatibility android
Do read
http://developer.android.com/design/patterns/navigation-drawer.html
Fragment is hosted by a Activity. So you need a container in the activity layout.
<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">
<FrameLayout // container to which you add or replace fragments
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<ListView
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"/>
</android.support.v4.widget.DrawerLayout>
Initially you don't click any item. So initially add fragment1 to the container.
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment1= new Fragment1();
fragTran.add(R.id.content_frame, fragment1);
fragTran.commit();
On click of listitem based on the position
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment3= new Fragment3();
fragTran.replace(R.id.content_frame, fragment3);
fragTran.commit();

Hi check this code

How to get items in Navigation Drawer to change view

I want to make an simple app with a Navigation Drawer, which can open other views (News, Information, Gallery, Contact etc). So I opened up the latest Android Studio, made a new project that is compatible with API8>API19, to get maximum reach.
I chose the preset Navigation Drawer and clicked finish. I have figured out to change the names of the items in the Navigation Drawer, but how do I get these items to redirect to a new view?
I have tried implementing the setOnItemClickListener into the MainActivity as the Navigation Drawer site says on http://developer.android.com. But I can't seem to figure out how it all ties together, and it wont work.
tl;dr: I need help with making the items in the Navigation Drawer launch a new view/fragment, and probably an explanation on how it all works.
Here is the app project (Android Studio) https://www.dropbox.com/s/qfz9oul62dzt3rr/NTI_SHOWCASE.zip

Would it be better and easier to create an app with the Navigation Drawer from scratch, rather than using a pre-built?
Help is much appreciated.

Well, I'll left this here in case someone needs help switching Fragments in an "Android Studio" Navigation Drawer project
The answer proposed by user2511882, uses the following:
fragment = new FirstFragment();
But the code generated by "Android Studio" uses:
fragment = FirstFragment.newInstance();
(which is a better practice; see why HERE)
That's why his answer doesn't work for your project.
In your case, you have to use something like:
#Override
public void onNavigationDrawerItemSelected(int position) {
Fragment fragment = null;
switch (position){
case 0:
fragment = FirstFragment.newInstance(position + 1);
break;
case 1:
fragment = SecondFragment.newInstance(position + 1);
break;
}
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment)
.commit();
}
In "Android Studio" it is also a good practice to read the comments and "TODOS" incorporated in the auto generated code.
best regards.

You will need to setup a setOnItemClickListener on your drawerLayout(the id of the listview in your xml file)
Example:
drawerLayout.setOnItemClickListener(new ListView.onItemClickListener){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
displayView(position);
}}
private void displayView(int position) {
switch (position) {
case 0:
fragment = new FirstFragment();
break;
case 1:
fragment = new SecondFragment();
break;
if (fragment != null) {
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_layout_id, fragment).commit(); //
And you need to make separate java class for the FirstFragment and SecondFragment with whatever content you need.

get Item position in navigation view you can set first 0th position menu default by
navigationView.getMenu().getItem(0); // default selected menu
displayview(navigationView.getMenu().getItem(0));
private void setupDrawerContent(final NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
displayView(menuItem);
return true;
}
});
}
public void displayView(MenuItem menuItem) {
Fragment fragment = null;
switch (menuItem.getItemId()) {
case R.id.nav_home:
// fragment = new CheeseListFragment();
break;
case R.id.nav_messages:
fragment = new MessageFragment();
break;
}
if(fragment != null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, fragment)
.commit();
menuItem.setChecked(true);
mDrawerLayout.closeDrawers();
}
}

get Item position in navigation view you can set first 0th position menu default by
navigationView.getMenu().getItem(0); // default selected menu
