Android Fragment ViewPager Is Recreating Options Menu

I am making an android app which has a navigation drawer with fragments being loaded on navigation items.
One of the fragment is containing two tabs which is loading another two fragments via ViewPager.
Everything is working fine as expectations but the problem comes when I select another navigation item from drawer.
One of the tab has options menu but when I go to another fragment and comes back to the earlier, then options menu gets duplicated.

Had to use this code in each fragment in the way to the navigation action where I don't need the options bar
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(android.view.Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
menu.clear();
}

fragment into other fragment

I'm working in an app. I have an activity where I have my menu, I select the options and instance a new fragment, it depends of the option of course. But now I have to create a image swiper inside the fragment (StudyFragment is named)...I don't know how.
I saw some tutorials about how to create it with card view but I don't understand how to use it in my app.
This is my menu.
Sorry for my bad English.

I am trying to switch from one Fragment to another

Reinitialise object before replace fragment
FragmentTransaction transaction=manager.beginTransaction();
like
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
transaction=manager.beginTransaction();
FragmentB fragmentB=new FragmentB();
transaction.replace(R.id.framel,fragmentB);
transaction.addToBackStack(null);
transaction.commit();
}
});

In your main activity make FragmentManager manager and FragmentTransaction transaction as global where they are now. and initialize them in OnCreate() method.
It should be :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
manager=getFragmentManager();
transaction=manager.beginTransaction();
init();
listeners();
}

Change your code with this...
Changes only in MainActivity.java.
public class MainActivity extends AppCompatActivity {
private Button button1, button2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1 = (Button) findViewById(R.id.btn1);
button2 = (Button) findViewById(R.id.btn2);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FragmentA fragmentA = new FragmentA();
openFragment(fragmentA);
}
});
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FragmentB fragmentB = new FragmentB();
openFragment(fragmentB);
}
});
}
private void openFragment(final Fragment fragment) {
FragmentManager fm = getFragmentManager();
FragmentTransaction fragmentTransaction = fm.beginTransaction();
fragmentTransaction.replace(R.id.framel, fragment);
fragmentTransaction.commit();
}
}

I tried your requirement for me its working fine
try it out...and from your code rather than using fragmentmanager() better use getsupportfragmentmanager()
this is my code:
public class Main4Activity extends AppCompatActivity {
Button b1,b2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main4);
b1= (Button) findViewById(R.id.btn1);
b2= (Button) findViewById(R.id.btn2);
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
BlankFragment bf=new BlankFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.container,bf).addToBackStack(null).commit();
}
});
b2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
BlankFragment2 bf2=new BlankFragment2();
getSupportFragmentManager().beginTransaction().replace(R.id.container,bf2).addToBackStack(null).commit();
}
});
}
}

I have written a similar code for you.
private void AddBottomNavigation() {
FragmentManager fragmentManager = getSupportFragmentManager();
Fragment fragment = new HomeFragment();
final FragmentTransaction transaction =
fragmentManager.beginTransaction();
transaction.add(R.id.main_container, fragment).commit();
BottomNavigationView bottomNavigationView = (BottomNavigationView)
findViewById(R.id.bottom_navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(new
BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()){
case R.id.action_home:
fragment = new HomeFragment();
break;
case R.id.action_charge:
fragment = new ChargeFragment();
break;
case R.id.action_rank:
fragment = new RankFragment();
break;
}
final FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.replace(R.id.main_container, fragment).commit();
return true;
}
});
}
Hope this helps you.

ViewPager get invisible after coming from navigation drawer

I didn't understand if that actually what you trying to do but as i understood if you want the TextView moves automatically in one line to show the rest of it make this:
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:freezesText="true"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true" />
and in code after defining it's view make this:
textView.setChecked(true);
