hide / show action bar in fragment

I have MainActivity extends AppCompatActivity. In that 3 fragments which can be changed by sliding gesture. I want to remove action bar in middle one. And Add action bar again when user slide in 1st or 3rd fragment.

I have below code:

@Override
public void setMenuVisibility(boolean menuVisible) {
    super.setMenuVisibility(menuVisible);
    if(menuVisible && getActivity()!=null){
        getActivity().getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }
}

@Override
public void setMenuVisibility(boolean menuVisible) {
    super.setMenuVisibility(menuVisible);
    if(menuVisible){
        getActivity().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }
}

But, it's giving me below warning:

Skipped 45 frames! The application may be doing too much work on its main thread.

I tried to put that in:

getActivity().runOnUiThread(new Runnable() {
    @Override
    public void run() {
         // hide / show action bar...
    }
});

App is lagging. How can I make it smooth?

Add the following code snippet in the onResume callback of the middle Fragment

AppCompatActivity activity = (AppCompatActivity) getActivity();
if (activity != null) {
    activity.getSupportActionBar().hide();
}

and in the onResume callback of the other two Fragments add 

AppCompatActivity activity = (AppCompatActivity) getActivity();
if (activity != null) {
    activity.getSupportActionBar().show();
}
