How to change the title in the navigation box

Question

I would like the name in the menu to change by the name of the fragment that was clicked. for the code below, I understand that the actual title in each fragment is “Home”, and it does not change. but I found that when I click on an item in the menu, the name changes for a second and returns to the "Home" heading. I implemented ondrawer, but still I do not know what can do this.

my code is:

Answer 1

Ok, I found the problem, your answer was good, and I really change the title every time from the snippet, but also, I need to disable this line:

 getSupportActionBar().setTitle(mDrawerTitle); 

from onDrawerOpened and onDrawerClosed

Answer 2

Set it for the whole fragment. That should do the job!

 @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.id.your_fragment_layout, container, false); getActivity().setTitle("<your title>"); return rootView; } 

Answer 3

try the following:

 @Override public void onResume() { super.onResume(); ((AppCompatActivity) getActivity()).getSupportActionBar().setTitle("Your Title"); } 

Answer 4

Do not specify an ActionBar title, set the title to an Activity, you can do this from an action or fragment. For activities:

 setTitle("New Title"); 

or for fragment:

 getActivity().setTitle("New Title"); 

Answer 5

add this to your snippet

 getActivity().setTitle("title"); 

Add remove this line below from the Drawer action

 getActivity().setTitle("title");
