getSupportActionBar from inside of Fragment ActionBarCompat

Question

I\'m starting a new project that uses the AppCompat/ActionBarCompat in v7 support library. I\'m trying to figure out how to use the getSuppor

Answer 1

in your fragment.xml add Toolbar Tag from support library

Now how we can control it from MyFragment class? let's see

inside onCreateView function add the following

mToolbar = (Toolbar) view.findViewById(R.id.toolbar);
((AppCompatActivity)getActivity()).setSupportActionBar(mToolbar);

//add this line if you want to provide Up Navigation but don't forget to to 
//identify parent activity in manifest file
((AppCompatActivity)getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);

and if you want to add items to the toolbar within MyFragment you must add this line inside onCreateView function

        setHasOptionsMenu(true);

this line is important, if you forget it, android will not populate your menu Items.

assume we identify them in menu/fragment_menu.xml

after that override the following functions

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.fragment_menu, menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    switch (id) {
        case R.id.action_1:
            // do stuff
            return true;

        case R.id.action_2:
            // do more stuff
            return true;
    }

    return false;
}

hope this helps
