My BaseDrawerActivity extends BaseActivity and I have a Toolbar in BaseActivity.
The toolbar shows with no issues in classes that extend BaseActivity, but ALL classes that extend BaseDrawerActivity just show a blank toolbar. The nav drawer works fine.
When I had one main activity class (BaseActivity + BaseDrawerActivity) the toolbar showed no problem and the nav drawer worked.
Why is my implementation here not showing the Toolbar? I debugged and getToolbar() is returning the toolbar for sure.

R.layout.toolbar_updating_spinner, null, false);
int dpInPixels = (int) getResources().getDimension(R.dimen.toolbar_updating_spinner);

Gravity.END);
mToolbar.addView(mUpdatingSpinner, spinnerLp);
}
I found the answer although I don't fully understand it.
I basically called setupToolbar() again in my BaseDrawerActivity right before I call setupNavDrawer() and for some reason this fixed it.
I think the reference to the Toolbar from BaseActivity wasn't retrieving correctly (even though I debugged and it had a reference to it). Another thing I tried is setSupportActionBar(mToolbar) right before setting up the nav drawer but that didn't work.
If anyone has any ideas as to why I have to setup the toolbar again in order for it to show I'd be glad to hear it!
