title: Fullscreen DialogFragment overlaps with StatusBar
body: <p>I created a full screen dialog with the <a href="http://developer.android.com/guide/topics/ui/dialogs.html#FullscreenDialog" rel="noreferrer">official Guide</a> </p>
  
  <p>The problem is, that my Toolbar overlaps with the status bar and I cannot figure out how to solve this.</p>
  
  <p><strong>DialogFragment</strong></p>
  
  <pre><code>public class CreateAccountDialogFragment extends BaseDialogFragment {
  
      @Inject
      CreateAccountViewModel viewModel;
  
      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container,
                               Bundle savedInstanceState) {
          //InjectDependencies....
          View rootView = createDataBinding(inflater, container);
          createToolbar(rootView);
  
          return rootView;
      }
  
      private View createDataBinding(LayoutInflater inflater, ViewGroup container) {
          CreateAccountDialogFragmentBinding binding =
                  DataBindingUtil.inflate(inflater, R.layout.create_account_dialog_fragment, container, false);
          binding.setViewModel(viewModel);
          return binding.getRoot();
      }
  
      private void createToolbar(View rootView) {
          Toolbar toolbar = (Toolbar) rootView.findViewById(R.id.toolbar);
  
          // Set an OnMenuItemClickListener to handle menu item clicks
          toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
              @Override
              public boolean onMenuItemClick(MenuItem item) {
                  if (item.getItemId() == R.id.action_save) {
                      viewModel.createAccount();
                  }
                  return true;
              }
          });
  
          // Inflate a menu to be displayed in the toolbar
          toolbar.inflateMenu(R.menu.create_account_menu);
          toolbar.setTitle(R.string.create_account);
          toolbar.setNavigationIcon(R.drawable.ic_cancel);
  
          toolbar.setNavigationOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View v) {
                  dialogFragment.dismiss();
              }
          });

  <p><strong>EDIT</strong></p>
  
  <p>After removing StatusBarTransparency from v21-styles it looks like this
