我用官方指南创建了一个全屏对话框
问题是，我的工具栏与状态栏重叠，我不知道如何解决这个问题。

对话框片段

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();
            }
        });
}
}

活动创建对话框

@Subscribe
public void showNewAccountDialog(OttoMessages.Login.ShowNewAccountDialog evt) {
    FragmentManager fragmentManager = getSupportFragmentManager();
    CreateAccountDialogFragment newFragment =
            new CreateAccountDialogFragment();

    boolean isLargeLayout = false;
    if (isLargeLayout) {
        newFragment.show(fragmentManager, "dialog");
    } else {
        FragmentTransaction transaction = fragmentManager.beginTransaction();
        transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
        transaction.add(android.R.id.content, newFragment)
                .addToBackStack(null).commit();
    }
}

编辑

从v21样式中删除StatusBarTransparency后，它看起来像
