Fullscreen DialogFragment overlaps with StatusBar

Question

I created a full screen dialog with the official Guide

The problem is, that my Toolbar overlaps with the status bar and I cannot figure out how to solve this.

DialogFragment

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();
            }
        });
}
}

Layout

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <data>
        <variable
            name="viewModel"

        <LinearLayout

            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:orientation="vertical">

            <org.altoware.weity.views.BindableEditText
                android:id="@+id/editTextUsername"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:addTextChangedListener="@{viewModel.onUsernameChanged}"
                android:hint="Username"
                android:singleLine="true"/>

            <org.altoware.weity.views.BindableEditText
                android:id="@+id/editTextPassword"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:addTextChangedListener="@{viewModel.onPasswordChanged}"
                android:hint="Password"
                android:inputType="textPassword"
                android:singleLine="true"/>

        </LinearLayout>
    </RelativeLayout>

Toolbar

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout xmlns:android="http://schemas.android.com/apk/res/android"
                                            xmlns:app="http://schemas.android.com/apk/res-auto"
                                            xmlns:tools="http://schemas.android.com/tools"

        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay"/>

</android.support.design.widget.AppBarLayout>

Activity creating Dialog

@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();
    }
}

EDIT

After removing StatusBarTransparency from v21-styles it looks like this

Answer 1

If you want DialogFragment in fullscreen and also want statusbar with your own color, you may add this in onCreate() method on your DialogFragment.

 setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme_DeviceDefault_Light_NoActionBar_Fullscreen);

You may also add below code in onCreateView method for status bar color.

 getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
 getDialog().getWindow().setStatusBarColor(getResources().getColor(R.color.colorPrimaryDark));

Answer 2

The problem is in the transaction.add(containerId, fragment) part.

You have it set to: transaction.add(android.R.id.content, fragment), and it is the setting of it to android.R.id.content that is causing the overlap.

Instead, set it to the id of the parent's content frame in the calling activity.

For example, in my code the main activity parent layout was a DrawerLayout, with id of drawer_layout, so my fix was

 MyDialogFragment fragment = new MyDialogFragment ();
 FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
 transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
 transaction.add(R.id.drawer_layout, frag)
            .addToBackStack(null).commit();

Answer 3

After removing the transparency color of the StatusBar I found, that now it is possible to add a padding without the statusbar going white.

The RelativeLayout of my DialogFragment now looks like this.

 <RelativeLayout
      android:paddingTop="24dp"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="@android:color/background_light">

app/src/main/res/values-v21/styles.xml

<resources>>
      <style name="AppTheme.NoActionBar">
          <item name="windowActionBar">false</item>
          <item name="windowNoTitle">true</item>
          <item name="android:windowDrawsSystemBarBackgrounds">true</item>

          <!-- REMOVE THIS LINE 
          <item name="android:statusBarColor">@android:color/transparent</item>
          -->
      </style>
  </resources>

Warning
I have not tested this on other devices than the Nexus 5.
