Code:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_picture_preview, container, false);
    return view;
}

Layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white">

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/lc_picturePreview"
    android:layout_above="@+id/lc_pictureNavigationBar" />

<LinearLayout
    android:id="@+id/lc_pictureNavigationBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:layout_alignParentBottom="true"
    android:gravity="center"
    android:orientation="horizontal">

    <!--view cause of crash-->
    <view
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="2" />

    <TextView
        android:id="@+id/lc_pictureDelete"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:gravity="right"
        android:paddingLeft="15dp"
        android:paddingRight="15dp"
        android:textColor="@color/White"
        android:textSize="30sp" />

</LinearLayout>

</RelativeLayout>

I encountered this same issue in Activity also when I used view instead of View tag. But found a solution from https://readyandroid.wordpress.com/android-view-inflateexception-binary-xml-file-line-0-attempt-to-invoke-virtual-method-boolean-java-lang-string-equalsjava-lang-object-on-a-null-object-reference-android/ You can found many more Android tricks and solutions from here: https://readyandroid.wordpress.com/

@matteo-adsolutions nothing to do with Calligraphy, you can’t just inflate a view like that. I use Space and View all the time in similar situations. If you remove Calligraphy you will see the same crash.
