it is containing in

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

But in the layout editor it is showing

How can I remove the spacing above?

Answer 1

The problem is with your Activity where you had inflated the Fragment. Actually, i tried it on My system and I'm Getting Proper result.

Check Your Activity's Layout where the FrameLayout is Used.

2nd Possbility

Check your May be Your Theme is Changing this . Check all the possibilities
