FrameLayout does not match the height of NestedScrollView

Question

I have a FrameLayout inside a NestedScrollView, as

<android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#000000">

But the FrameLayout is not filling the height of the NestedScrollView. How might I fix this?

doing `android:layout_gravity="center"` or `android:layout_gravity="center|fill_vertical"` does not seem to work — learner, Nov 27 '15 at 17:41
`android:fillViewport="true"`check this Add it in `android.support.v4.widget.NestedScrollView` — Syed Qasim Ahmed, Nov 27 '15 at 17:53

Check This Solution
Use fillViewport="true" this attribute causes the scroll view’s child to expand to the height of the ScrollView if needed. When the child is taller than the ScrollView, the attribute has no effect.

 <android.support.v4.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
      android:fillViewport="true"
            app:layout_behavior="@string/appbar_scrolling_view_behavior">

I had already tried `android:fillViewport="true"`. But when I do I get a nullPointerException at line `setContentView(R.layout.activity_main);` – learner Nov 27 '15 at 18:02
Ok I got it I think you should use this whole `android.support.v4.widget.NestedScrollView` inside linear layout – Syed Qasim Ahmed Nov 27 '15 at 18:04
It seems something else was causing the crash. So thanks (although I had already tried fillViewport). I clean the project and now it's working and I don't know why it was failing. – learner Nov 27 '15 at 18:12
