NestedScrollView and WebView height issue

I use new

android.support.v4.widget.NestedScrollView
and I faced with issue.

Here is my layout:




<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="250dp">

<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.7">

<!-- some views inside -->

</RelativeLayout>

<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:layout_collapseMode="pin"
/>

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

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

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

<WebView
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>

</android.support.v4.widget.NestedScrollView>




I need to load html inside textView, so I make:

content.setText(Html.fromHtml(htmlString));


And it looks strange. My textview placed at the bottom of screen.
initial state

After I swipe on the text it starts to look normal.
after swipe

And I think textview is not only view with these issue.
I tried use webview, but it even does not show content (I think due to incorrect height computation).
So I need webview or textview to correct work with
NestedScrollView
.

P.S. If I set textview height in
dp
then text looks correctly, but I need
wrap_content
for height.

Finally I need to use
WebView
. Alex Facciorusso answer partly works, but I faced with another issue. When
WebView
content has some specific height then I can see part of the content, but I can't scroll down.
Example:
