Issue with WebView in android

I have the following code to display a web page. Everything in this layout was working fine but when i added the web view, the web view isn't working. Please let me know how to fix this. I also suspect that the problem is with the nesting of the web view because I tried to open the same web page using another sample app with a web view without any parent views and it worked.

<android.support.design.widget.CoordinatorLayout 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:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.ActionBar">


        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar_detail"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="?attr/colorPrimary"
            android:minHeight="?attr/actionBarSize"
            android:theme="@style/ToolbarTheme"
            android:titleTextAppearance="@style/Toolbar.TitleText"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

            <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginLeft="16dp">

                <include
                    android:id="@+id/user_profile_toolbar"
                    layout="@layout/user_name"
                    android:layout_width="match_parent"
                    android:layout_height="72dp" />

            </LinearLayout>

        </android.support.v7.widget.Toolbar>
    </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">


        <LinearLayout

            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            android:orientation="vertical"
            tools:context="com.example.personal.newsfeeder.DetailActivity">

            <WebView
                android:id="@+id/webView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content">
           </WebView>
        </LinearLayout>
    </android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>

Webview inside ScrollView is trouble some layout.. you can try android:fillViewport="true" for NestedScrollView and layout_height="match_parent" for WebView.. remove the unnecessary LinearLayout inside nestedscroll.. just use WebView 

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

Try also webview height change to static height.. if you want.. it might work also

make sure you use latest android support design library

Thank you everyone for trying to help. I figured out the solution. It was not in the layout file at all. The link to load the web page in the line myWebView.loadUrl("xyz")was just empty string and I just forgot to initialize that string correctly.

But I don't think there is any issue here in my layout by using WebView inside the NestedScrollView. It works smoothly for me.

But please do let me know if its not a good practice to use WebView inside the NestedScrollView.
