Webview inside Nestedscrollview/Scrollview missing contents

Question

I have a webview which is placed insde a nestedscrollview. Problem i am facing is webview is not loading the full page. Instead it loads a part of the page and after that it keeps the bottom space blank (white).

I have tried with scrollview as well.

Output I am getting:

My Code for webview:

private ImageButton backButton;
    private WebView webView;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_article);

        backButton = findViewById(R.id.backButton);
        webView=(WebView)findViewById(R.id.webView);
        webView.setWebViewClient(new MyBrowser());
//        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
//            descriptionView.setText(Html.fromHtml(data, Html.FROM_HTML_MODE_COMPACT));
//        } else {
//            descriptionView.setText(Html.fromHtml(data));
//        }
        webView.getSettings().setJavaScriptEnabled(true);

        webView.loadUrl("file:///android_asset/html/test.html");

        backButton.setOnClickListener(this);
    }

    private class MyBrowser extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }

You can place your NestedScrollView inside Coordinator layout and have to disable scrolling behavior and also place layout behavior if you are using app bar.

<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:nestedScrollingEnabled="false"
app:layout_behavior="appbar_scrolling_view_behavior">
