Los datos no se cargan en WebView pero se cargan después del bloqueo: desbloquee el dispositivo

I have data with some of the html tag, and I want to display it in webView.

Intenté debajo del código:

String html = "<html><body><font face=\"verdana\" size=\""
                + getResources().getString(R.string.WebView_Font_Size)
                + "\" color=\"rgb(64,64,64)\">"
                + Article.getDetaildescription().replaceAll("h2", "h4")
                + "</font></body></html>";
String mime = "text/html";
String encoding = "utf-8";
Log.e("htmlstring", html);
description.loadDataWithBaseURL(null, html, mime, encoding, null);

Issue is: whenever above code executes, nothing loads in webview. But as soon as I lock device & unlocked it, my webview displays that data.

You may want enable javascript before loading data.

From the jaimin answer I got hint.

My old layout file contain one linear layout in other linear layout, so I change webview's height to wrap content , also change scroll view's width to fill parent & remove one unnecessary LinearLayout.

old layout with issue

<include
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    layout="@layout/header_layout" />

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/title_background"
    android:padding="5dp" >

    <Button
        android:id="@+id/Article_Detail_Share"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_gravity="right|center_vertical"
        android:background="@drawable/button_share" />

    <TextView
        android:id="@+id/Article_Detail_Header"
        android:layout_width="wrap_content"

    </LinearLayout>
</ScrollView>

<include
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    layout="@layout/bottom_layout" />

i know that having webview & gallery inside scroll view is not good approach but its project requirement.
