Strange webview black blinking when scrolling

I am loading the data from a String, and on the first time when I scroll down the webview blinks couple of times.

Here is my code where I load the data:

webview.loadDataWithBaseURL(null, message.getmContent(), "text/html", "UTF-8", null);

And the xml:

    <WebView
        android:id="@+id/web_content"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_above="@+id/footer"
        android:layout_below="@id/message_title"
        android:layout_margin="4dp"
         />

It's also possible to set android:minHeight in xml file and it works fine for me.

<WebView
   android:id="@+id/webView"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:minHeight="200dp"/>

After resolving with the above solution, My WebView autoFocused on scroll down. I resolved the flicker and auto-scroll by:

webView.setFocusable(false);
webView.setFocusableInTouchMode(false);

The solution is adding:

webview.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
webview.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
