Well-formatted text on Android

Question

Android app: I got a ListView in which each element has: -Three TextViews -One ImageView -One WebView

The content of the WebView is a formatted text: it has two text colors and it is justified. It works perfectly, but the WebView takes half a second to show up. I looked a few questions here on Stackoverflow: no answer worked. I really didn't catch what the problem is, 'cause the text is very short, like thirty characters, and the List ha like two elements by now!

I populate webViews on the getView() method of my CustomAdapter, this way:

holder.webDesc = (WebView) convertView.findViewById(R.id.hos_webView_Desc);
holder.webDesc.loadData(element.description, "text/html", "utf-8");

and the content on element.description is

<div style='text-align:justify;' bgcolor='#333333'>
<font color="#ff7f7f" size = 2>ABC </font>
<font color="#aaff7f" size = 2>DEFG</font>
</div>

end the WebView is declared in this way on .xml

<WebView
    android:id="@+id/hos_textView_why"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="@color/redS50B100"
    android:layout_marginLeft="@dimen/activity_horizontal_margin"
    android:layout_marginRight="@dimen/activity_horizontal_margin"
    android:layout_marginBottom="8dp"
/>

So I thought: am I populating wrong the WebView? If not, how can I speed up its load? Or, more drastically, there is an alternative to WebView which permits multi color managment and justification?

You can use Spannables for color, but justification is not available in the core SDK. — MLProgrammer-CiM, Sep 09 '14 at 13:55
I did not know Spannable, they are a good replacement! A pity I cannot justify text, but I think I can go with them. Thanks! — Simone Chelo, Sep 09 '14 at 14:24

Try to add following to your Manifest.xml

android:hardwareAccelerated="true"

and this to your CustomAdapter:

holder.webDesc.setLayerType(View.LAYER_TYPE_HARDWARE, null);

and you can try to add `holder.webDesc.setLayerType(View.LAYER_TYPE_HARDWARE, null);` – Metehan Sep 09 '14 at 14:05
