Images in android textview using fromHtml method doesn't show up

Question

I'm trying to display images in my help file using the Html.fromHtml method.

This is my java code

            TextView tv = (TextView)findViewById(R.id.text);
        tv.setText(Html.fromHtml(getString(R.string.help), new Html.ImageGetter() {
            @Override
             public Drawable getDrawable(String source) {
                    int id;

                    if (source.equals("top_scrollers.png")) {
                        id = R.drawable.top_scrollers;
                    }
                    else if (source.equals("prices.png")) {
                        id = R.drawable.prices;
                    }
                    else if (source.equals("percentage.png")) {
                        id = R.drawable.percentage;
                    }
                    else if (source.equals("mplus.png")) {
                        id = R.drawable.mplus;
                    }
                    else {
                        return null;
                    }

                    Drawable d = getResources().getDrawable(id);
                    d.setBounds(0,0,d.getIntrinsicWidth(),d.getIntrinsicHeight());
                    return d;
                }
        }, null));

And this is my xml

<string name="help">
<![CDATA[
<h1>Help</h1>
<p>
<h3>Getting stone price</h3>
<img src="top_scrollers.png"/>
</p>
]]>
</string>

As you can see i'm placing the images in the cdata text, and I have created a method to create drawables from them, but it is just isn't displayable. Any suggestions?

Answer 1

You can use WebView instead TextView for it. Try this solution:

1) Put your top_scrollers.png in assets folder

2) Create your_html.html in raw folder with content:

<h1>Help</h1>
<p>
<h3>Getting stone price</h3>
<img src="file:///android_asset/top_scrollers.png"/>
</p> 

3) For read this raw file as string you can read this Android read text raw resource file

4) After that you can load this text in webView:

webView.loadDataWithBaseURL("", your_raw_string, "text/html", "utf-8", "");
