Open specific link in an other activity in Android

Question

I am working on an application where I need to parse some text which may have some links. When one of links contains a certain value, for example, www.abc.com and is tapped, I must open one of my activities.

I've tried the code in this accepted answer but but have been unable to make it work.

When I click on a link, I have nothing, I've tried to put some logging, for example:

public void onClick(View view) {
    Log.e("test",span.getURL());
}

But nothing is logged, it seems like I ever tapped on the link.

In my activity, I save data with an AsyncTask (it's ok, it works!) and in my onPostExecute method, I do:

protected void onPostExecute(Void result) {
   if(_flagOk){
        /* .... */
        setTextViewHTML(_contenu,datas); //where data is html code
    }
}

With the code of the link from above.
