Question & Answer :
I person the pursuing TextView outlined:

<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:matter="@drawstring/txtCredits" android:autoLink="net" android:id="@+id/infoTxtCredits" android:layout_centerInParent="actual" android:linksClickable="actual"/>

wherever @drawstring/txtCredits is a drawstring assets that accommodates <a href="any tract">Nexus matter</a>.

Android is highlighting the hyperlinks successful the TextView, however they bash not react to clicks. What americium I doing incorrect? Bash I person to fit an onClickListener for the TextView successful my act for thing arsenic elemental arsenic this?

It seems to be similar it has to bash with the manner I specify my drawstring assets.

This does not activity:

<drawstring sanction="txtCredits"><a href="http://www.google.com">Google</a></drawstring>

However this does:

<drawstring sanction="txtCredits">www.google.com</drawstring>

Which is a bummer due to the fact that I would overmuch instead entertainment a matter nexus than entertainment the afloat URL.

Buried successful the API demos, I recovered the resolution to my job:

Record Nexus.java:

// text2 has hyperlinks specified by placing <a> tags successful the drawstring // assets. By default these hyperlinks volition look however not // react to person enter. To brand them progressive, you demand to // call setMovementMethod() connected the TextView entity. TextView t2 = (TextView) findViewById(R.id.text2); t2.setMovementMethod(LinkMovementMethod.getInstance());

I eliminated about of the attributes connected my TextView to lucifer what was successful the demo.

<TextView android:id="@+id/text2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:matter="@drawstring/txtCredits"/>

That solved it. It is beautiful hard to uncover and hole.
