Question

I have just started building android application. I have a php script outputting a URL.
The URL simply displays and is not clickable. I want to make the URL clickable so that if person clicks on the link the device browser opens the link. The link is stored in MySQL database which is fetched through php. I am using JSON encode.

For example
php Output: {“result”:[{“rid”:”3″,”rname”:”List of newly recruited students”,”rinfo”:”http://mydomain.com/out.php”}],”success”:1}

In android app i can see
http://mydomain.com/out.php
but the link is not clickable.

Java code that outputs the above php output in app

Answer 1

are you displaying the url in textbox, if so add autolink attribute in TextView

android:autoLink="all"

or call

textView.setAutoLinkMask(Linkify.ALL);

in code
