Question

I am retrieving some HTML from my site and putting it into a TextView. This HTML might contain anchor tags that point to web pages, emails, etc. I am trying to make these links click-able in a way such that when the user clicks on it, the default browser opens the web page. I am doing this by following the instructions on this answer- How do I make links in a TextView clickable? and a couple of other sources online.

So my code is something like this :

TextView para=new TextView(getApplicationContext());    
LayoutParams lpfortext=new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
lpfortext.setMargins(10, 10, 10, 10);
para.setText(Html.fromHtml(e.html()));
para.setMovementMethod(LinkMovementMethod.getInstance());
para.setLinksClickable(true); //error exists on removing this
para.setAutoLinkMask(Linkify.ALL);  //error exists on removing this
para.setLayoutParams(lpfortext);

But when I actually click on a link in the app (on an ICS phone, haven’t tested on an emulator yet), I get the following error (a snapshot of the stack trace, full text at the end) :

11-18 13:17:51.503: E/AndroidRuntime(6010): android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity  context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

11-18 13:17:51.503: E/AndroidRuntime(6010):     at android.text.method.LinkMovementMethod.onTouchEvent(LinkMovementMethod.java:212)

Any ideas what could be causing the error and how to fix it?

Answer 1

It seems that you initialize the para TextView object with a non-Activity context , which require to set Intent.FLAG_ACTIVITY_NEW_TASK on the Intent that starts the Activity.

this will solve the problem

TextView para = new TextView(this); this refer to Activity context
