By the way - your layout is really bad, because there is a lot of nested layouts. It's better to move all this stuff into single RelativeLayout — Dmitry Zaytsev

First of all, there is no point in cast:

View v = (LinearLayout) inflater.inflate(R.layout.tab_frag2_layout, container, false);

Remove cast, or change type of v to LinearLayout.

It will be better if you'll provide your log cat with error message, but I supose that you're a getting ClassCastException here:

((LinearLayout) v).addView(tv);

Maybe your v isn't LinearLayout? If you're not sure, try this one instead:

((ViewGroup) v).addView(tv);

EDIT

When you're inflating layout the instance of View is created. One View can't have more than 1 parent, so when you're doing this:

.addView(tv);
.addView(tv);

OS thinks that you're trying to add another parent to tv (it's prohibited, so it's throws an Exception)

@nomee.tec use ListView instead. If for some reasons you can't, then do same operation in loop (but I strongly recommend you to use ListView).
