Answer 1

If I understand you right, you want to clear your LinearLayout? so put in your second line after findView... resultTrips.removeAllViews();

The better aproach would be only adding one TextView to your Linearlayout and edit this one.

Answer 2

You can use resultTips.removeAllViews(); to remove the resultTips layout or resultTips.removeView(dummy); to remove the TextView. Hope it helps.
