It because activity recreate after screen rotate. Simple fix is adding android:id to your TextView at xml.

Android automatically destroys the activity and recreates it adapting it to the new orientation of the screen when the device is rotated.

Avoidance of the activity destruction and recreation is inevitable but what you can do is force the activity to maintain a fixed orientation. or save what you need to in the saveInstanceState(Bundle) method of the activity and later retireve it from the same bundle passed on to it via the onCreate(Bundle); or restoreInstanceState(); also ingoring onConfigChange() is an option but is highly discouraged. – Niraj Adhikari Nov 06 '13 at 15:12

@Samuel Could be because his is the only correct answer whilst the ones which have been downvoted are simply wrong? – Simon Nov 06 '13 at 19:14

If you dont want activity to recreate on orientation change you can add this line

android:configChanges="orientation|keyboardHidden"

in Android manifet for that Activity.. for eg:-

<activity android:name=".MyActivity"
          android:configChanges="orientation|keyboardHidden"
          android:label="@string/app_name">
