    Are you building this from XML or programmatically?

    I would make it with an XML file then when the Activity runs change the property. Be sure to use setContentView(R.layout.main); before you try to get the TextView with findViewById(...).

    Call .setVisibility(View.GONE); on the TextView to hide it.

    Call .setVisibility(View.VISIBLE); to on the TextView to show it.

    I have an example that does something like this. You can see the code here: https://github.com/ethankhall/Morse-Messenger/blob/master/src/com/kopysoft/MorseMessenger/Translate.java
