How to disable action bar permanently

Question

I can hide the action bar in honeycomb using this code:

getActionBar().hide();

But when the keyboard opens, and user copy-pastes anything, the action bar shows again. How can I disable the action bar permanently?

Make sure you create a new theme by changing the name of the default theme in the styles.xml file to:

 <style name="MyTheme" parent="android:Theme.Material.Light.NoActionBar">

and than change the theme from the drop-down under your main_activity.xml to whatever you called your theme.

I use the following code inside my onCreate function:

ActionBar actionBar = getSupportActionBar();
actionBar.hide();
