How to remove Title Bar from Activity extending ActionBarActivity or AppcompatActivity with Dialog Theme
I had same issue and needed to do something like following to resolve (note use of "windowNoTitle" instead of "android:windowNoTitle")
<style name="Theme.MyDialog" parent="@style/Theme.AppCompat.Light.Dialog"> <item name="windowActionBar">false</item> <item name="windowNoTitle">true</item></style>
Try
getSupportActionBar().hide() if you are using AppCompatActivity
And
getActionBar().hide() if your activity extends ActionBarActivity. Hope it helps.
You can hide the action bar at runtime by calling hide(). For example:
ActionBar actionBar = getSupportActionBar();actionBar.hide();
