Remove app title bar android

Question

I know this question has been asked million times but whichever method I use is not good for me.

If I use

android:theme="@android:style/Theme.NoTitleBar"  

in the manifest file, the whole theme of the app changes. If I put

requestWindowFeature(Window.FEATURE_NO_TITLE); 

in the onCreate activities, it shows up shortly when starting an app.

Btw I don't have any theme selected, just using standard android.

Answer 1

It is unclear what you mean by "whole theme of app changes". For API Level 11+ devices, you probably should be using @android:style/Theme.Holo.NoActionBar.

Answer 2

If you add the theme to the application, it applies to the whole app.

android:theme="@android:style/Theme.NoTitleBar" 

You have to add it to the activity declaration.

<activity     android:name=".YourActivity"     android:theme="@android:style/Theme.NoTitleBar"/>
