Holoeverywhere : how to programmatically remove at runtime the action bar from an activity

Question

Which is the correct way to remove the action bar inside an activity ?

My activity extends org.holoeverywhere.app.Activity

I've a custom Application class that extends org.holoeverywhere.app.Application and at startup execs this static code :

ThemeManager.setDefaultTheme(ThemeManager.DARK);
ThemeManager.map(ThemeManager.DARK, R.style.Holo_Demo_Theme);
ThemeManager.map(ThemeManager.LIGHT,  R.style.Holo_Demo_Theme_Light);
ThemeManager.map(ThemeManager.MIXED, R.style.Holo_Demo_Theme_Light_DarkActionBar);
ThemeManager.map(ThemeManager.DARK | ThemeManager.FULLSCREEN,  R.style.Holo_Demo_Theme_Fullscreen);
ThemeManager.map(ThemeManager.LIGHT | ThemeManager.FULLSCREEN, R.style.Holo_Demo_Theme_Light_Fullscreen);
ThemeManager.map(ThemeManager.MIXED | ThemeManager.FULLSCREEN, R.style.Holo_Demo_Theme_Light_DarkActionBar_Fullscreen);

in my activity :

protected void onCreate(Bundle savedInstanceState) {

    ThemeManager.removeTheme(this);
    setTheme(ThemeManager.DARK | ThemeManager.FULLSCREEN);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

if I add requestWindowFeature(Window.FEATURE_NO_TITLE) in the code, on an android 4.1.1 -table- the bar is removed while on an handset -android 2.3.3- the bar is not removed.

Before introducing holoeverywhere everything worked fine with just requestWindowFeature(Window.FEATURE_NO_TITLE).

Which is the correct way to remove at runtime the actionbar in holoeverywhere ? (I want to do it at runtime because the user has the option to set a DARK or LIGHT layout, with a DARK default)

See flag ThemeManager.NO_ACTION_BAR. Or just call

getSupportActionBar().hide();

It also works with setTheme(ThemeManager.DARK | ThemeManager.NO_ACTION_BAR) ; I was using ThemeManager.FULLSCREEN instead of NO_ACTION_BAR – Maxj May 03 '13 at 09:34

You can do it programatically:

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;

public class ActivityName extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}

Or you can do it via your AndroidManifest.xml file:

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">
</activity>

I added some lines so that you can show it in fullscreen, as it seems that's what you want.

thanks for answer, but in your example you're not using the holoeverywhere library, but the "pure" android SDK... – Maxj May 02 '13 at 18:12
Oh sorry i oculdn't help you out. I replied with whatever i had knowledge of. – Chintan Soni May 02 '13 at 18:15
With pure SDK everything works. After I introduced the library I have this problem. I think it's a "stupid" problem, but the library has NO documentation at all ! – Maxj May 02 '13 at 18:18
Thanks for the answer... This prevented me from not supporting a few API versions :-) – m13r Aug 11 '14 at 21:40
When I do this, I am left with a blank white rectangle where the action bar would have been. What have I done wrong? Thanks. – AndyCr15 Aug 19 '17 at 09:05
