Android Activity without ActionBar

I have different Activities in my App and in all of them I do not want the Action Bar. I cannot find how to disable it. I have tried to find an attribute to apply it to the main_activity.xml but so far I did not find anything. Can somebody help me please?

Solution 1:

Haha, I have been stuck at that point a while ago as well, so I am glad I can help you out with a solution, that worked for me at least :)

What you want to do is define a new style within values/styles.xml so it looks like this

<resources>
    <style name = "AppTheme" parent = "android:Theme.Holo.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

    <style name = "NoActionBar" parent = "@android:style/Theme.Holo.Light">
        <item name = "android:windowActionBar">false</item>
        <item name = "android:windowNoTitle">true</item>
    </style>

</resources>

Only the NoActionBar style is intresting for you. At last you have to set is as your application's theme in the AndroidManifest.xml so it looks like this

<application
    android:allowBackup = "true"
    android:icon = "@drawable/ic_launcher"
    android:label = "@string/app_name"
    android:theme = "@style/NoActionBar"   <!--This is the important line-->
    >
    <activity
    [...]

I hope this helps, if not, let me know.

Solution 2:

There are multiple ways of doing this.

1) Change the theme in Android Manifest

Below the Application element, you will find theme tag. Replace it with this one -

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

If you are using AppCompat, use @android:style/Theme.AppCompat.NoActionBar.

This will set the theme for all activities. If you don't need the action bar in a specific acitivity, then set the theme in the activity container, ie

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

You may also set android:theme="@android:style/Theme.NoTitleBar" theme in the styles and use it later on.

2) Create a Custom Theme

Add this in res/values/styles.xml

<style name="NoActionBar" parent="@android:style/Theme.Holo.Light">
     <item name="windowActionBar">false</item>
     <item name="android:windowNoTitle">true</item>
</style>

and then set it as your activity's theme in Manifest:

<activity android:theme="@style/NoActionBar" ... />

3) Dynamically Remove the Action Bar

Put this code in the onCreate method before setting content view -

getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
getActionBar().hide();

If you are using the support library use getSupportActionBar().
