Android Activity without ActionBar

Question

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?

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.

If you want most of your activities to have an action bar you would probably inherit your base theme from the default one (this is automatically generated by Android Studio per default):

<!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

And then add a special theme for your bar-less activity:

<style name="AppTheme.NoTitle" parent="AppTheme">
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="actionBarTheme">@null</item>
    </style>

For me, setting actionBarTheme to @null was the solution.

Finally setup the activity in your manifest file:

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

You may also change inheritance from ActionBarActivity to Activity as written here.

UPDATE

A good solution is here:

@Override
protected void onCreate(Bundle savedInstanceState) {
    getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
    super.onCreate(savedInstanceState);
    getSupportActionBar().hide();
    setContentView(R.layout.activity_main);
}

Create an new Style with any name, in my case "Theme.Alert.NoActionBar"

<style name="Theme.Alert.NoActionBar" parent="Theme.AppCompat.Dialog">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
</style>

set its parent as "Theme.AppCompat.Dialog" like in the above code

open AndoridManifest.xml and customize the activity you want to show as Alert Dialog like this

    <activity
        android:excludeFromRecents="true"
        android:theme="@style/Theme.Alert.NoActionBar"
        android:name=".activities.UserLoginActivity" />

in my app i want show my user login activity as Alert Dialog, these are the codes i used. hope this works for you!!!
