Android remove action bar

Question

I'm trying to disable the action bar for some of my activities, but no matter what I try I can't seem to remove it.

In my styles.xml I have:

<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>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

And in my manifest.xml I have:

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".NewActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
        </activity>
</application>

My activity layout file:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_new"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>

My app_bar_new layout file:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context="net.binarysea.sensorload.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </android.support.design.widget.AppBarLayout>

    <include layout="@layout/content_new" />

</android.support.design.widget.CoordinatorLayout>

I want the action bar to display on activities apart from one (NewActivity). I use intents to call up NewActivity, at which point I thought it would load up the AppTheme.NoActionBar style, but the bar still appears on the screen

I'm using the navigation drawer activity in android studio if that makes a difference

EDIT: I've tried all the suggesting adding Adding Theme.AppCompat.Light.NoActionBar, but that only makes my action bar white and doesn't actually remove it. I tested this in a new android studio project, created a navigation drawer activity, and add the theme setting to my styles.xml. I still get the same problem

Answer 1

Try this...

Just add parent tag for your style.

Styles.xml

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

AndroidManifest.xml

 .......

  <application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

     <activity
        android:name=".NewActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar">
      </activity>
   </application>
    ........

Try and drop the following into your manifest android:theme="@style/Theme.AppCompat.Light.NoActionBar"
