App Theme Rendering Error

I am trying to hide the Action Bar with the latest Android Studio, but for some reason, it is not hiding. The android version that I have is newer than the one in the video, so it is not matching. Please help

If you are using the most up to date version of Android Studio you may need to remove some code from the activity_main.xml file in the layout folder. I had to remove the following code to get the Action Bar and email icon to be removed from mine

<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>

<android.support.design.widget.FloatingActionButton android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom|end" android:layout_margin="@dimen/fab_margin" android:src="@android:drawable/ic_dialog_email" />

Hope that helps :-)

Don't forget to check the MainActivity.java file for additional code that may need to be removed for the tool bars otherwise once you remove the code from the layout file the project will fail to compile.

Hi Arminder,

Have you modified the styles.xml file in the res/values folder?

Mine looks like this

<!-- styles.xml -->
<resources>

    <!-- Base application theme. -->
    <!-- TODO: Modify the line below to change the theme/remove ActionBar. -->
    <style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>

You'll want to change what it says after "parent=". Try going into that file, deleting everything up until "Theme.", then press CTRL+Space. You'll be provided with a list of available themes in a drop down, select the theme you want to use and go from there.

I encourage you to re-watch the video, some things may be different, but with a little problem solving and you'll find what you need. :-)

I hope that helps! But if it doesn't, please feel free to give a bit more information, we can help from there.
