Sorry for my stupidy. I know it's simple but I'm a beginner. I've looked around and I couldn't find the answer.
styles.xml:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.Holo.Light.NoActionBar.Fullscreen">
<!-- Customize your theme here. -->
</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" />
</resources>
I'm trying to change the Application Theme, but I am always getting that error:
Rendering Problems
Missing Styles. Is the correct theme chosen for this layout?
Use the Theme combo box above the layout to choose a different layout or fix the theme style references.
Note: One or more layout are missing the layout_width or layout_height attributes. These are required in most layouts.
