No resource found that mach the given name Theme.AppCompat.Light.NoActionBar

Question

I am adding some items in Styles.xml files. However, it is giving me an error.

Here is my code.

Answer 1

I can't remember if Theme.AppCompat.Light.NoActionBar exists in the first place.

You could do something like this instead:

<style name="MyTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">#2196F3</item>
    <item name="drawerArrowStyle">@style/MyDrawerArrowStyle</item>
    <item name="windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
</style>

Answer 2

Here are the steps to fix those issues;

1. Go to AndroidManifest.xml and add android:targetSdkVersion to 23 under uses-sdk tag.
2. Go to Project -> General and set Target framework to Android 6.0 (Marshmallow).
3. Go to Project -> Android Application -> set Target Android version to Android 6.0.

Android version 7.0 is not compiled in latest Xamarin Studio.Right now you can only compile Android project up to Android 6.0.

Answer 3

I found my solution by adding AppCompact v7 in the Package of my xamarin studio android project.

Answer 4

add component Support Library v7 AppCompat 

create values/styles and add
<?xml version="1.0" encoding="utf-8" ?>
<resources>

  <style name="MyTheme" parent="MyTheme.Base">
  </style>
  <style name="MyTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
    <!--If you are using revision 22.1 please use just windowNoTitle. Without android:-->
    <item name="windowNoTitle">true</item>
    <!--We will be using the toolbar so no need to show ActionBar-->
    <item name="windowActionBar">false</item>
    <!-- Set theme colors from http://www.google.com/design/spec/style/color.html#color-color-palette-->
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">#2196F3</item>
    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">#1976D2</item>
    <!-- colorAccent is used as the default value for colorControlActivated
         which is used to tint widgets -->
    <item name="colorAccent">#FF4081</item>
    <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight and colorSwitchThumbNormal. -->
  </style>
</resources>

add another folder values-v21
create styles.xml and add
<?xml version="1.0" encoding="utf-8" ?>
<resources>
  <!--
        Base application theme for API 21+. This theme replaces
        MyTheme from resources/values/styles.xml on API 21+ devices.
    -->
  <style name="MyTheme" parent="MyTheme.Base">
    <item name="android:windowContentTransitions">true</item>
    <item name="android:windowAllowEnterTransitionOverlap">true</item>
    <item name="android:windowAllowReturnTransitionOverlap">true</item>
    <item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
    <item name="android:windowSharedElementExitTransition">@android:transition/move</item>
  </style>
</resources>
