找不到与给定名称'@ style / Theme.AppCompat.Light'相匹配的资源

Question

I'm facing few problems related to the theme.

In my manifest, I have the following code:

<application
    android:theme="@android:style/Theme.AppCompat.Light">

By using the above code, there is error No resource found that matches the given name '@style/Theme.AppCompat.Light' . Please refer to the image below that I've added the reference.

If I remove the theme setting, I'll receive runtime error saying that I must implement AppCompat theme. May I know which part has gone wrong?

Answer 1

As it seems you have referenced appcompat v7 library in your project, my initial guess is that you should use

<application
android:theme="@style/Theme.AppCompat.Light">

instead of

<application
android:theme="@android:style/Theme.AppCompat.Light">

Also ensure that both Android Support Library project and the Main Project have the same minSdkVerson and targetSdkVersion .

The key thing here i guess is that in the parent attribute android: .It prefixes built in themes (styles), while a value without this prefix references your own styles or the styles in any libraries you have linked to, in this case android-support-v7-appcompat .
