I need to use Theme.AppCompat.Light.NoActionBar, but Theme.AppCompat is not found in Android Studio

I added implementation ‘com.android.support:appcompat-v7:28.0.0’ to gradle, but the problem still the same

dependencies in gradle:

    add this library

    implementation ‘androidx.appcompat:appcompat:1.6.1’

    make sure latest should implement it will solve the problem.
    and also comment the old library

    implementation ‘com.android.support:appcompat-v7:28.0.0’

    the problem i think you write in your file theme.xml wrong way.
    in the "parent" of style.

    a common error when you new in android it is write like this:

    <?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.ShoppingList" parent="theme.AppCompat.Light.NoActionBar" />
</resources>

    or like this:

    <?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.ShoppingList" parent="android:Theme.AppCompat.Light.NoActionBar" />
</resources>

    The right way to write parent theme make sure you have like this:

    <?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.ShoppingList" parent="Theme.AppCompat.Light.NoActionBar" />
</resources>

    the parent theme starts with a capital letter "Theme"
