APPCOMPAT
당신이 버튼에서 상속해야하는 동시에 일반 버튼을 APPCOMPAT을 사용하고 CustomRenderer
을 등록 할 경우
. 당신은 당신이 두 가지

당신의 MainActivity
비 APPCOMPAT 스타일에서 상속해야합니다 global::Xamarin.Forms.Platform.Android.FormsApplicationActivity
보통 resources/values/styles.xml
에서 당신의 스타일에서 지금 상속해야합니다 like android:Theme.Material
<resources>
<!-- inherit from the material theme -->
<style name="AppTheme" parent="android:Theme.Material">
<!-- Main theme colors -->
<!-- your app branding color for the app bar -->
<item name="android:colorPrimary">@color/primary</item>
<!-- darker variant for the status bar and contextual app bars -->
<item name="android:colorPrimaryDark">@color/primary_dark</item>
<!-- theme UI controls like checkboxes and text fields -->
<item name="android:colorAccent">@color/accent</item>
</style>
</resources>
