android系統xamarin

Question

我試圖做一個抽屜式導航android的，但我得到這個錯誤創建抽屜式導航：

1.No resource found that matches the given name: attr 'colorPrimary'. 
2.No resource found that matches the given name: attr 'colorPrimaryDark'. 
3.No resource found that matches the given name 'Theme.AppCompat.Light.NoActionBar' 

，這裏是我的代碼

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <style name="Theme.DesignDemo" parent="Base.Theme.DesignDemo"></style> 
    <style name="Base.Theme.DesignDemo" parent="Theme.AppCompat.Light.NoActionBar"> 
    <item name="colorPrimary">#2196F3</item> 
    <item name="colorPrimaryDark">#1976D2</item> 
    </style> 
</resources> 

Answer 1

添加Xamarin支持V4和V7 AppCompat NuGet包到您的項目。

Answer 2

試試這個：

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <style name="Theme.DesignDemo" parent="Base.Theme.DesignDemo"></style> 
    <style name="Base.Theme.DesignDemo" parent="@android:style/Theme.AppCompat.Light.NoActionBar"> 
    <item name="android:colorPrimary">#2196F3</item> 
    <item name="android:colorPrimaryDark">#1976D2</item> 
    </style> 
</resources>
