Android 启动屏幕在从一个页面导航到另一个页面之间可见xamarin表单

我正在从事Xamarin forms PCL项目，我想在我的项目中实现一个启动屏幕。下面是Xamarin.android部分的示例

当我从一个页面导航到另一个页面时，在页面之间可以看到启动屏幕。以上问题的任何解决方案

splash_screen.xml

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="fill_horizontal|fill_vertical"
android:src="@drawable/SplashScreen" 

<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-->
