Implement splash screen. how do I specify the image size? - xamarin.forms

Question

I do splash screen, but the problem is that I do not know where to add
styles. how do I specify the image size ? How do I add text ?
[Activity(Label = "SplashActivity", Theme = "#style/Theme.Splash", MainLauncher = true)]
public class SplashScreen : Activity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
StartActivity(typeof(MainActivity));
Finish();
OverridePendingTransition(0, 0);
}
}
`
In drawable folder splash_screen.xml:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<color android:color="#color/splash_background"/>
</item>
<item>
<bitmap
android:src="#drawable/splash_logo"
android:tileMode="disabled"
android:gravity="center"
/>
</item>
</layer-list>
Folder values, style.xml:
<style name="Theme.Splash" parent ="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowBackground">#drawable/splash_screen</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowActionBar">true</item>
</style>

Answer 1

I think you have two options.
1- create an image and visualize it (as in your sample)
2- create an activity layout, so you can add image, text... what you want
You can find some info in the official documentation: Xamarin.Forms SplashScreen
and here you can find the Android Sample: Xamarin.Android SplashScreen
In this sample, you have a style with a drawable:
<resources>
<style name="MyTheme.Base" parent="Theme.AppCompat.Light">
</style>
<style name="MyTheme" parent="MyTheme.Base">
</style>
<style name="MyTheme.Splash" parent ="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowBackground">#drawable/splash_screen</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowActionBar">true</item>
</style>
</resources>
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<color android:color="#color/splash_background"/>
</item>
<item>
<bitmap
android:src="#drawable/splash_logo"
android:tileMode="disabled"
android:gravity="center"/>
</item>
</layer-list>
but you can use a layout, in the same way it is used for MainActivity
