如何在Xamarin中创建适合所有屏幕大小的闪屏

protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);

    // 设置闪屏图片为启动屏幕
    SetContentView(Resource.Layout.SplashScreen);

    // 其他初始化代码...
}

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/splash_screen"
        android:scaleType="centerCrop" />

</RelativeLayout>

protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);

    // 设置闪屏图片为启动屏幕
    SetContentView(Resource.Layout.SplashScreen);

    // 设置闪屏持续时间为2秒
    Handler handler = new Handler();
    handler.PostDelayed(() =>
    {
        // 跳转到主界面或登录界面
        StartActivity(new Intent(this, typeof(MainActivity)));
        Finish();
    }, 2000);

    // 其他初始化代码...
}
