Question

我的可绘制文件夹中有图像，并且将它们的大小调整为标准大小，然后将其放入每个文件夹中。但是，当我启动我的应用程序并运行MainActivity时，我的SplashScreen图像显示为拉伸状态，并且在屏幕上看起来很糟。我已经在线查看了答案，但没有任何效果。

我该怎么做才能使图像在初始屏幕上看起来正常。

这是我的MainActivity.cs

        [Activity(Label = "Peppy", Icon = "@mipmap/bicon", Theme = "@style/peppy", MainLauncher = true, NoHistory = true)]
        public class SplashActivity : Activity
    {
           protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);
            StartActivity(typeof(MainActivity));            
        }
    }

这就是我在style.xml中定义样式的方式

 <style name="peppy" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowBackground">@drawable/bluesplash</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:colorPrimaryDark">#1976D2</item>
  </style>

  <style name="Main Theme" parent="MainTheme.Base"></style>

我希望SplashScreen图像能够完美地适合屏幕。谢谢

我的drawables文件夹中有一个splashScreen.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item>
    <color android:color="@color/green_colour"/>
  </item>
  <item>
    <bitmap
        android:src="@drawable/splash_logo"
        android:tileMode="disabled"
        android:gravity="center"/>
  </item>
</layer-list>

使图像居中而不变形。

活动就是这样

using System.Threading.Tasks;
using Android.App;
using Android.Content;
using Android.OS;
using Android.Support.V7.App;
using Android.Util;
using App1.Droid;

namespace com.xamarin.sample.splashscreen
{
    [Activity(Theme = "@style/MyTheme.Splash", MainLauncher = true, NoHistory = true)]
    public class SplashActivity : AppCompatActivity
    {
        static readonly string TAG = "X:" + typeof(SplashActivity).Name;

        public override void OnCreate(Bundle savedInstanceState, PersistableBundle persistentState)
        {
            base.OnCreate(savedInstanceState, persistentState);
            Log.Debug(TAG, "SplashActivity.OnCreate");
        }

        // Launches the startup task
        protected override void OnResume()
        {
            base.OnResume();
            StartActivity(new Intent(Application.Context, typeof(MainActivity)));
        }

        // Prevent the back button from canceling the startup process
        public override void OnBackPressed() { }
    }
}

初始屏幕图像太拉伸
