Xamarin.Forms<四> Android登录闪图

Xamarin.Forms Android闪图（适用于纯Android系统）
1、在Android.Resources.Drawable下添加好闪图的图片，命名为splashPicture。
2、在Android.Resources.Drawable新建一个splashscreen.xml的文件。

1 <?xml version="1.0" encoding="utf-8" ?>

2 <bitmap xmlns:android="http://schemas.android.com/apk/res/android"

3         android:src="@drawable/splashPicture"

4         android:gravity="center|fill"

5         android:layout_gravity="center"/>

3、在Android.Resources下新建一个Values的文件夹，在该文件夹下新建一个Styles.xml文件。

 1 <?xml version="1.0" encoding="utf-8" ?>

 2 <resources>

 3   <style name="Theme.Splash"

 4          parent="android:Theme.Holo.Light">

 5     <item name="android:windowBackground">@drawable/splashscreen</item>

 6     <item name="android:windowNoTitle">true</item>

 7     <item name="android:windowIsTranslucent">false</item>

 8     <item name="android:windowIsFloating">false</item>

4、在Android下新建一个SplashScreen的类

 1     [Activity(Label = "Test",MainLauncher = true, NoHistory = true, Theme = "@style/Theme.Splash",

 2     ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]

 3     public class SplashScreen : Activity

 4     {

 5         protected override void OnCreate(Bundle bundle)

 6         {

 7             base.OnCreate(bundle);

 8             var intent = new Intent(this, typeof(MainActivity));

 9             StartActivity(intent);

10             Finish();

11         }

12     }

5、将Android下的MainActivity.cs文件中的MainLauncher = true去掉。
