在Android上拉伸游戏画面以跨设备统一分辨率

古之立大事者，不惟有超世之才，亦必有坚忍不拔之志。这篇文章主要讲述在Android上拉伸游戏画面以跨设备统一分辨率相关的知识，希望能为你提供帮助。
目前，我的游戏使用以下代码以正确的宽高比填充屏幕：
在Initialise()我有：

protected override void Initialize() { graphics.IsFullScreen = true; screen_width = graphics.GraphicsDevice.Viewport.Width; screen_height = graphics.GraphicsDevice.Viewport.Height; graphics.SupportedOrientations = DisplayOrientation.LandscapeLeft | DisplayOrientation.LandscapeRight; graphics.ApplyChanges(); base.Initialize(); }

在LoadContent()我有：

protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); float screenscale = screen_width / screen_height; SpriteScale = Matrix.CreateScale(screenscale, screenscale, 1f); //load textures here// }

在Draw()我有：

protected override void Draw(GameTime gameTime) { spriteBatch.Begin(SpriteSortMode.Immediate, null, null, null, null, null, SpriteScale); //Draw sprites here//spriteBatch.End(); base.Draw(gameTime); }

但是，使用此代码会根据设备宽度显示不同数量的游戏屏幕。
如何根据设备显示和缩放相同数量的游戏画面（如下图所示）？

在活动类我有：

using android.App; using Android.Content.PM; using Android.OS; using Android.Views; namespace android_game3 { [Activity(Label = "android_game3" , MainLauncher = true , Icon = "@drawable/icon" , Theme = "@style/Theme.Splash" , AlwaysRetainTaskState = true , LaunchMode = Android.Content.PM.LaunchMode.SingleInstance , ScreenOrientation = ScreenOrientation.UserLandscape , ConfigurationChanges = ConfigChanges.Orientation | ConfigChanges.Keyboard | ConfigChanges.KeyboardHidden | ConfigChanges.ScreenSize)] public class Activity1 : Microsoft.Xna.Framework.AndroidGameActivity { protected override void OnCreate(Bundle bundle) { base.OnCreate(bundle); var g = new Game1(); SetContentView((View)g.Services.GetService(typeof(View))); g.Run(); //Hide action bar View vw = (View)g.Services.GetService(typeof(View)); vw.SystemUiVisibility = (StatusBarVisibility)SystemUiFlags.HideNavigation | (StatusBarVisibility)SystemUiFlags.ImmersiveSticky; vw.SetOnSystemUiVisibilityChangeListener(new MyUiVisibilityChangeListener(vw)); }//Hide action bar private class MyUiVisibilityChangeListener : java.Lang.Object, View.IOnSystemUiVisibilityChangeListener { View targetView; public MyUiVisibilityChangeListener(View v) { targetView = v; } public void OnSystemUiVisibilityChange(StatusBarVisibility v) { if (targetView.SystemUiVisibility != ((StatusBarVisibility)SystemUiFlags.HideNavigation | (StatusBarVisibility)SystemUiFlags.Immersive)) { targetView.SystemUiVisibility = (StatusBarVisibility)SystemUiFlags.HideNavigation | (StatusBarVisibility)SystemUiFlags.ImmersiveSticky; } } } } }

答案我检查了我的旧android项目，我用过：
