android - 三星更新后的错误 |单人游戏 |将 viewport.height 检测为设备宽度

Question

更新

此问题也已在以下内容中讨论:https://github.com/mono/MonoGame/issues/2492

问题是如果应用程序只允许在横向运行，而不是当你使用纵向或两者都运行时。

有一个用 monogame 编码的安卓游戏，我有一个 GraphicsDeviceManager 设置为 FullScreen=true。

我使用 GraphicsDevice.Viewport.Height 和 GraphicsDevice.Viewport.Width 来确定设备的分辨率。在我获得三星更新并且不得不关闭 FastDev 之前，这一直非常有效。神秘的大问题:

当我用 pc 调试时，viewport 的高度和宽度设置正确。但是，当我在 1-2 次后拔下并播放应用程序时，viewport.Height 变为设备宽度，而 viewport.Width 变为设备高度，这完全使游戏无法玩。

很难找到解决方案，因为当我调试并将电缆从 PC 连接到设备时，这种情况从未发生过。

有人知道它是什么吗？

我现在可以确认这是因为三星更新

我制作了世界上最简单的 android 应用程序来测试它，只得到了一个带有名为“bg”的背景图像的大型机和一个打印出 viewport.Width 和 viewport.Height 的 spritefront。

代码如下:

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;

namespace TestRes
{
    /// <summary>
    /// This is the main type for your game
    /// </summary>
    public class Game1 : Microsoft.Xna.Framework.Game
    {
        GraphicsDeviceManager graphics;
        SpriteBatch spriteBatch;
        SpriteFont font;
        Rectangle _mainFrame;
        Texture2D _background;
        string text;

        public Game1()
        {
           graphics = new GraphicsDeviceManager(this);

            Content.RootDirectory = "Content";

            graphics.IsFullScreen = true;
            //graphics.PreferredBackBufferWidth = 800;
           // graphics.PreferredBackBufferHeight = 480;
            graphics.SupportedOrientations = DisplayOrientation.LandscapeLeft;
        }

        /// <summary>
        /// Allows the game to perform any initialization it needs to before starting             
       /// This is where it can query for any required services and load any non-
    /// related content.  Calling base.Initialize will enumerate through any components
    /// and initialize them as well.
    /// </summary>
        protected override void Initialize()
        {
            // TODO: Add your initialization logic here

            base.Initialize();
           text = "";
       }

    /// <summary>
    /// LoadContent will be called once per game and is the place to load
    /// all of your content.
    /// </summary>
        protected override void LoadContent()
        {
        // Create a new SpriteBatch, which can be used to draw textures.
            spriteBatch = new SpriteBatch(GraphicsDevice);
            _background = Content.Load<Texture2D>("Bilder/bg");
           _mainFrame = new Rectangle(0, 0, this.GraphicsDevice.Viewport.Width,     this.GraphicsDevice.Viewport.Height);
        // TODO: use this.Content to load your game content here
        font = Content.Load<SpriteFont>("spriteFont1");
    }

    /// <summary>
    /// Allows the game to run logic such as updating the world,
    /// checking for collisions, gathering input, and playing audio.
    /// </summary>
    /// <param name="gameTime">Provides a snapshot of timing values.</param>
        protected override void Update(GameTime gameTime)
        {
            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
             {
                 Exit();
             }
           text = "ScreenWidth: " + this.GraphicsDevice.Viewport.Width + ", screenheight: " + this.GraphicsDevice.Viewport.Height;
        // TODO: Add your update logic here

            base.Update(gameTime);
    }

    /// <summary>
    /// This is called when the game should draw itself.
    /// </summary>
    /// <param name="gameTime">Provides a snapshot of timing values.</param>
        protected override void Draw(GameTime gameTime)
        {
           graphics.GraphicsDevice.Clear(Color.CornflowerBlue);

           spriteBatch.Begin();
           spriteBatch.Draw(_background, _mainFrame, Color.White);
           spriteBatch.DrawString(font, text, new Vector2(16, 1000), Color.White);
           spriteBatch.End();

           base.Draw(gameTime);
       }
    }
}

从 VS 部署时一切正常，viewport.width 是实际设备宽度，viewport.height 是实际设备高度。但是当尝试从 Samsung Galaxy S4 active 部署它时(有时您需要尝试 2-3 次)然后突然 Viewport.Height 是设备宽度，反之亦然，这使得背景图片只覆盖了一点屏幕。

检查到 3.6 版本，bug 已修复。
