Java Android的视口问题

Java Android的视口问题,java,android,eclipse,libgdx,Java,Android,Eclipse,Libgdx,当我在桌面上运行游戏时,效果很好,但当我在android设备上运行游戏时,图像看起来被切成了一半,当我使用“播放”按钮时,游戏关闭,有人能帮我吗?多谢各位 public class GameScreen extends AbstractScreen { private Viewport viewport; private Camera camera; private SpriteBatch batch; private Texture texture;

如果(ball.getBordes().x首先,使用正交照相机

camera.position.set(800/2f,480/2f,0);
viewport=new FitViewport(800,480,camera);
现在0,0位于屏幕的左下角

在开始批处理之前,不要忘记设置投影矩阵

batch.setProjectionMatrix(camera.combined);
