Question

这是我的代码：包com.mygdx.game;

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Input;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

public class MyGdxGame extends ApplicationAdapter {
   SpriteBatch batch;
   Texture img;

   @Override
   public void create () {
        Gdx.input.setCatchBackKey(true);
      batch = new SpriteBatch();
      img = new Texture("badlogic.jpg");

   }

   @Override
   public void render () {
        if (Gdx.input.isKeyJustPressed(Input.Keys.BACK)) {
            Gdx.app.log("Debug", "Back pressed!");
            Gdx.app.exit();
        }
      Gdx.gl.glClearColor(1, 0, 0, 1);
      Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
      batch.begin();
      batch.draw(img, 0, 0);
      batch.end();
   }
}

我不知道为什么代码没有按预期工作，当我用“isKeyPressed”替换“isKeyJustPressed”时它完美无缺。或者用Keys.ESCAPE（在桌面模块上运行）替换Keys.Back。

有什么想法吗？感谢

Keys.BACK可能不是你想要的。尝试Keys.BACKSPACE

Gdx.input.isKeyJustPressed（Input.Keys.BACK）不起作用
