如何在没有核心项目的情况下使用 libgdx

Question

我一直在尝试在一个新的 eclipse 项目中在没有核心项目的情况下实现 libgdx，但我不断得到：

该方法初始化(应用程序侦听器， AndroidApplicationConfiguration(的类型为AndroidApplication is not 适用于参数(安卓应用程序， 安卓应用配置(

目前我使用的代码非常简单：

package com.debels.androidapplication;
import com.badlogic.gdx.backends.android.AndroidApplication;
import com.badlogic.gdx.backends.android.AndroidApplicationConfiguration;
import android.os.Bundle;
public class MainActivity extends AndroidApplication{
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration();
        cfg.useGL20 = false;
        initialize(new AndroidApplication(), cfg);
    }
}

和

package com.debels.androidapplication;
import com.badlogic.gdx.Game;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.FPSLogger;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.graphics.Texture;
//import com.badlogic.gdx.graphics.Texture.TextureFilter;
import com.badlogic.gdx.graphics.g2d.Sprite;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
//import com.badlogic.gdx.graphics.g2d.TextureRegion;
import com.debels.androidapplication.screens.MainMenuScreen;
public class AndroidApplication extends Game{
    private OrthographicCamera camera;
    private SpriteBatch batch;
    private Texture texture;
    private Sprite sprite;
    private FPSLogger fps;
    @Override
    public void create(){
        float w = Gdx.graphics.getWidth();
        float h = Gdx.graphics.getHeight();
        camera = new OrthographicCamera(1, h/w);
        batch = new SpriteBatch();
        //texture = new Texture(Gdx.files.internal("data/libgdx.png"));
        //texture.setFilter(TextureFilter.Linear, TextureFilter.Linear);
        //TextureRegion region = new TextureRegion(texture, 0, 0, 512, 275);
        /*sprite = new Sprite(region);
        sprite.setSize(0.9f, 0.9f * sprite.getHeight() / sprite.getWidth());
        sprite.setOrigin(sprite.getWidth()/2, sprite.getHeight()/2);
        sprite.setPosition(-sprite.getWidth()/2, -sprite.getHeight()/2);*/
        setScreen(new MainMenuScreen(this));
        fps = new FPSLogger();
    }
    @Override
    public void dispose() {
        super.dispose();
    }
    @Override
    public void render() {
        super.render();
        /*fps.log();
        Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
        batch.setProjectionMatrix(camera.combined);
        batch.begin();
        sprite.draw(batch);
        batch.end();*/
    }
    @Override
    public void resize(int width, int height) {
        super.resize(width, height);
    }
    @Override
    public void pause() {
        super.pause();
    }
    @Override
    public void resume() {
        super.resume();
    }
}

这是因为您要将(gdx(AndroidApplication实例发送到ini而不是(gdx(AndroidApplicationListener(这是扩展游戏或实现ApplicationListener的任何类(。

你会感到困惑，因为你把那个类命名为AndroidApplication......

更改此设置：

initialize(new AndroidApplication(), cfg);

对此：

initialize(new com.debels.androidapplication.AndroidApplication(), cfg);

或者更好的是，更改该类的名称。另外不要忘记将 gdx.jar 复制到 android 项目 libs 文件夹中。
