你可以用 HttpRequest 若要下载资源，请将它们保存到临时文件中，然后可以初始化 Texture , TextureRegion , Sprite 或者像你平时做的那样：

Net.HttpRequest request = new Net.HttpRequest(Net.HttpMethods.GET);
request.setUrl("https://lh3.googleusercontent.com/ogw/ADGmqu-Krm10pvcLx9MlffZK6f9DaQS3S8Afje3gRBk=s83-c-mo");

然后，在 handleHttpResponse 可以保存到临时文件的回调：

final FileHandle tmpFile = FileHandle.tempFile("texture");
tmpFile.write(httpResponse.getResultAsStream(), false);
Gdx.app.postRunnable(new Runnable() {
    @Override
    public void run () {
        texture = new Texture(tmpFile);
    }
});

请注意，您需要 postRunnable 返回到主线程，因为图形资源需要加载到opengl线程上。
应用程序加载资源的完整工作示例可能如下所示：

package com.bornander.sandbox;

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Net;
import com.badlogic.gdx.files.FileHandle;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

public class SandboxGame extends ApplicationAdapter {
    OrthographicCamera camera;
    SpriteBatch batch;
    Texture texture;

    @Override
    public void create () {
        float aspectRatio = (float)Gdx.graphics.getHeight()/(float)Gdx.graphics.getWidth();
        camera = new OrthographicCamera(800, 800 * aspectRatio);
        camera.position.set(camera.viewportWidth / 2.0f, camera.viewportHeight / 2.0f, 0.0f);
        batch = new SpriteBatch();

        Net.HttpRequest request = new Net.HttpRequest(Net.HttpMethods.GET);
        request.setUrl("https://lh3.googleusercontent.com/ogw/ADGmqu-Krm10pvcLx9MlffZK6f9DaQS3S8Afje3gRBk=s83-c-mo");
        Gdx.net.sendHttpRequest(request, new Net.HttpResponseListener() {
            @Override
            public void handleHttpResponse (Net.HttpResponse httpResponse) {
                final FileHandle tmpFile = FileHandle.tempFile("texture");
                tmpFile.write(httpResponse.getResultAsStream(), false);
                Gdx.app.postRunnable(new Runnable() {
                    @Override
                    public void run () {
                        texture = new Texture(tmpFile);
                    }
                });
            }

            @Override
            public void failed (Throwable t) { Gdx.app.error("yourtag", "failed to load", t); }

            @Override
            public void cancelled () { Gdx.app.log("yourtag", "load cancelled"); }
        });
    }

    @Override
    public void render () {
        Gdx.gl.glClearColor(0.6f, 0.6f, 1.0f, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        camera.update();
        batch.setProjectionMatrix(camera.combined);
        batch.begin();
        if (texture != null)
            batch.draw(texture, 0, 0);

        batch.end();
    }
}
