Java Can'；在onActivityResult中加载纹理

这是核心项目：

public class GameClass extends Game {

    public CustomScreen customScreen;
    public CustomScreen currentScreen;

    public CustomInterface handler;

    public static int screenWidth;
    public static int screenHeight;

    public GameClass(CustomInterface handler) {
        this.handler = handler;
    }

    @Override
    public void create () {
        screenWidth = Gdx.graphics.getWidth();
        screenHeight = Gdx.graphics.getHeight();
        customScreen = new CustomScreen();
        currentScreen = customScreen;
        setScreen(currentScreen);
        handler.PickFile();
    }

    public void onPickFile(String filePath) {
        currentScreen.onPickFile(filePath);
    }
}

public class CustomObject {

    public Texture texture;

    public CustomObject() {
        this.texture = new Texture(Gdx.files.internal("badlogic.jpg"));
    }

    public void Display(SpriteBatch batcher) {
        batcher.draw(texture, 0, 0, 500, 500);
    }
}

public interface CustomInterface {
    public void PickFile();
}

public class CustomScreen implements Screen {

    Texture texture = new Texture(Gdx.files.internal("badlogic.jpg"));

    SpriteBatch batcher;
    OrthographicCamera cam;
    CustomObject obj2;

    public CustomScreen() {
        cam = new OrthographicCamera();
        cam.setToOrtho(true, GameClass.screenWidth, GameClass.screenHeight);
        batcher = new SpriteBatch();
        batcher.setProjectionMatrix(cam.combined);
    }

    public void onPickFile(String filePath) {
        obj2 = new CustomObject();
    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL30.GL_COLOR_BUFFER_BIT);

        batcher.begin();
        if (obj2 != null)
            obj2.Display(batcher);
        batcher.end();
    }
}

public class AndroidLauncher extends AndroidApplication implements CustomInterface {

    GameClass game;

    @Override
    protected void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
        game = new GameClass(this);
        initialize(game, config);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        game.onPickFile("");
    }

    public void PickFile() {
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.addCategory(Intent.CATEGORY_OPENABLE);
        intent.setType("image/*");
        startActivityForResult(intent, 1);
    }
}

这就是Android项目：

public class GameClass extends Game {

    public CustomScreen customScreen;
    public CustomScreen currentScreen;

    public CustomInterface handler;

    public static int screenWidth;
    public static int screenHeight;

    public GameClass(CustomInterface handler) {
        this.handler = handler;
    }

    @Override
    public void create () {
        screenWidth = Gdx.graphics.getWidth();
        screenHeight = Gdx.graphics.getHeight();
        customScreen = new CustomScreen();
        currentScreen = customScreen;
        setScreen(currentScreen);
        handler.PickFile();
    }

    public void onPickFile(String filePath) {
        currentScreen.onPickFile(filePath);
    }
}

public class CustomObject {

    public Texture texture;

    public CustomObject() {
        this.texture = new Texture(Gdx.files.internal("badlogic.jpg"));
    }

    public void Display(SpriteBatch batcher) {
        batcher.draw(texture, 0, 0, 500, 500);
    }
}

public interface CustomInterface {
    public void PickFile();
}

public class CustomScreen implements Screen {

    Texture texture = new Texture(Gdx.files.internal("badlogic.jpg"));

    SpriteBatch batcher;
    OrthographicCamera cam;
    CustomObject obj2;

    public CustomScreen() {
        cam = new OrthographicCamera();
        cam.setToOrtho(true, GameClass.screenWidth, GameClass.screenHeight);
        batcher = new SpriteBatch();
        batcher.setProjectionMatrix(cam.combined);
    }

    public void onPickFile(String filePath) {
        obj2 = new CustomObject();
    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL30.GL_COLOR_BUFFER_BIT);

        batcher.begin();
        if (obj2 != null)
            obj2.Display(batcher);
        batcher.end();
    }
}

public class AndroidLauncher extends AndroidApplication implements CustomInterface {

    GameClass game;

    @Override
    protected void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
        game = new GameClass(this);
        initialize(game, config);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        game.onPickFile("");
    }

    public void PickFile() {
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.addCategory(Intent.CATEGORY_OPENABLE);
        intent.setType("image/*");
        startActivityForResult(intent, 1);
    }
}

调用CustomScreen类中的render函数时，在我从Android库中拾取一张图片后，它显示的不是我期望的badlogic.jpg纹理，而是黑色纹理

这是它显示的内容：

这就是它应该显示的内容：

（我知道Android项目中的部分代码是无用的，我基本上可以在核心项目中加载badlogic.jpg纹理，但最终的目的是加载从Android库中拾取的纹理，但正如您所看到的，我甚至还不能在资产文件夹中加载纹理）

我已经试着解决这个问题好几个月了，但我仍然不知道怎么做，请帮帮我

在渲染函数中，确实如此。我会把它显示的屏幕截图。它调用obj2.Display（batcher），它应该显示obj2.texture（aka badlogic.jpg）。一个是我看到的，另一个是我应该看到的像这样

Gdx.app.postRunnable（new Runnable（）{@Override public void run（）{obj2=new CustomObject（）；}}）只是猜测OpenGL不喜欢在其他线程上加载纹理。（在本例中是Android UI线程而不是OpenGL线程）它可以工作！非常感谢你！
