LibGDX从Core模块（MyGdxGame）中的android模块（AndroidLauncher）获取变量？

Question

所以我看过这篇关于它的文章，它解决了我猜的一些问题。链接：similar problem here

但是，我正在使用AdMob和Firebase集成，因此我使用AdView，AdRequest和MobileAds等。我在AndroidLauncher中使用这些并且工作正常，但在尝试实现名为AdsManager的界面并创建AdView类型的变量时，它可以解决它。我想这是因为我不在android模块中。那么当我进入核心模块（MyGdxGame）时，如何从AndroidLauncher获取“AdMob类型”变量？

示例：Android模块

的AdsManager

package com.game.mygame.monetization;

public interface AdsManager {
    void showAds(boolean show);
}

AndroidLauncher

public class AndroidLauncher extends AndroidApplication implements AdsManager {

private final String TAG = "AndroidLauncher";
private AdHandler adHandler; // Variable I want to reach from core module

static class AdHandler extends Handler {
    private final int ADS_SHOW = 1;
    private final int ADS_HIDE = 0;
    private AdView adBanner; // Variable I want to reach from core module

    @Override
    public void handleMessage(Message msg) {
        super.handleMessage(msg);

        switch (msg.what) {
            case ADS_SHOW:
                adBanner.setVisibility(View.VISIBLE);
                break;

            case ADS_HIDE:
                adBanner.setVisibility(View.GONE);
                break;
        }
    }
}

@Override
protected void onCreate (Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
    RelativeLayout layout = new RelativeLayout(this);
    View view = initializeForView(new MyGdxGame(this), config);
    layout.addView(view);

    implementAds();
    requestAds(layout);

    // Sets the background image
    setContentView(layout);
}

public void implementAds() {
    // Implement ads
    MobileAds.initialize(this, "");

    adHandler = new AdHandler();
    adHandler.adBanner = new AdView(this);
    adHandler.adBanner.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {
            super.onAdLoaded();
            Log.i(TAG, "Ad loaded ...");
        }
    });

    adHandler.adBanner.setAdSize(AdSize.SMART_BANNER);
    adHandler.adBanner.setAdUnitId("");

}

public void requestAds(RelativeLayout layout) {
    AdRequest.Builder builder = new AdRequest.Builder();
    builder.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);
    builder.addTestDevice("");

    RelativeLayout.LayoutParams adBannerParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    adBannerParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
    adBannerParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);

    layout.addView(adHandler.adBanner, adBannerParams);
    adHandler.adBanner.loadAd(builder.build());
}

@Override
public void showAds(boolean show) {
    adHandler.sendEmptyMessage(show ? adHandler.ADS_SHOW : adHandler.ADS_HIDE);
}

}

当试图创建一个名为AndroidAdsManager的类来实现AdsManager时，它无法解析私有的AdView变量，因为我不再在Android模块中。

核心模块

public class AndroidAdsManager implements AdsManager {
    private AdView adBanner; // Error: Android Studio doesn't find this type
    private AdHandler adHandler; // Also needs this in here, I guess, maybe not

    @Override
    public void showAds(boolean show) {
        adHandler.sendEmptyMessage(show ? adHandler.ADS_SHOW : adHandler.ADS_HIDE);
    }
}

长话短说：你不能 您好Kevvex，您无法从核心模块中的类访问AdView或AdHandler，您需要做的就是（如您提供的链接所示）在AndroidAdsManager类中实现所有逻辑实现您的AdsManager界面 关于这个问题的方法是，无论何时你想要使用Android模块中的类型进行某些操作，在AndroidAdsManager中都有一个方法，你需要在AdsManagerInterface中创建方法来调用它们： AndroidAdsManager

public class AndroidAdsManager implements AdsManager {
  private AdView adBanner;
  private AdHandler adHandler;

    @Override
    public void showAds(boolean show) {
        adHandler.sendEmptyMessage(show ? adHandler.ADS_SHOW : adHandler.ADS_HIDE);
    }
    @Override
    public void implementAds() {
        // Implement ads
        MobileAds.initialize(this, ""); // HERE YOU NEED TO GET THE CONTEXT

        adHandler = new AdHandler();
        adHandler.adBanner = new AdView(this);
        adHandler.adBanner.setAdListener(new AdListener() {
            @Override
            public void onAdLoaded() {
                super.onAdLoaded();
                Log.i(TAG, "Ad loaded ...");
            }
        });

        adHandler.adBanner.setAdSize(AdSize.SMART_BANNER);
        adHandler.adBanner.setAdUnitId("");
    }
    // You need to get a RelativeLayout reference for this method to work
    // I would get it from AndroidLauncher
    public void requestAds() {
        AdRequest.Builder builder = new AdRequest.Builder();
        builder.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);
        builder.addTestDevice("");

        RelativeLayout.LayoutParams adBannerParams = new 
        RelativeLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, 
        ViewGroup.LayoutParams.WRAP_CONTENT);
        adBannerParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
        adBannerParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);

        layout.addView(adHandler.adBanner, adBannerParams);
        adHandler.adBanner.loadAd(builder.build());
    }
}

的AdsManager

public interface AdsManager {
    void implementAds();
    void requestAds(); // Relative layout param removed from here
    void showAds(boolean show);
}

在此之后，如果您希望这些操作影响您的游戏，只需将您的游戏实例（核心模块）的引用传递给AndroidAdsManager中的AndroidLauncher，以便能够从那里调用您想要的任何方法，希望这会有所帮助！
