如何在LibGDX项目中显示非页内广告？ [英] How to display a Interstitial Ad in a LibGDX project?

问题描述

我找到了一个Flappy Bird GitHub项目并稍微改了一下。
我成功实施了AdMob Banner。

I found a Flappy Bird GitHub project and changed it a little bit. I successfully implemented the AdMob Banner.

但是现在我还想要一个在游戏结束时弹出的非页内广告（当然不是每次都会出现）所以这是我的GitHub项目： https://github.com/DaFaack/FlappyBibi

But now I also want a Interstitial Ad which pops up when the Game is over (not every time of course) so here is my GitHub project: https://github.com/DaFaack/FlappyBibi

请解释我怎么做，因为我在网上找不到好的解释。

Please explain me how to do it because I can't find a good explanation on the internet.

我想在run（）方法中显示广告。你可以在核心包中找到它 - > GameplayScreen.java 文件 - > renderPlaying（）方法然后 run（）方法。

I want to display the ad in the run() method. You can find it in the core package -> GameplayScreen.java File -> renderPlaying() method and then the run() method.

这是我所说的方法：

    private void renderPlaying() {
        if (justTouched) {
            bird.jump();
            justTouched = false;

        }
        updatePipePairs();
        gameplayStage.act();
        uiStage.act();
        checkCollisions();
        if (bird.getState() == Bird.State.DYING) {
            stopTheWorld();


            RunnableAction playWooshAction = Actions.run(new Runnable() {
                @Override
                public void run() {
                    com.pentagames.flappybibi.Assets.playWooshSound();

//Here I want to display the Interstitial Ad!

                }
            });

游戏结束后，如何显示插页式广告？

What do I have to do to display the Interstitial Ad when the game is over?

这是我的AndroidLauncher.java文件：

This is my AndroidLauncher.java file:

package com.pentagames.flappybibi.android;

import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.RelativeLayout;

import com.pentagames.flappybibi.FlappyGame;

public class AndroidLauncher extends AndroidApplication{

    private static final String TAG = "AndroidLauncher";
    protected AdView adView;

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

        RelativeLayout layout = new RelativeLayout(this);

        AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
        View gameView=initializeForView(new FlappyGame(), config);
        layout.addView(gameView);

        adView = new AdView(this);
        adView.setAdListener(new AdListener(){
            @Override
            public void onAdLoaded(){
                int visibility = adView.getVisibility();
                adView.setVisibility(AdView.GONE);
                adView.setVisibility(AdView.VISIBLE);
                Log.i(TAG, "Ad Loaded...");
            }
        });
        adView.setAdSize(AdSize.SMART_BANNER);
        adView.setAdUnitId("ca-app-pub-XXXXXXXXXXXXXX/XXXXXXXXX");

        AdRequest.Builder builder = new AdRequest.Builder();
        RelativeLayout.LayoutParams adParams = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.MATCH_PARENT,
                RelativeLayout.LayoutParams.WRAP_CONTENT
        );
        adParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
        adParams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);

        layout.addView(adView, adParams);
        adView.loadAd(builder.build());

        setContentView(layout);
    }

    @Override
    protected void onResume() {
        super.onResume();
        adView.resume();
    }

    @Override
    protected void onPause() {
        super.onPause();
        adView.pause();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        adView.destroy();
    }
    }

这是我第一次使用LibGDX，如果你能解释我如何在这个项目中实现插页式广告，那将会很棒。

This is the first time that I'm working with LibGDX, would be great if you can explain me how to implement the Interstitial Ad in this project.

抱歉我的英语不好。

推荐答案

您已经集成了横幅广告，因此无需在项目中注入相关工件。

You already integrated banner Ad so no need to injected dependent artifact in your project.

按照以下步骤进行插页式广告整合。

Follow these steps for Interstitial Ad integration.

1. AndroidManifest.xml

为非页内广告输入 AdActivity

<activity android:name="com.google.android.gms.ads.AdActivity"
          android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
          android:theme="@android:style/Theme.Translucent" />

在核心模块内创建一个界面

Create an interface inside your core module

public interface AdService {

   boolean isInterstitialLoaded();
   void showInterstitial();
}

创建 FlappyGame <的参数化构造函数/ code> class

Create a parameterized constructor of FlappyGame class

public AdService adService;

public FlappyGame(AdService ads){
     adService=ads;
}

实施 AdService 接口到 AndroidLauncher 类

public class AndroidLauncher extends AndroidApplication implements AdService {

    private static final String AD_UNIT_ID_INTERSTITIAL = "ca-app-pub-XXXXX/XXXXX";
    private InterstitialAd interstitialAd;

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

         ...
         View gameView=initializeForView(new FlappyGame(this), config);
