如何在 LibGDX 项目中显示插页式广告?
我找到了一个 Flappy Bird 的 GitHub 项目并稍作改动.我成功实施了 AdMob 横幅.
I found a Flappy Bird GitHub project and changed it a little bit. I successfully implemented the AdMob Banner.
但现在我还想要一个在游戏结束时弹出的插页式广告(当然不是每次都弹出)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
请解释一下怎么做，因为我在互联网上找不到很好的解释.
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.您可以在核心包 -> GameplayScreen.java 文件 -> renderPlaying() 方法中找到它，然后在 run() 方法中找到它.
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.
这就是我说的方法:
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!
}
});
游戏结束后我要怎么做才能显示插页式广告?
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 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，那就太好了.
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.
对不起，我的英语不好.
Sorry for my bad English.
推荐答案
您已经集成了横幅广告，因此无需在项目中注入依赖工件.
You already integrated banner Ad so no need to injected dependent artifact in your project.
按照这些步骤进行插页式广告集成.
Follow these steps for Interstitial Ad integration.
AndroidManifest.xml
为插页式广告输入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" />
在你的核心模块中创建一个接口
Create an interface inside your core module
public interface AdService {
boolean isInterstitialLoaded();
void showInterstitial();
}
创建FlappyGame类的参数化构造函数
public AdService adService;
public FlappyGame(AdService ads){
adService=ads;
}
为您的 AndroidLauncher 类实现 AdService 接口
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);
...
interstitialAd = new InterstitialAd(this);
interstitialAd.setAdUnitId(AD_UNIT_ID_INTERSTITIAL);
interstitialAd.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {}
@Override
public void onAdClosed() {
loadIntersitialAd();
}
});
loadIntersitialAd();
}
private void loadIntersitialAd(){
AdRequest interstitialRequest = new AdRequest.Builder().build();
interstitialAd.loadAd(interstitialRequest);
}
@Override
public void showInterstitial() {
runOnUiThread(new Runnable() {
public void run() {
if (interstitialAd.isLoaded())
interstitialAd.show();
else
loadIntersitialAd();
}
});
}
@Override
public boolean isInterstitialLoaded() {
return interstitialAd.isLoaded();
}
}
GameScreen 类
RunnableAction playWooshAction = Actions.run(new Runnable() {
@Override
public void run() {
com.pentagames.flappybibi.Assets.playWooshSound();
game.adService.showInterstitial();
}
});
我在您的项目中集成了插页式广告，并为此创建了 拉取请求.你可以合并我的拉取请求.
I integrated Interstitial Ad in your project, created a pull request for the same. You can merge my pull request.
