unity 和android 交互之回调

unity 和android 交互之回调

当想调用androidSDK里面的接口，当接口里面的行为处理完了之后想要做其他的事时，我们怎么办呢？

如果你写死了，而且不能够随机应变。当需要处理其他的行为时。

例如：当你想调用androId原生广告播放接口时，当广告播放完之后你需要添加金币的行为，这个时怎么加入到接口中，这个就要用了回调了

首先需要在anroid里面加入一个回调接口

1.例如广告接口`

public interface AdCallback {void onDismissed();void onNoAd(AdError adError);void onComplete();void onPresent();void onClick();void onAdSkip();
}

2.需要在unity中也要添加一样的类

public class AdCallback : AndroidJavaProxy
{public Action Dismissed;public Action OnNoAd;public Action OnComplete;public Action OnPresent;public Action OnClick;public Action OnAdSkip;public AdCallback(string interfaceName) : base(interfaceName){}public void onDismissed(){Dismissed?.Invoke();}public void onNoAd(AndroidJavaObject adError){OnNoAd?.Invoke();}public void onComplete(){OnComplete?.Invoke();}public void onPresent(){OnPresent?.Invoke();}public void onClick(){OnClick?.Invoke();}public void onAdSkip(){OnAdSkip?.Invoke();}}

好了前期准备好了

现在就是需要添加广告接口
比如下面是广告接口的类

  public class PlayAd implements AdCallback{private AdCallback _adCallback public static void ShowReward(AdCallback adCallback) {Log.e("广告：", "广告");_adCallback = adCallback;//播放广告的逻辑}@Overridepublic void onDismissed() {_Dismissed();}@Overridepublic void onNoAd(AdError adError) {_NoAd(adError);}@Overridepublic void onComplete() {_Complete();}@Overridepublic void onPresent() {_Present();}@Overridepublic void onClick() {_Click();}@Overridepublic void onAdSkip() {_AdSkip();}}

然后就是在unity 里面调用了

public class NewAdMgr
{public const string AdCallbackPath = "com.bytedance.android";private AndroidJavaClass jcAd;public void Init(){
#if UNITY_ANDROIDjcAd = new AndroidJavaClass(AdCallbackPath );
#endif}public void ShowReward_Ad(AdCallback adCallback){//var  currentActivity = jc.GetStatic<AndroidJavaObject>("currentActivity");jcAd.CallStatic("ShowReward", adCallback);}public void ShowReward(){AdCallback adCallback = new AdCallback(AdCallbackPath);adCallback.Dismissed = () => { };ShowReward_Ad(adCallback);}
}

public void ShowReward(Action action)
{
AdCallback adCallback = new AdCallback(AdCallbackPath);
adCallback.Dismissed = () => { action?.Invoke();};
ShowReward_Ad(adCallback);
}
这个方法调用就是播放广告

欢迎各位大佬指出问题
