Unity Android Callback

Unity Android Callback

在 Unity 建立一個 Callback 讓 Android plugin 做完某事之後呼叫.


一、Eclipse
1. 建立一個 interface

例:

public interface CAdLocusListenerCallBack { void onReceiveAd(); void onFailedToReceiveAd(int errorcode);}

2. 把它加入至某 class 裡

例:

public class CAdLocus{    //callback.    CAdLocusListenerCallBack listenerCB = null;    public void SetListenerCB(CAdLocusListenerCallBack cb)    {     listenerCB = cb;    }}

3.做完事後呼叫 Callback

例:

       public void onReceiveAd(Ad adView )       {        //AdLocusLayout llayout = (AdLocusLayout)adView;        if (listenerCB != null)        {         listenerCB.onReceiveAd();        }       }       public void onFailedToReceiveAd(Ad adView , com.adlocus.AdLocusLayout$ErrorCode errorCode)       {         if (listenerCB != null)         {          listenerCB.onFailedToReceiveAd(1);         }       }

二、Unity

1.建立 Callback 腳本

例:

public class AdLocusListenerCallBack : AndroidJavaProxy{ public AdLocusListenerCallBack():base("com.ad.adlocus.CAdLocusListenerCallBack") { } void onReceiveAd() { } void onFailedToReceiveAd(int errorcode) { }}

2.對 Plugin 註冊 Callback

例:

AndroidJavaClass player = new AndroidJavaClass( "com.unity3d.player.UnityPlayer" );AndroidJavaObject activity = player.GetStatic<AndroidJavaObject>("currentActivity");AdLocusJo = new AndroidJavaObject("com.ad.adlocus.CAdLocus", activity);AdLocusListenerCallBack AdListenerCB = new AdLocusListenerCallBack();AdLocusJo.Call("SetListenerCB", AdListenerCB);

四、最後
也有人是直 sendmessage 的方式接調用 Unity 物件的函式,
例:

//unityvoid gameobjectFunction(string parm){}//JavaUnityPlayer.UnitySendMessage("gameobjectName", "gameobjectFunction", "parms");
