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:
//unity
void gameobjectFunction(string parm)
{
}
//Java
UnityPlayer.UnitySendMessage("gameobjectName", "gameobjectFunction", "parms");
