unity3d调用jar类中的方法和属性

这里用的unity3d的版本是5.3.2

在eclipse里新建一个java工程，并导出成jar。

package com.innyo.androidplugin;

public class apTest {

  public apTest(String inString) {
    tryProp = "propties is ok.<" + inString + ">";
  }

  public String tryProp = "public propties is return.";

  public static String tryStaticProp = "static propties is return.";

  public String TryPublic() {
    return "public method run ok.";
  }

  public String TryPublic(String inString) {
    return "public method with prop run ok.<" + inString + ">";
  }

  public static String TryStaticPublic() {
    return "static public method run ok.";
  }

  public static String TryStaticPublic(String inString) {
    return "static public method whith prop run ok.<" + inString + ">";
  }
}

导出为jar

新建unity3d工程，导入jar文件。

新建一个场景，把内容输出到text上显示，

using UnityEngine;
using System.Collections;
using System;
using UnityEngine.UI;

public class TryPlugin : MonoBehaviour
{

  public Text t;

  public void ToTry ()
  {
    try {
      t.text = "start android plugins";

      t.text = t.text + "\r\n";
      AndroidJavaClass jc = new AndroidJavaClass ("com.innyo.androidplugin.apTest");
      t.text = t.text + "AndroidJavaClass jc:" + jc.ToString ();

      t.text = t.text + "\r\n";
      t.text = t.text + "tryProp:" + jc.Get<string> ("tryProp");

      t.text = t.text + "\r\n";
      t.text = t.text + "tryStaticProp:" + jc.GetStatic<string> ("tryStaticProp");

      t.text = t.text + "\r\n";
      t.text = t.text + "TryPublic:" + jc.Call<string> ("TryPublic");

      t.text = t.text + "\r\n";
      t.text = t.text + "TryPublic:" + jc.Call<string> ("TryPublic", "unity3d input");

      t.text = t.text + "\r\n";
      t.text = t.text + "TryStaticPublic:" + jc.CallStatic<string> ("TryStaticPublic");

      t.text = t.text + "\r\n";
      t.text = t.text + "TryStaticPublic:" + jc.CallStatic<string> ("TryStaticPublic", "unity3d input");

      t.text = t.text + "\r\n";
      t.text = t.text + "----------------------------------------";

      t.text = t.text + "\r\n";
      AndroidJavaObject jo = new AndroidJavaObject("com.innyo.androidplugin.apTest","unity3d jo build");
      t.text = t.text + "AndroidJavaObject jo:" + jo.ToString ();

      t.text = t.text + "\r\n";
      t.text = t.text + "tryProp:" + jo.Get<string> ("tryProp");

      t.text = t.text + "\r\n";
      t.text = t.text + "tryStaticProp:" + jo.GetStatic<string> ("tryStaticProp");

      t.text = t.text + "\r\n";
      t.text = t.text + "TryPublic:" + jo.Call<string> ("TryPublic");

      t.text = t.text + "\r\n";
      t.text = t.text + "TryPublic:" + jo.Call<string> ("TryPublic", "unity3d input");

      t.text = t.text + "\r\n";
      t.text = t.text + "TryStaticPublic:" + jo.CallStatic<string> ("TryStaticPublic");

      t.text = t.text + "\r\n";
      t.text = t.text + "TryStaticPublic:" + jo.CallStatic<string> ("TryStaticPublic", "unity3d input");

    } catch (Exception ex) {
      t.text = t.text + "\r\n";
      t.text = t.text + ex.Message;
    }
  }
}

编译成安卓，然后运行，点击按钮，可以看到以下结果

AndroidJavaClass只能调用静态方法，获取静态属性

AndroidJavaObject能调用公开方法和公开属性

另外，jar文件，不一定非要放在plugins/android目录下。

例子代码：​​javascript:void(0)​​

=====================================

如果是调用jar类中的枚举，而且枚举必须不是类下面的，方法如下

java

package com.innyo.androidplugin;

public enum TryEnum {
  red,green,yellow,blcak

}

unity3d

AndroidJavaObject redValue = 
  new AndroidJavaClass("com.innyo.androidplugin.TryEnum").GetStatic<AndroidJavaObject>("red");

如果是调用jar类中的接口，实在是不会在java中写事件接口，只好拿别人的用。

unity3d

public class DateCallback : AndroidJavaProxy
{
  public DateCallback ()
    : base ("com.amap.api.location.AMapLocationListener")
  {
  }

  void onLocationChanged (AndroidJavaObject amapLocation)
  {
    
  }
}

等效于java中写

public class Hight_Accuracy_Activity implements AMapLocationListener {

  @Override
  public void onLocationChanged(AMapLocation loc) {

  }
}
