【Unity调用原生安卓】4.调用安卓接口AndroidJavaProxy

目录

官方例子

注意java接口和Unity对应

之前有三个基础篇

1.入门篇 ——实现原生安卓Log

2.进阶篇 Toast、打开应用、安装/卸载应用、获取应用列表、对话框、发送广播、获取所有包名

3.总结篇 总结一般用法

官方例子

using UnityEngine;
using System;
 
class ExampleClass : MonoBehaviour 
{
    private static DateTime selectedDate = DateTime.Now;
 
    class DateCallback : AndroidJavaProxy
    {
        public DateCallback() : base("android.app.DatePickerDialog$OnDateSetListener") { }
        void onDateSet(AndroidJavaObject view, int year, int monthOfYear, int dayOfMonth)
        {
            selectedDate = new DateTime(year, monthOfYear+1, dayOfMonth);
        }
    }
 
    void OnGUI ()
    {
        if (GUI.Button(new Rect (15, 15, 450, 75), string.Format("{0:yyyy-MM-dd}", selectedDate)))
        {
            AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity");
            activity.Call("runOnUiThread", new AndroidJavaRunnable(() =>
            {
                new AndroidJavaObject("android.app.DatePickerDialog", activity, new DateCallback(), selectedDate.Year, selectedDate.Month-1, selectedDate.Day).Call("show");
            }));
        }
    }
}

注意java接口和Unity对应

1.如果java接口单独是一个脚本，unity对应为：包名.接口名，即“com.xxx.xxx.interfaceName”

安卓端

 unity端

    public class FaceTrackPcData : AndroidJavaProxy
    {
        public FaceTrackPcData() : base("com.xhsj.pc_to_android.FaceTrackPcData") { }
        public void faceData(string paramString)
        {
            if (receiveDataCall != null)
            {
                receiveDataCall(paramString);
            }
        }
        public delegate void ReceiveDataCallback(string msg);
        public ReceiveDataCallback receiveDataCall;
    }

2.如果java接口是在类内部，unity对应为：包名.类名￥接口名，也就是官方的例子
