新建Unity工程

unity泛型单例脚本

SingletonUnity.cs

using UnityEngine;
public class SingletonUnity<T> : MonoBehaviour where T : MonoBehaviour
{   
    public static T instance = null;
    public virtual void Awake()
    {
        if (instance == null)
        {
            DontDestroyOnLoad(gameObject);
            instance = (T)FindObjectOfType(typeof(T));
        }
        else if (instance != null)
        {
            Destroy(gameObject);
        }
    }
}

调用Java脚本

MobPlugin .cs

using UnityEngine;

public class MobPlugin : SingletonUnity<MobPlugin>
{
#elif UNITY_ANDROID && !UNITY_EDITOR
    AndroidJavaClass jc;
    AndroidJavaObject activity;
#endif

    public void Start()
    {
#if UNITY_ANDROID && !UNITY_EDITOR
        jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        activity = jc.GetStatic<AndroidJavaObject>("currentActivity");
        activity.Call("SetSplashGone");
#endif
    }

    public void UnityToast(string msg)
    {
#if UNITY_ANDROID && !UNITY_EDITOR
        activity.Call("unityToast", msg);
#endif
        Debug.Log("UnityToast:" + msg);
    }

    public void AndroidToast(string msg)
    {
        TestAndroid testAndroid = GetComponent<TestAndroid>();
        if (testAndroid!=null)
        {
            testAndroid.Toast(msg);
        }
    }
}

测试脚本

TestAndroid.cs

using UnityEngine;
using UnityEngine.UI;

public class TestAndroid : MonoBehaviour {
    public Text text;
    public void UnityToast() {
        MobPlugin.instance.UnityToast("Unity中点击了按钮");
    }

    public void Toast(string msg)
    {
        if (text)
        {
            text.text = msg;
        }
    }
}

简易unity界面搭建

unity导出设置

包名可以随意命名之后用不到该包名

新建Android工程

这里使用Android 8.0

因为Google play的要求

新建空Activity

新建一个模块作为unity模块供主模块调用，让代码更简洁

settings.gradle中要包含unity模块

在app模块添加依赖

  implementation project(':unitylib')

修改UnityPlayerActivity.java

package com.apen.unitylib;//package com.apen.uni;将之前的包名修改为库模块的包名

import com.unity3d.player.*;
import android.app.Activity;
import android.content.Intent;
import android.content.res.Configuration;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.view.View;
import android.widget.RelativeLayout;

public class UnityPlayerActivity extends Activity
{
    protected UnityPlayer mUnityPlayer;

     /**
     *  设置父视图
     */
    public void setView(RelativeLayout mParent){
        this.mUnityPlayer = new UnityPlayer(this);
        View mView = this.mUnityPlayer.getView();
        mParent.addView(mView);
        this.mUnityPlayer.requestFocus();
    }

....//打包后生成的代码保留，仅删除protected void onCreate(Bundle savedInstanceState) {}方法，为了之后继承该activity不出错
}

在app模块中继承UnityPlayerActivity并设置视图

package com.apen.unity;

import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.FrameLayout;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.Toast;
import com.unity3d.player.UnityPlayer;
import com.apen.unitylib.UnityPlayerActivity;


public class UnityActivity extends WebActivity {
    RelativeLayout mParent;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_unity);

        mParent=findViewById(R.id.UnityView);
        setView(mParent);
        findViewById(R.id.androidclick).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                UnityPlayer.UnitySendMessage("TestAndroid", "Toast", "Android中点击了按钮");
            }
        });
    }
    public void unityToast(final String msg) {
        new Thread(new Runnable() {
            @Override
            public void run() {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(UnityActivity.this, msg, Toast.LENGTH_LONG).show();
                    }
                });
            }
        }).start();
    }
}

视图xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".UnityActivity">
    <RelativeLayout
        android:id="@+id/UnityView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
    <TextView
        android:id="@+id/androidclick"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TestAndroid"/>
</RelativeLayout>

配置Android 清单文件

    android:installLocation="preferExternal">
