unity导出成安卓工程，集成到安卓显示

unity调用安卓方法：https://blog.csdn.net/AllBluefm/article/details/155520167?sharetype=blogdetail&sharerId=155520167&sharerefer=PC&sharesource=AllBluefm&spm=1011.2480.3001.8118

1、unity导出成安卓工程，导完是文件夹形式

2、用Android Studio打开导出的unity工程，按照步骤把tuanjieLibrary打成aar包，期间可能需要配置gradle的版本

3、将aar放入到安卓工程中，引用这个aar

4、采用fragment的方式，将unity引入，此时就能看到unity的内容了

package com.honda.dic.settings.ui.fragment;

import android.graphics.Color;
import android.graphics.PixelFormat;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.SurfaceView;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.widget.FrameLayout;

import androidx.fragment.app.Fragment;

import com.unity3d.player.UnityPlayer;

public class UnityContentFragment extends Fragment {

    public static UnityPlayer mUnityPlayer;
    View view;
    public UnityContentFragment() {
        // 必须有一个无参数构造函数
    }
    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        mUnityPlayer = new UnityPlayer(requireActivity());
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view = mUnityPlayer.getView();
        if(view.getParent()!=null)
        {
            ((ViewGroup)view.getParent()).removeAllViews();
        }
        view.getViewTreeObserver().addOnWindowFocusChangeListener((has)->mUnityPlayer.windowFocusChanged(has));

        return view;
    }

    @Override
    public void onResume() {
        super.onResume();
        mUnityPlayer.resume();
    }

    @Override
    public void onPause() {
        super.onPause();
        mUnityPlayer.pause();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mUnityPlayer.quit();
    }
}
