一，添加Activity，命名为MyLaunchActivity

二，编写MyLaunchActivity.java的内容

package com.cocos.game.launch;

import android.os.Bundle;

import androidx.activity.EdgeToEdge;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.graphics.Insets;
import androidx.core.view.ViewCompat;
import androidx.core.view.WindowInsetsCompat;
import fish.create.light.R;

import android.widget.FrameLayout;
import android.webkit.WebView;
import android.widget.TextView;
import android.widget.Button;
import android.view.View;
import android.webkit.WebSettings;
import android.view.KeyEvent;
import android.content.Intent;
import android.app.Activity;


import com.cocos.game.AppActivity;


//AppCompatActivity
public class MyLaunchActivity extends Activity {

//    @Override
//    protected void onCreate(Bundle savedInstanceState) {
//        super.onCreate(savedInstanceState);
//        EdgeToEdge.enable(this);
//        setContentView(R.layout.my_launch);
//        ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main), (v, insets) -> {
//            Insets systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars());
//            v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom);
//            return insets;
//        });
//    }



    private static String _agreedSymbol = "AGREE_HQ_SERVICE";
    private MyPrivacyDialog _agrementDialog=null;
    private FrameLayout _bgLayout=null;
    private TextView _titleTxt=null;
    private WebView _webView=null;
    private Button _exitBtn=null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_launch);
        initShow();
        initDialog();
    }

    private void initShow(){
        _bgLayout=findViewById(R.id.launch_con_node);
        _titleTxt=findViewById(R.id.launch_title);
        _exitBtn=findViewById(R.id.launch_exitBtn);
        _exitBtn.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v){
                if(_agrementDialog!=null){
                    _agrementDialog.show();
                }
                _bgLayout.setVisibility(View.GONE);
            }
        });

        _webView=findViewById(R.id.launch_WebView);
        WebSettings settings = _webView.getSettings();
        settings.setJavaScriptEnabled(true);
        settings.setDefaultTextEncodingName("UTF-8");
        //自适应手机屏幕
        settings.setUseWideViewPort(true);
        settings.setLoadWithOverviewMode(true);

        _bgLayout.setVisibility(View.GONE);
    }

    private void initDialog(){
        boolean states= (boolean) SPUtil.get(getApplication(),_agreedSymbol,false);
        if (states==false)
        {
            _agrementDialog = new MyPrivacyDialog(this);
            _agrementDialog.show();
            _agrementDialog.setOnBtnClickListener(new MyPrivacyDialog.OnBtnClickListener(){
                @Override
                public void onClick(int type) {
                    switch (type) {
                        case MyPrivacyDialog.ARGEEMENT_TEXT_CLICK://查看用户协议
                            loadUrl(getResources().getString(R.string.url_service),getResources().getString(R.string.user_service));
                            break;
                        case MyPrivacyDialog.SECRET_TEXT_CLICK://查看隐私协议
                            _agrementDialog.hide();
                            loadUrl(getResources().getString(R.string.url_private),getResources().getString(R.string.user_private));
                            break;
                        case MyPrivacyDialog.NOT_ARGEE_BTN_CLICK://不同意按钮
                            _agrementDialog.dismiss();
                            finish();
                            break;
                        case MyPrivacyDialog.ARGEE_BTN_CLICK: //同意按钮
                            _agrementDialog.dismiss();
                            SPUtil.put(getApplication(),_agreedSymbol,true);
                            jumpGameActivity();
                            break;
                    }
                }
            });
        }
        else{
            jumpGameActivity();
        }
    }

    private void loadUrl(String url,String str){
        _bgLayout.setVisibility(View.VISIBLE);
        _titleTxt.setText(str);
        _webView.loadUrl(url);

        _agrementDialog.hide();
    }

    public void jumpGameActivity() {
        // 闪屏结束后，跳转到游戏界面
        Intent intent = new Intent(this, AppActivity.class);
        startActivity(intent);
        this.finish();
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event)
    {
        if (keyCode == KeyEvent.KEYCODE_BACK)
        {

        }
        return true;
    }






}

三，编写my_launch.xml内容

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:l
