该Android应用包含MainActivity和GameActivity两个主要活动。MainActivity中用户输入名字并选择游戏难度，通过Intent传递数据到GameActivity。GameActivity显示游戏界面，有时间限制和得分系统，用户点击地鼠按钮进行游戏。游戏难度不同，地鼠出现的速度也不同。

项目结构

用到的三张图片

mainActivity如下

package com.example.myapplication;

import androidx.appcompat.app.AlertDialog;
import androidx.appcompat.app.AppCompatActivity;

import android.content.DialogInterface;
import android.content.Intent;
import android.os.Bundle;
import android.text.Editable;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    private EditText editText;
    private Button buttonLevel;
    private Button buttonStart;
    private String userName;
    private int gameLevel=1000;//easy=2000,commmon=1000.hard=500ms



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        editText=findViewById(R.id.editText);
        buttonLevel=findViewById(R.id.buttonLevel);
        buttonStart=findViewById(R.id.buttonStart);

        buttonLevel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //单选对话框
                AlertDialog alertDialog=new AlertDialog.Builder(MainActivity.this)
                        .setTitle("请选择难度：")
                        .setSingleChoiceItems(new String[]{"简单", "普通", "困难"}, 1, new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialogInterface, int i) {
                                if(i==0) gameLevel=2000;
                                if(i==1) gameLevel=1000;
                                if(i==2) gameLevel=500;
                                Toast.makeText(MainActivity.this,gameLevel+"",Toast.LENGTH_SHORT).show();//在面包片上测试一下i可以用吗
                            }
                        })//单选
                        .setPositiveButton("确定",null)
                        .create();
                alertDialog.show();

            }
        });
        buttonStart.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                userName=editText.getText().toString();//用户输入的用户名
                //显式跳转
                Intent intent=new Intent(MainActivity.this,GameActivity.class);
                intent.putExtra("userName",userName);
                intent.putExtra("gameLevel",gameLevel);
                startActivity(intent);

            }
        });
    }
}

mainlayout如下
