先来看一下运行图:

接下来看一下主要的代码：

MainActivity.java

import java.util.Random;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RadioButton;

public class MainActivity extends Activity {
	RadioButton shitou,jiandao,bu;
	Button chuquan;
	int user,diannao;
	String [] xianshi = new String[3];
	Random random = new Random();
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        shitou = (RadioButton) findViewById(R.id.shitou);
        jiandao = (RadioButton) findViewById(R.id.jiandao);
        bu = (RadioButton) findViewById(R.id.bu);
        chuquan = (Button) findViewById(R.id.chuquan);
        chuquan.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {
				diannao = Math.abs(random.nextInt() % 3);
				user = 1;
				String userxinxi = null;
				if(shitou.isChecked()){  
					xianshi[0] = "剪刀";
					xianshi[1] = "石头";
					xianshi[2] = "布";
					userxinxi = "石头";
				}else if (jiandao.isChecked()) {
					xianshi[0] = "布";
					xianshi[1] = "剪刀";
					xianshi[2] = "石头";
					userxinxi = "剪刀";
				}else if (bu.isChecked()) {
					xianshi[0] = "石头";
					xianshi[1] = "布";
					xianshi[2] = "剪刀";
					userxinxi = "布";
				}
				
				Intent intent = new Intent(MainActivity.this,Result.class);
				intent.setFlags(RESULT_CANCELED);
				if(diannao > user){
					intent.putExtra("result", "玩家:"+userxinxi+"	vs	"+"电脑："+xianshi[diannao] + "\n电脑赢");
				}else if(diannao == user){
					intent.putExtra("result", "玩家:"+userxinxi+"	vs	"+"电脑："+xianshi[diannao] + "\n双方是平手");
				}else if(diannao < user){
					intent.putExtra("result", "玩家:"+userxinxi+"	vs	"+"电脑："+xianshi[diannao] + "\n玩家赢");
				}
				startActivity(intent);
			}
		});
    }
}

Result.java

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.widget.TextView;

public class Result extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.result);
        Intent intent = getIntent();
        String result = intent.getStringExtra("result");
        TextView jieguo = (TextView) findViewById(R.id.jieguo);
        jieguo.setText(result);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    
}
