本文详细介绍了如何使用Android开发猜拳小游戏，包括页面布局、执行程序、结果显示及交互逻辑，并通过代码展示了如何实现玩家出拳、结果比较及反馈。

1、猜拳小游戏页面布置：activity_main.xml:

执行程序页面显示如下：

</LinearLayout>

返回结果的页面布局resultstyle.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/res"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="25px"
/>
</LinearLayout>

执行程序页面显示如下：

读取传递参数主要代码MainActivity：

package com.game.zzw;

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

public class MainActivity extends Activity {
/** Called when the activity is first created. */

private RadioButton rdoST, rdoJD, rdoB;
private Button btnSend;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// 设置当前的布局视图
setContentView(R.layout.activity_main);

rdoST = (RadioButton) findViewById(R.id.shitou);
rdoJD = (RadioButton) findViewById(R.id.jiandao);
rdoB = (RadioButton) findViewById(R.id.bu);
btnSend = (Button) findViewById(R.id.button1);

btnSend.setOnClickListener(new ViewBtnOcl());
}

class ViewBtnOcl implements View.OnClickListener {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.button1:
String ren = "0";
if (rdoST.isChecked()) {
ren = "1";
} else if (rdoJD.isChecked()) {
ren = "2";
} else {
ren = "3";
}
Intent intent = new Intent(MainActivity.this,
ResultActivity.class);
intent.putExtra("ren", ren);
startActivity(intent);
break;
}
}
}
}

结果比较返回值主要代码ResulActivity：

package com.game.zzw;

import java.util.Random;

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

public class ResultActivity extends Activity {

private TextView myTextView;

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.resultstyle);

myTextView = (TextView) findViewById(R.id.res);

Intent intent = getIntent();
int ren = Integer.parseInt(intent.getStringExtra("ren"));

// 业务逻辑判断
// 自动生成npc产生拳的代码(1~3)
int npc = new Random().nextInt(3) + 1;
// 处理请求数据并进行逻辑判断，将结果返回
String res = "";
if (ren == npc) {
res = "平局，再接再厉";
} else if (ren == 3 && npc == 1) {
res = "恭喜，您获胜了……";
} else if (ren == 1 && npc == 3) {
res = "虽败犹荣……再来一局";
} else if (ren < npc) {
res = "恭喜，您获胜了……";
} else {
res = "虽败犹荣……再来一局";
}

String msg = "您：" + change(ren) + " vs " + "电脑：" + change(npc)
+ "\n您" + res;

myTextView.setText(msg);

}

// 将数字转换成汉字
private String change(int r) {
switch (r) {
case 1:
return "石头";
case 2:
return "剪刀";
case 3:
return "布";
}
return null;
}

}
