猜拳小游戏

一、要求

阶段1：进行猜拳小游戏的布局
阶段2：编写电脑类和玩家类
阶段3：编写猜拳游戏类，判定输赢
阶段4：页面跳转传值

二、具体实现代码

1、activity_main.xml

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/bj"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="请选择你要出的拳:"
        android:textColor="#FF0000"
        android:textSize="30sp" />

    <RadioGroup
        android:id="@+id/radiogroupe"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" >

        <RadioButton
            android:id="@+id/Stone"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="石头"
            android:textSize="20sp" />

        <RadioButton
            android:id="@+id/Scissors"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="剪刀"
            android:textSize="20sp" />

        <RadioButton
            android:id="@+id/Cloth"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="布"
            android:textSize="20sp" />
    </RadioGroup>

    <Button
        android:id="@+id/quchuan"
        android:layout_width="179dp"
        android:layout_height="wrap_content"
        android:layout_marginLeft="70dp"
        android:text="出拳"
        android:textSize="20sp" />

</LinearLayout>

2、result.xml

<?xml version="1.0" encoding="UTF-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" 
    android:background="@drawable/bj">

    <TextView
        android:id="@+id/result"
        android:textSize="30sp"
        android:textColor="#FF0000"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

3、MainActivity.java

package com.example.guess;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RadioGroup;

public class MainActivity extends Activity {

	private RadioGroup radioGroup;
	private Button button;
	private OnClickListener listener = new OnClickListener() {

		public void onClick(View v) {
			switch (v.getId()) {
			case R.id.quchuan:
				// 获得所选择的拳
				int id = radioGroup.getCheckedRadioButtonId();
				int quan = 0;
				// 根据不同的选择 给一个整型值赋值 石头1 剪刀2 布3
				switch (id) {
				case R.id.Stone:
					quan = 1;
					break;
				case R.id.Scissors:
					quan = 2;
					break;
				case R.id.Cloth:
					quan = 3;
					break;

				default:
					break;
				}
				// 启动结果页面 并传值
				Intent intent = new Intent();
				intent.setClass(MainActivity.this, ResultActivity.class);
				intent.putExtra("quan", quan);
				startActivity(intent);
				break;

			default:
				break;
			}

		}
	};

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		radioGroup = (RadioGroup) findViewById(R.id.radiogroupe);
		button = (Button) findViewById(R.id.quchuan);
		button.setOnClickListener(listener);
	}

}

4、ResultActivity.java

package com.example.guess;
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 textview;
	protected void onCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
		setContentView(R.layout.result);
		textview=(TextView)findViewById(R.id.result);
		Intent intent=getIntent();
		Bundle bundle=intent.getExtras();
		 int ren=bundle.getInt("quan");
		//电脑出的拳
		 Random random=new Random();
		 int cpu=random.nextInt(3-1)+1;
		 String result=compare(ren ,cpu);
		  textview.setText(result);
	}
	private String compare(int ren ,int cpu){
		StringBuffer show=new StringBuffer("结果:\n"+"人:"+xianshi(ren)+"  VS  "+"电脑:"+xianshi(cpu)+"\n");
		if (ren==cpu) {
		show.append("哈哈，平局！");	
		}else if(ren==1 && cpu==3){
		show.append("电脑胜，你输啦！");	
		}else if(ren==3 && cpu==1){
			show.append("人胜，真厉害！");	
		}else if(ren<cpu){
			show.append("人胜，真厉害！");	
		}else if(ren>cpu){
			show.append("电脑胜，你输啦！");	
		}
		return show.toString();
	}
private String xianshi(int id){
		
		switch (id) {
		case 1:
			return "石头";
        case 2:
        	return "剪刀";		
        case 3:
        	return "布";
		default:
			break;
		}
		return null;
	}
}

5、Strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">猜拳游戏</string>
    <string name="action_settings">Settings</string>
   
</resources>

6、AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.guess"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.guess.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".ResultActivity"
            android:label="@string/app_name" >
        </activity>
    </application>

</manifest>
