猜拳小游戏

阶段1：进行猜拳小游戏的布局

               

其代码如下：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:background="@drawable/ba" >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:padding="@dimen/padding_medium"        android:text="@string/choose"        tools:context=".MainActivity" />    <RadioGroup        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:orientation="horizontal">        <RadioButton             android:text="石头"            android:id="@+id/stone"            android:checked="true"/>        <RadioButton             android:text="剪刀"            android:id="@+id/scissors"/>        <RadioButton             android:text="布"            android:id="@+id/cloth"/>    </RadioGroup>    <Button         android:id="@+id/click"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="出拳" /></LinearLayout>

阶段2：编写电脑类和玩家类

电脑类：

package com.lks.model;public class Computer {public int show(){int quan;quan=(int) (Math.random()*10);if(quan<=2){quan=1;}else if(quan<=5){quan=2;}else{quan=3;}switch(quan){case 1:System.out.println("电脑出拳：石头");break;case 2:System.out.println("电脑出拳：剪刀");break;case 3:System.out.println("电脑出拳：布");break;}return quan;}}

玩家类：

package com.lks.model;public class Player {public int guess(String quan){int num=0;if(quan=="石头"){num=1;}else if(quan=="剪刀"){num=2;}else if(quan=="布"){num=3;}return num;}}

阶段3：编写猜拳游戏类，判定输赢

package com.lks.littlegame;import com.lks.model.Computer;import com.lks.model.Player;import android.os.Bundle;import android.app.Activity;import android.content.Intent;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.RadioButton;public class MainActivity extends Activity {private RadioButton stone;private RadioButton scissors;private RadioButton cloth;private Button clickButton;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        stone=(RadioButton) findViewById(R.id.stone);        scissors=(RadioButton) findViewById(R.id.scissors);        cloth= (RadioButton) findViewById(R.id.cloth);        clickButton=(Button) findViewById(R.id.click);                clickButton.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {String choose="";if(stone.isChecked()){choose="石头";}if(scissors.isChecked()){choose="剪刀";}if(cloth.isChecked()){choose="布";}Computer computer=new Computer();Player player=new Player();int a=computer.show();int b=player.guess(choose);String show="";if(a==1&&b==3||a==2&&b==1||a==3&&b==2){show="玩家 赢";}else if(a==1&&b==1||a==2&&b==2||a==3&&b==3){show="平局";}else if(a==3&&b==1||a==1&&b==2||a==2&&b==3){show="电脑 赢";}}});    }

阶段4：页面跳转传值

新建一个Activity,命名为GuessActivity.在layout中自动生成activity_guess.xml.其代码为：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"     android:background="@drawable/ba">    <TextView        android:id="@+id/result"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:padding="@dimen/padding_medium"        tools:context=".GuessActivity" /></RelativeLayout>

在MainActivity中嵌入代码：

Intent intent=new Intent();intent.setClass(MainActivity.this, GuessActivity.class);Bundle bundle=new Bundle();bundle.putString("choose", choose);bundle.putInt("a",a);bundle.putString("show", show);intent.putExtras(bundle);startActivity(intent);

在GuessActivity中接收MainActivity所传的值：

package com.lks.littlegame;import android.os.Bundle;import android.app.Activity;import android.view.Menu;import android.widget.TextView;public class GuessActivity extends Activity {    private TextView result;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_guess);        result=(TextView) findViewById(R.id.result);        Bundle bundle = this.getIntent().getExtras();        String choose = bundle.getString("choose");        int a=bundle.getInt("a");        String show=bundle.getString("show");        String fist="";        if(a==1){fist="石头";}else if(a==2){fist="剪刀";}else if(a==3){fist="布";}        result.setText("玩家："+choose+"\tVS\t"+"电脑："+fist+"\n"+show);    }

结果显示：
