android猜拳小遊戲

“石頭剪刀布”誰都玩過，趕快做個小遊戲和電腦玩吧！

一：佈局：

activity_main.xml

<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/bg" >

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:padding="@dimen/padding_medium"
        android:text="請您選擇要出的拳"
        tools:context=".MainActivity" />

    <RadioGroup
        android:id="@+id/radioGroup1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/textView" >

        <RadioButton
            android:id="@+id/radio0"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:checked="true"
            android:text="剪刀" />

        <RadioButton
            android:id="@+id/radio1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="石頭" />

        <RadioButton
            android:id="@+id/radio2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="布" />
    </RadioGroup>

    <Button
        android:id="@+id/click"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/radioGroup1"
        android:layout_marginTop="26dp"
        android:text="出拳" />

</RelativeLayout>

二：實現類：

1）電腦類：

public class Computer {
	public int show(){
		int quan;
		quan=(int) (Math.random()%0.3);
		if(quan==0){
			quan=1;
		}
		 if(quan==1){
			quan=2;
		}
		 if(quan==2){
			quan=3;
		}
		switch(quan){
		case 1:System.out.println("電腦出拳：石頭");break;
		case 2:System.out.println("電腦出拳：剪刀");break;
		case 3:System.out.println("電腦出拳：布");break;
		}
		return quan;
	}

}

2）玩家類：

package w3.dyp.model;

public class Player {
	public int play(String choose) {
		int number;

		if (choose == "剪刀") {
			number = 1;
		} else if (choose == "石頭") {
			number = 2;
		} else {
			number = 3;
		}
		return number;
	}
}

三：主要編輯類：

MainActivity：

public class MainActivity extends Activity {
    private TextView  textview;
    private RadioButton radio0;
	private RadioButton radio1;
	private RadioButton radio2;
	private Button click; 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        radio0 = (RadioButton) findViewById(R.id.radio0);
        radio1 = (RadioButton) findViewById(R.id.radio1);
        radio2 = (RadioButton) findViewById(R.id.radio2);
        click =(Button)findViewById(R.id.click);
        click.setOnClickListener(new OnClickListener() {
        	public void onClick(View v) {
        		String choose="";
        		if (radio0.isChecked()) {
					choose = "剪刀";
				}
        		if(radio1.isChecked()){
        			choose="石頭";
        		}
        		if(radio2.isChecked()){
        			choose="布";
        		}
        		Player player=new Player();
        		Computer computer=new Computer();
        		int a=player.play(choose);
        		int b=computer.show();
        		 String result="";
        		if(a>b){
        			result="玩家贏";
        		}else if(a==b){
        			result="平局";
        		}else {
        			result="電腦贏";
        		}
        		Toast.makeText(MainActivity.this,"玩家出"+choose+""+result,Toast.LENGTH_LONG).show();
        	}
        });
    }

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

    
}

劃線部分，能讓結果顯示在主頁面上而不用跳轉傳值。

跳轉傳值時，需要把劃線地方刪了，再做以下修改：

1)新建一個Activity類，修改其自動生成的佈局文件：

<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" >

    <TextView
        android:id="@+id/result"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="@dimen/padding_medium"
        tools:context=".ShowActivity" />

</RelativeLayout>

 2)在MainActivity中添加：

<SPAN style="FONT-SIZE: 12px">Intent intent=new Intent();  
                 intent.setClass(MainActivity.this, ShowActivity.class);  
                 Bundle bundle=new Bundle();  
                 bundle.putString("choose", choose);  
                 bundle.putInt("a",a);  
                 bundle.putString("reslt", result);  
                intent.putExtras(bundle);  
                 startActivity(intent);</SPAN> 

3）ShowActivity類：

 

 

package w3.dyp.xiaogame;

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

public class ShowActivity extends Activity {

	private TextView result;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_show);
		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 = "剪刀";
		} else if (a == 2) {
			fist = "石頭";
		} else if (a == 3) {
			fist = "布";
		}
		
		result.setText("玩家：" + choose + "\tVS\t" + "電腦：" + fist + "\n" + show);
	}

}

 

結果顯示：

剛發現沒截圖，截上圖就舒服多了，也好看了！
