猜拳小游戏

一.任务描述

二.编写过程

1.阶段一：进行页面布局

<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:background="@drawable/pg"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/chosetext" />
</LinearLayout>

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >

<RadioGroup
android:id="@+id/Radiogroup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >

<RadioButton
android:id="@+id/Button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/shitou" />

<RadioButton
android:id="@+id/Button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/jiandao" />

<RadioButton
android:id="@+id/Button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/bu" />
</RadioGroup>
</LinearLayout>

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >

<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/click" />
</LinearLayout>

</LinearLayout>

布局效果如下：

2.阶段二：编写电脑类和玩家类

public void onCheckedChanged(RadioGroup group, int checkedId) {

// TODO Auto-generated method stub
switch(checkedId){
case R.id.Button1:
Pchose=1;
personchoose=button1.getText().toString();
break;
case R.id.Button2:
Pchose=2;
personchoose=button2.getText().toString();
break;
case R.id.Button3:
Pchose=3;
personchoose=button3.getText().toString();
break;
default:
break;
}

Cchose=(int)Math.random()*10%3+1;//电脑随机产生数字1-3
switch(Cchose){
case 1:
computerchoose=button1.getText().toString();
break;
case 2:
computerchoose=button2.getText().toString();
break;
case 3:
computerchoose=button3.getText().toString();
break;

}
}

});

3.阶段三：编写猜拳游戏类，判定输赢

if(computerchoose.equals(personchoose))
{
score="平局";

}
else if((personchoose.equals("剪刀") && computerchoose.equals("石头"))||(personchoose.equals("石头") && computerchoose.equals("布"))||(personchoose.equals("布") &&computerchoose.equals("剪刀")))
{
score="玩家赢";
}
else
{
score="电脑赢";
}

Toast.makeText(this, score, Toast.LENGTH_LONG).show();
showResult.setText("玩家："+personchoose+"VS电脑："+computerchoose+"\n"+score);

4.阶段四：页面跳转传值

public void onClick(View v) {

// TODO Auto-generated method stub
Intent intent = new Intent();
Bundle bundle = new Bundle();
bundle.putString("computerchoose", computerchoose);
bundle.putString("personchoose", personchoose);
intent.putExtras(bundle);
intent.setClass(MainActivity.this, SecondActivity.class);
startActivity(intent);
}

intent=getIntent();
Bundle bundle=intent.getExtras();
personchoose=bundle.getString("personchoose");
computerchoose=bundle.getString("computerchoose");
