剪刀、石头、布

1、布局设计_Mainactivity

使用线性布局之间的嵌套

<LinearLayoutxmlns: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/bj"
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"
android:gravity="center"
android:orientation="horizontal">

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

<RadioButton
android:id="@+id/scissor"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/scissor"/>

<RadioButton
android:id="@+id/stone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/stone"/>

<RadioButton
android:id="@+id/cloth"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/cloth"/>
</RadioGroup>
</LinearLayout>

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

<Button
android:id="@+id/Game"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="@string/chuanquan"/>
</LinearLayout>

</LinearLayout>

2、布局设计_SecondActivity

<LinearLayoutxmlns: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/bj"
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=".SecondActivity">

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

<TextView
android:id="@+id/txtPerson"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/NULL"
android:textSize="20sp"/>
<TextView
android:id="@+id/txtComputer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/NULL"
android:textSize="20sp"/>

</LinearLayout>

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

<TextView
android:id="@+id/txtWinner"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/NULL"
android:textSize="20sp"/>
</LinearLayout>

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

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

</LinearLayout>

实现类：

电脑类：

packagecom.bzu.Random_Game.Model;

publicclassComputer{

publicstaticStringstr;
publicstaticStringComputer_Game(intrandomNumber){

//Math.random();//返回0.0-1.0

switch(randomNumber){
case1:
str="剪刀";
break;
case2:
str="石头";
break;
case3:
str="布";
break;
}
returnstr;

}

}

packagecom.bzu.Random_Game.Model;

publicclassPerson{
publicstaticStringstrText;
/*publicstaticStringscissorText;//用户选择剪刀
publicstaticStringstoneText;//用户选择石头
publicstaticStringclothText;//用户选择布
*/
publicstaticStringPerson_Game(Stringstr){

if(str.equals("剪刀"))
{
strText="剪刀";
}
if(str.equals("石头"))
{
strText="石头";
}
if(str.equals("布"))
{
strText="布";
}

returnstrText;
}

}

packagecom.bzu.Random_Game.Model;

publicclassGame{

publicstaticStringResult;

publicstaticStringPersonComputer_Game(StringP_str,intCom_ranNumber){

Stringp_result=Person.Person_Game(P_str);
Stringc_result=Computer.Computer_Game(Com_ranNumber);

if(((p_result.equals("剪刀"))&&(c_result.equals("布")))
||((p_result.equals("布"))&&(c_result.equals("石头")))
||((p_result.equals("石头"))&&(c_result.equals("剪刀")))){//剪刀>布，石头>剪刀，布>石头
Result="玩家赢";
}elseif(p_result.equals(c_result)){//剪刀->剪刀,石头->石头布->布
Result="平局";
}else{
Result="电脑赢";
}

returnResult;
}
}

运行结果：
