CardGame猜牌小游戏

CardGame

新建项目CardGame

一直下一步完成创建工程。

 

首先新建一个drawable文件夹，将55张扑克牌放入文件夹中。

而后新建一个工具包：

创建一个工具类：Tools（在Tools中提供一些公共的静态方法供外部调用）

创建玩Tools工具类后，需要在string.xml中定义每一张扑克牌的名称：

<stringname="p_1">大王</string>     <stringname="p_2">小王</string>     <stringname="p_b1">背面</string>         <stringname="p_x_1">红心A</string>     <stringname="p_x_2">红心2</string>     <stringname="p_x_3">红心3</string>     <stringname="p_x_4">红心4</string>     <stringname="p_x_5">红心5</string>     <stringname="p_x_6">红心6</string>     <stringname="p_x_7">红心7</string>     <stringname="p_x_8">红心8</string>     <stringname="p_x_9">红心9</string>     <stringname="p_x_10">红心10</string>     <stringname="p_x_J">红心J</string>     <stringname="p_x_Q">红心Q</string>     <stringname="p_x_K">红心K</string>         <stringname="p_f_1">方块A</string>     <stringname="p_f_2">方块2</string>     <stringname="p_f_3">方块3</string>     <stringname="p_f_4">方块4</string>     <stringname="p_f_5">方块5</string>     <stringname="p_f_6">方块6</string>     <stringname="p_f_7">方块7</string>     <stringname="p_f_8">方块8</string>     <stringname="p_f_9">方块9</string>     <stringname="p_f_10">方块10</string>     <stringname="p_f_J">方块J</string>     <stringname="p_f_Q">方块Q</string>     <stringname="p_f_K">方块K</string>       <stringname="p_h_1">黑桃A</string>     <stringname="p_h_2">黑桃2</string>     <stringname="p_h_3">黑桃3</string>     <stringname="p_h_4">黑桃4</string>     <stringname="p_h_5">黑桃5</string>     <stringname="p_h_6">黑桃6</string>     <stringname="p_h_7">黑桃7</string>     <stringname="p_h_8">黑桃8</string>     <stringname="p_h_9">黑桃9</string>     <stringname="p_h_10">黑桃10</string>     <stringname="p_h_J">黑桃J</string>     <stringname="p_h_Q">黑桃Q</string>     <stringname="p_h_K">黑桃K</string>         <stringname="p_m_1">梅花A</string>     <stringname="p_m_2">梅花2</string>     <stringname="p_m_3">梅花3</string>     <stringname="p_m_4">梅花4</string>     <stringname="p_m_5">梅花5</string>     <stringname="p_m_6">梅花6</string>     <stringname="p_m_7">梅花7</string>     <stringname="p_m_8">梅花8</string>     <stringname="p_m_9">梅花9</string>     <stringname="p_m_10">梅花10</string>     <stringname="p_m_J">梅花J</string>     <stringname="p_m_Q">梅花Q</string>     <stringname="p_m_K">梅花K</string>

首先在Tools类中创建一个方法public
static StringgetCardName(Context mContext, String fileName),将文件名（图片的名称）传入，返回我们可以认得的扑克牌（string.xml中定义的扑克牌名称）。

public static String getCardName(Context mContext, String fileName) {        Context context = mContext.getApplicationContext();        String result = "null";        switch (fileName) {        case "p_1": // 大王            result = context.getString(R.string.p_1);            break;        case "p_2": // 小王            result = context.getString(R.string.p_2);            break;        case "p_x_1": // 红心A            result = context.getString(R.string.p_x_1);            break;        case "p_x_2": // 红心2            result = context.getString(R.string.p_x_2);            break;        case "p_x_3": // 红心3            result = context.getString(R.string.p_x_3);            break;        case "p_x_4": // 红心4            result = context.getString(R.string.p_x_4);            break;        case "p_x_5": // 红心5            result = context.getString(R.string.p_x_5);            break;        case "p_x_6": // 红心6            result = context.getString(R.string.p_x_6);            break;        case "p_x_7": // 红心7            result = context.getString(R.string.p_x_7);            break;        case "p_x_8": // 红心8            result = context.getString(R.string.p_x_8);            break;        case "p_x_9": // 红心9            result = context.getString(R.string.p_x_9);            break;        case "p_x_10": // 红心10            result = context.getString(R.string.p_x_10);            break;        case "p_x_11": // 红心J            result = context.getString(R.string.p_x_J);            break;        case "p_x_12": // 红心Q            result = context.getString(R.string.p_x_Q);            break;        case "p_x_13": // 红心K            result = context.getString(R.string.p_x_K);            break;          case "p_h_1": // 黑桃A            result = context.getString(R.string.p_h_1);            break;        case "p_h_2": // 黑桃2            result = context.getString(R.string.p_h_2);            break;        case "p_h_3": // 黑桃3            result = context.getString(R.string.p_h_3);            break;        case "p_h_4": // 黑桃4            result = context.getString(R.string.p_h_4);            break;        case "p_h_5": // 黑桃5            result = context.getString(R.string.p_h_5);            break;        case "p_h_6": // 黑桃6            result = context.getString(R.string.p_h_6);            break;        case "p_h_7": // 黑桃7            result = context.getString(R.string.p_h_7);            break;        case "p_h_8": // 黑桃8            result = context.getString(R.string.p_h_8);            break;        case "p_h_9": // 黑桃9            result = context.getString(R.string.p_h_9);            break;        case "p_h_10": // 黑桃10            result = context.getString(R.string.p_h_10);            break;        case "p_h_11": // 黑桃J            result = context.getString(R.string.p_h_J);            break;        case "p_h_12": // 黑桃Q            result = context.getString(R.string.p_h_Q);            break;        case "p_h_13": // 黑桃K            result = context.getString(R.string.p_h_K);            break;          case "p_m_1": // 梅花A            result = context.getString(R.string.p_m_1);            break;        case "p_m_2": // 梅花2            result = context.getString(R.string.p_m_2);            break;        case "p_m_3": // 梅花3            result = context.getString(R.string.p_m_3);            break;        case "p_m_4": // 梅花4            result = context.getString(R.string.p_m_4);            break;        case "p_m_5": // 梅花5            result = context.getString(R.string.p_m_5);            break;        case "p_m_6": // 梅花6            result = context.getString(R.string.p_m_6);            break;        case "p_m_7": // 梅花7            result = context.getString(R.string.p_m_7);            break;        case "p_m_8": // 梅花8            result = context.getString(R.string.p_m_8);            break;        case "p_m_9": // 梅花9            result = context.getString(R.string.p_m_9);            break;        case "p_m_10": // 梅花10            result = context.getString(R.string.p_m_10);            break;        case "p_m_11": // 梅花J            result = context.getString(R.string.p_m_J);            break;        case "p_m_12": // 梅花Q            result = context.getString(R.string.p_m_Q);            break;        case "p_m_13": // 梅花K            result = context.getString(R.string.p_m_K);            break;          case "p_f_1": // 方块A            result = context.getString(R.string.p_f_1);            break;        case "p_f_2": // 方块2            result = context.getString(R.string.p_f_2);            break;        case "p_f_3": // 方块3            result = context.getString(R.string.p_f_3);            break;        case "p_f_4": // 方块4            result = context.getString(R.string.p_f_4);            break;        case "p_f_5": // 方块5            result = context.getString(R.string.p_f_5);            break;        case "p_f_6": // 方块6            result = context.getString(R.string.p_f_6);            break;        case "p_f_7": // 方块7            result = context.getString(R.string.p_f_7);            break;        case "p_f_8": // 方块8            result = context.getString(R.string.p_f_8);            break;        case "p_f_9": // 方块9            result = context.getString(R.string.p_f_9);            break;        case "p_f_10": // 方块10            result = context.getString(R.string.p_f_10);            break;        case "p_f_11": // 方块J            result = context.getString(R.string.p_f_J);            break;        case "p_f_12": // 方块Q            result = context.getString(R.string.p_f_Q);            break;        case "p_f_13": // 方块K            result = context.getString(R.string.p_f_K);            break;        default:            result = "error";            break;        }        return result;     }

而后在Tools继续添加一个通过id查找fileName的方法：

publicstaticString getFileNameById(Context mContext,int id)

public static String getFileNameById(Context mContext, int id) {        Context context = mContext.getApplicationContext();        String result = context.getResources().getResourceEntryName(id);        return result;     }

而后在Tools继续添加一个通过fileName查找id的方法：

publicstaticintgetIdByFileName(Context mContext, String fileName)

public static int getIdByFileName(Context mContext, String fileName) {        Context context = mContext.getApplicationContext();        int result = context.getResources().getIdentifier(fileName,               "drawable", mContext.getPackageName());        return result;     }

接下来就是MainActivity的布局文件activity_main.xml，这里将根布局设置为LinearLayout，并添加一个Button。

<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="#FFFFFFCC"     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">       <Button         android:id="@+id/single_card_mode"         style="@android:style/Widget.Button.Inset"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:onClick="onClick"         android:text="@string/single_card"/>   </LinearLayout>

之后在MainActivity类中删除不必要的代码，并添加一个onClick(View view)方法

package lyx.feng.cardgame;   import android.app.Activity; import android.os.Bundle; import android.view.View;   public class MainActivity extends Activity {       @Override     protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);     }       public void onClick(View view) {        switch (view.getId()) {        case R.id.single_card_mode:              break;        }     } }

之后创建一个继承Activity的SingleCardModeActivity类，并添加布局文件：singlecardmode.xml

首先在singlecardmode.xml布局文件中添加一个Spinner、Button、ImageView这3个组件。

<?xmlversion="1.0"encoding="utf-8"?> <LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="#FFFFFFCC"     android:orientation="vertical">       <LinearLayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="horizontal">           <Spinner             android:id="@+id/singlecardmode_spinner"             android:layout_width="0dp"             android:layout_height="wrap_content"             android:layout_weight="1"/>           <Button             android:id="@+id/singlecardmode_btn"             style="@android:style/Widget.Button.Inset"             android:layout_width="0dp"             android:layout_height="wrap_content"             android:layout_margin="10dp"             android:layout_weight="1"             android:text="@string/showresult"/>     </LinearLayout>       <ImageView         android:id="@+id/singlecardmode_imageview"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:layout_margin="12dp"         android:gravity="center_horizontal"         android:src="@drawable/p_b1"/>   </LinearLayout>

布局都比较简单，上面一个水平方向的LinearLayout，里面包裹的是Spinner和一个Button，下面则直接显示一个ImageView。

接着就是SingleCardModeActivity这个类。

import lyx.feng.cardgame.R; import android.app.Activity; import android.os.Bundle;   public class SingleCardModeActivityextends Activity {       @Override     protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        super.setContentView(R.layout.singlecardmode);     } }

在MainActivity类的onClick()方法中添加跳转的操作

public void onClick(View view) {        switch (view.getId()) {        case R.id.single_card_mode:            startActivity(new Intent(this, SingleCardModeActivity.class));            break;        }     }

并在AndroidManifest.xml文件注册SingleCardModeActivity。

<activityandroid:name=".SingleCardModeActivity"/>

接下来运行程序：

主界面：

点击单张猜牌按钮：

接下来就是修改SingleCardModeActivity代码：

这里首先获取singlecardmodeactivity.xml布局的Spinner、Button、ImageView这3个组件。

package lyx.feng.cardgame; ...... public class SingleCardModeActivity extends Activity {     private ImageViewimageView = null;     private Spinnerspinner = null;     private Buttonbtn = null;       @Override     protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        super.setContentView(R.layout.singlecardmode);           init();     }       private void init() {           this.imageView = (ImageView)super               .findViewById(R.id.singlecardmode_imageview);        this.spinner = (Spinner)super               .findViewById(R.id.singlecardmode_spinner);        this.btn = (Button)super.findViewById(R.id.singlecardmode_btn);     } }

接下来为Spinner初始化操作：在操作之前，先在strings.xml文件中添加一个数组，里面保存的是扑克牌的集合。

<string-arrayname="allCards">         <item>大王</item>         <item>小王</item>         <item>红桃A</item>         <item>红桃1</item>         <item>红桃2</item>         <item>红桃3</item>         <item>红桃4</item>         <item>红桃5</item>         <item>红桃6</item>         <item>红桃7</item>         <item>红桃8</item>         <item>红桃9</item>         <item>红桃10</item>         <item>红桃J</item>         <item>红桃Q</item>         <item>红桃K</item>                 <item>黑桃A</item>         <item>黑桃1</item>         <item>黑桃2</item>         <item>黑桃3</item>         <item>黑桃4</item>         <item>黑桃5</item>         <item>黑桃6</item>         <item>黑桃7</item>         <item>黑桃8</item>         <item>黑桃9</item>         <item>黑桃10</item>         <item>黑桃J</item>         <item>黑桃Q</item>         <item>黑桃K</item>                 <item>方块A</item>         <item>方块1</item>         <item>方块2</item>         <item>方块3</item>         <item>方块4</item>         <item>方块5</item>         <item>方块6</item>         <item>方块7</item>         <item>方块8</item>         <item>方块9</item>         <item>方块10</item>         <item>方块J</item>         <item>方块Q</item>         <item>方块K</item>                 <item>梅花A</item>         <item>梅花1</item>         <item>梅花2</item>         <item>梅花3</item>         <item>梅花4</item>         <item>梅花5</item>         <item>梅花6</item>         <item>梅花7</item>         <item>梅花8</item>         <item>梅花9</item>         <item>梅花10</item>         <item>梅花J</item>         <item>梅花Q</item>         <item>梅花K</item>     </string-array>

 

而后是Spinner的初始化：

String allCards[] = getResources().getStringArray(R.array.allCards);         ArrayAdapter<String> adapter = new ArrayAdapter<>(this,               android.R.layout.simple_spinner_dropdown_item, allCards);        this.spinner.setAdapter(adapter);         this.spinner.setOnItemSelectedListener(new OnItemSelectedListener() {              @Override            public void onItemSelected(AdapterView<?> parent, View view,                   int position,long id) {               imageView.setImageResource(R.drawable.cardbackground);            }              @Override            public void onNothingSelected(AdapterView<?> parent) {               // TODO Auto-generated method stub              }        });

效果：

而后是在54张牌中随机获取一张牌设置到ImageView中去。这里添加一个getRandomCard（）方法随机获取一张扑克牌，返回一个id。

public int getRandomCard() {        List<Integer> list = Tools.getAllCards("p_");        int id = list.get(new Random().nextInt(list.size()));        return id;     }

Tools.getAllCards方法返回所有扑克牌的集合。

public static List<Integer> getAllCards(String startWith) {        List<Integer> list = new ArrayList<Integer>();        Field fields[] = R.drawable.class.getDeclaredFields();        for (int i = 0; i < fields.length; i++) {            if (fields[i].getName().startsWith(startWith)) {               try {                   list.add(fields[i].getInt(R.drawable.class));               } catch (Exception e) {                   e.printStackTrace();               }            }        }        return list;     }

接着就是SingleCardModeActivity类的Button按钮操作。

this.btn.setOnClickListener(new OnClickListener() {              @Override            public void onClick(View v) {                 // 随机获取的一张扑克牌Id               int randomCard = getRandomCard();               // Spinner选择的内容               String temp = spinner.getSelectedItem().toString();               // Spinner选择的位置               intselectItem = spinner.getSelectedItemPosition();               // 显示的卡片名称               String selectCardName = Tools.getCardName(                      SingleCardModeActivity.this, Tools.getFileNameById(                             SingleCardModeActivity.this, randomCard));                 imageView.setImageResource(randomCard);               if (temp.equals(selectCardName)) {                   Toast.makeText(SingleCardModeActivity.this,"猜对了",                          Toast.LENGTH_SHORT).show();               } else {                   Toast.makeText(SingleCardModeActivity.this,                          "你选择的是：" + temp +"\n显示的是：" + selectCardName,                          Toast.LENGTH_SHORT).show();               }            }        });

在Button按钮获取了选择的卡片和显示的卡片，然后对比显示对应的Toast提示内容。

在SingleCardModeActivity类新建2个Animation，一个显示ImageView进来的动画，一个显示ImageView出去的动画

public Animation getAlphaAnimation() {        AlphaAnimation alpha = new AlphaAnimation(0.0f, 1.0f);        alpha.setDuration(500);        return alpha;     }       public Animation getInTransAnimation() {        int height = getWindowManager().getDefaultDisplay().getHeight();        int width = getWindowManager().getDefaultDisplay().getWidth();        TranslateAnimation trans = new TranslateAnimation(width, 0, 0, 0);        trans.setDuration(500);        return trans;     }

而后在相应的位置设置即可。

最后效果：
