话不多说，直接开撸！
刚开始进入Splash界面：
1.SplashActivity.java(两秒后进入开始界面，Splash界面的布局只有一个图片，在博客后，会展示给大家看)

public class SplashActivity extends Activity {
    
    

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);

        new Thread(new Runnable() {     
            @Override
            public void run() {
                try {
                    Thread.sleep(2000);
                    Intent intent=new Intent(SplashActivity.this, LoginActivity.class);
                    startActivity(intent);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                finish();
            }
        }).start();
    }
}

2.LoginActivity（登陆界面）

   private Button btn1,btn2;
   private EditText etAcount,etPassword;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        initView();
    }
    private void initView() {
        btn1=(Button) findViewById(R.id.btn_login);
        btn2=(Button) findViewById(R.id.btn_register);

        etAcount=(EditText) findViewById(R.id.et_account);
        etPassword=(EditText) findViewById(R.id.et_pwd);
        btn1.setOnClickListener(new OnClickListener() {
            //登录按钮的监听
            @Override
            public void onClick(View v) {
                SharedPreferences sharedPreferences=getSharedPreferences("user", MODE_PRIVATE);
                String number=sharedPreferences.getString("number", "");
                int a,b;
                if (number=="") {
                    a=0;//记录用户个数
                }else {
                    a=Integer.parseInt(number);
                }
                String account;
                String password;
                for (b=0;b<a;b++) {
    
    
                    account="account"+b;
                    password="password"+b;
                    String jname=sharedPreferences.getString(account,"");
                    String jpwd=sharedPreferences.getString(password, "");

                    if (jname.equals(etAcount.getText().toString())||jpwd.equals(etPassword.getText().toString())) {
                         if (jname.equals(etAcount.getText().toString())&&jpwd.equals(etPassword.getText().toString())) {
                             finish();
                             Intent intent=new Intent(LoginActivity.this, MainActivity.class);
                             startActivity(intent);
                             break;
                         }else if (jname.equals(etAcount.getText().toString())) {
                            Toast.makeText(LoginActivity.this, "密码错误", Toast.LENGTH_SHORT).show();  
                        }
                    }
                }
                if (b==a) {
                    Toast.makeText(LoginActivity.this, "用户未注册", Toast.LENGTH_SHORT).show();
                }
            }
        });
        //注册按钮的监听
        btn2.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                String account;
                String password;
                SharedPreferences sharedPreferences=getSharedPreferences("user",MODE_PRIVATE);
                String number=sharedPreferences.getString("number", "");
                int a;
                int b;
                if (number=="") {
                    a=0;
                }else {
                    a=Integer.parseInt(number);
                }
                for (b = 0; b <a; b++) {
    
    
                    account="account"+b;
                    password="password"+b;
                    String jname=sharedPreferences.getString(account,"");
                    if (jname.equals(etAcount.getText().toString())) {
                        break;
                    }
                }
                if (b==a) {
                    if (etAcount.getText().toString().equals("")&&etPassword.getText().toString().equals("")) {
                        Toast.makeText(LoginActivity.this,"用户名密码不能为空", Toast.LENGTH_SHORT).show();
                    }else {
                        account="account"+b;
                        password="password"+b;
                        a++;
                        SharedPreferences.Editor editor=sharedPreferences.edit();
                        editor.putString(account,etAcount.getText().toString());
                        editor.putString(password,etPassword.getText().toString());
                        editor.putString("number",a+"");
                        editor.commit();
                        Toast.makeText(LoginActivity.this,"注册成功", Toast.LENGTH_SHORT).show();
                    }
                }else {
                    Toast.makeText(LoginActivity.this,"该账户已存在", Toast.LENGTH_SHORT).show();
                }
            }
        });
    }   
}

LoginActivity的布局如下：

    <ImageView
        android:id="@+id/img_head"
        android:layout_width="match_parent"
        android:layout_height="260dp"

    <EditText   
        android:id="@+id/et_account"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_below="@id/img_head"
        android:layout_marginLeft="50dp"
        android:layout_marginRight="50dp"
        android:layout_marginTop="40dp"
        android:background="@drawable/set_charge_top"
        android:drawableLeft="@drawable/login_img2"
        android:hint="请输入账号" />

        <EditText

            android:layout_marginTop="10dp"
            android:layout_marginRight="50dp"
            android:background="@drawable/set_charge_top"
            android:drawableLeft="@drawable/login_img3"
            android:hint="请输入密码" />
     <Button 
         android:id="@+id/btn_login"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"

         android:layout_marginTop="10dp"
         android:layout_marginLeft="60dp"/>

4.Card.java(卡片类)

public class Card extends FrameLayout {
    
    
    private int num=0;
    private TextView label;
    public Card(Context context) {
        super(context);
        label=new TextView(getContext());   
        label.setTextSize(32);
        label.setGravity(Gravity.CENTER);

        label.setBackgroundColor(0x33ffffff);//设置每个卡片的颜色

        LayoutParams lp=new LayoutParams(-1,-1);//该类用来初始化layout控件textView里的宽高属性
        lp.setMargins(10, 10, 0, 0);//设置间隔
        addView(label,lp);           
        setNum(0);
    }

    public int getNum() {
        return num;
    }
    public void setNum(int num) {   
        this.num=num;
        if (num<=0) {
            label.setText("");
        }else {
            label.setText(num+"");
        }
    }
    //重写equals方法，判断卡片绑定的数字是否相等
    public boolean equals(Card o) {
        return getNum()==o.getNum();
    }  
}

5.GameView.java(主要逻辑)

public class GameView extends GridLayout {
    
    
    private Card[][] cardsMap = new Card[4][4];
    //用来存放cardsMap下标用的Point类的集合
    private List<Point> emptyPoints = new ArrayList<Point>();

    public GameView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        initGameView();
    }

    public GameView(Context context) {
        super(context);
        initGameView();
    }

    public GameView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initGameView();
    }

    private void initGameView() {
        setColumnCount(4);
        setBackgroundColor(0xffddada0);

        setOnTouchListener(new OnTouchListener() {
            // 添加触摸事件 开始
            private float startX, startY, offsetX, offsetY;

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    startX = event.getX();
                    startY = event.getY();
                    break;
                case MotionEvent.ACTION_UP:
                    offsetX = event.getX() - startX;// 大于0则代表向右滑
                    offsetY = event.getY() - startY;// 小于0代表向上滑

                    if (Math.abs(offsetX) > Math.abs(offsetY)) {
                        if (offsetX > 5) {
                            swipeRight();
                        } else if (offsetX < -5) {
                            swipeLeft();
                        }
                    } else {
                        if (offsetY > 5) {
                            swipeDown();
                        } else if (offsetY < -5) {
                            swipeUp();
                        }
                    }
                    break;
                }
                return true;
            }
        });
    }
    //根据卡片宽和高
    @Override
    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
        //该方法就是宽高发生改变的时候我们可以得到当前的宽高是多少

6.最后不要忘记在清单配置文件中配置信息

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.jerry.game2048"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="17"
        android:targetSdkVersion="21" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/game2048"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.jerry.game2048.MainActivity"
            android:label="@string/app_name"
            //设置屏幕为竖屏
             android:screenOrientation="portrait" >
        </activity>
        <activity
            android:name=".SplashActivity"
            android:label="@string/title_activity_splash" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".LoginActivity"
            android:label="@string/title_activity_login" >
        </activity>
    </application>
</manifest>

7.其中的窜天猴的动画效果实现如下：

  1. 在res文件下新建一个anim文件夹

  2. 在anim文件夹下新建一个anim_monky.xml的布局文件

    anim_monky.xml
