先来说说2048游戏规则：

开始时棋盘内随机出现两个数字，出现的数字仅可能为2或4

玩家可以选择上下左右四个方向，若棋盘内的数字出现位移或合并，视为有效移动

玩家选择的方向上若有相同的数字则合并，每次有效移动可以同时合并，但不可以连续合并

合并所得的所有新生成数字想加即为该步的有效得分

玩家选择的方向行或列前方有空格则出现位移

每有效移动一步，棋盘的空位(无数字处)随机出现一个数字(依然可能为2或4)

棋盘被数字填满，无法进行有效移动，判负，游戏结束

棋盘上出现2048，判胜，游戏结束

下面代码

MainActivity类

public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(new GameView(this)); } }

定义一个卡片类显示数据

/卡片类型 public class Card extends FrameLayout { //2 TextView tv; private int number = 0; int width; public Card(Context context, int width) { super(context); this.width = width; init(); } private void init() { tv = new TextView(getContext()); setPadding(5, 5, 5, 5); FrameLayout.LayoutParams lp = new LayoutParams(width - 10, width - 10); tv.setLayoutParams(lp); tv.setGravity(Gravity.CENTER); tv.setTextColor(Color.WHITE); tv.setTextSize(48); this.addView(tv); setColor(); } public void setNumber(int number) { this.number = number; if (number == 0) tv.setText(""); else tv.setText(number + ""); setColor(); } @Override public String toString() { return "Card{" + "tv=" + tv + ", number=" + number + ", width=" + width + '}'; } private void setColor() { switch (number) { case 0: tv.setBackgroundColor(getResources().getColor(R.color.c0)); break; case 2: tv.setBackgroundColor(getResources().getColor(R.color.c2)); break; case 4: tv.setBackgroundColor(getResources().getColor(R.color.c4)); break; case 8: tv.setBackgroundColor(getResources().getColor(R.color.c8)); break; case 16: tv.setBackgroundColor(getResources().getColor(R.color.c16)); break; case 32: tv.setBackgroundColor(getResources().getColor(R.color.c32)); break; case 64: tv.setBackgroundColor(getResources().getColor(R.color.c64)); break; case 128: tv.setBackgroundColor(getResources().getColor(R.color.c128)); break; case 256: tv.setBackgroundColor(getResources().getColor(R.color.c256)); break; case 512: tv.setBackgroundColor(getResources().getColor(R.color.c512)); break; case 1024: tv.setBackgroundColor(getResources().getColor(R.color.c1024)); break; case 2048: tv.setBackgroundColor(getResources().getColor(R.color.c2048)); break; } } public int getNumber() { return number; } }

自己定义一下上面的几种颜色 在values下的colors中

<"1.0" encoding="utf-8"?> <resources> <color name="colorPrimary">#3F51B5</color> <color name="colorPrimaryDark">#303F9F</color> <color name="colorAccent">#FF4081</color> <color name="c0">#43382a</color> <color name="c2">#2a8618</color> <color name="c4">#3d6319</color> <color name="c8">#F2B179</color> <color name="c16">#F59563</color> <color name="c32">#F57C5F</color> <color name="c64">#5b69b7</color> <color name="c128">#b37d3e</color> <color name="c256">#3a9096</color> <color name="c512">#d7882c</color> <color name="c1024">#5c1b78</color> <color name="c2048">#640548</color> </resources>

布局类 和里面的运算方法

public class GameView extends GridLayout { int[][] values = new int[4][4]; Card[][] cards = new Card[4][4]; // Integer -128-127 == 大于这个数 两个对象 public GameView(Context context) { super(context); init();
