編輯：關於Android編程
先來說說2048游戲規則：
開始時棋盤內隨機出現兩個數字，出現的數字僅可能為2或4
玩家可以選擇上下左右四個方向，若棋盤內的數字出現位移或合並，視為有效移動
玩家選擇的方向上若有相同的數字則合並，每次有效移動可以同時合並，但不可以連續合並
合並所得的所有新生成數字想加即為該步的有效得分
玩家選擇的方向行或列前方有空格則出現位移
每有效移動一步，棋盤的空位(無數字處)隨機出現一個數字(依然可能為2或4)
棋盤被數字填滿，無法進行有效移動，判負，游戲結束
棋盤上出現2048，判勝，游戲結束
下面代碼
MainActivity類
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new GameView(this));
}
}
定義一個卡片類顯示數據
/卡片類型
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();
}

setPadding(5, 5, 5, 5);

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 +

}

自己定義一下上面的幾種顏色 在values下的colors中
<?xml version="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>
