Android编写2048小游戏
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
publicclassMainActivityextendsAppCompatActivity{
@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(newGameView(this));
}
}
定义一个卡片类显示数据
/卡片类型
publicclassCardextendsFrameLayout{
//2
TextViewtv;
privateintnumber=0;
intwidth;
publicCard(Contextcontext,intwidth){
super(context);
this.width=width;
init();
}
privatevoidinit(){
tv=newTextView(getContext());
setPadding(5,5,5,5);
FrameLayout.LayoutParamslp=newLayoutParams(width-10,width-10);
tv.setLayoutParams(lp);
tv.setGravity(Gravity.CENTER);
tv.setTextColor(Color.WHITE);
tv.setTextSize(48);
this.addView(tv);
setColor();
}
publicvoidsetNumber(intnumber){
this.number=number;
if(number==0)
tv.setText("");
else
tv.setText(number+"");
setColor();
}
@Override
publicStringtoString(){
return"Card{"+
"tv="+tv+
",number="+number+
",width="+width+
'}';
}
privatevoidsetColor(){
switch(number){
case0:
tv.setBackgroundColor(getResources().getColor(R.color.c0));
break;
case2:
tv.setBackgroundColor(getResources().getColor(R.color.c2));
break;
case4:
tv.setBackgroundColor(getResources().getColor(R.color.c4));
break;
case8:
tv.setBackgroundColor(getResources().getColor(R.color.c8));
break;
case16:
tv.setBackgroundColor(getResources().getColor(R.color.c16));
break;
case32:
tv.setBackgroundColor(getResources().getColor(R.color.c32));
break;
case64:
tv.setBackgroundColor(getResources().getColor(R.color.c64));
break;
case128:
tv.setBackgroundColor(getResources().getColor(R.color.c128));
break;
case256:
tv.setBackgroundColor(getResources().getColor(R.color.c256));
break;
case512:
tv.setBackgroundColor(getResources().getColor(R.color.c512));
break;
case1024:
tv.setBackgroundColor(getResources().getColor(R.color.c1024));
break;
case2048:
tv.setBackgroundColor(getResources().getColor(R.color.c2048));
break;
}
}
publicintgetNumber(){
returnnumber;
}
}
自己定义一下上面的几种颜色在values下的colors中
<?xmlversion="1.0"encoding="utf-8"?> <resources> <colorname="colorPrimary">#3F51B5</color> <colorname="colorPrimaryDark">#303F9F</color> <colorname="colorAccent">#FF4081</color> <colorname="c0">#43382a</color> <colorname="c2">#2a8618</color> <colorname="c4">#3d6319</color> <colorname="c8">#F2B179</color> <colorname="c16">#F59563</color> <colorname="c32">#F57C5F</color> <colorname="c64">#5b69b7</color> <colorname="c128">#b37d3e</color> <colorname="c256">#3a9096</color> <colorname="c512">#d7882c</color> <colorname="c1024">#5c1b78</color> <colorname="c2048">#640548</color> </resources>
