本人对游戏这一块很有兴趣，刚好 又兼着学安卓，所以就学着做了下安卓的 游戏

本文章是自己学习和记录用，喜欢的人可以阅读，写的不好的勿喷
开始，安卓基本的东西和环境的搭建就不细说了，先进行游戏的基本分析：
需要的元素：钱 钱袋 画板
小游戏，仅仅是机能的一些测试，所以没有做的很好，
个人喜欢做游戏的原因就是因为游戏和现实的世界非常的贴近，能够用现实的想法去思考游戏
比如本游戏：首先，钱肯定是默认的情况下就不停的运动的，然后钱袋，由玩家去控制，也能进行移动，当钱和钱袋接触，进行加分，并且钱消失，就是这么一段简单的想法
主Activity
package com.rp;import android.app.Activity;import android.os.Bundle;import android.view.Window;import android.view.WindowManager;public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //设置全屏 this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); requestWindowFeature(Window.FEATURE_NO_TITLE); //显示自定义的SurfaceView视图 setContentView(new MySurfaceView(this)); }} 钱这个类
package com.rp;import android.graphics.Canvas;import android.graphics.Paint;import android.graphics.Rect;public class Money { //定义钱币 private Rect money; public int moneyX=0,moneyY=0; //钱包的坐标 public int speed=2;//钱币的下落速度 public int height; private boolean isdeath=false; private int cnt;//分数 public Money(int moneyX,int speed,int height){ this.moneyX = moneyX; this.speed = speed; this.height = height; this.cnt = speed; } public void DrawMoney(Canvas canvas,Paint paint){ money = new Rect(moneyX, moneyY, moneyX+10, moneyY+20); canvas.drawRect(money, paint); } //钱的逻辑 /*** * 自由下落 当过界的时候重新运动 */ public void logic(){ if(isdeath()){ moneyY =0; }else{ moneyY +=speed; } } /*** * 死亡函数 * 当钱过界，或者遇到钱袋即死亡 */ public boolean isdeath(){ if(this.moneyY>=this.height){ isdeath = true; }else{ isdeath = false; } return isdeath; } public int getCnt() { return cnt; } public void setCnt(int cnt) { this.cnt = cnt; } } 这里加入了一个摇杆系统，没特别作用，好看罢了
