1.首先编写敌人，主角，子d 3个类

package com.example.myapplication10.entity;import com.example.myapplication10.R;//敌人public class DiRenEntity {    public float x;    public float y;    public int image_src = R.drawable.diren;}

package com.example.myapplication10.entity;import com.example.myapplication10.R;//主角public class ZhuJueEntity {    public float x;    public float y;    public int image_src = R.drawable.zhujue;}

package com.example.myapplication10.entity;import com.example.myapplication10.R;;//子dpublic class ZIDanEntity {    public float x;    public float y;    public int image_src = R.drawable.zIDan;}

2.自定义页面.java
