最近有一个私活是要做一个像XLS的表，然后里面可能还有一些算法和逻辑，网上找了点资料看了一些别人的代码，呈现给大家看，希望项目中用到的话可以派上用场。
先上图:
初始化的状态 
输入内容计算结果
添加行
初始化
表单属性：
Dict.java
public class Dict {
private int id;
private String name;
private int number;
private float price;
private float totle;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
public float getPrice() {
return price;
}
public void setPrice(float price) {
this.price = price;
}
public float getTotle() {
return totle;
}
public void setTotle(float totle) {
this.totle = totle;
}
}
填充数据DictDaoImpl
public class DictDaoImpl {
public DictDaoImpl(Context context) {
}
public boolean isExist() {
return false;
}
public List<Dict> getDictItem(String dictId) {
String[] dicts = new String[5];
List<Dict> retList = new ArrayList<Dict>();
for (int j = 0; j < dicts.length; j++) {
Dict dict = new Dict();
dict.setName(dicts[j]);
dict.setId(j+1);
// dict.setOrders(j);
// dict.setTypes(1000);
retList.add(dict);
}
return retList;
}
public long insert(Dict entity) {
return 1L;
}
public void delete(int id) {
}
public void update(Dict entity) {
}
public Dict get(Object id) {
Dict dict = new Dict();
// dict.setId(1);
// dict.setName("华东");
// dict.setOrders(1);
// dict.setTypes(1000);
return dict;
}
public void delete(Integer... ids) {
}
}主要实现的Activity
