android 酷欧天气完整项目

  先要建议三张表：province、city、county，分别用于存放省市县的数据信息。

Province.java

package com.example.lenovo.coolweather.db;import org.litepal.crud.DataSupport;/*** 代表省的数据库表*/public class Province extends DataSupport {private int id;    //id号private String provinceName;  //省得名字private int provinceCode;    //省得代号public int getId() {return id;}public void setId(int id) {this.id = id;}public String getProvinceName() {return provinceName;}public void setProvinceName(String provinceName) {this.provinceName = provinceName;}public int getProvinceCode() {return provinceCode;}public void setProvinceCode(int provinceCode) {this.provinceCode = provinceCode;}
}

City.java

package com.example.lenovo.coolweather.db;import org.litepal.crud.DataSupport;/*** 代表市的数据库表*/public class City extends DataSupport {private int id;private String cityName;  //城市名字private int cityCode;   //城市代号private int provinceId;   //当前城市所属省得idpublic int getId() {return id;}public void setId(int id) {this.id = id;}public String getCityName() {return cityName;}public void setCityName(String cityName) {this.cityName = cityName;}public int getCityCode() {return cityCode;}public void setCityCode(int cityCode) {this.cityCode = cityCode;}public int getProvinceId() {return provinceId;}public void setProvinceId(int provinceId) {this.provinceId = provinceId;}
}

package com.example.lenovo.coolweather.db;import org.litepal.crud.DataSupport;/*** 代表县的数据库表*/public class County extends DataSupport {private int id;private String countName;  //县的名字private String weatherId;   //天气idprivate int cityId;    //当前县所属城市的idpublic int getId() {return id;}public void setId(int id) {this.id = id;}public String getCountName() {return countName;}public void setCountName(String countName) {this.countName = countName;}public String getWeatherId() {return weatherId;}public void setWeatherId(String weatherId) {this.weatherId = weatherId;}public int getCityId() {return cityId;}public void setCityId(int cityId) {this.cityId = cityId;}
}
