}

3.POJO类:
[java]
package com.example.touchpoint;

public class LocationPoint {

private long _id;
private double latitude;
private double longitutde;

public long get_id() {
return _id;
}

public void set_id(long _id) {
this._id = _id;
}

public double getLatitude() {
return latitude;
}

public void setLatitude(double latitude) {
this.latitude = latitude;
}

public double getLongitutde() {
return longitutde;
}

public void setLongitutde(double longitutde) {
this.longitutde = longitutde;
}

@Override
public String toString() {
return "LocationPoint [_id=" + _id + ", latitude=" + latitude
+ ", longitutde=" + longitutde + "]";
}
}
