安卓sqlite的问题，不能点注册按钮，点了就出错。然后控制台那边提示说是such no table，网上也查找过解决办法，说是把路径定死，可惜不知道哪里写合适，或者试了也不行？

}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.login, menu);

}
}
还有就是声明user对象的属性
public class User {
private String name;
private String password;
private String yhsfz;
private String yhxm;
private String yhyx;
private String yhdh;
private String sex;
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
public String getPassword(){
return name;
}
public void setPassword(String password){
this.password = password;
}
public String getYhsfz(){
return yhsfz;
}
public void setYhsfz(String yhsfz){
this.yhsfz = yhsfz;
}
public String getYhxm(){
return yhxm;
}
public void setYhxm(String yhxm){
this.yhxm = yhxm;
}
public String getYhyx(){
return yhyx;
}
public void setYhyx(String yhyx){
this.yhyx = yhyx;
}
public String getYhdh(){
return yhdh;
}
public void setYhdh(String yhdh){
this.yhdh = yhdh;
}
public String getSex(){
return sex;
}
public void setSex(String sex){
this.sex = sex;
}
不知道该如何解决，可能是哪里的代码写错了，望各路大神能指点下，感谢！
