我是android新手。我尝试在我的应用程序中创建用户，但是当我运行应用程序时，我在日志中出现此错误：
no such table: user (code 1): , while compiling: SELECT Id, Groom_Name, Groom_Family, Groom_Birthday, Groom_Address, Groom_Email, Bride_Name, Bride_Family, Bride_Birthday, Bride_Address, Bride_Email, UserName, Password, Wedding_Date, Creator, Register_time, Last_Login_Time, Mobile_Number, Mobile_Number2, State, City, Couple_Photo, Groom_Photo, Bride_Photo, License_Number, City_code, Status, Privacy, Money, bride_thumb, groom_thumb, couple_thumb, Activation FROM user
这是我的助手班：

这是我的数据源类：

public UserDatasource(Context context) {
dbhelper = new UserOpenHelper(context);
database = dbhelper.getWritableDatabase();
}
public void open() {
Log.i(LOG, "Database opened");

public void close() {

}
public User create(User user) {

long insertId = database.insert(UserOpenHelper.TABLE_NAME, null, contentValues);
user.setId(insertId);
return user;
}
public Cursor getCurrentUser() {
Cursor cursor = database.query(UserOpenHelper.TABLE_NAME, UserDatasource.ALL_COLS, null, null, null, null, null);
return cursor;
}
}
现在在MainActivity类中我想要getCurrentUser，如果不存在则调用LoginActivit：
package com.saniyeh.iwedding;
import java.util.ArrayList;
import java.util.List;
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;

import android.app.FragmentManager;
import android.content.res.Configuration;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import com.saniyeh.db.datasource.UserDatasource;
import com.saniyeh.db.openHelper.UserOpenHelper;
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
CustomDrawerAdapter adapter;
List<DrawerItem> dataList;
SQLiteDatabase sqLiteDatabase;
UserDatasource userDatasource;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
UserDatasource userDatasource = new UserDatasource(this);
userDatasource.open();
Cursor cursor = userDatasource.getCurrentUser();
}catch (Exception e){
Log.i("MGH",e.getMessage());
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
protected void onResume() {
super.onResume();
}
@Override
protected void onPause() {
super.onPause();
userDatasource.close();
}
}
答案 0 :(得分：3)
我认为您的表名是wed90_user而不是user您创建了变量TABLE_NAME，但似乎您没有在
private static final String CREATE_TABLE =
"CREATE TABLE IF NOT EXISTS wed90_user (" + ...
