SQLite ile oluşturduğum database'e insert işlemi yaparken has no column name problemi alıyorum kodlar ;

Veritabani.class:

package com.gokhangoy.diary; import android.content.ContentValues;

import android.content.Context;

import android.database.sqlite.SQLiteDatabase;

import android.database.sqlite.SQLiteOpenHelper;

 public class Veritabani extends SQLiteOpenHelper {

final public static String Database_Name = "GunlukUygulamasi";

final public static String Table_Name_Kullanicilar = "Kullanicilar";

final public static String Table_Name_Login = "Login"; f

inal public static String GunCol_0="ID";

final public static String GunCol_1="Adi";

final public static String GunCol_2="SoyAdi";

final public static String GunCol_3="Email";

final public static String GunCol_4="Password";

final public static String LogCol_1="KullaniciAdi";

final public static String LogCol_2="Password";

public Veritabani(Context context) { super(context, Database_Name, null,11); // SQLiteDatabase db =this.getWritableDatabase(); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL("CREATE TABLE "+Table_Name_Kullanicilar+ "(ID INTEGER PRIMARY KEY AUTOINCREMENT,ADI TEXT,SOYADI TEXT,EMAIL TEXT,PASSWORD TEXT)");

db.execSQL("CREATE TABLE " + Table_Name_Login + "(KULLANICIADI TEXT,PASSWORD TEXT)"); // onUpgrade(db,1,4); }

@Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

db.execSQL("DROP TABLE IF EXISTS " + Table_Name_Kullanicilar); db.execSQL("DROP TABLE IF EXISTS "+Table_Name_Login); onCreate(db);  ; }

public boolean KullaniciEkle(String Adi,String Soyadi,String Email,String Password) {

SQLiteDatabase db = this.getWritableDatabase(); //This line for checking ContentValues

con = new ContentValues();

con.put("GunCol_1",Adi);

con.put("GunCol_2",Soyadi);

con.put("GunCol_3",Email);

con.put("GunCol_4", Password);

long result = db.insert(Table_Name_Kullanicilar,null,con);

if(result == -1) return false;

else return true; } }
 

MainActivity.class:

package com.gokhangoy.diary;

import android.database.sqlite.SQLiteOpenHelper;

import android.support.v7.app.ActionBarActivity;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.view.View;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;

public class MainActivity extends ActionBarActivity {

Button btnLogIn;

EditText Adi,Soyadi,Email,Password ;

Veritabani mydb;

@Override protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

mydb = new Veritabani(this);

Adi = (EditText) findViewById(R.id.editText);

Soyadi = (EditText) findViewById(R.id.editText2);

Email = (EditText) findViewById(R.id.editText3);

Password = (EditText) findViewById(R.id.editText4);

btnLogIn = (Button) findViewById(R.id.button);

VeriEkle(); }

public void VeriEkle() {

btnLogIn.setOnClickListener(new View.OnClickListener() {

@Override public void onClick(View v) {

boolean kontrol = mydb.KullaniciEkle(Adi.getText().toString(),Soyadi.getText().toString(), Email.getText().toString(),Password.getText().toString());

if(kontrol == true)

Toast.makeText(getApplicationContext(), "Eklendi", Toast.LENGTH_LONG).show();

else Toast.makeText(getApplicationContext(),"Eklenemedi",Toast.LENGTH_LONG).show(); } }); } }
