I am trying to create login page with sqlite with multiple columns but unable to insert values in it :
Here is my insertion query code:
package com.example.doctorsmanager;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
public class DataBaseAdapter
{
static final String DATABASE_NAME = "doctordb";
static final int DATABASE_VERSION = 2;
static final String USERNAME_COLUMN = "UserName";
static final String PASSWORD_COLUMN = "Password";
static final String QUALIFICATION_COLUMN = "Qualification";
static final String SPECIALIZATION_COLUMN = "Specialization";
static final String COLUMN_ID = "id";
static final String REGISTRATIONNUMBER_COLUMN = "RegistrationNumber";
static final String CELLNUMBER_COLUMN = "CellNumber";
static final String DATABASE_CREATE = "create table "+"LOGIN"+
"( " +"ID"+" integer primary key autoincrement,"+ "USERNAME text,PASSWORD String,QUALIFICATION String,SPECIALIZATION text,REGISTRATIONNUMBER String,CELLNUMBER integer,MAIL String); ";
public SQLiteDatabase db;
private final Context context;
private DataBaseHelper dbHelper;
public DataBaseAdapter(Context _context)
{
context = _context;
dbHelper = new DataBaseHelper(context, DATABASE_NAME, null, DATABASE_VERSION);
}
public DataBaseAdapter open() throws SQLException
{
db = dbHelper.getWritableDatabase();
return this;
}
public void close()
{
db.close();
}
public SQLiteDatabase getDatabaseInstance()
{
return db;
}
public void insertEntry(String userName,String password,String qualification,String specialization,String registrationNumber,String cellNumber,String mailId )
{
ContentValues newValues = new ContentValues();
newValues.put("USERNAME", userName);
newValues.put("PASSWORD",password);
newValues.put("QUALIFICATION",qualification);
newValues.put("SPECIALIZATION",specialization);
newValues.put("REGISTRATIONNUMBER",registrationNumber);
newValues.put("CONTACTNUMBER",cellNumber);
newValues.put("EMAIL",mailId);
db.insert("LOGIN", null, newValues);
System.out.println("USERNAME");
System.out.println("PASSWORD");
}
public int deleteEntry(String UserName)
{
String where="USERNAME=?";
int numberOFEntriesDeleted= db.delete("LOGIN", where, new String[]{UserName}) ;
return numberOFEntriesDeleted;
}
public String getSinlgeEntry(String userName)
{
Cursor cursor=db.query("LOGIN", null, " USERNAME=?", new String[]{userName}, null, null, null);
if(cursor.getCount()<1)
{
cursor.close();
return "NOT EXIST";
}
cursor.moveToFirst();
String password= cursor.getString(cursor.getColumnIndex("PASSWORD"));
cursor.close();
return password;
}
public void updateEntry(String userName,String password,String qualification,String specialization,String registrationNumber,String cellNumber,String mailId)
{
ContentValues updatedValues = new ContentValues();
updatedValues.put("USERNAME", userName);
updatedValues.put("PASSWORD",password);
updatedValues.put("QUALIFICATION",qualification);
updatedValues.put("SPECIALIZATION",specialization);
updatedValues.put("REGISTRATIONNUMBER",registrationNumber);
updatedValues.put("CONTACTNUMBER",cellNumber);
updatedValues.put("EMAIL",mailId);
String where="USERNAME = ?";
db.update("LOGIN",updatedValues, where, new String[]{userName});
}
}
And here is the code on the signup page when user press the `button` to create account:
btnCreateAccount.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String userName=editTextUserName.getText().toString();
String password=editTextPassword.getText().toString();
String qualification=editTextQualification.getText().toString();
String specializaion=editTextSpecialization.getText().toString();
String registrationNumber=editTextRegistrationNumber.getText().toString();
String cellNumber=editTextCellNumber.getText().toString();
String mailId=editTextMail.getText().toString();
if(userName.equals("")||password.equals(""))
{
Toast.makeText(getApplicationContext(), "Field Vaccant", Toast.LENGTH_LONG).show();
return;
}
if(!password.equals(password))
{
Toast.makeText(getApplicationContext(), "Password does not match", Toast.LENGTH_LONG).show();
return;
}
else
{
DataBaseAdapter.insertEntry(userName,password,qualification,specializaion,registrationNumber,cellNumber,mailId);
Toast.makeText(getApplicationContext(), "Account Successfully Created ", Toast.LENGTH_LONG).show();
and here is the query for main login page for successful login:
btnLogIn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String userName=editTextUserName.getText().toString();
String password=editTextPassword.getText().toString();
String storedPassword=DataBaseAdapter.getSinlgeEntry(userName);
if(password.equals(storedPassword))
{
Toast.makeText(MainActivity.this, "Congrats: Login Successfull", Toast.LENGTH_LONG).show();
}`enter code here`
else
{
Toast.makeText(MainActivity.this, "User Name or Password does not match", Toast.LENGTH_LONG).show();
}
}
});
This is my database helper class:
package com.example.doctorsmanager;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteDatabase.CursorFactory;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;
public class DataBaseHelper extends SQLiteOpenHelper
{
public DataBaseHelper(Context context, String name,CursorFactory factory, int version)
{
super(context, name, factory, version);
}
@Override
public void onCreate(SQLiteDatabase _db)
{
_db.execSQL(DataBaseAdapter.DATABASE_CREATE);
}
@Override
public void onUpgrade(SQLiteDatabase _db, int _oldVersion, int _newVersion)
{
Log.w("TaskDBAdapter", "Upgrading from version " +_oldVersion + " to " +_newVersion + ", which will destroy all old data");
_db.execSQL("DROP TABLE IF EXISTS " + "TEMPLATE");
onCreate(_db);
}
}
This is log cat:
