I checked this one and couldn't find the solution for solve it. This is user profile class to handle user profiles.
UserProfile.java
package com.modelpaper.mad.it17121002;
public final class UserProfile {
private UserProfile(){
}
public static UserProfile getProfile(){
UserProfile userProfile = new UserProfile();
return userProfile;
}

public static final String TABLE_NAME = "UserInfo";
public static final String COL_ID = "_ID";
public static final String COL_USERNAME = "userName ";
public static final String COL_DOB = "dateOfBirth";
public static final String COL_GENDER = "Gender";
public static final String COL_PASSWORD = "Password";
//displya karana ona variable tika
private int id;
private String username;

Is there like any way to edit my listview once a longclick listener event has happened? I have tried doing the same thing with delete it's because I don't have really any idea how to edit a listview after a longclick.

how to create login activity using existing database that have informations

I've existing database that have name, surname, email phone and password and I want to use that to make login activity that have two edit text (Email or phone number) & (password).

Add this function to your DatabaseHelper.java
public boolean userExistance(String emailOrPhone, String pwd){
String sql = "select * from " + TABLE_NAME + " where ("+ COL_3 +" = " + emailOrPhone +" OR "+ COL_4 +" = "+ emailOrPhone+ ") AND " + COL_5 + " = " + pwd;
SQLiteDatabase mydb = this.getWritableDatabase();
Cursor cursor = mydb.rawQuery(sql, null);
if(cursor.getCount() > 0)
return true;
else
return false;
}
Then add call this function from your LoginActivity.java
DatabaseHelper mydb;
mydb = new DatabaseHelper(LoginActivity.this);
boolean exists = mydb.userExistance();
if(exists)
{
Intent intent = new Intent(Login.this, Parent_Home.class);
Toast.makeText(this, "Success", Toast.LENGTH_SHORT).show();
startActivity(intent);
finish();
}
Add below method in your DatabaseHelper class.
public ArrayList<ParentModel> getParentData(String emailOrPhone,String pwd){
ArrayList<ParentModel> list = new ArrayList<>();
String sql = "SELECT * FROM " + TABLE_NAME+" WHERE ("+COL_3+"= "+emailOrPhone+" OR "+COL_4 +" = "+emailOrPhone+") AND "+COL_5 +" = "+pwd;
SQLiteDatabase mydb = this.getWritableDatabase();
Cursor cursor = mydb.rawQuery(sql, null);
if (cursor.moveToFirst()) {
do {
ParentModel parentModel = new ParentModel();
parentModel.setID(cursor.getString(0));
parentModel.setName(cursor.getString(1));
parentModel.setSurname(cursor.getString(2));
parentModel.setEmail(cursor.getString(3));
parentModel.setPhone_number(cursor.getString(4));
parentModel.setPassword(cursor.getString(5));
list.add(parentModel);
}
while (cursor.moveToNext());
}
return list;
}
And use like below code :
if (mydb.getParentData(editTextEmailPhone.getText().toString(),editTextPassword.getText().toString()).size()>0)
{
progressDialog.dismiss();
SharedPrefs.saveSharedSetting(this, "CaptainCode", "false");
Intent intent = new Intent(Login.this, Parent_Home.class);
Toast.makeText(this, "Success", Toast.LENGTH_SHORT).show();
startActivity(intent);
finish();
}
Don't forget to initialization DatabaseHelper mydb.

You can pass the values to the activity using Intent Extras when starting an activity via an Intent.
So you use something like :-
ArrayList<ParentModel> parents = mydb.getParentLoginData(editTextEmailPhone.getText().toString(),editTextPassword.getText().toString());
if (parents.size()>0) {
progressDialog.dismiss();
DatabaseHelper mydb = new DatabaseHelper(this);
SharedPrefs.saveSharedSetting(this, "CaptainCode", "false");
Intent intent = new Intent(Login.this, Parent_Home.class);
intent.putExtra("IK_CURRENTPARENTID",parents[0].getId());
intent.putExtra("IK_CURRENTPARENTNAME",parents[0].getName());
intent.putExtra("IK_CURRENTPARENTSURNAME",parents[0].getSurname();
// intent or something to forward the data from the selected parent row from the database
Toast.makeText(this, "Success", Toast.LENGTH_SHORT).show();
startActivity(intent);
finish();
}
You then retrieve the values from the Intent Extras in the Parent_Home activity. using something like in the onCreate method :-
currentId = getIntent().getStringExtra("IK_CURRENTPARENTID");
currentName = getIntent().getStringExtra("IK_CURRENTPARENTNAME");
currentSurName = getIntent().getStringExtra("IK_CURRENTPARENTSURNAME");
noting that the above assumes that currentId, currentName and currentSurName have been declared as class variables.
typically you'd also define constants for the Intent Extra keys rater than hard coding them.
The above is in-principle code, it hasn't been run or tested and may therefore contain some errors.

signup button linked to sqlite database

public void onSignUpClick(View v){

String namestr = name.getText().toString();
String emailstr = name.getText().toString();
String pass1str = name.getText().toString();
String pass2str = name.getText().toString();
if(!pass1str.equals(pass2str))
{
//popup msg:
Toast tpass = Toast.makeText(signup.this, "passwords don't match", Toast.LENGTH_LONG);
tpass.show();
}
else
{
//insert the details in DB:
Contact c = new Contact();
c.setName(namestr);
c.setEmail(emailstr);
c.setPass(pass1str);
helper.insertContact(c);
}
}
}
I'm trying to make a signup form linked to sqlite database. the registraion button that's linked to onSignUpClick method doesn't work. any help to fix this error?
I have implemented a similar functionality to my app.. You can use this as a reference.You need to add whatever elements needed for your signup activity.
1. Create a database handler for your sqlite application.(DatabaseHandler.java)
import java.util.ArrayList;
import java.util.List;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
public class DatabaseHandler extends SQLiteOpenHelper {
public DatabaseHandler(Context context, Object name,
Object factory, int version) {
// TODO Auto-generated constructor stub
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
String password;
// Database Version
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = "Mydatabase.db";
// Contacts table name
private static final String TABLE_REGISTER= "register";
public static final String KEY_EMAIL_ID="email_id";
public static final String KEY_MOB_NO = "mobile_number";
public static final String KEY_PASSWORD = "password";
public static final String CREATE_TABLE="CREATE TABLE " + TABLE_REGISTER + "("
+ KEY_EMAIL_ID+ " TEXT,"
+ KEY_MOB_NO + " TEXT," + KEY_PASSWORD + " TEXT " + ")";
#Override
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
db.execSQL(CREATE_TABLE);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// TODO Auto-generated method stub
// Drop older table if existed
db.execSQL("DROP TABLE IF EXISTS " + TABLE_REGISTER);
// Create tables again
onCreate(db);
}
void addregister(UserRegister registerdata)
// code to add the new register
{
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(KEY_EMAIL_ID, registerdata.getEmailId());//register email id
values.put(KEY_MOB_NO, registerdata.getMobNo());//register mobile no
values.put(KEY_PASSWORD, registerdata.getPassword());
// Inserting Row
db.insert(TABLE_REGISTER, null, values);
db.close(); // Closing database connection
}
//code to get the register
String getregister(String username){
SQLiteDatabase db = this.getReadableDatabase();
//String selectquery="SELECT * FROM TABLE_REGISTER";
Cursor cursor=db.query(TABLE_REGISTER,null, "email_id=?",new String[]{username},null, null, null, null);
if(cursor.getCount()<1){
cursor.close();
return "Not Exist";
}
else if(cursor.getCount()>=1 && cursor.moveToFirst()){
password = cursor.getString(cursor.getColumnIndex(KEY_PASSWORD));
cursor.close();
}
return password;
}
public String getDatabaseName() {
return DATABASE_NAME;
}
public static String getTableContacts() {
return TABLE_REGISTER;
}
public static int getDatabaseVersion() {
return DATABASE_VERSION;
}
}
2. Create a modal class UserRegister
public class UserRegister {
//private variables
String email_id;
String mobile_number;
String password;
// Empty constructor
public UserRegister(){}
// constructor
public UserRegister( String email_id,String mobile_number, String password){
this.email_id=email_id;
this.mobile_number=mobile_number;
this.password = password;
}
public String getEmailId() {
return email_id;
}
public void setEmailId(String email_id){
this.email_id = email_id;
}
public String getMobNo() {
// TODO Auto-generated method stub
return mobile_number;
}
public void setMobNo(String mobile_number){
this.mobile_number=mobile_number;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
3.Create the RegistrationActivity
public class Registration_Activity extends AppCompatActivity {
EditText reg_email,reg_phone,reg_password;
Button reg_button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.register);
final DatabaseHandler db = new DatabaseHandler(this, null, null, 2);
reg_email = (EditText)findViewById(R.id.reg_email);
reg_phone = (EditText)findViewById(R.id.reg_phone);

pass Data from a List View (generated from Rest Api) to another activity and save that into SQLite Database

I am creating an android app (still the basic structure, without any design) from an Job site through XML feed using REST api.
Till now, I could managed to parse the XML data, displaying the List View with an POP UP menu item on each row. I am passing Data from PostBaseAdapter to MarkAsFav class. Could You please tell me if I am doing right or not? coz, I am getting no any data saved in database
Now, I have a problems:
I have 3 pop up menu item:
1. Set as Favourite
2. Share on Fb
3. email to Your friend
I am working on point number-1.
For now,I would be saving the data in SQLite Database itself. so, I am passing all the data (all the details about the job with all rows) to another activity, more over I am accepting a user given name to save the details through insertDB() in my Database.
But, unfortunately , nothing is getting saved in the database .
Can you tell me, if the data is getting passed or not and if the datas are being saved in database or not?
Please help me out. Please tell me where and how to modify the code?
