I am new to SQLite. I have an activity in which I have different fields like Name,Email,Date of Birth etc. When user fill the information and clicks the save button I want it to get saved to the database. But I am stuck in mid way and don't know what to do.How to save the data from Edit Text Views to the database on Save Button click.Please help me.
I am sharing my code.

});
}

try .getText() on your EditText
like yourEditText.getText(); and set it into your NewUserDb and pass the NewUserDb object into addUser method of your DatabaseHelper class

First you declare database create table query string in your DatabaseHelper class like this:
private static final String DATABASE_CREATE_USER = "create table UserInfo("
+ "_id VARCHAR(20)," + "userGOAL VARCHAR(20),"
+ "userName VARCHAR(20)," + "userEmail VARCHAR(20),"
+ "userDOB VARCHAR(20)," + "userHeight VARCHAR(10),"
+ "userWeight VARCHAR(10)," + "userGender VARCHAR(10),"
+ "userZIP VARCHAR(10) "+ ")";
Then write inside onCreate method of DatabaseHelper
db.execSQL(DATABASE_CREATE_USER);
Then declare object of SqliteDatabase and DatabseHelper in your AcountActivity like this:
DatabaseHelper dbHelper;
SQLiteDatabase db;
Afer this write following code inside your button onClick method:
dbHelper= new DatabaseHelper(ActountActivity.this);
db = dbHelper.getWritableDatabase();
ContentValues insertValues = new ContentValues();
insertValues.put("_id", "User_Id");
insertValues.put("userGOAL", "User_Goal");
insertValues.put("userName", "User_Name");
insertValues.put("userEmail", "User_Email");
insertValues.put("userDOB", "User_DOB");
insertValues.put("userHeight", "User_Height");
insertValues.put("userWeight", "User_Weight");
insertValues.put("userGender", "User_Gender");
insertValues.put("userZIP", "User_Zip");
db.insert("UserInfo", null, insertValues);
db.close();
May this help you.

What is the proper way to load user data from database and pass it into intent extras

The project im working on allow the user to register and login and all works perfectly until I spotted something wrong with the code. It doesn't count as an error because the compiler don't think its an error. Its just a bug or whatever people call it is. So here's what happened . The user login to their account, the database transfer their data into intent extras. then on the next activities, the username, coins and gems appears on top of the page so that the user know how much coins they have left. For testing purpose, i added add coin and decrease coin button. still, the code works perfectly. But after the user log out and relogin, the coins backs to the original amount. I know the problem caused by putting a value on the coin variable in User.java class. And still while logging in I put the default value of coins and gems for the user in the intent extras. I just cant find my way on how to put the value from database to the intent extras while user logging in.
so heres the code for login activity
buttonLogin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//Check user input is correct or not
if (validate()) {
//Get values from EditText fields
String Email = editTextEmail.getText().toString();
String Password = editTextPassword.getText().toString();
User player1 = new User(null, null, Email, Password);
//Authenticate user
User currentUser = myDb.Authenticate(player1);
//Check Authentication is successful or not
if (currentUser != null) {
System.out.println("Success");
Bundle extras = new Bundle();
extras.putString("P_ID", currentUser.getId());
extras.putString("P_NAME", currentUser.getName());
extras.putInt("P_COINS", currentUser.getCoins());
extras.putInt("P_GEMS", currentUser.getGems());
Intent intent = new Intent(getApplicationContext(),HomeActivity.class);
intent.putExtras(extras);
startActivity(intent);
finish();
} else {
//User Logged in Failed
System.out.println("Failed");
}
}
}
});
the homeactivity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Set fullscreen and no title//////////
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
///////////////////////////////////////
setContentView(R.layout.home_screen);
myDb = new DatabaseHelper(this);
Intent intent = getIntent();
Bundle extras = intent.getExtras();
pid = extras.getString("P_ID");
pname = extras.getString("P_NAME");
pcoins = extras.getInt("P_COINS");
pgems = extras.getInt("P_GEMS");
nametxt = (TextView)findViewById(R.id.playernametext);
coinstxt = (TextView)findViewById(R.id.playercoinstext);
gemstxt = (TextView)findViewById(R.id.playergemstext);
addcoin = (Button)findViewById(R.id.addbtn);
decoin = (Button)findViewById(R.id.decbtn);
nametxt.setText(" " +String.valueOf(pname) +" ");
coinstxt.setText(" Coins : " +String.valueOf(pcoins) +" ");
gemstxt.setText(" Gems : " +String.valueOf(pgems) +" ");
addcoin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pcoins += 10;
boolean isUpdate = myDb.updateUser(pid, pname, String.valueOf(pcoins), String.valueOf(pgems));
if (isUpdate == true) {
nametxt.setText(" " +String.valueOf(pname) +" ");
coinstxt.setText(" Coins : " +String.valueOf(pcoins) +" ");
gemstxt.setText(" Gems : " +String.valueOf(pgems) +" ");
}
}
});
decoin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pcoins -= 10;
boolean isUpdate = myDb.updateUser(pid, pname, String.valueOf(pcoins), String.valueOf(pgems));
if (isUpdate == true) {
nametxt.setText(" " +String.valueOf(pname) +" ");
coinstxt.setText(" Coins : " +String.valueOf(pcoins) +" ");
gemstxt.setText(" Gems : " +String.valueOf(pgems) +" ");
}
}
});
}
and of course the user class
public class User {
public String id;
public String userName;
public String email;
public String password;
public int coins = 1000;
public int gems = 10;
public User(String id, String userName, String email, String password) {
this.id = id;
this.userName = userName;
this.email = email;
this.password = password;
}
public String getId() {
return this.id;
}
public String getName() {
return this.userName;
}
public void addCoins(int addAmount) {
this.coins = addAmount;
}
public void decCoins(int decAmount) {
this.coins = decAmount;
}
public int getCoins() {
return this.coins;
}
public void addGems(int addAmount) {
this.gems = addAmount;
}
public void decGems(int decAmount) {
this.gems = decAmount;
}
public int getGems() {
return this.gems;
}
}
Honestly, my brain lacks of logic. Thats why i come here, to see whether my code does make sense.
And please, if you don't understand what i mean, just ask me which parts and please just dont immediately flag my question. Im really bad at english, trust me.

I'd suggest only passing the userid (which should never change) and then always getting the values coins etc from the database and also only changing them in the database (followed by resetting the displayed values from the values in the database).
You would then not have the issue of trying to juggle two sets of data you would then rely on the real data i.e. that in the database.
Working Example
The following is some code that goes through the basics.
When it starts the MainActivity, immediately starts the LoginActivity when you login then it takes you to the HomeActivity. This display the current Userid, Username, coins (initially 0) and gems.
There are 2 buttons Add10Coins and Add10gems clicking them will apply the new values to the DB displaying the updated values. If you stop the App and rerun, login then the values will be as they were.
Passing values wise, although the LoginActivity sets 3 Intent Extra values only one is used (the userid as a long) by the HomeActivity, but as per the values display all are accessible. If another activity is started then all you have to do is pass the userid via the intent.
The code isn't what I'd call complex but I'd certainly suggest going through it and try to understand it.
user.java
I've added some methods and also added some Constants, this is now :-
public class User {
public static final int ADJUSTTYPE_ADD = 1;
public static final int ADJUSTTYPE_REPLACE = 2;
public static final int ADJUSTTYPE_MULTIPLY = 3;
public static final int ADJUSTTYPE_DIVIDE = 4;
String id;
String userName;
String email;
String password;
int coins;
int gems;
public User(String id, String userName, String email, String password) {
this.id = id;
this.email = email;
//And so on. Don't mind this
}
public void setId(String id) {
this.id = id;
}
public String getId() {
return id;
}
public void setName(String userName) {
this.userName = userName;
}
public String getName() {
return this.userName;
}
public void setEmail(String email) {
this.email = email;
}
public String getEmail() {
return email;
}
public void setPassword(String password) {
this.password = password;
}
public String getPassword() {
return password;
}
public void setCoins(int coins) {
this.coins = coins;
}
public int getCoins() {
return this.coins;
}
public void setGems(int gems) {
this.gems = gems;
}
public int getGems() {
return this.gems;
}
public long getLongId() {
long id;
try {
id = Long.valueOf(this.id);

return id;
}
}
DatabaseHelper.java
This has been written from scratch based upon not the most stringent inspection of your code, it will largely be affected by my styling/usage techniques but not to the extent that I'd apply for real development.
Within this is the method adjustCoinsAndOrGems this is what is used to update the gems or coins in the DB and also in the returned User (so that a synchronised version of the User is returned, not that this returned use is used (I personally prefer to access the database as long as it's not an issue (e.g. noticeably affects performance)))

MainActivity.java
Very simple activity that starts the LoginActivity and when finally returned to does nothing (so you might as well kill the app).
public class MainActivity extends AppCompatActivity {
TextView mMessage;
DatabaseHelper mDB;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMessage = this.findViewById(R.id.message);
mDB = new DatabaseHelper(this);
addSomeTestingUsers();
// Immediately start Login Activity
Intent i = new Intent(MainActivity.this,LoginActivity.class);
startActivity(i);
}
#Override
protected void onResume() {
super.onResume();
mMessage.setText("Welcome back");
}
private void addSomeTestingUsers() {
if (DatabaseUtils.queryNumEntries(mDB.getWritableDatabase(),DatabaseHelper.TBL_USER) > 0) return;
mDB.addUser("Fred","fred#fredmal.com","password");
mDB.addUser("Mary","mary#mary.email.com","password");
}
}
LoginActivity
This is pretty straightforward note that as it stands you have to Login and that the emails and passwords for the 2 users are coded in the MainActivity. When supplied correctly the HomeActivivty is started :-
public class LoginActivity extends AppCompatActivity {
public static final String INTENTKEY_USERNAME = "IK_USERNAME";
public static final String INTENTKEY_USERID = "IK_USERID";
public static final String INTENTKEY_STRINGUSERID = "IK_USERIDSTRING";
Button mloginbtn;
EditText mEmail,mPassword;
Context mContext;
DatabaseHelper mDB;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
mContext = this;
mloginbtn = this.findViewById(R.id.loginbtn);
mEmail = this.findViewById(R.id.email);
mPassword = this.findViewById(R.id.password);
mDB = new DatabaseHelper(this);
mloginbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
handleAuthentication();
}
});
}
private void handleAuthentication() {
if (mDB.authenticateUser(mEmail.getText().toString(),mPassword.getText().toString())) {
User u = mDB.getUser(mEmail.getText().toString(),mPassword.getText().toString());
Intent i = new Intent(mContext,HomeActivity.class);

table has no column named -Sqlite -android-my first app

Yes I have read many many answers here on SO and tried all but nothing works for me. I dont know what is wrong because according to me everything looks good.
Many times I changed DB version,. Even I renamed db and table name but nothing works. I can print the log which shows the correct result but why it is not inserting into the database.
Also When I remove all the Checkbox fields from table then data insertion works.
A humble request..please do not block me from asking question as this question is asked many times by others and I tried all solutions but nothing worked.
Please guide me as I am completely new to Java and Android Studio.

You are missing comma(,) after "TEXT" in your CREATE_CONTACTS_TABLE query
KEY_ZIP + " TEXT " + KEY_SALOON + " TEXT " + KEY_COSMO + " TEXT " + KEY_STUDENT
+ " TEXT " + KEY_OTHER + " TEXT " + KEY_ADD_INFO + " TEXT "
Try after doing this change. It should work, and if you still get this error, check your table structure using Android Device Monitor if you are using emulator and debug your code.

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?

One Problem I see is in your insertPerson() method. Don't include the "" in the values.put()
try replacing below code
ContentValues values = new ContentValues();
values.put("PERSON_USERNAME", person.getUsername());
values.put("PERSON_HEIGHT", person.getHeight());
values.put("PERSON_WEIGHT", person.getWeight());
values.put("PERSON_AGE", person.getAge());
values.put("PERSON_GENDER", person.getGender());
values.put("PERSON_PA", person.getPa());
values.put("PERSON_BMI", person.getBmivalue());
values.put("PERSON_INTERPRETAION", person.getBmiInterpretation());
values.put("PERSON_IDEALWEIGHT", person.getIdealweight());
values.put("PERSON_DAILYCALORIES", person.getDailycalories());
with
ContentValues values = new ContentValues();
values.put(PERSON_USERNAME, person.getUsername());
values.put(PERSON_HEIGHT, person.getHeight());
values.put(PERSON_WEIGHT, person.getWeight());
values.put(PERSON_AGE, person.getAge());
values.put(PERSON_GENDER, person.getGender());
values.put(PERSON_PA, person.getPa());
values.put(PERSON_BMI, person.getBmivalue());
values.put(PERSON_INTERPRETATION, person.getBmiInterpretation());
values.put(PERSON_IDEALWEIGHT, person.getIdealweight());
values.put(PERSON_DAILYCALORIES, person.getDailycalories());

First you'll need to create a layout file that will represent how you want to display each list item.
Then you'll need to extend the BaseAdapter class so that you can decide how you want to display each Kovil class.
Once that is constructed, you can call setAdapter on your ListView.
