SQLite db isn't created - java

I have problem with sqlite database adapter in my project.I'm new to android development so I don't have much idea to how can handle this problem. I want to save user information in data base .Although no error while execution,database doesn't create? can any one help.

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());

Getter returning null when testing get methods

I am trying to get data from my database to show on a listview. The problem I am having is it seems the getters are not working properly. When I test what they are returning, it comes back null.
Any insight would be appreciated as I am lost here. Thanks in advance.
Here is where I initialise the class:
public ArrayList<GameStats> getAllData() {
ArrayList<GameStats> arrayList = new ArrayList<>();
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery("SELECT * FROM savedGamesTable", null);
while(cursor.moveToNext()){
int id = cursor.getInt(0);
String lName = cursor.getString(1);
int lScore = cursor.getInt(2);
String rName = cursor.getString(3);
int rScore = cursor.getInt(4);
String notes = cursor.getString(5);
GameStats gameStats = new GameStats(id, lName, lScore, rName, rScore, notes);
arrayList.add(gameStats);
}
return arrayList;
}
Here is where I am trying to use the getters:
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.activity_saved_games, null);
TextView lName = convertView.findViewById(R.id.lName);
TextView lScore = convertView.findViewById(R.id.lScore);
TextView rName = convertView.findViewById(R.id.rName);
TextView rScore = convertView.findViewById(R.id.rScore);
TextView notes = convertView.findViewById(R.id.notes);
GameStats gameStats = arrayList.get(position);
testVar = gameStats.getlName();
Log.d("MyAdaptor","gameStats = " + var);
lName.setText(gameStats.getlName());
lScore.setText(String.valueOf(gameStats.getlScore()));
rName.setText(gameStats.getrName());
rScore.setText(String.valueOf(gameStats.getrScore()));
notes.setText(gameStats.getNotes());
return convertView;
}
Here is the model class:
public class GameStats {
int id, lScore, rScore;
String lName, rName, notes;
public GameStats(int id, String lName, int lScore, String rName, int rScore, String notes) {
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getlScore() {
return lScore;
}
public void setlScore(int lScore) {
this.lScore = lScore;
}
public int getrScore() {
return rScore;
}
public void setrScore(int rScore) {
this.rScore = rScore;
}
public String getlName() {
return lName;
}
public void setlName(String lName) {
this.lName = lName;
}
public String getrName() {
return rName;
}
public void setrName(String rName) {
this.rName = rName;
}
public String getNotes() {
return notes;
}
public void setNotes(String notes) {
this.notes = notes;
}
}
and here is where I am calling the methods:
public class SavedGameScreen extends AppCompatActivity {
ListView lv1;
ArrayList<GameStats> arrayList;
MyAdaptor myAdaptor;
DatabaseHelper databaseHelper;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_saved_game_screen);
lv1 = findViewById(R.id.lv1);
databaseHelper = new DatabaseHelper(this);
arrayList = new ArrayList<>();
loadData();
}
private void loadData() {
arrayList = databaseHelper.getAllData();
myAdaptor = new MyAdaptor(this, arrayList);
lv1.setAdapter(myAdaptor);
myAdaptor.notifyDataSetChanged();
}
}

Please change the constructor as below and see if that works,
public GameStats(int id, String lName, int lScore, String rName, int rScore, String notes) {
this.id = id;
this.lName = IName;
this.lScore = IScore;
this.rName = rName;
this.rScore = rScore;
this.notes = notes;
}

In your model class initialize the variables using constrtuctor. I guess that is the problem. Since you are not initializing the model class properties, it the getters will return "null" or any garbage value

You are passing the values to the model constructor but you are not assigning it to the model variables. You need to change the code as below,
public GameStats(int id, String lName, int lScore, String rName, int rScore, String notes) {
this.id = id;
this.lName = IName;
this.lScore = IScore;
this.rName = rName;
this.rScore = rScore;
this.notes = notes;
}
Else initialise each variable through setter() method.

How to put Array value to Database on dbSqlite?

My project used to save products information into shoppingCart on a database with dbSqlite. But, for now it should save information of product from server. According to web service, one variable type is List Array. It was String before. And one of them is double, it was String also. I changed real in dbSqlite but what I should do for Array? How can save it on dbSqlite again?
error: no suitable method found for put(String,List) method
ContentValues.put(String,String) is not applicable

SQLiteDatabase db = this.getWritableDatabase();
Cursor rs = db.rawQuery( "select * from cart",null);
StringBuffer stringBuffer = new StringBuffer();
Cart dataModel = null;
while (rs.moveToNext()) {
dataModel= new Cart();
List<String> image = Collections.singletonList(rs.getString(rs.getColumnIndexOrThrow("Image")));
String title = rs.getString(rs.getColumnIndexOrThrow("Title"));
Double cost = (rs.getDouble(rs.getColumnIndexOrThrow("Cost")));
String market = rs.getString(rs.getColumnIndexOrThrow("Market"));
String totalCost = rs.getString(rs.getColumnIndexOrThrow("TotalCost"));
String description = rs.getString(rs.getColumnIndexOrThrow("Description"));

dataModel.setMarket(market);
dataModel.setTotalCost(totalCost);
dataModel.setDescription(description);
stringBuffer.append(dataModel);
data.add(dataModel);
}
return data;
}
}

You can read the array like this :
String[] myArray = `put your array here`
for (int i = 0; i < myArray.size(); i++)
{
//Here u insert the data by getting what u need from the array
data.put("Cost",myArray.get(i).Cost);
}

You should be fine serializing the list to string. I. e. you could serialize it to json and deserialize it if you need it again.
Here is a small code example for two functions you could use in your DatabaseHelper.
private String serialize(List<String) list) {
JSONArray jsonArray = new JSONArray();
for (String s : list) {
jsonArray.put(s);
}
return jsonArray.toString();
}
private List<String> deserialize(String json) {
JSONArray jsonArray = new JSONArray(json);
List<String> list = new ArrayList<>();
for (int i=0; i<jsonArray.getLength(); ++i) {
list.add(jsonArray.getString(i));
}
return list;
}
And then you can use these functions:
data.put("Image",serialize(Image));
List<String> image = deserialize(rs.getString(rs.getColumnIndexOrThrow("Image")));
(This is only pseudo-code. Maybe you need to adjust it. Furthermore the functions don't handle null-parameters and may throw NullPointerExceptions!)

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?

You're not actually adding the database records to the results collection in listfromdb().
Should be something like:
public ArrayList<Listcollection> listfromdb() {
SQLiteDatabase db = this.getReadableDatabase();
ArrayList<Listcollection> results = new ArrayList<Listcollection>();
Cursor crs = db.rawQuery("select * from contacts", null);
while (crs.moveToNext()) {
Listcollection item = new Listcollection();
item.setId(crs.getInt(crs.getColumnIndex(CONTACTS_COLUMN_ID)));
item.setName(crs.getString(crs.getColumnIndex(C_NAME)));
item.setDate(crs.getString(crs.getColumnIndex(C_DATE)));
list.setPhone(crs.getString(crs.getColumnIndex(C_PHONE)));
results.add(item);
}
db.close();
return results;
}

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.
