Can't save chosen item from spinner to database

I have problem with my database. I want to save selected item from spinner to sql database. The problem is,i don't know why, but i can't save chosen item from spinner to database. I was trying out this database with EditText and everything was fine.
MainActivity :
public class MainActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
DatabaseHelper db;
Spinner spinner;
Button addData, showData;
TextView saveChosenItemFromSpinner;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
db = new DatabaseHelper(this);
addData = (Button) findViewById(R.id.addDataBtn);
showData = (Button) findViewById(R.id.showDataBtn);
spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.spinnerDemo, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(this);
saveChosenItemFromSpinner = (TextView) findViewById(R.id.text);
AddData();
// showData();
}
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
String text = adapterView.getItemAtPosition(i).toString();
saveChosenItemFromSpinner.setText(text);
// Toast.makeText(adapterView.getContext(), text, Toast.LENGTH_SHORT).show();
AddData();
}
public void AddData() {
addData.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean isInserted = db.insertData(saveChosenItemFromSpinner.getText().toString() );
if (isInserted)
Toast.makeText(MainActivity.this, "Data Inserted", Toast.LENGTH_LONG).show();
else
Toast.makeText(MainActivity.this, "Data not Inserted", Toast.LENGTH_LONG).show();
}
}
);
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
}
DatabaseHelper class :
public static final String DATABASE_NAME = "TrainingPlan.db";
public static final String TABLE_NAME = "Chest";
public static final String COL_1 = "ID";
public static final String COL_2 = "Upper_section";
public DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, 1);
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("create table " + TABLE_NAME + " (ID INTEGER PRIMARY KEY AUTOINCREMENT,UpperSectionExercises TEXT)");
}
#Override
public void onUpgrade(SQLiteDatabase db, int i, int i1) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
onCreate(db);
}
public boolean insertData(String upperSectionExercisesString) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(COL_2, upperSectionExercisesString);
long result = db.insert(TABLE_NAME, null, contentValues);
if (result == -1) {
return false;
} else
return true;
}
}
I've tried to find solution on my own,but i find nothing. Can i have some tips?

You are using different key with content values than your column name.
use
contentValues.put("UpperSectionExercises", upperSectionExercisesString);
or change your create statement.

Your Table creation query is wrong. It will be like
db.execSQL("create table " + TABLE_NAME + " (ID INTEGER PRIMARY
KEY AUTOINCREMENT, "+ COL_2+" TEXT)");

By long clicking on listview delete its contents from SQLite and listview that is clicked

Can anyone show me how to delete contents from an SQLite database and listview by long clicking on it? Also, do I have to delete only contents from SQLite database or from both SQLite database and listview?
Here are my project classes:
Database Helper
public class DatabaseHelper extends SQLiteOpenHelper {
private static final int DATABASE_VERSION = 3;
private static final String DATABASE_NAME = "products.db";
private static final String TABLE_NAME = "products";
private static final String COLUMN_ID = "_id";
private static final String MARKET = "market";
private static final String PRODUCT = "product";
private SQLiteDatabase db;
public DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("CREATE TABLE " + TABLE_NAME + "("
+ COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ MARKET + " TEXT, "
+ PRODUCT + " TEXT)");
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME + "");
onCreate(db);
}
public Cursor getRecords() {
db = getReadableDatabase();
return db.rawQuery(
"SELECT * FROM " + TABLE_NAME,
null);
}
public void addRecords(String market, String product) {
db = getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(MARKET, market);
contentValues.put(PRODUCT, product);
db.insert(TABLE_NAME, null, contentValues);
db.close();
}
public void deleteRecords(int id){
}}

After couple of days I found solution on my question.If there is better way of doing delete, please post answer.
I added following lines of code:
Main Activity
Cursor cursor = (Cursor) parent.getItemAtPosition(pos);
final int item_id = cursor.getInt(cursor.getColumnIndex("_id"));
databaseHelper.deleteRecords(item_id );
cursor.requery();
DatabaseHelper
public void deleteRecords(int id){
db.delete(TABLE_NAME, COLUMN_ID + "=" + id, null);
}
EDIT:
replaced cursor.requery(); with
shoppingCartAdapter.changeCursor(databaseHelper.getRecords());
because using requery(); is deprecated but both lines of code work.

How to read,add Database into ArrayList?

I'm new to Android Studio here. I don't know how to read and add database into Arraylist . Could you guys please help me with it :P ? I have already tried some methods, but It still didn't work #.# .
public class DatabaseHelper extends SQLiteOpenHelper
{
public static final String DATABASE_NAME = "ToDoList.db";
public static final String TABLE_NAME = "ToDoList_Table";
public static final String DATABASE_TABLE = "ToDo_DBTable";

}
public boolean insertData(String TODO) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(COL_2, TODO);
long result = db.insert(TABLE_NAME, null, contentValues);
if (result == -1)
return false;
else
return true;
}
public ArrayList<String> getRecords(){

Cursor cursor = db.query(TABLE_NAME, new String[]{COL_2},null, null, null, null, null);

return true;
}
return super.onOptionsItemSelected(item);
}
public void onAddItem(View v)
{
aTodoAdapter.add(editTD.getText().toString());
editTD.setText("");
}
}
Here is the picture, it said that Item Inserted but It won't display :'(

Try replacing following code
if(isInserted = true ){
todoItems.add(editTD.getText().toString());
aTodoAdapter.notifyDataSetChanged();
Toast.makeText(MainActivity.this,"Items Inserted",Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(MainActivity.this, "Items not Inserted", Toast.LENGTH_LONG).show();
}
As you need to update adapter as well after adding data to database.

At First change your getRecords() function like below:
public ArrayList<String> getRecords(){
open();
ArrayList<String> data = new ArrayList<>();
Cursor cursor = db.query(DATABASE_TABLE, new String[]{COL_2}, null, null, null, null, null, null);
if (cursor.moveToFirst()){
do {
data.add(cursor.getString(0));
} while (cursor.moveToNext());
}
close();
return data;
}

Deleting from SQL database android

I have a list view and when the user clicks a specific item a contextual action mode is displayed with only one item in it (that is supposed to delete it). However, when I click it, the database is not updated (the item is still on the list). Could anyone help me ?
In MainActivity:
final Context context = this;
ArrayAdapter<String> arrayAdapter;
ArrayList<String> listItems = new ArrayList<String>();
ListView lv;
protected Object mActionMode;
int catPos;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
CategoryDatabase entry = new CategoryDatabase(MainActivity.this);
entry.open();
List<String> all = entry.getAllCategory();
if(all.size()> 0){
lv = (ListView)findViewById(R.id.listView1);
arrayAdapter = new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1, all);
lv.setAdapter(arrayAdapter);
}else{
Toast.makeText(MainActivity.this,"No items to display",Toast.LENGTH_LONG).show();
}
entry.close();
lv.setOnItemLongClickListener(new OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int position, long id) {
catPos = position;
if (mActionMode != null) {
return false;
}
// Start the CAB using the ActionMode.Callback defined above
mActionMode = MainActivity.this
.startActionMode(mActionModeCallback);
view.setSelected(true);
return true;
}
});
}
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_delete_cat:
// shareCurrentItem();
CategoryDatabase entry = new CategoryDatabase(MainActivity.this);
entry.open();
entry.deleteCat(catPos);
List<String> all = entry.getAllCategory();
lv = (ListView)findViewById(R.id.listView1);
arrayAdapter = new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1, all);
lv.setAdapter(arrayAdapter);
entry.close();
mode.finish(); // Action picked, so close the CAB
return true;
default:
return false;
}
}
in Actual Database:
public class CategoryDatabase {
public static final String KEY_ROWID = "_id";
public static final String KEY_CATEGORY = "category";
private static final String DATABASE_NAME = "DBCategory";
private static final String DATABASE_TABLE = "categoryTable";
private static final int DATABASE_VERSION = 1;
private DbHelper ourHelper;
private final Context ourContext;
private SQLiteDatabase ourDatabase;
public CategoryDatabase(Context c){
ourContext = c;
}
public CategoryDatabase open() throws SQLException{
ourHelper = new DbHelper(ourContext);
ourDatabase = ourHelper.getWritableDatabase();
return this;
}
public void close(){
ourHelper.close();
}
private static class DbHelper extends SQLiteOpenHelper{
public DbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
// TODO Auto-generated constructor stub
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" +
KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
KEY_CATEGORY + " TEXT NOT NULL);"
);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE);
onCreate(db);
}
}
public long createEntry(String category) {
ContentValues cv = new ContentValues();
cv.put(KEY_CATEGORY, category);
return ourDatabase.insert(DATABASE_TABLE, null, cv);
}
public List<String> getAllCategory() {
List<String> List = new ArrayList<String>();
// Select All Query
String selectQuery = "SELECT * FROM " + DATABASE_TABLE;
Cursor cursor = ourDatabase.rawQuery(selectQuery, null);
// looping through all rows and adding to list
if (cursor.moveToFirst()) {
do {
List.add(cursor.getString(1));
} while (cursor.moveToNext());
}
return List;
}
public void deleteCat(int catPos) {
ourDatabase.delete(DATABASE_TABLE, KEY_ROWID + "=" + catPos, null);
}
}

Deleting as "entry.deleteCat(catPos);" is not right. If You use Your catPos, which is the position inside the listView, it will not delete the entry from database. You made an INTEGER_PRIMARY_KEY_AUTOINCREMENT inside Your Database, so this Integer will generated automatically and can differ from Your position Integer. What You have to do is, to make a query method inside Your Database where You get even the ID from Your DB-Entry. Then You could call
entry.deleteCat(databaseId);

SQLite android column not found

my code is correct is assume but even though it gives error coloumn not found for _hour & _min:

and the database class is:

}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
onCreate(db);
}
}
is there anything wrong with the SQL exec statement means any space or something?

It looks like you have changed the table schema inside DBHandler#onCreate() after running the app at least once. If so you need to increment DB_VERSION = 2.
The database won't check the code inside onCreate() for a new schema on it's own, you need to tell the database to look for changes after you have made them. The easiest way to do this is by increasing the DB_VERSION.
