Android App: Error: Android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0

I have a problem, you can see below. Please, help me. I am beginner in Android App. Thank you in advance for your help. I am getting the following error:

Your cursor is empty. You can't read any data from an empty cursor, hence the exception.
Both, moveToFirst() and moveToNext() will return false if the move did not succeed. You're ignoring the result of moveToFirst() and try reading from the cursor leading to the exception.

When you use a database, it is best to check for records before looping to retrieve them (if any).
The best way to do this is to use the getCount method of the Cursor class.
Cursor c = db.rawQuery(String.format("SELECT * FROM Otazky ORDER BY Random() LIMIT %d", konec), null);
if (c != null && c.getCount() > 0) {
/* Code Here */
}

Error when trying to use cursor to get integer values from SQLite in Android

I'm trying to get integer values, to be displayed in a listview from SQLlite using cursors but it shows the following error:
java.lang.IllegalStateException: Couldn't read row 0, col 4 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it.
Here are my code
MyItems.java:
public ArrayList<SalesItemInformationLV> retrieveAllForlist(Context c)
{
ArrayList<SalesItemInformationLV> items = new ArrayList<SalesItemInformationLV>();
Cursor myCursor;
String mystring = "";
MyDbAdapter db = new MyDbAdapter(c);
db.open();
//contactIdList.clear();
//contactList.clear();
myCursor = db.retrieveAllEntriesCursor();
if (myCursor != null && myCursor.getCount() > 0)
{
myCursor.moveToFirst();
do {
contactIdList.add(myCursor.getInt(db.COLUMN_KEY_ID));
items.add(new SalesItemInformationLV(myCursor.getString(db.COLUMN_NAME_ID), myCursor.getInt(db.COLUMN_QTYSOLD_ID)));
} while (myCursor.moveToNext());
}
db.close();
return items;
}
MyDbAdapter.java:
private SQLiteDatabase _db;
private final Context context;
public static final String KEY_ID = "_id";
public static final int COLUMN_KEY_ID = 0;
public static final String ENTRY_NAME = "entry_name";
public static final int COLUMN_NAME_ID = 1;
public static final String ENTRY_QTYSOLD = "entry_qtysold";
public static final int COLUMN_QTYSOLD_ID = 4;
private MyDBOpenHelper dbHelper;
//private MyDBOpenHelper dbHelper2;
public MyDbAdapter(Context _context)
{
this.context = _context;
//step 16 - create MyDBOpenHelper object
//constructor
dbHelper = new MyDBOpenHelper(context, DATABASE_NAMEA, null, DATABASE_VERSION);
//constructor
//dbHelper2 = new MyDBOpenHelper(context, DATABASE_NAME2, null, DATABASE_VERSION);
}
public Cursor retrieveAllEntriesCursor() {
//step 21 - retrieve all records from table
Cursor c = null;
try {
c = _db.query(DATABASE_TABLE, new String[] {KEY_ID, ENTRY_NAME}, null, null, null, null, null);
}
catch (SQLiteException e)
{
Log.w(MYDBADAPTER_LOG_CAT, "Retrieve fail!");
}
return c;
}
I suspect the error comes from MyItems.java, but I'm having a hard time figuring out what's the error.

Seems like you are fetching only 2 columns(KEY_ID, ENTRY_NAME) from database and while reading you are expecting 3 columns.
c = _db.query(DATABASE_TABLE, new String[] {KEY_ID, ENTRY_NAME}, null, null, null, null, null);
You are trying to get value from column 4, which is throuing an error.
public static final int COLUMN_QTYSOLD_ID = 4;

Use this method in your databasehelper class
public Cursor getalldata() {
SQLiteDatabase db = this.getWritableDatabase();
Cursor res = db.rawQuery(" select * from " + TABLE_Name, null);
return res;
}
**and call this method where you want to get your data from database table **
public void getdata(){
Cursor res = db.getstafdata(); //db id an object of database helper //class
if (res.getCount() == 0) {
Toast.makeText(getApplicationContext(),
"no data", Toast.LENGTH_LONG).show();
} else {
StringBuffer stbuff = new StringBuffer();
while (res.moveToNext()) {
detail.add(new doctor_details(res.getString(1),res.getString(2),res.getString(3)));
}
}
}

Saving elements in SQLite Android

I want to save DatabaseTableDay to my SQLite in anndroid applicatin but something gones wrong.
My DatabaseDAODay is:
public class DatabaseDAODay {
public static final String TAG = "DaysDAO";
// Database fields
private SQLiteDatabase mDatabase;
private DatabaseHelper mDbHelper;
private Context mContext;
private String[] mAllColumns = { DatabaseHelper.COLUMN_DAY_ID,
DatabaseHelper.COLUMN_DAY_NAME, DatabaseHelper.COLUMN_DAY_WEIGHT};
public DatabaseDAODay(Context context) {
this.mContext = context;
mDbHelper = new DatabaseHelper(context);
// open the database
try {
open();
} catch (SQLException e) {
Log.e(TAG, "SQLException on openning database " + e.getMessage());
e.printStackTrace();
}
}
public void open() throws SQLException {
mDatabase = mDbHelper.getWritableDatabase();
}
public void close() {
mDbHelper.close();
}
public DatabaseTableDay createDay(String name, float weight, Long id) {
ContentValues values = new ContentValues();
values.put(DatabaseHelper.COLUMN_DAY_NAME, name);
values.put(DatabaseHelper.COLUMN_DAY_WEIGHT, weight);
long insertId = id;
Cursor cursor = mDatabase.query(DatabaseHelper.TABLE_DAYS, mAllColumns,
DatabaseHelper.COLUMN_DAY_ID + " = " + insertId, null, null,
null, null);
DatabaseTableDay newDay = new DatabaseTableDay();
if(cursor != null && cursor.moveToFirst()){
newDay = cursorToDay(cursor);
cursor.close();
Toast.makeText(mContext,"im here",Toast.LENGTH_LONG).show();
}
return newDay;
}
public void deleteDay(DatabaseTableDay databaseTableDay) {
long id = databaseTableDay.getId();
// delete all employees of this company
DatabaseDAOActivity databaseDAOActivity = new DatabaseDAOActivity(mContext);
List<DatabaseTableActivity> databaseTableActivities = databaseDAOActivity.getActivitiesOfDay(id);
if (databaseTableActivities != null && !databaseTableActivities.isEmpty()) {
for (DatabaseTableActivity e : databaseTableActivities) {
databaseDAOActivity.deleteActivity(e);
}
}
System.out.println("the deleted day has the id: " + id);
mDatabase.delete(DatabaseHelper.TABLE_DAYS, DatabaseHelper.COLUMN_DAY_ID
+ " = " + id, null);
}
public List<DatabaseTableDay> getAllDays() {
List<DatabaseTableDay> listDays = new ArrayList<DatabaseTableDay>();
Cursor cursor = mDatabase.query(DatabaseHelper.TABLE_DAYS, mAllColumns,
null, null, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
DatabaseTableDay day = cursorToDay(cursor);
listDays.add(day);
cursor.moveToNext();
}
// make sure to close the cursor
cursor.close();
}
return listDays;
}
public DatabaseTableDay getDayById(long id) {
Cursor cursor = mDatabase.query(DatabaseHelper.TABLE_DAYS, mAllColumns,
DatabaseHelper.COLUMN_DAY_ID + " = ?",
new String[] { String.valueOf(id) }, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
}
DatabaseTableDay databaseTableDay = cursorToDay(cursor);
return databaseTableDay;
}
protected DatabaseTableDay cursorToDay(Cursor cursor) {
DatabaseTableDay databaseTableDay = new DatabaseTableDay();
databaseTableDay.setId(cursor.getLong(0));
databaseTableDay.setName(cursor.getString(1));
databaseTableDay.setWeight(cursor.getLong(2));
return databaseTableDay;
}
}
and I try to save it by:
saveButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DatabaseTableDay databaseTableDay = databaseDAODay.createDay(
editText.getText().toString(), 100f, new Long(myId));
List<DatabaseTableDay> list = databaseDAODay.getAllDays();
}
});
but list is empty anyway.
Probably the problem is createDay() method in DatabaseDAODay because if condition is always null and application doesn' run cursorToDay() method.
I had problem without condition and if there was only cursot.moveToFirst() and then cursorToDay() there was NullPoinerException - because coursor was null. I followed this and put condition !=null but actually nothing happens and List is always empty...
How should I solve my problem?

You are right about the problem being createDay(): instead of inserting a new day by using insert() you try to read from the database by using query()
Change your method like this:
public DatabaseTableDay createDay(String name, float weight, Long id) {
DatabaseTableDay dayToReturn;
ContentValues values = new ContentValues();
values.put(DatabaseHelper.COLUMN_DAY_NAME, name);
values.put(DatabaseHelper.COLUMN_DAY_WEIGHT, weight);
values.put(DatabaseHelper.COLUMN_DAY_ID, id);
long resID = mDatabase.insert(DatabaseHelper.TABLE_DAYS, null, values);
if (resID == -1)
{
// something went wrong, do error handling here
dayToReturn = null;
}
else
{
// no error: resID is "the row ID of the newly inserted row"
// you only need this info if you are using autoincrement
// not if you set the ID yourself
// all right, this will work -
// but somehow it hurts a little to retrieve an entry I just added.
// I'd like much more to simply use a constructor with all the values
// and create a new DatabaseTableDay instance
dayToReturn = getDayById(id);
}
return dayToReturn;
}

how to display images from sqlite through drawable

I'm not sure of the exact details here but basically, if you want to store images in your database you must store the information as a 'blob' of bytes.
You'll need to convert between bytes and Bitmap when you read from the DB and Bitmap and bytes when you want to write to the DB.
A URI is usually used for a file coming from your device storage or somewhere on a server/website etc.
If this is what you're looking for and you'd like more detailed help just let me know and I can provide more info.

In SimpleCursorAdapter.java, you have a method bindView() which overrides the same method from its parent class, but you don't put any code in that method. Deleting the method should fix the error. But if you plan to override how binding works in that method, you may want to put some code in there starting with something like
super.bindView(view, context, cursor);
