Putting cursor data into an array

Question

Being new in Android, I am having trouble dealing with the following:

public String[] getContacts(){
    Cursor cursor = getReadableDatabase().rawQuery(\"SELECT          


        

Answer 1

names.add(cursor.getString(i));

"i" is not the cursor row index, it's the column index. A cursor is already positioned to a specific row. If you need to reposition your cursor. Use cursor.move or moveToXXXX (see documentation).

For getString/Int/Long etc. you just need to tell the cursor which column you want. If you don't know the columnIndex you can use cursor.getColumnIndex("yourColumnName").

Your loop should look like this:

public String[] getContacts(){
    Cursor cursor = getReadableDatabase().rawQuery("SELECT name FROM contacts", null);
    cursor.moveToFirst();
    ArrayList names = new ArrayList();
    while(!cursor.isAfterLast()) {
        names.add(cursor.getString(cursor.getColumnIndex("name")));
        cursor.moveToNext();
    }
    cursor.close();
    return names.toArray(new String[names.size()]);
}
