How do i order my SQLITE database in descending order, for an android app?

Question

What is the most efficient method of showing my data in descending order?

public String getRank() {

    String[] rank = new String[]{ KEY_ROWID };
    Curso         


        

Answer 1

public List getExpensesList(){
    SQLiteDatabase db = this.getWritableDatabase();

    List expenses_list = new ArrayList();
    String selectQuery = "SELECT * FROM " + TABLE_NAME ;

    Cursor cursor = db.rawQuery(selectQuery, null);
    try{
        if (cursor.moveToLast()) {

            do{
                String info = cursor.getString(cursor.getColumnIndex(KEY_DESCRIPTION));
                expenses_list.add(info);
            }while (cursor.moveToPrevious());
        }
    }finally{
        cursor.close();
    }
    return expenses_list;
}

This is my way of reading the record from database for list view in descending order. Move the cursor to last and move to previous record after each record is fetched. Hope this helps~
