c.getCount() returns 1 because the cursor contains a single row (the one with the real COUNT(*)). The count you need is the int value of first row in cursor.

public int getTaskCount(long tasklist_Id) {

    SQLiteDatabase db = this.getReadableDatabase();
    Cursor cursor= db.rawQuery(
        "SELECT COUNT (*) FROM " + TABLE_TODOTASK + " WHERE " + KEY_TASK_TASKLISTID + "=?",
         new String[] { String.valueOf(tasklist_Id) }
    );
    int count = 0;
    if(null != cursor)
        if(cursor.getCount() > 0){
          cursor.moveToFirst();    
          count = cursor.getInt(0);
        }
        cursor.close();
    }

    db.close();
    return count;
}
