Which is more expensive, notifyDatasetChanged() or looping over a large cursor?

问题 Basically, I have a RecyclerView with an adapter populating the data from a cursor. I have two options to get item animations: Use setHasStableIds(true) and override getItemId to return the ID of the database row, and then use a swapCursor function in the adapter that swaps its current cursor with the new one and then calls notifyDatasetChanged Similar to option 1, but instead of simply swapping the cursor and calling notifyDatasetChanged , iterate over the old and new cursor, comparing the

问题 I asked a question yesterday here about having a cursor that changes regularly using javascript, to make it look animated. I got a great answer (Thank you Shiva!). I've now been trying to get two different 'animated' cursors, one for the 'auto' cursor, and a different one for the 'pointer' cursor. I tried it lots of different ways, but just can't work it out (I must admit, I'm completely new to this - trying to improve). Here's one of the ways I tried to do it: <!DOCTYPE html> <html> <head>

[亡魂溺海] 提交于 2019-12-25 05:01:24
问题 I am storing a Bitmap in the SD card of the mobile, then I have another method that lists all File present in the folder where I saved my Bitmap. The problem is that when the images are stored, and even though I checked whether they are really present in the folder, my codes to list images from that folder doesn't return those images, it usually shows them after a few times I utilise the app though. Can anyone help me with this? You can find my codes below. This is for storing the Bitmap

Python wrapper preventing function call?

问题 I've written a bunch of helper functions to wrap common functions such as insert and select. Included below is just one of those wrappers... which I can't seem to figure out why it isn't working. I suspect it is something to do with the wrapper: from collections import Mapping import sqlite3 def counter(func): def wrapper(*args, **kwargs): wrapper.count = wrapper.count + 1 wrapper.count = 0 return wrapper @counter def insert(val, cursor, table="reuters_word_list", logfile="queries.log"): if

change hotspot of a custom cursor

时间秒杀一切 提交于 2019-12-25 04:59:08
问题 I'm using a custom cursor that I loaded in this way: Bitmap bit = new Bitmap(path); cur = new Cursor(bit.GetHicon()); Cursor.current = cur; my bitmap is a 44x58 png and the mouse hot spot is not exactly where I want to be. I looked for a property to change the mouse hot spot but the only one I found is readable-only ( cur.Hotspot ). What I need to do for change its coordinates? Thanks 回答1: In Visual Studio, open the cursor file or resource in the image editor and select the Hotspot Tool from

Sending an Array into a PL/SQL Procedure

偶尔善良 提交于 2019-12-25 04:33:45
问题 I have created a Web Service to send in a bunch of information to a PL/SQL procedure, however one of them is a array. What type do I use for this? I also want to put that array into a cursor after it comes in. 回答1: I don't have any experience with PL/SQL, so sorry if this doesn't apply. In MS SQL 2000/2005, there isn't a way to pass arrays into a procedure; I'm assuming PL/SQL has a similar limitation. The workaround I've used in the past is to pass in a delimited string (usually pipe

Is it possible to retrieve an object that is split into three tables with only one query?

我是研究僧i 提交于 2019-12-25 03:47:16
问题 EDIT : The answers works, but slow down the query a lot. Is there another solution? I have the following object in my program. Page haves various TextBlock that haves various Token . The three are stored in the database in three tables with the same namas of the objects. I want to know if is possible to recover all the data needed to fill the object in the program with only one query. I want only one query because I'm using a CURSOR to iterate over all the objects stored in the database. The
