I recently started working with dynamic listview items. It's great except for when I try to add and clear items with bitmaps. I have a listview where I add items and download the image into a memstream and assign it to the bitmap of the dynamic listview item. This works except for when I go and clear all the items with lv.items.clear it does not get removed from memory.

The memory just keeps rising even though I clear the old items. Is there a ways to clear all the bitmaps?

Basically what happens is:

1. Populate dynamic listview with 10 items. Add data and bitmaps.
2. Look at memory. Went up with 2 megabytes.
3. Clear the listview with lv.items.clear.
4. Look at memory. No change?
5. Repeat and the memory just goes up and up.

I have tried looping through all the listview items and setting each bitmap to nil but no result in any memory change. I also tried freeing each item by looping through it but it just crashes the app.

Should I be clearing all the items or bitmaps in a way? If so how can I go about doing that?

Here's how I'm loading all of the items:

I just tried to run the code below. I got no error message, but no data was actually written to the CSV. I looked at the website and I found both snapshot-td2-cp and snapshot-td2 elements. When I remove the writer.writerow statements and use print statements, I see six number 2 characters, and that's it.

Here is the code that I am testing.

I have below text content in a variable called text

Logic :

• When combining the content with the content to generate the content for the CXML, only the differing numbers should be included. For example, in the code sample, the element is 1545 and the element is 1547, making only the final digit (7) different, so the resulting content should be 1545–7. However, if the content was 1557, then the result would be 1545–57.

How to shift key in to values and index as key in dictionary. I wrote the program and working fine. But i need to do enumerate the output and shift the key to value and make index number as my key

I am making a python log parser script where I need to print Ip the after 2 consecutive 403

I am making a Python script to parse logs and count the number of times that GET, POST, 200, and 404 occur for each IP address in the log.

Example of log file:

In my app, I send a volley request which fetches list items one-by-one, not all at once. I want to implement a progressbar at the end of the recyclerview when the data is being fetched. The class 'updateAdapter' updates the adapter and I was thinking of making the progress bar visible in the recyclerview scroll listener. But I have no idea how to do this in my code.
