android - ListView Recycle mechanism -

-

I have been very well understood as a ListView recycle mechanism, but I do not understand one thing,

If I want to change the height of the list row, then it only works by determining the height by dynamically, for example: 

  convertView.setLayoutParams (New AbsListView.LayoutParams (AbsListView.LayoutParams.FILL_PARENT, 80));   
 If I define the height of the line layout in XML then it does not change, how is it related to the recycle system?  
 This is not only for list row height, I have seen many cases where the properties of XML are not working, but changing them works dynamically well, but how ?   
 
 
 I understand, it was a small mistake, I 
  •   
      convertView = mInflater.inflate (R. Layout.drawer_list_item, tap, incorrect);   
     above the code was the main reason why the properties of XML were not working. Then I changed it to  
      convertView = mInflater.inflate (R.layout.drawer_list_item, parent, wrong);   
     Now it is working as expected, sorry, but the recycle system has nothing to do with XML, I have lost it there.

    python - Receiving "KeyError" after decoding json result from url -

    -
    I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

    .net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

    -
    "itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
