android - Why do some images display black when loading data from a url? -

-

I am downloading images from a URL and storing them in a SQLite database table. Pictures are profile pictures for users. I store the image of the profile and the user's information in one line.

It mostly works almost all the images are loaded properly in my list However, I have around 300 users who are displayed with a black image. I have verified that by downloading the image through my web browser, users with black images on the URL hold a valid image.

Has anyone ever noticed why some of these users are showing a black image? I do not see any exception.

Here is my code: 

  byterefer buff = new bytereferver (50); URL url = new URL (imageURL); URLConnection ucon = url.openConnection (); InputStream = ucon.getInputStream (); BufferedInputStream bis = new BufferedInputStream (is); Int current = 0; While ((current = bis.read ())! = -1) {baf.append (byte) on); }   
 ...  
  // Then byte [] is stored in a SQLite Blob field. Baf.toByteArray ()     
  // Then I'm loading the Blob field in my view like this byte [] bytes = Cursor.gateblob (cursor.gate column index (on db.char.profile_IMAGE_COLUMN)); If (byte! = Null) {ImageView iv = (ImageView) v.findViewById (RID.profile_corean); Iv.setImageBitmap (BitmapFactory.decodeByteArray (bytes, 0, bytes length)); }    
 
 
 A black image is usually a problem with alpha mixed / semi The symptom is the transparent picture I will manually download one of those pictures and to check it with some image editing application it will be detected as the exact format of that image.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
