android - updating listview after inserting row via content provider -

-

I am using custom ContentProvider to enter and query SQLite database in Android. When I query from the database, I am populating the data on the listview but this problem occurs when I include that row which I also want to update the list view. Custom Adapter is created by increasing Cursor Adapter and LoaderManager.Loader Callbacks , now when I Context.getContentResolver (). Insert () function, I want to update listview

I have tried adapter.notifyDataSetChanged (); After adding the row, but the listview is not updating.

There is only one option I have seen RestartLoader () Any other watt to update the list view?

This is my insert code 

  context.getContentResolver (). Insert (ContentUris.withAppendedId (URI.) Expected word (column CONTENT_URI, Columns.INSERT_LOGS), column .LOGS), value);   
 I am including the log of the application and showing in the list view  
 here is the code inside the content provider  
  If (rowId> 0) {Ury DartURI = Content uris With expected command (columncontronus, line id); Logs. E ("inserted", line ID + ""); . GetContext () getContentResolver () notifyChange (insertUri, tap). Return entry; }    
 
 
 I think, you can see how it works, because it  Loader .  
  
 I had trouble like you and the problem was how I did it.  
 It was exactly like this.  
  @ Override public empty onload loaded (loader & lt; cursor & gt; loader, cursor cursor) {... adapter.swap (cursor) data adapter. NotifyDataSetChanged (); listViewSetAdapter (dataAdapter); ...}

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
