android - Radio button disappeared after placing inside radio group in linear layout -

-

I have to take two radio buttons that are horizontally used, but I have a problem which is both radio buttons Getting is chosen instead of normal behavior, where any radio button should be selected ... so I used the radio group inside a linear layout horizontal But surprisingly all the radio buttons disappeared. No clue .. 

  Android: Leaut_vind = "L50dip" Android: layout_height = "22dip" android: background = "@ color / silver" android: orientation = "horizontal" & gt; Android; Radio Group Android: ID = "@ + ID / Radiography" Android: Layout_Wind = "150 DP" Android: Layout_Hypt = "22 DP" Android: Background = "@color / Silver" & gt; Android: layout_weight = "1" Android: text = "/ share" Android: textAppearance = "Android: Android: Android: Android: layout_width =" 0dp "Android: layout_hett =" match_parent ": attr / textAppearanceSmall" /> ; Android: Layout_weight = "1" Android: text = "/ value" android: textAppearance = "? Android: Android: Android: Android: Layout_Wind =" 0 DP ": Attr / textAppearanceSmall" /> & Lt; / RadioGroup & gt; & Lt; / LinearLayout & gt;   
 Enter image details here  
 me This requires  abc   
 to get a radio button below the experts, please help me with this.  
 Thank you for your time  
 Full XML    & lt; linearLayout Android: layout_width = "match_parent" Android: layout_height = "45dp" Android: background = "@color / dark_snf" Android: orientation = "horizontal" & gt; & Lt; LinearLayout Android: layout_width = "150dip" Android: layout_height = "45dp" Android: background = "@color / silver" Android: orientation = "vertical" & gt; Android: layout_heid = "23dip" Android: Android: background = "@color / silver" Android: text = "brokerage" Android: typeface = "Android: serif" Android: text apparatus = "? Android: ATR / Text Appearance Small" /> & Lt; LinearLayout android: layout_width = "150dip" Android: layout_height = "22dip" Android: background = "@color / silver" Android: orientation = "horizontal" & gt; Android; Radio Group Android: ID = "@ + ID / Radiography" Android: Layout_Wind = "150 DP" Android: Layout_Hypt = "22 DP" Android: Background = "@color / Silver" & gt; Android: layout_weight = "1" Android: text = "/ share" Android: textAppearance = "Android: Android: Android: Android: layout_wind =" 0 dip ": Attr / textAppearanceSmall" /> Android: Layout_weight = "1" Android: text = "/ value" android: textAppearance = "? Android: Android: Android: Android: Layout_Wind =" 0 DP ": Attr / textAppearanceSmall" /> & Lt; / RadioGroup & gt; & Lt; / LinearLayout & gt; & Lt; / LinearLayout & gt; Android: Android: Android: layout_heck = "match_perrent" Android: layout_weight = "1" Android: text collar = "@color / white" Android: Android: background = "@draubable / backdrop" Android: Gravity = "center" Android: Typefaces = "Serif" Android: Ams = "10" Android: InputType = "Number Decimal" Android: Text = "0.0" & gt; & Lt; Requestfocus / & gt; & Lt; / EditText> Android: Android: "Gravity =" Center "Android: Text Collar =" @color / Android: Android: Android: Android: Layout_With = "0 DP" Android: Layout_Height = "Match_Part" Android: Layout_Vet = "1.00" Android : Android: Android: Android: @Drawable / Background Android: Typefaces = "Serif" Android: Ams = "10" Android: InfantType = "Number Decimal" Android: Text = "0.0" /> & Lt; / LinearLayout & gt;    
 
 
 Finally I found the answer because I remember  orientation  parameter  radio group  ....  
 this parameter was added  android: orientation = "horizontal"   
 now Android: Android: layout_width = "150dip" Android: layout_height = "22dip" Android: Orientation = "Horizontal" Android: Android: Background =    Android: Android: "@color / silver" & gt;   
 There is no need for  linear layout horizontal

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
