Issue related to using Android attribute (attr) defined in other aar package -

-

मान लें कि attr को aar पैकेज में परिभाषित किया गया है ( Com.pack1 ) के रूप में 

  & lt; attr name = "attr0" format = "string" / & gt;

और दूसरे पैकेज में ( com.pack2 पर com.pack1 पर निर्भरता है, कहें)) मैं एक styleable < / कोड> के रूप में 

  & lt; attr name = "attr2" format = "integer" / & gt; & Lt; घोषित-शैली योग्य नाम = "दृश्य 2" & gt; & Lt; attr name = "attr1" format = "string" / & gt; & Lt; attr name = "attr2" / & gt; & Lt; / घोषित-Styleable & gt;

और मेरे पास com.pack2 के रूप में एक कस्टम दृश्य है 

  सार्वजनिक वर्ग View2 LinearLayout {सार्वजनिक View2 (संदर्भ संदर्भ , AttributeSet attributeSet) {सुपर (संदर्भ, विशेषता सेट); View.inflate (संदर्भ, R.layout.view2, यह); कोशिश करें {टाइप किए गएअरे टाइप कियाअरेरे = संदर्भ। शौकीन स्टाइल गुण (विशेषतासैट, आर। स्टेलेबल.विवरण 2); {If (typedArray.hasValue (R.styleable.view2_attr1)) {String t = typedArray.getString (R.styleable.view2_attr1); Logger.debug ("attr1 - & gt; मूल्य है - & gt; {}", टी); } Else logger.debug ("attr1 - & gt; कोई मान नहीं"); यदि (टाइप कियाअरेरेएचएएसएवल्यू (आर.स्टेबल। वीवी 2_टाट्र 2)) {int t = typedArray.getInteger (R.styleable.view2_attr2, 0); Logger.debug ("attr2 - & gt; मूल्य है - & gt; {}", t); } Else logger.debug ("attr2 - & gt; कोई भी मान नहीं"); } TypedArray.recycle (); } कैच (थ्रोहेबल टी) {लॉगर। डीबग (टी.ओस्टस्ट्रिंग ()); }}}

और मैं एक कस्टम लेआउट को 

  & lt; LinearLayout xmlns के रूप में जोड़ता हूं: एंड्रॉइड = "http://schemas.android Com / apk / res / android "xmlns: custom =" http://schemas.android.com/apk/res-auto "एंड्रॉइड: अभिविन्यास =" लंबवत "एंड्रॉइड: layout_width =" fill_parent "एंड्रॉइड: layout_height =" fill_parent " & gt; & Lt; com.pack2.View2 android: layout_width = "fill_parent" एंड्रॉइड: layout_height = "wrap_content" कस्टम: attr1 = "यह एक परीक्षा है" कस्टम: attr2 = "1000" / & gt; & Lt; / LinearLayout & gt;

यहां तक ​​कि जब मैं ऐप चलाता हूं तो सबकुछ ठीक होता है और लॉगगर की रिपोर्ट है कि 

  attr1 - & gt; मूल्य है - & gt; यह एक परीक्षण एट्रेट 2 - & gt; मूल्य है - & gt; 1000

लेकिन जैसे ही मैं styleable जैसा 

  & lt; attr name = "attr2" format = "integer बदलता हूं "/ & Gt; & Lt; घोषित-शैली योग्य नाम = "दृश्य 2" & gt; & Lt; attr name = "attr0" / & gt; & Lt; attr name = "attr1" format = "string" / & gt; & Lt; attr name = "attr2" / & gt; & Lt; / घोषित-Styleable & gt;

और एप को चलाने के लिए मुझे गलत परिणाम मिलते हैं I लॉगगर की रिपोर्ट है कि 

  attr1 - & gt; कोई मान

और कोई अपवाद हुआ 

  java.lang.UnsupportedOperationException: पूर्णांक में कनवर्ट नहीं किया जा सकता: प्रकार = 0x3

यह मान की तरह लग रहा है "यह एक परीक्षा है" attr0 के लिए उपयोग किया जाता है, हालांकि उस विशेषता को लेआउट में परिभाषित नहीं किया गया है। ध्यान दें कि ऐप ठीक से संकलित हो जाता है, लेकिन परिणाम गलत है।

मुझे ऐसा क्यों मिलता है?

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
