java - change corner radius of drawable programmatically -


मुझे यह आकार एक XML में परिभाषित किया गया है: 

  & lt;? Xml version = " 1.0 "एन्कोडिंग =" यूटीएफ -8 "? & Gt; & Lt; आकार xmlns: एंड्रॉइड = "http://schemas.android.com/apk/res/android" एंड्रॉइड: आकृति = "आयत" & gt; & Lt; ढाल एंड्रॉइड: startColor = "# FFFF0000" एंड्रॉइड: एंडColor = "# 80FF00FF" एंड्रॉइड: एंगल = "45" / & gt; & Lt; padding android: left = "7dp" android: top = "7dp" एंड्रॉइड: right = "7dp" एंड्रॉइड: bottom = "7dp" / & gt; & LT; कोनों एंड्रॉयड: bottomLeftRadius = "5dp" ## इस एंड्रॉयड बदलने की जरूरत: topLeftRadius = "5dp" ## इस एंड्रॉयड बदलने की जरूरत: bottomRightRadius = "5dp" ## इस एंड्रॉयड बदलने की जरूरत topRightRadius = "5dp" / & gt; ## इस जरूरत को बदलने & lt; / shape & gt;   
 मैं निम्नलिखित वस्तु बनाने हूँ:।  
 <कोड> Drawable आकार = getResource () getDrawable (R.drawable.myshape);   
 और मुझे इसकी त्रिज्या को संशोधित करने की आवश्यकता है (या एक और कोने त्रिज्या के साथ एक बनाओ)।  
 मैं त्रिज्या कैसे बदल सकता हूँ? कैसे मैं आकार प्रोग्राम के रूप में बना सकते हैं?   
 
 
 मैं मेरी समस्या हल। यहाँ समाधान है:  
  निजी Drawable getShape () {GradientDrawable gradientDrawable = नए GradientDrawable (GradientDrawable.Orientation.TL_BR, नई पूर्णांक [] {startColor, centerColor, endColor}); gradientDrawable.setGradientType (GradientDrawable.LINEAR_GRADIENT); gradientDrawable.setCornerRadii (getRandomFloatArray ()); ग्रेडिएंट ड्रेवायबल .सेटग्रेडिएन्ट सेंटर (0.0 एफ, 0.45 एफ); रिटर्न ग्रेडिएंट ड्रॉएबल; } निजी फ्लोट [] getRandomFloatArray () {यादृच्छिक rnd = नया रैंडम (); फ्लोट [] फ़्लोट्स = नया फ्लोट [8]; के लिए (इंट i = 0; i & lt; floats.length; i ++) {फ्लोट [i] = rnd.nextInt (45); } वापसी फ्लोट; }

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
