random genaration of image from drawable folder in android -

-

Android version: 4.2
I'm developing Android app. I need to create a picture randomly from the drawable folder. In my picture, I have 45 images, which are different names. My XML code: 

  Android: Image = "@ + ID / Image View 1" Android: layout_width = "wrap-content" Android: layout_height = "wrap_content" />   
 I have tried with this code:  
  ImageView img = (ImageView) findViewById (R.id.imageView1); Random rand = new random (); Int rndInt = rand.nextInt (52) + 1; String Drawable name = "photo" + rndInt; Int resID = getResources (). GetIdentifier (drawableName, "drawable", getPackageName ()); Img.setImageResource (Resid);   
 But with this code I have to change my image names to  photo1 ,  photo2  and I do not want to do this for.  
 Any suggestions about applying it? Thank you.  
  
 
 
 One way to create an array with the required image ID and take random one from that array That approach is explained in the other answer.  
 Another way is to enter the  random_images_array.xml  in the  value  folder of your project and fill it like this:  
 < Code> & lt ;? Xml version = "1.0" encoding = "UTF-8"? & Gt; & Lt; Resources & gt; & Lt; Array name = "epiphur" & gt; & Lt; Items & gt; @ Drawable / IMAGE_1 & lt; / Item & gt; & Lt; Items & gt; @ Drawable / photo_2 & lt; / Item & gt; & Lt; Items & gt; @ Drawable / picture_4 & lt; / Item & gt; & Lt; / Array & gt; & Lt; / Resources & gt;   
 And then you can take a random image from that XML array:  
  last typedArray = getResources (). GetTypedArray (R.array.random_images_array); Final Random = New Random (); Final int rndInt = rand.nextInt (imgs.length ()); Final integer resID = imgs.getResourceId (rndInt, 0);   
 The third method is to take random areas from the R.Drawable class:  
  final range drawableClass = R.drawable.class; Last field [] field = drawable class .getFields (); Final Random = New Random (); Int rndInt = rand.nextInt (fields.length); {Int resID = field [rndInt] Try .getInt (drawableClass); Img.setImageResource (Resid); } Hold (exception e) {e.printStackTrace (); }

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
