I can only get part of a url and put into a String? <p>Ok I wasn't really sure how to word this question, but basically what I want to do is, I got a url from a RSS feed in android, and I need to put part of that url into a string, the url will look something like this: <code>http://www.prsn.uprm.edu/Spanish/Informe_Sismo/myinfoGeneral.php?id=20161206012821'</code> and I only want the part after id= <strong>ONLY THE ID NUMBER</strong>,Then I need the id to put it in the following url: <code>http://shake.uprm.edu/~shake/archive/shake/**ID HERE**/download/tvmap.jpg</code>, to load the image corresponding to the id in Glide: <strong>[Solved]</strong> This Part is solved but i have a other Problem</p> <p>I have to ways to do this</p> <p><strong>First Way:</strong></p> <pre><code> //the original String String somestring = "http://www.prsn.uprm.edu/Spanish/Informe_Sismo/myinfoGeneral.php?id=20161206012821"; //save the index of the string '=' since after that is were you find your number, remember to add one as the begin index is inclusive int beginIndex = somestring.indexOf("=") + 1; //if the number ends the string then save the length of the string as the end, you can change this index if that's not the case int endIndex = somestring.length(); //Obtain the substring using the indexes you obtained (if the number ends the string you can ignore the second index, but i leave it here so you may use it if that's not the case) String theNumber = somestring.substring(beginIndex,endIndex); //printing the number for testing purposes System.out.println("The number is: " + theNumber); //Then create a new string with the data you want (I recommend using StringBuilder) with the first part of what you want StringBuilder sb=new StringBuilder("http://shake.uprm.edu/~shake/archive/shake/"); // add the number sb.append(theNumber); //then the rest of the string sb.append("/download/tvmap.jpg"); //Saving the String in a variable String endResult = sb.toString(); //Verifying end result System.out.println("The end result is: "+endResult); Glide.with(context).load(endResult).into(holder.Thumbnail); </code></pre> <p><strong>Second Way:</strong></p> <pre><code>String url = "http://www.prsn.uprm.edu/Spanish/Informe_Sismo/myinfoGeneral.php?id=20161206012821"; String[] array = url.split("id="); String id = array[1]; String urlToLoad = "http://shake.uprm.edu/~shake/archive/shake/"+id+"/download/tvmap.jpg" Glide.with(context).load(urlToLoad).into(holder.Thumbnail); </code></pre> <p><strong>[Problem]</strong></p> <p>My problem is, if i put the URL normally, ie <code>http://www.prsn.uprm.edu/Spanish/Informe_Sismo/myinfoGeneral.php?id=20161206012821</code> the two methods work for me, but if I get the url Via <code>getLink()</code> does not work for me. <strong>Please help me.<br> I hope I explained well.
