android - Searching ArrayList with user input -

right now, getting list of questions website , putting inside arraylist<string>.

now, how take users input, converted string (ssearchvalue), , check arraylist see if matches? , if finds question contains users search, displays it?

package com.malthorn.anyquestion;  import java.io.ioexception; import java.util.arraylist; import java.util.list;  import android.os.bundle; import android.app.activity; import android.view.menu; import android.view.view; import android.widget.edittext;  import org.jsoup.jsoup; import org.jsoup.nodes.document; import org.jsoup.nodes.element; import org.jsoup.select.elements;  import com.malthorn.gasculator.r;  public class mainactivity extends activity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          document doc;         arraylist<string> urls = new arraylist<string>();         edittext isearchvalue = (edittext) findviewbyid(r.id.iquestion);         string ssearchvalue = isearchvalue.gettext().tostring();          try {              doc = jsoup.connect("http://www.reddit.com/r/askscience/search?q=flair%3a%27psych%27&sort=top&restrict_sr=on").get();              elements links = doc.select("a[href]");             (element link : links) {                 string href1=link.attr("href");                 //                 if(href1.startswith("http://www.reddit.com/r/askscience/"))                  {                     urls.add(link.attr("href"));                  }                  system.out.println("\nlink : " + link.attr("href"));              }          } catch (ioexception e) {             e.printstacktrace();         }     }       @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.main, menu);         return true;     }  } 

public string getquestion(string[] questions, string ssearchvalue){     for(string question : questions){         if(question.equals(ssearchvalue))             return question;     }      return ""; } 

this code searches exact matches, if need find questions ressemble search word adivse on googling method substring type string , uses of regex on pattern matching.
