java - How to get next button in String Array -

in 1 class got string facts in array this:

public class factbook {     public string[] mfacts = {"a", "b", "c"};     .... 

now got random generator this:

public string getfact() {     string fact = "";      random randomgenerator = new random();        int randomnumber = randomgenerator.nextint(mfacts.length);      fact = mfacts[randomnumber];      return fact; } 

my randombutton in activity class this:

final textview factlabel = (textview) findviewbyid(r.id.facttextview); final button showfactbutton = (button) findviewbyid(r.id.showfactbutton); final relativelayout relativelayout = (relativelayout) findviewbyid(r.id.relativelayout); final mediaplayer mmediaplayer = mediaplayer.create(getapplicationcontext(), r.raw.button);  view.onclicklistener listener = new view.onclicklistener() {     @override     public void onclick(view v) {         mmediaplayer.start();          string fact = mfactbook.getfact();         //update label our dynamic fact         factlabel.settext(fact);          int color = mcolorwheel.getcolor();         relativelayout.setbackgroundcolor(color);         showfactbutton.settextcolor(color);     } }; showfactbutton.setonclicklistener(listener); 

now create button goes through array step step (like nextbutton , previousbutton). i'm stuck. has ideas?

create class accepts string array , operate on it, implementation basic, treat poc ;)

public class facts {    private string[] mfacts;    private int current = 0;    public facts( string[] mfacts )    {        this.mfacts = mfacts;    }     public boolean hasprevious()    {       return current >= 0;    }     public boolean hasnext()    {        return current < mfacts.length;    }     public string next()    {        if( !hasnext() )        {             return null;        }        string v = mfacts[ current ];        current++;        return v;    }     public string previous()    {        if( !hasprevious() )        {             return null;        }        string v = mfacts[ current ];        current--;        return v;    }     public string random()    {         random randomgenerator = new random();          int randomnumber = randomgenerator.nextint(mfacts.length);         return mfacts[randomnumber];    } } 

update somewhere in code facts facts = new facts( string[] array ); although not familiar android, see in sources button created in place ( possible gui tool ). on each click on button iterate on array until reaches end. dynamically create button ( read docs ) may use this.

public class buttoncreator {     private facts facts;     public buttoncreator( facts facts )     {         this.facts = facts;     }      public boolean cancreatenextbutton() { return facts.hasnext(); }     public boolean cancreatepreviousbutton() { return facts.hasprevious(); }     public button createnextbutton( context context )     {         button button = new button( context );         button.settext( facts.next() );         return button;     }     public button createpreviousbutton( context context )     {         button button = new button( context );         button.settext( facts.previous() );         return button;     } } 

then after creation setup appropriate listener in pasted code

then during initialization of form

string[] arr = {"aaa","bbbb","ccc"}; facts f = new facts( array ); buttoncreator creator = new buttoncreator( f );  while( creator.cancreatenextbutton() ) {     button button = creator.nextbutton( //view context here// );     button.setlistener( //listener here// );     }
