java - Having issues with argb method with Android -

i trying figure out how use argb method http://developer.android.com/reference/android/graphics/color.html.

i've read through multiple times , still can't app work. i'm trying view widget display color made moving 4 sliders no colors show no matter put sliders. thought argb method return value colorvalue , able use color? suggestions appreciated!

my main class looks this:

public class colorchooseractivity extends activity implements onseekbarchangelistener {     //variables private seekbar redseekbar; private seekbar greenseekbar; private seekbar blueseekbar; private seekbar alphaseekbar; private view colorview; private textview colortextview;  //instanced variables private static int colorvalue = 0; private int redvalue = 0; private int greenvalue = 0; private int bluevalue =0; private int alphavalue =0;   @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_color_chooser);      //reference widgets     redseekbar = (seekbar) findviewbyid(r.id.redseekbar);     greenseekbar = (seekbar) findviewbyid(r.id.greenseekbar);     blueseekbar = (seekbar) findviewbyid(r.id.blueseekbar);     alphaseekbar = (seekbar) findviewbyid(r.id.alphaseekbar);     colorview = (view) findviewbyid(r.id.colorview);     colortextview = (textview) findviewbyid(r.id.colortextview);      //listener     redseekbar.setonseekbarchangelistener(this);     greenseekbar.setonseekbarchangelistener(this);     blueseekbar.setonseekbarchangelistener(this);     alphaseekbar.setonseekbarchangelistener(this); }  @override public void onprogresschanged(seekbar seekbar, int progress,              boolean fromuser) {     int redvalue = redseekbar.getprogress();     int greenvalue = greenseekbar.getprogress();     int bluevalue = blueseekbar.getprogress();     int alphavalue = alphaseekbar.getprogress();      argb(alphavalue, redvalue, greenvalue, bluevalue);      colorview.setbackgroundcolor(colorvalue);      string rgbvalue = integer.tostring(progress);      colortextview.settext(rgbvalue);  } @override  public void onstarttrackingtouch(seekbar seekbar) { } @override public void onstoptrackingtouch(seekbar seekbar){ }  public static int argb (int alpha, int red, int green, int blue){     return colorvalue;  } 

}

your colorvalue 0!

replace argb(alphavalue, redvalue, greenvalue, bluevalue);

by colorvalue = argb(alphavalue, redvalue, greenvalue, bluevalue);

edit:

i realized now: argb method nothing! don't make proper use of parameter!

replace by:

public int argb (int alpha, int red, int green, int blue) {     return color.argb(alpha, red, green, blue); }
