try thing below :

 button=(button)vi.findviewbyid(r.id.button_save);          button.setonclicklistener(new onclicklistener() {    private bitmap bm;   private string prefs_name; public void onclick(view arg0) {     string root = environment.getexternalstoragedirectory().tostring();        file mydir = new file(root + "/saved_images");        if(!mydir.exists()){            mydir.mkdirs();}        bm = bitmapfactory.decoderesource( mcontext.getresources(), images[itempos]);          holder.image.setimagebitmap(bm);          sharedpreferences savednumber = mcontext.getsharedpreferences(prefs_name, 0);          int lastsavednumber = savednumber.getint("lastsavednumber",0);          lastsavednumber++;          string fname = "image-"+lastsavednumber+".png";           file file = new file (mydir, fname);          if (file.exists ()) {file.delete (); }          try {          fileoutputstream out = new fileoutputstream(file);          bm.compress(bitmap.compressformat.png, 100, out);//your bitmap resouce          out.flush();          out.close(); }          catch (exception e) {          e.printstacktrace();          }           sharedpreferences savenumber = mcontext.getapplicationcontext().getsharedpreferences(prefs_name, 0);          sharedpreferences.editor editorset = savenumber.edit();          editorset.putint("lastsavednumber",lastsavednumber);          editorset.commit();           toast.maketext(mcontext, "saved", toast.length_short). show();}}); 

hope you.
