equation - how to show fraction with denomainator, horizantal line and numerator on run time in android -

is there any why show fraction neat , clean in android denominator, horizontal line , numerator

for example

4/5+x + 3

would be

4
_____ + 3

5 + x

actually want show algebraic equation on run time.

please tell me answer working on since 4 or 5 days no success achieved.

try this:

mainactivity code:

public class mainactivity extends activity {

edittext etinput; linearlayout resultlayout; button btnresult; viewtreeobserver mvto; int widthofline;   @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      etinput = (edittext) findviewbyid(r.id.etinput);     btnresult = (button) findviewbyid(r.id.btnshowres);     btnresult.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {              string temp = etinput.gettext().tostring().trim();              if(temp.contains("/")){                 system.out.println("inside if");                 string[] numarr = temp.split("/");                 log.d("dj", "num1: & num2: "+numarr[0]+" "+numarr[1]);                 showresults(numarr[0], numarr[1]);             }             else toast.maketext(getbasecontext(), "pattern invalid", toast.length_short).show();           }     });      resultlayout = (linearlayout) findviewbyid(r.id.showresultlay);  }      protected void showresults(string numerator, string denominator) {      final linearlayout linchild = new linearlayout(getbasecontext());      linearlayout.layoutparams childparams = new linearlayout.layoutparams(layoutparams.wrap_content,layoutparams.wrap_content);     linchild.setgravity(gravity.center);     linchild.setlayoutparams(childparams);     linchild.setorientation(linearlayout.vertical);       textview tvnumerator = new textview(getbasecontext());     linearlayout.layoutparams tvparams = new linearlayout.layoutparams(layoutparams.wrap_content,layoutparams.wrap_content);     tvnumerator.setlayoutparams(tvparams);     linchild.addview(tvnumerator);      tvnumerator.settext(numerator);     tvnumerator.settextcolor(color.black);     tvnumerator.settextsize(25);      final view dividerview = new view(getbasecontext());     dividerview.setbackgroundcolor(color.red);     linchild.addview(dividerview);       final textview tvdenominator = new textview(getbasecontext());     linearlayout.layoutparams tv1params = new linearlayout.layoutparams(layoutparams.wrap_content,layoutparams.wrap_content);     tvdenominator.setlayoutparams(tv1params);     linchild.addview(tvdenominator);     tvdenominator.settextcolor(color.black);     tvdenominator.settext(denominator);     tvdenominator.settextsize(25);      mvto = linchild.getviewtreeobserver();     mvto.addongloballayoutlistener(new ongloballayoutlistener() {          @override         public void ongloballayout() {              widthofline = tvdenominator.getwidth();             linearlayout.layoutparams viewparams = new linearlayout.layoutparams(layoutparams.wrap_content, 5);             viewparams.width = widthofline;             dividerview.setlayoutparams(viewparams);          }     });      resultlayout.addview(linchild);  } 

}
