android-Can't change no of stars in rating bar in alert dialog -

i've used alert dialog star rating bar in it.but can't change number of stars being displayed(now displays 6..i want 5)..

there no corresponding xml rating bar because dynamically made. ive tried setnumstars() method no use....also tried changing wrapcontent.

here code..please help

enter code here  protected void showratingalert() {         // todo auto-generated method stub           alertdialog.builder ab =  new alertdialog.builder(androidloadimagefromurlactivity.this);          ab.settitle("enter rating");ab.setmessage("stars");           final ratingbar rat =  new ratingbar(androidloadimagefromurlactivity.this);          rat.setnumstars(5);          linearlayout.layoutparams lp =  new linearlayout.layoutparams(linearlayout.layoutparams.wrap_content,linearlayout.layoutparams.wrap_content);          rat.setlayoutparams(lp);          ab.setview(rat);          ab.seticon(r.drawable.ic_launcher);          ab.setpositivebutton("ok", new dialoginterface.onclicklistener() {              @override             public void onclick(dialoginterface dialog, int which) {                 // todo auto-generated method stub  float val = rat.getrating();   if(ur.equals("0"))  {     nr = val;  } else {     nr = (art+val)/2;  } 

from ratingbar docs:

sets number of stars show. in order these shown properly, recommended layout width of widget wrap content.

http://developer.android.com/reference/android/widget/ratingbar.html#setnumstars(int)

so in case can create layout, instance layout/rating.xml:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/root"     android:layout_width="wrap_content"     android:layout_height="wrap_content">      <ratingbar         android:id="@+id/ratingbar"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:clickable="true"         android:numstars="5"/>  </linearlayout> 

and use layout dialog context. here modified dialog's code:

protected void showratingalert() {     // todo auto-generated method stub      alertdialog.builder ab =  new alertdialog.builder(androidloadimagefromurlactivity.this);     ab.settitle("enter rating");ab.setmessage("stars");       //inflating layout , finding ratingbar widget     view root = ((layoutinflater) androidloadimagefromurlactivity.this.getsystemservice(context.layout_inflater_service)).inflate(r.layout.rating, null);     ab.setview(root);      final ratingbar rat = (ratingbar)root.findviewbyid(r.id.ratingbar);       rat.setnumstars(5);       ab.seticon(r.drawable.ic_launcher);      //and existing code     ...
