android - Custom RatingBar doesn't work on Dialog -

i have set custom ratingbar style

inside style.xml code:

<item name="android:ratingbarstyle">@style/ratingbarstyle</item> <style name="ratingbarstyle" parent="android:widget.ratingbar">     <item name="android:progressdrawable">@drawable/ratingbar</item>     <item name="android:minheight">13dip</item>     <item name="android:maxheight">13dip</item> </style> 

now have created custom layout dialog (xml) [is inside relativelayout]:

<ratingbar     android:id="@+id/custom_dialog_vota_ratingbar"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_alignleft="@+id/custom_dialog_vota_label_ratingbar"     android:layout_below="@+id/custom_dialog_vota_label_ratingbar"     android:layout_margintop="2dp"     android:max="5"     android:numstars="5"     android:stepsize="0.5" /> 

and on class have code:

public void onclick(view view) {             final dialog dialog = new dialog(mcontext);             dialog.setcontentview(r.layout.custom_dialog_vota);             dialog.settitle("vota");             string t = ((textview)dialog.findviewbyid(r.id.custom_dialog_vota_label_ratingbar)).gettext().tostring();             ((textview)dialog.findviewbyid(r.id.custom_dialog_vota_label_ratingbar)).settext(t + nome_book);             dialog.show();         } 

now ratingbar works fine everywhere, on dialog doesn't work , have no idea why..

edit2 result:
how can see custom ratingbar works on listview or on other activity this:

but on dialog doesn't, , tried upload device, still nothing..

sorry "blur" can't show (working in office) wip app..

if use alertdialogbuilder can set style xml resource dialog. can use layoutinflator inflate custom view , call setview on builder
