android - Translucent dialog with margin -

i need create translucent dialog, 100dp margin top.
in code, add this:

 dialog dialog = new dialog(getactivity(), android.r.style.theme_translucent_notitlebar);   dialog.setcontentview(r.layout.transparent_progress_bar); 

and transparent_progress_bar:

<relativelayout         xmlns:android="http://schemas.android.com/apk/res/android"         android:layout_height="match_parent"         android:layout_width="match_parent"         android:layout_margintop="100dp"         >  <progressbar         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_centerinparent="true"         android:layout_gravity="center"         android:background="@android:color/transparent"         android:indeterminate="true"         android:indeterminatedrawable="@drawable/rotate_progress_bar"         android:indeterminateonly="true"         android:padding="@dimen/android_spacing_double"/>  </relativelayout> 

but doesn't work.
idea on how can modify theme or add margin this?

try this!!

in transparent_progress_bar.xml

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/relative_dialog_control"  android:layout_width="match_parent"  android:layout_height="match_parent"  android:background="@android:color/transparent"  android:layout_margintop="8dp" >  <view     android:id="@+id/view_close_top"     android:layout_width="match_parent"     android:layout_height="100dp" />  <relativelayout     android:id="@+id/relative_popup"     android:layout_width="match_parent"     android:layout_height="207dp"     android:layout_below="@+id/view_close_top"     android:layout_marginleft="9dp"     android:layout_marginright="9dp"     android:background="#ffffff"     android:padding="0dp">     <progressbar     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_centerinparent="true"     android:layout_gravity="center"     android:background="@android:color/transparent"     android:indeterminate="true"     android:indeterminatedrawable="@drawable/rotate_progress_bar"     android:indeterminateonly="true"     android:padding="@dimen/android_spacing_double"/> </relativelayout>  <view     android:id="@+id/view_close"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_below="@+id/relative_popup" /> </relativelayout> 

in res/value/style.xml add

 <style name="theme.transparent" parent="theme.appcompat.light.dialog">     <item name="android:windowistranslucent">false</item>     <item name="android:windowbackground">@android:color/transparent</item>     <item name="windownotitle">true</item> </style> 

this code when show dialog

 private void showpopupcontrol() {     final appcompatdialog dialog = new appcompatdialog(mainactivity.this, r.style.theme_transparent);       //dialog.getwindow().clearflags(windowmanager.layoutparams.flag_dim_behind);     dialog.setcontentview(r.layout.transparent_progress_bar);     viewgroup.layoutparams params = dialog.getwindow().getattributes();     params.width = viewgroup.layoutparams.match_parent;     dialog.getwindow().setattributes((android.view.windowmanager.layoutparams) params);      dialog.findviewbyid(r.id.relative_dialog_control).setvisibility(view.visible);     dialog.findviewbyid(r.id.view_close).setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view view) {             dialog.dismiss();         }     });     dialog.findviewbyid(r.id.view_close_top).setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view view) {             dialog.dismiss();         }     });      dialog.show(); }
