android - Remove alert dialog border With Custom Theme

Question

In my application i am using alert dialog with rounded rectangle theme.But it have alertdialog rectangle and my theme.My problem is how to replace alert dialog border like dialog.I want to show this set item with own theme only.

I want output this manner instead of the above theme:

Main Activity:

AlertDialog.Builder alertSeverity = new AlertDialog.Builder(
           getActivity(), R.style.Theme_CustomDialog);
     alertSeverity.setTitle("Severity Status");
CharSequence[] severityStatus = { "Low-Severity",
           "Middle-Severity", "High-Severity" };
     alertSeverity.setItems(severityStatus,
           new DialogInterface.OnClickListener() {        

              @Override
              public void onClick(DialogInterface dialog, int which) {
                }
                 });

My Theme:

<style name="Theme.CustomDialog" parent="android:style/Theme.Dialog">
    <item name="android:windowBackground">@drawable/shapedialogtheme</item>
<item name="android:windowFrame">@null</item>

</style>

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"  >

<solid android:color="#565656" />

<stroke
    android:width="5dp"
    android:color="#ffff8080" />

<corners android:radius="30dp" />

<padding
    android:bottom="10dp"
    android:left="10dp"
    android:right="10dp"
    android:top="10dp" />
<size 
    android:width="150dp"

Use Dialog instead of AlertDialog.

Create your custom layout which you want to show in dialog and setContent in dialog. Apply this theme android.R.style.Theme_Translucent_NoTitleBar in dialog it will hide border.

Here is sample code.

Dialog dialog = new Dialog(activity.this, android.R.style.Theme_Translucent_NoTitleBar);

// your layout file
dialog.setContentView(R.layout.dialog);

// for hide title 
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

//for set title
dialog.setTitle("Custom Dialog");


dialog.show();

just tried this in AlertDialog.

AlertDialog.Builder alertSeverity = new AlertDialog.Builder(
           getActivity(), android.R.style.Theme_Translucent_NoTitleBar);
