android rounded rectangle without background straight-edge rectangle

Question

I'm trying to make a dialog that appears as a rounded rectangle. I'm doing this by specifying the following shape xml as the background for the dialog layout.xml

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

    <solid    android:color="#FFFFFF"/>
    <corners  android:radius="40dp"/>
    <padding  android:left="10dp"
          android:right="10dp"
          android:top="10dp"
          android:bottom="10dp"/>
</shape>

The resulting dialog has rounded corners inside a black 90 degree rectangle. I want to know how I can get rid of the ninety degree rectangle that remains and show nothing but the rounded rectangle.

It seems like the rectangle template stays behind after I curve the corners:

Here's a link to a picture of the dialog my code's producing: http://img577.imageshack.us/img577/8292/photoon20110912at2032.jpg

Answer 1

Write your constructor as:

public CustomDialog(Context context, int theme) { super(context, theme); getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT)); }

Answer 2

Try this:

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:shape="rectangle">
<solid android:color="#B7B7B7"/>
<corners android:bottomLeftRadius="8dip"
    android:bottomRightRadius="8dip"
    android:topLeftRadius="8dip"
    android:topRightRadius="8dip"/>
</shape>
