how to remove layout background

Question

I am trying to remove background from popup dialog, but it's showing white color behind the cardview

background = @null is not working

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/lnrMstr"
android:orientation="vertical"
android:background="#0D000000">

    <android.support.v7.widget.CardView
        android:id="@+id/card_view_main"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:cardCornerRadius="@dimen/_5sdp"
        app:cardElevation="@dimen/_5sdp"
        app:cardUseCompatPadding="true"
        android:layout_margin="@dimen/_2sdp"
        android:layout_gravity="center_horizontal">

 </android.support.v7.widget.CardView>

</LinearLayout>

`#0D000000` should be either `#00000000`, or `@android:color/transparent`. Also, use `dp` to set the CardView margins. — Susmit Agrawal, Aug 20 '18 at 12:48
If you have a white bg color on `#0D000000` then this bg color might be related to a parent of the `LinearLayout`, since `#000000` is black and not white. — Abbas, Aug 20 '18 at 12:57

you don't need to remove that color from background just set dialog window background as transparent.

add in code:

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
