DialogFragment gravity not showing dialog completely in corner

Question

I want dialog to appear completely in corner. I am setting gravity this way:

    Window win = dialog.getWindow();
    WindowManager.LayoutParams wmlp = win.getAttributes();
    wmlp.gravity = Gravity.TOP | Gravity.RIGHT;
    wmlp.horizontalMargin = 0;
    wmlp.verticalMargin = 0;

Margins don't affect anything here. Layout inspector also doesn't work on dialog so I can't really inspect what is setting margin/padding.

Can I show this dialog fragment completely in corner (without recreating custom overlay fragment over whole screen that acts as a dialog)?

That extra padding/margin may have something to do with the background drawable. Change the style of your dialog to set android:windowBackground and android:background to be transparent by doing something like this:

    <style name="TransparentDialog" parent="@style/Theme.AppCompat.Light.Dialog">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:background">@android:color/transparent</item>
    </style>

(I believe that android:windowBackground is important here, and you may not need to set android:background.)

Thanks goes to andrew who answered this question for helping to provide a solution.
