Answer 1

Please check sample module in Material-Calendar-View library. There are an examples where calendar background is same as day background and selected is marked with an image not the background.

If howeather you need remove margins between week rows when days are selected please modify calendar_view_picker_day.xml in such way:

Set <LinearLayout height same as child textView so android:layout_height="@dimen/day_label_size_events_disabled". Set <LinearLayout android:padding="0dp"

All modifications:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="@dimen/day_label_size_events_disabled"
    android:background="@drawable/day_picker_item_background"
    android:padding="0dp"
    android:orientation="vertical">
    <TextView ....
