I have some problem with a layout. I am putting a cardView inside a NestedScrollView and totally inside a CoordinatorLayout. And, it adds a lot of padding at the bottom. Can some body please explain as to why is this happening. I know that the cardView uses extra padding in below-L devices to show rounded corners and shadows, but does it need this much of padding and that too only at the bottom.

  • Paste your layouts, please – archived Feb 13 '16 at 15:31
  • try adding (padding="0dp") to the layout(s) and see if that helps – Tasos Feb 13 '16 at 16:30
  • This is possibly a duplicate of [CardView has extra margin in each edge on Pre-Lollipop](http://stackoverflow.com/questions/29068430/cardview-has-extra-margin-in-each-edge-on-pre-lollipop), if so - checkout the ["hacky" solution](http://stackoverflow.com/a/29148964/5908572) – archived Feb 14 '16 at 17:48

Used to have the same problem and I fixed it by wrapping the CardView inside a FrameLayout

<android.support.v4.widget.NestedScrollView>
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <android.support.v7.widget.CardView
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <RelativeLayout
                android:layout_margin="@dimen/activity_horizontal_margin"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">
                <TextView
                    android:id="@+id/info_event_details_date"
                    android:text="12th July"
                    android:layout_alignParentRight="true"
                    android:textSize="@dimen/date_text_size"
                    android:textColor="#90000000"
                    android:textStyle="bold"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    />
                <TextView
                    android:id="@+id/info_event_details_title"
                    android:layout_toLeftOf="@id/info_event_details_date"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="Attention! Students placed in Amazon."
                    android:textColor="#ab000000"
                    android:textSize="@dimen/title_text_size"/>
                <View
                    android:id="@+id/info_event_details_divider_title_content"
                    android:layout_below="@id/info_event_details_title"
                    style="@style/Divider"
                    android:layout_marginTop="@dimen/activity_vertical_margin"
                    android:layout_marginBottom="@dimen/activity_vertical_margin"
                    />
                <TextView
                    android:id="@+id/info_event_details_desc"
                    android:layout_below="@id/info_event_details_divider_title_content"
                    android:textSize="@dimen/content_text_size"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" />
            </RelativeLayout>
        </android.support.v7.widget.CardView>
    </FrameLayout>
</android.support.v4.widget.NestedScrollView>
