我的布局有些问题。我将一个cardView放在NestedScrollView中,完全放在CoordinatorLayout中。并且,它在底部添加了大量填充。有人可以解释为什么会发生这种情况。我知道cardView在下面的L设备中使用了额外的填充来显示圆角和阴影,但它是否需要这么多的填充,而且只需要在底部。

用于遇到同样的问题,我通过将CardView
包裹在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>
