Question

在android 4.0.4中，我的卡片视图出现在底部附近的虚假灰色下划线。我似乎无法摆脱它，我尝试弄乱边缘和填充等但没有运气。

继承我的XML：

<android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:id="@+id/button_daily_calls"
    android:layout_width="@dimen/menu_button_width"
    android:layout_height="@dimen/menu_button_height"
    android:layout_marginTop="@dimen/top_menu_button_topmargin"
    android:layout_marginLeft="@dimen/menu_button_leftmargin"
    android:layout_marginRight="0dp"
    android:elevation="@dimen/menu_button_elevation"
    card_view:cardCornerRadius="@dimen/menu_button_radius"
    card_view:cardUseCompatPadding="true"
    android:paddingBottom="0dp">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:padding="@dimen/menu_button_padding"
        android:text="DAILY CALLS"
        android:textSize="@dimen/menu_button_textsize"
        android:textColor="@color/colorPrimaryDark"/>
</android.support.v7.widget.CardView>

Answer 1

你试过替换

吗？

xmlns:card_view="http://schemas.android.com/apk/res-auto"
card_view:cardUseCompatPadding="true"

带

xmlns:card_view="http://schemas.android.com/apk/res-auto"
card_view:cardPreventCornerOverlap="false"

这样可以防止Corners重叠，从而在图片和CardView之间没有间隙。

因此它适用于所有不同的Android版本，您应该执行以下操作：

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        cardView.setPreventCornerOverlap(true);
    } else {
        cardView.setPreventCornerOverlap(false);
    }

这应该会有所帮助，因为在使用Android 4.0.4时，图像周围总会有填充。当您设置cardView.setPreventCornerOverlap(false);时，它不应该再这样做了。
