android 高度隐藏布局的所有视图

Answer 1

以下是我根据mãĴď评论所做的事情

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:background="@color/white">

    <androidx.cardview.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginStart="@dimen/margin_smallxx"
        android:layout_marginTop="@dimen/margin_normalxx"
        android:layout_marginEnd="@dimen/margin_smallxx"
        app:cardCornerRadius="10dp"
        app:cardElevation="20dp"
        android:outlineSpotShadowColor="@color/shadow_color"
        >

        <LinearLayout
            android:id="@+id/ll_main"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            ........
        </LinearLayout>
    </CardView>
</RelativeLayout>

这意味着我们将拥有卡片视图并将整个布局放入其中......
