Question

我有一个Layout.xml，它有可见和不可见/ Gone组件。我希望当 Gone Visibility组件可见时，布局应该可以滚动。

在下面的XML中，我希望第二个相对布局在其可见组件变为可见时可滚动 Layout.xml

</RelativeLayout>

请帮我实现。

Answer 1

在RelativeLayout上添加ScrollView。设置相对布局的位置属性（如边距）并将其高度更改为WRAP_CONTENT。

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:materialdesign="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/root_view"
    xmlns:roid="http://schemas.android.com/apk/res-auto"
    tools:context=".MainActivity"
    android:background="@color/backgroud_user">


    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="120dp"
        android:src="@drawable/comp_icon" />


   <ScrollView
         android:id="@+id/scrollView"
         android:width="match_parent"
         android:height="match_parent"
         android:layout_marginTop="20dp"
         android:layout_centerInParent="true"
         android:below="@+id/imageView1">

        <RelativeLayout
            android:id="@+id/LoginBox"
            android:layout_width="match_content"
            android:layout_height="wrap_content">

           ...
        </RelativeLayout>
    </ScrollView>
</RelativeLayout>

当处于可见模式时，您需要使用ScrollView滚动relativelayout。实际上，您应该在VISIBLE上使用GONE和ScrollView属性，并将其RelativeLayout作为其子视图

<RelativeLayout

    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:materialdesign="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/root_view"
    xmlns:roid="http://schemas.android.com/apk/res-auto"
    tools:context=".MainActivity"
    android:background="@color/backgroud_user">


    <ImageView

        android:layout_centerHorizontal="true"
        android:layout_marginTop="120dp"
        android:src="@drawable/comp_icon" />

  <ScrollView
    android:id="@+id/scrollView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/linearLayout"

    android:visibility="visible">
