</LinearLayout>

我尝试使用 ScrollView 但我在 LogCat 中遇到了这个错误

ScrollView can host only one direct child

所以我正在寻找另一个解决方案，可能是通过 Activity 中的代码或其他方式。

你应该把内容放在ScrollView里面，像这样

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.twaa9l.chates.MyProfile">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <RelativeLayout
                android:layout_weight="1.5"   
                android:layout_width="match_parent"
                android:layout_height="0dp">
                ...
            </RelativeLayout>
            ...
        </LinearLayout>
    </ScrollView>
</LinearLayout>
