    android:layout_height="wrap_content"
    android:id="@+id/scrollView"
    android:layout_alignParentStart="true"
    android:layout_marginTop="56dp" />

    <ImageView android:id="@+id/imageView"
     android:layout_column="1"
     android:background="@mipmap/lpussy"
     android:ContentDescription="@string/desc"
     tools:ignore="HardcodedText"
     android:layout_width="200dp"
     android:layout_height="230dp" />`

 ......Then at the end

<ScrollView>

Answer 1

ScrollView只能容纳一个直子。ViewGoup之类的LinearLayout，RelativeLayout可以充当ScrollView的直子。然后，将其他子项添加到ViewGoup中。这是演示

<ScrollView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/scrollView"
    android:layout_alignParentStart="true"
    android:layout_marginTop="56dp" >
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <ImageView android:id="@+id/imageView"
            android:layout_column="1"
            android:background="@mipmap/lpussy"
            android:ContentDescription="@string/desc"
            tools:ignore="HardcodedText"
            android:layout_width="200dp"
            android:layout_height="230dp" />`

        ......Then at the end
    </LinearLayout>
</ScrollView>

在开头和结尾添加ScrollView时，content_main.xml文件崩溃
