android - 如何使布局可滚动？安卓

Question

您好，我正在尝试创建一个包含几个 ImageView 、一个按钮和一些文本的布局，但问题是该布局不可滚动。知道如何实现吗？非常感谢。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

   <ImageView
    android:id="@+id/imageView1"
    android:layout_width="match_parent"
    android:layout_height="204dp"
    android:scaleType="fitXY"
    android:src="@drawable/pic11elit" android:contentDescription="ss"/>

   <TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="whatever"
    android:textAppearance="?android:attr/textAppearanceLarge" />

   <TextView
    android:id="@+id/textView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

    android:textAppearance="?android:attr/textAppearanceMedium" />

  <TextView
    android:id="@+id/textView3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Reservation No :27210 10020"
    android:textAppearance="?android:attr/textAppearanceMedium" />
         <Button
    android:id="@+id/On_back"
    style="?android:attr/buttonStyleSmall"
    android:layout_width="73dp"
    android:layout_height="wrap_content"
    android:onClick="On_back"
    android:text="back" />
      </LinearLayout>

            android:src="@drawable/ic_launcher" />

        <TextView

            android:text="whatever"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <TextView

        <Button
