 直接使用ScrollView加个ImageView就可以了，非常简单

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    tools:context=".MainActivity">
<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="none"
    android:fillViewport="true">
        <ImageView
            android:id="@+id/iv"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scaleType="fitStart"
            android:src="@drawable/a"
            tools:ignore="MissingConstraints"
            android:adjustViewBounds="true">
        </ImageView>

</ScrollView>
</LinearLayout>
