This answer is based on the layout found in your XML: https://pastebin.com/5AUKpCnn

 <ScrollView
        android:id="@+id/ScrollView01"
    ...
    <Button...
    <Button...
    <Button...
    ...
 </ScrollView>

It seems that you're trying to create a List by using a ScrollView and a lot of Buttons.
Creating a list like that loads all your images at once.

You should check out Android's ListView or RecyclerView for creating a list of clickable images. Those two can make things easier for you with their handling of List items so that they're not loaded all at the same time.
