How can I get the images to scale with different screen sizes in Android Studio?


In my code my app runs fine, but I am running into issues when I am using a different screen size. The buttons line up correctly but the images do not scale at all.

This is my XML file

    </androidx.constraintlayout.widget.ConstraintLayout>
</ScrollView>

I have tried to set different constraints in the image view, I have tired

android:layout_width="wrap_content"
android:layout_height="150dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_height="150dp"

Just about any different configuration I have tried, I feel like I am missing something basic.


Solution

  • I have figured it out, I used CardView inside of the ScrollView, which kept the images the same no matter the screen size. I also used a LinerLayout for my buttons so they would stay at the bottom of the image!
