How to add a scroll view in an Android app

I want to add scroll in my XML without editing the following code. Is there any way of adding it in the following XML? I tried by adding Scroll view and then linear view but it makes the view cut. Is there any way of making it better, I have searched other repository but I didn't find a solution.

Please try the following code, I just changed the scroll view to be match_parent for width and height and the linear layout to be match_parent for width& wrap_content for height.
Please note that this view won't scroll till you run it on a small screen device.
and please change the images as you need.

While I didn't found properties or function but when I change this:
CategoricalAxis horizontalAxis = new CategoricalAxis();
chartView.setHorizontalAxis(horizontalAxis);
LinearAxis verticalAxis = new LinearAxis();
chartView.setVerticalAxis(verticalAxis);
to this:
CategoricalAxis horizontalAxis = new CategoricalAxis();
chartView.setVerticalAxis(horizontalAxis);
LinearAxis verticalAxis = new LinearAxis();
chartView.setHorizontalAxis(verticalAxis);
My problem has been solved.

This is part of the output:
My question is how to align my Confirm and Cancel buttons (last part of the xml) to buttom of the screen?
I saw examples of how it can be done using relative layout, but my xml is quite big and i dont want to have to change it to relative layout as it will mean lots of work.
Thanks.

And here your using lot of LinearLayouts but personally i recommend you to try out relativelayout

Use the android:layout_gravity="bottom" attribute on the buttons as well as their containing LinearLayout.

Add
android:layout_weight="1"
in second last LinearLayout and
android:layout_weight="0"
in last LinearLayout. Hope this work for you.

It's actually very easy to use the RelativeLayout, because you can be very smart about it. For example, wrap it around everything, so that your current parent linear layout will be the first child, end put the linear layout with the buttons at outside of the current parent with the parameter alignParentBottom
