How to reduce spaces between buttons in MDC-Android

I am learning to create UI in XML now, and I'm struggling with such a problem.
I create UI which looks like this: UI in Android Studio
And on the phone it looks like this: How it looks in reality (screenshot from a phone)
How to reduce these vertical spaces?
I want to get rid of this: These marked spaces
This is LinearLayout, and these are much bigger than I want them to be.
Here's my XML code for this UI:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Thanks very much for every helpful hint/answer!!!
I tried changing the weight, reducing DPI spaces, and setting the android:layout_marginTop/Bottom to 10 dpi, I thought it would stop it from increasing the spaces.

You need to reduce the layout_height property for the Linear Layout and for the Button .
And as an advice if you want to learn UI creation using XML just try playing around with the editor and test different things it will be much easier to learn & memorise this way.

The Warning
A scrolling widget such as a ScrollView should not contain any nested scrolling widgets since this has various usability issues

This should be works. There was a problem with the LinearLayout, the height was wrap_content. The first child of scrollview needs to have only match_parent for both width and height and that's it.

You need to use LinearLayout with android:orientation="horizontal" and play with android:layout_weight to allign your views.

To align views horizontally , you should use Linear Layout with horizontal orientation and assign weights to each child views.
Check this example which i have written using your layout -
<LinearLayout
android:id="#+id/layout_relative"
android:layout_width="fill_parent"
android:layout_height="90dp"
android:layout_marginTop="-5dp"
android:orientation="horizontal"
android:background="#007DD7">
<TextView
android:id="#+id/text1_login"
android:layout_width="0dp"
android:layout_height="40dp"
android:layout_gravity="center"
android:layout_marginLeft="45dp"
android:layout_marginTop="10dp"
android:background="#drawable/circle"
android:backgroundTint="#color/white"
android:gravity="center"
android:shadowRadius="10.0"
android:text="1"
android:layout_weight="1"
android:textColor="#android:color/holo_blue_dark"
android:textSize="18sp" />
<TextView
android:id="#+id/text2_login"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginTop="5dp"
android:layout_marginBottom="10dp"
android:layout_marginLeft="45dp"
android:paddingLeft="3dp"
android:paddingRight="3dp"
android:text="Login"
android:textColor="#color/white"
android:textSize="20sp" />
<TextView
android:id="#+id/text1_delivery"
android:layout_width="0dp"
android:layout_height="40dp"
android:layout_weight="1"
android:layout_gravity="center"
android:layout_marginLeft="170dp"
android:layout_marginTop="10dp"
android:background="#drawable/circle"
android:shadowRadius="10.0"
android:text="2"
android:gravity="center"
android:textColor="#android:color/holo_blue_dark"
android:textSize="18sp"
android:backgroundTint="#color/add_contact_selected"/>
</LinearLayout>

I saw all the answers people who has suggest to use LinearLayout.One thing you have to know very clearly.By using the Relative or Linear we can achieve all the layout design.
First you have to analyse which design will be good.Implementation may be depends on three things.
1.Easy designing
2.Layout performance
3.How much you know about attributes of layout.
My suggestion also Linear only for your implementation but some times multiple inner linear layout will cause performance issue and this also you should aware of it.
How we are developing the code is not important,how we are optimizing the code is very important.

Buttons distributed on top of an image, that stay in the same position no mater the screensize

I am making an app in which I am doing the following:
25 buttons (the red, 5x5) that are equally distributed throughout an image in the background and on the left side 5 buttons (brown) a bit closer to the edge.
I have looked at a few similar questions here, with relative layout, but the problem is that as soon as I adjust for one screen size, it doesn't fit with another any more...
Here is how it looks on my phone screen:
On other screensizes:
Here is my code:
(a bunch of code before that, but part about the image):
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:scaleType="fitXY"
android:src="#drawable/chord_box1" />
<LinearLayout
android:id="#+id/firstrow"
android:layout_width="match_parent"

I've made the first row and tried to make it fit, but I'm not sure how to make it fit on different screens. Is this the right way to do it, or should it maybe be done on the java code instead of the xml?

Change the layout_height of your top-level LinearLayout to "match_parent". Then it will cover the entire screen vertically.
<LinearLayout
android:id="#+id/firstrow"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignBottom="#+id/imageView1"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:gravity="center_horizontal"
android:orientation="vertical"
android:weightSum="10" >
You might need to re-adjust the weights to make it look exactly as it did before.

Textview.setText changes gravity of other objects

I have a textview inside a scrollview. Under the scrollview there is a tablelayout with a lot of buttons. When i through code change the text of the scrollview, like this.
textViewInput.setText("Hello");
It makes the buttons in the tablelayout change gravity so that the text in them is left aligned. Why is this happening? And i´ve made sure that textviewinput is´nt null.
Here´s the xml.

Because of
<TextView
android:id="#+id/textViewInput"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
...
Using wrap_content means that your TextView's width and height will change depending of it's content, which you modify when you call setText().
Try using fixed width and height, like this:
<TextView
android:id="#+id/textViewInput"
android:layout_width="match_parent"
android:layout_height="30dp"
...
