layout_weight doesn't take effect

Question

I'm trying to split the vertical space between views evenly using layout_weight but from some reason it doesn't work. I followed this answer and still the views's spaces aren't effected by that. What am I doing wrong?

<LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical">

                <Space
                    android:layout_width="1dp"
                    android:layout_height="0dp"
                    android:layout_weight="1" >
                </Space>

                <android.support.design.widget.TextInputLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content">

                    <AutoCompleteTextView
                        android:background="@drawable/rounded_corners_white"
                        android:id="@+id/email"
                        android:paddingEnd="16dp"
                        android:paddingStart="16dp"
                        android:layout_marginRight="16dp"
                        android:layout_marginLeft="16dp"
                        android:layout_height="40dp"
                        android:layout_width="match_parent"
                        android:inputType="textEmailAddress"
                        android:maxLines="1"
                        android:singleLine="true" />

                </android.support.design.widget.TextInputLayout>

                <Space
                    android:layout_width="1dp"
                    android:layout_height="0dp"
                    android:layout_weight="1" >
                </Space>

                <android.support.design.widget.TextInputLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content">

                <EditText

                <Button

Please explain further what you're trying to accomplish, and what exactly isn't working as expected. From what I can tell from your description, that layout will do what you want. — Mike M., Jul 06 '16 at 13:53
That's what that layout will do. You have one space at the top, a space between each `View`, and they will all be equal height. To check, you can temporarily change the ``s to ``s, set their `layout_width`s to `match_parent`, and give them `background` colors. Btw, I think you mean vertical space. — Mike M., Jul 06 '16 at 14:16
I have tried your code in xml file and don't see any problems. The items seem to be spaced equally. What needs to be solved? — Marat, Jul 06 '16 at 14:26
So, your specific problem is that it's not taking up the entire screen vertically? — Daniel Nugent, Jul 06 '16 at 15:05

Just add below line to your linearlayout:

android:weightSum="4"
