How can I change the position of the hint in an editText?

I want to align my second hint(email) to match the position of the first one(nickname), and I can't seem to do it.
Please check my layout from this link
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/textInputLayout"
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"

I made a few modifications to your code to end up with this. The trick it to constrain the end of the first firstName1 to the start of lastName1 and do the opposite for lastName1 and distribute the margins between them at the boundary.

Set hint on top of TextInputEditText in TextInputLayout

How to set hint of TextInputEditText on top of view.
I have the following edit text that user will type description of the product, but hint is on center of view.
Here is the XML code.
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/interestDescriptionView"
style="#style/TextInputLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:maxLines="5"
app:layout_constraintBottom_toTopOf="#+id/tagsView"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/titleView"
app:layout_constraintVertical_chainStyle="packed">
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/interestDescriptionEditTextView"
android:layout_width="match_parent"
android:layout_height="200dp"
android:textAlignment="viewStart"
android:hint="Descrição *"
android:layout_centerHorizontal="true"
android:gravity="start|top"
android:imeOptions="actionDone"
android:inputType="textMultiLine|textCapSentences"
android:importantForAutofill="no" />
</com.google.android.material.textfield.TextInputLayout>

You can set android:minLines to 2 or greater .. this will make it work
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/interestDescriptionView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:hint="Descrição *"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/textview"
app:layout_constraintVertical_chainStyle="packed">
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/interestDescriptionEditTextView"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_centerHorizontal="true"
android:gravity="top"
android:imeOptions="actionDone"
android:importantForAutofill="no"
android:inputType="textMultiLine|textCapSentences"
android:maxLines="5"
android:minLines="2"
android:textAlignment="viewStart" />
</com.google.android.material.textfield.TextInputLayout>

NestedScrollView not scrolling to the bottom

This layout is part of my learning process. So please don't judge the use of textview for displaying data.
The problem is i am not able to scroll the entire data in the bottom textview. Always 2 sets of data is left behind.
If i have 8 sets,the scrollview will show up to 6 sets. If i have 4 set it will show 2 sets and wont scroll at all. What's the problem with my scrollview?

This is how my layout looks.
Thanks in advance.

Edit ConstraintLayout root layout_height (match_parent instead of wrap_content)
For NestedScrollView :
Replace layout_widthand layout_height values by 0dpfor applying constraints.
Add a bottom constraint with app:layout_constraintBottom_toBottomOf="parent"
