ScrollView does not scroll up properly when inside BottomSheet

I created a ScrollView inside a BottomSheet and yes, it scrolls down properly but when it stops and I try to scroll up, the BottomSheet instead collapses. But when I scroll down first before scrolling up, it actually scrolls up properly. I don't want my users to feel the need to scroll down first before actually scrolling up because this can cause user frustration.
Here is my xml code:

Button not visible when keyboard is shown

I am trying to implement a functionality where the button below EditText moves up when the keyboard is shown, this is a login fragment and I would like to have this functionality similiar to what Instagram has. Right now, when keyboard is pressed, the EditText moves up but the button is hidden. I am attaching the xml below for the same.

Use ConstraintLayout to position the button to the bottom of the screen and then add.
<activity
android:name=".activity"
android:windowSoftInputMode="adjustResize"
android:exported="false" />
...in the activity that would host that Fragment's layout.
Note
The button should be layout in this manner:
<androidx.constraintlayout.widget.ConstraintLayout>
<Button
android:id="#+id/finish"
android:layout_width="match_parent"
android:layout_height="wrap_content"
... />
</androidx.constraintlayout.widget.ConstraintLayout>
... but right now in your code, I can see the button inside a LinearLayout. Change the layout to make the button be positioned at the bottom of a ConstraintLayout and make that ConstraintLayout the parent of that button. The ConstraintLayout should also fill the whole screen.
Edit:
When you use windowSoftInputMode="adjustResize the system positions the element at the bottom of the screen on top of the keyboard and makes your layout shrink in size. So you need to attach a ScrollView to make your layout scrollable.
Like this:
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
...>
// Position this scrollView to fill the entire screen
<ScrollView
android:layout_width="0dp"
android:layout_height="0dp"
...>
// This scroll view layout would contain all your other layout views
</ScrollView>
<Button
android:id="#+id/finish"
android:layout_width="match_parent"
android:layout_height="wrap_content"
... />
</androidx.constraintlayout.widget.ConstraintLayout>
Working principle
The button should not be a child view of the ScrollView, it should be a child view of the root view, which is a ConstraintLayout that fills the screen, then the button is positioned to the bottom of the root view. The bottom of the ScrollView should be positioned to the top of the Button. That way, the child views of the ScrollView is scrollable and the button stays on top of the keyboard.

Go to your AndroidMenifest File, Inside you <activity> tag put android:windowSoftInputMode = "adjustpan" it would handle the view after showing up keyboard. if adjustpan doesn't work, there are more property, use one respect to your need.
example:
<activity
android:name=".YourActivityName"
android:windowSoftInputMode="adjustPan"
android:exported="false" />

Android button outside of a text view

What is the best way to achieve the following UI where I want a button to appear "outside" and above a TextView?
Here's what I want to do (expected), the code I've written for it, and how it appears in my emulator (actual).
Expected: the "x" button is outside of the text view
My Layout:
(also, note: I'm inflating the bottom_sheet_layout in a class that extends com.google.android.material.bottomsheet.BottomSheetDialogFragment)
<androidx.constraintlayout.widget.ConstraintLayout

add this adjustResize to the activity tag in your manifest , then your view will shrink if keyboard opens.
<activity
android:name=".Activities.MyActivity"
android:windowSoftInputMode="adjustResize" ----->this tag
/>
and for your scroll it might help but let me know if it didnt , and post some screenshots of how your view looks.

android scrollview not scrolling down after keyboard opens

I have a textview that is inside of a scrollview, it scrolls fine untill the soft keyboard is opened.
When the keyboard is opened it act like it scrolled up again with the height of the keyboard.
What I have tried
I tried this in the manifest, but yielded the exact same results
android:windowSoftInputMode="adjustResize"
Then this:
android:windowSoftInputMode="adjustPan"
That seemed to work, but the problem was that it was moving the whole screen up and taking the header out of view.
I also tried adding the following in the linear layout
android:focusable="true"
android:focusableInTouchMode="true"
That only caused the app not to focus on the input field (EditText) and the keyboard didn't open automatically, but when you clicked on the input field it would just act the same as before.
This is the XML file code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/lightGray"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/bottom_layout"
android:layout_marginTop="10dip" >
<LinearLayout
android:id="#+id/msg_list_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</ScrollView>
<RelativeLayout
android:id="#+id/bottom_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#android:color/background_light">
<Button
android:id="#+id/send_btn"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="#string/txt_send" />
<EditText
android:id="#+id/msg_edit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/send_btn"
android:layout_toLeftOf="#+id/send_btn"
android:inputType="text" >
</EditText>
</RelativeLayout>
Any suggestions?

I had same problem and the solutions is this:
My activity was in fullscreen mode and scroll does not work in this mode this is a bug and we send a report to google.
Just look at your activity in manifest if there is a fullscreen mode just remove it.

I got this problem and it is a headache.
the soloution is instead of drawing an XML layout from the top of the screen, you need to draw it from the bottom of the screen.
look at these examples :

the second XML file main_contents2 drew from top and android just put the EditText from top of the keyboard.BUT the main_contents drawn from the bottom of the screen. so when the soft keyboard comes up the layout resizes.

Try changing the layout_height of scrollview to wrap_content.

All you need to do is
android:isScrollContainer="true"
