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 Studio renders it in this way:
And this is what I want to have in my Dialog.
BUT:
On physical device and on emulator it looks different than in Android Studio:
My question is: how to place "Filter" title on the left, and make the location EditText matching the parent (in the working app)?

What everybody else said is correct, keeping your layout flat is good for both performance and for these situations where you want to quickly figure out why isn't the layout being laid out the way you wanted it ;)
Try this :
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

android:paddingHorizontal="15dp"
android:paddingVertical="10dp">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="start"
android:text="Filter"
app:layout_constraintBottom_toBottomOf="#id/bt_reset"
app:layout_constraintEnd_toStartOf="#id/bt_reset"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="#id/bt_reset" />
<com.google.android.material.button.MaterialButton
android:id="#+id/bt_reset"
style="#style/Widget.MaterialComponents.Button.OutlinedButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RESET FILTERS"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/tv_distance_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Distance range"
app:layout_constraintBottom_toBottomOf="#id/tv_distance_result"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="#id/tv_distance_result" />
<TextView
android:id="#+id/tv_distance_result"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:background="#ddd"
android:gravity="center"
android:paddingHorizontal="18dp"
android:paddingVertical="3dp"
android:text="0 km - 500km"
android:textColor="#333"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/bt_reset" />
<com.google.android.material.slider.RangeSlider
android:id="#+id/slider_distance"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:stepSize="1.0"
app:labelBehavior="gone"
app:layout_constraintTop_toBottomOf="#id/tv_distance_result" />
<TextView
android:id="#+id/tv_location_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Location"
app:layout_constraintTop_toBottomOf="#id/slider_distance" />
<EditText
android:id="#+id/et_location"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="test"
app:layout_constraintTop_toBottomOf="#id/tv_location_title" />
<Button
android:id="#+id/bt_cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_marginEnd="20dp"
android:backgroundTint="#ccc"
android:text="CANCEL"
android:textColor="#color/colorBlack"
app:layout_constraintEnd_toStartOf="#id/bt_save"
app:layout_constraintTop_toBottomOf="#id/et_location" />
<Button
android:id="#+id/bt_save"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_marginEnd="20dp"
android:text="save"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/et_location" />
</androidx.constraintlayout.widget.ConstraintLayout>

I changed inner ConstraintLayouts into LinearLayouts and used weights. I also used this trick to fill space between e.g. "Filter" title and "reset filters" button.
There was also an issue with ll_location LinearLayout - it didn't match the parent.
I replaced:
<LinearLayout
android:id="#+id/ll_location"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#id/ll_distance_ext"
android:orientation="vertical">
<!-- content -->
</LinearLayout>
into:
<LinearLayout
android:id="#+id/ll_location"
android:layout_width="0dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#id/ll_distance_ext"
android:orientation="vertical">
<!-- content -->
</LinearLayout>
And then it worked.
The reason why I don't want to use flat layout (why I use nested layouts) is that IMHO the flat layout makes the code more difficult to maintain.
When you have Views splited into groups you can easily replace them, no matter how many View there are in a group.

android - button is making the page background change to gray

Solved
I have a scroll view that has a Constraint Layout layout inside of it. I Have a button that is constraint to the bottom of the table but it seems to change the background below the table to gray. all other widgets that I have added do not have the same problem.
Screenshot of problem
I removed the inner code of the table as its not need

Try adding the following to either your ScrollView or ConstraintLayout:
android:background="#android:color/white"

Solved:
I solved my problem by putting the table inside of another Constraint Layout. I don't know if that is best practice but it works for now. Thank you #Shn_Android_Dev

Have you tryed to add .setBackgroundDrawable(null) to you button inside your class?
Example:
yourButton.setBackgroundDrawable(null);

How can I align Text next to an Image Button inside a vertical Scrollview

I want to align some text next to an Imagebutton inside of a vertically oriented Scrollview, but I am out of ideas.
This is an App for my Grandma, to help her understand her phone and the Symbols better.
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"

<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:paddingTop="20dp"
android:text="Button 1"
android:textSize="40dp"/>
</LinearLayout>

I can't manage to get the Text next to the Imagebutton

I would suggest to replace LinearLayout with RelativeLayout which is made just for this!
here are all of its attributes:

look for the LEFT_OF and RIGHT_OF attributes.

You Can use ConstraintLayout to make this layout super fast.
Here us an example layout:

It will look like this:
This will work for your Grandmas phone, but please notice that If you want to make a responsive layout using ConstraintLayout you will have to avoid using fixed sizes on your views and that's because different phones got different screen size so using fixed size value will not look the same on all devices.
You can use ConstraintLayout with guidelines and Chains to support different screen sizes.

To align some text next to an Imagebutton inside of a vertically oriented Scrollview. we can use linear layout with horizontal orientation
Like This
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageButton
android:id="#+id/Button1"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#drawable/srcbtn1" />
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:paddingTop="20dp"
android:text="Button 1"
android:textSize="40dp" />
</LinearLayout>
</LinearLayout>
</ScrollView>

Can I put a Button to bottom of a ConstraintLayout inside ScrollView?

I have a ScrollView contains a ConstraintLayout. Inside the ConstraintLayout, I put many views with an attribute layout_constraintTop_toBottomOf to make a relation between the view and the view top of it, and I used layout_marginTop to put spaces between the views.
In my design, I have a Button that should be in the bottom of the layout and it cannot happen with the layout_marginTop because it should have a relation with the bottom of the ConstraintLayout.
Here's my code:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="10dp"
android:paddingBottom="10dp">
<TextView
android:id="#+id/logo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_margin="120dp"
android:text="Logo"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<EditText

android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginLeft="28dp"
android:layout_marginTop="25dp"
android:layout_marginRight="28dp"
android:gravity="center"
android:hint="User name"
android:textColor="#bebebe"
android:textCursorDrawable="#null"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#id/logo" />
<EditText

android:layout_width="match_parent"

android:layout_marginTop="8dp"

android:paddingRight="28dp"
app:layout_constraintTop_toBottomOf="#id/pw_et">

android:textColor="#bebebe" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:text="Forget password?"
android:textColor="#a40000" />
</RelativeLayout>
<Button
android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginLeft="28dp"
android:layout_marginTop="17dp"
android:layout_marginRight="28dp"
android:text="Login"
android:textAllCaps="false"
android:textColor="#FFFFFF"
app:layout_constraintTop_toBottomOf="#id/save_pw" />
<Button
android:id="#+id/btn2"
android:layout_width="match_parent"
android:layout_height="50dp"
android:text="Sign up"
android:textAllCaps="false"
android:textColor="#FFFFFF"
app:layout_constraintTop_toBottomOf="#id/btn" />
</android.support.constraint.ConstraintLayout>
</ScrollView>

Replace ScrollView with NestedScrollView & also add android:fillViewport="true" like this
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
// rest of code
<Button
android:id="#+id/btn2"
android:layout_width="match_parent"
android:layout_height="50dp"
android:text="Sign up"
android:textAllCaps="false"
android:textColor="#FFFFFF"
app:layout_constraintVertical_bias="1"
app:layout_constraintTop_toBottomOf="#id/btn"
app:layout_constraintBottom_toBottomOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.core.widget.NestedScrollView>

Just set this property to your button:
app:layout_constraintBottom_toBottomOf="parent"
Then add this to your last view this property:
app:layout_constraintBottom_toTopOf="#+id/button"
Also, add to your last view:
android:layout_marginBottom="height_of_button"
However, if you are adding a lot of views it would be better to populate them inside a RecyclerView using an Adapter. Decide what you want to do. Also, tell me if I understood your question correctly, it was a bit confusing.

I found one solution to keep the button at the bottom, doesn't matter is your text is dynamic, read about app:layout_constraintVertical_bias https://developer.android.com/reference/androidx/constraintlayout/widget/ConstraintLayout#Bias
