Android soft keyboard hides edit text decorator

Layout MockI have a decorated (Framed) EditText which I use in my app. When the soft keyboard comes up it hides the part of the frame that is below the text view. For the frame functionality I use a LinearLayout which contains the EditText.
Is there a way to set the keyboard not to hide the bottom part of the frame(The containing Layout)?
Edit: I guess I am not explaining myself properly. The Linear layout containing the EditText is not the main fragment layout, it is contained in it and is used as a decorator for it. what I am basically trying to do is set a margin between the keyboard and the EditText so that the keyboard doesn't hide the surrounding LinearLayout which is again, not the main layout for the fragment.
In the mock, the problem is that the keyboard goes up all the way to the bottom of the EditText and covers the bottom part of the wrapper layout. I need the entire wrapper layout to be seen. Any Ideas.

You have to wrap your linear layout within ScrollView with the following property android:fillViewport="true" and in manifest write down the following line of code `android:windowSoftInputMode="adjustResize".

Set all your Activity view or layout in ScrollView.
Which will make your view scrollup when soft keyboard open and it don't hide your view.

Android: ScrollView vs NestedScrollView

What is the difference between ScrollView and NestedScrollView? Both of them, extend FrameLayout. I want to know in depth pros and cons of both of them.

NestedScrollView as the name suggests is used when there is a need for a scrolling view inside another scrolling view. Normally this would be difficult to accomplish since the system would be unable to decide which view to scroll.
This is where NestedScrollView comes in.

In addition to the nested scrolling NestedScrollView added one major functionality, which could even make it interesting outside of nested contexts: It has build in support for OnScrollChangeListener. Adding a OnScrollChangeListener to the original ScrollView below API 23 required subclassing ScrollView or messing around with the ViewTreeObserver of the ScrollView which often means even more work than subclassing. With NestedScrollView it can be done using the build-in setter.

Other than the advantages listed in the answers given, one more advantage of NestedScrollView over ScrollView is its compatibility with CoordinatorLayout. The ScrollView does not cooperate with the CoordinatorLayout. You have to use NestedScrollView to get "scroll off-screen" behaviour for the toolbar.
Toolbar will not collapse with Scrollview as child of CoordinatorLayout

NestedScrollView
NestedScrollView is just like ScrollView, but it supports acting as
both a nested scrolling parent and child on both new and old versions
of Android. Nested scrolling is enabled by default.
https://developer.android.com/reference/android/support/v4/widget/NestedScrollView.html
ScrollView
Layout container for a view hierarchy that can be scrolled by the
user, allowing it to be larger than the physical display. A
ScrollView is a FrameLayout, meaning you should place one child in it
containing the entire contents to scroll; this child may itself be a
layout manager with a complex hierarchy of objects
https://developer.android.com/reference/android/widget/ScrollView.html

NestedScrollView is just like ScrollView, but in NestedScrollView we can put other scrolling views as child of it, e.g. RecyclerView.
But if we put RecyclerView inside NestedScrollView, RecyclerView's smooth scrolling is disturbed. So to bring back smooth scrolling there's trick:
ViewCompat.setNestedScrollingEnabled(recyclerView, false);
put above line after setting adapter for recyclerView.

I think one Benefit of using Nested Scroll view is that the cooridinator layout
only listens for nested scroll events. So if for ex. you want the toolbar to scroll down when you scroll you content of activity, it will only scroll down when you are using nested scroll view in your layout. If you use a normal scroll view in your layout, the toolbar wont scroll when the user scrolls the content.

<androidx.core.widget.NestedScrollView android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
// your Layout xml code
</androidx.core.widget.NestedScrollView>

Preventing Scrollable layout when using webview/mapview

I am stuck in one situation...I have my parent layout as a scrollable layout. Inside this layout, I have a webview and a tablelayout. Some data are inflated in this scrollable layout.
My question is, my vertical scrollable functionality seems to be disabled since my scrollable layout already have the functionality. I hardly can scroll up and down inside the webview. And same situation for Mapview. I can only zoom in and zoom out using horizontal gesture. I wonder if there is any way to disable the scroll functionality only when I zoom in/out, scroll up/down in mapview/webview. Thank you so much.

Scrollable layout overlaps views

Can I set scrollable layout only when soft keyboard overlaps some views? I can detect if keyboard is visible, but can I detect if some views are overlapped and only then set it to scrollable?

No need to deal with ScrollView. You can use android:windowSoftInputMode="adjustPan" in the Activity tag of your Manifest to automatically adjust without using scrollview.

ExpandableListView affecting the size of Scrollview when collapsing and expanding

Let me try to explain what I want to achieve. Currently, I have a ScrollView as the main view for my layout and a linearLayout within that to place all of my content into.
In my LinearLayout, I have a bunch of textviews and a gallery, which extends out of the screen, so the user can scroll to see everything. It works.
Now, I want to add an expandableListView to the bottom of all that content, which is still in the linearLayout. The problem is when you expand the list view groups it doesn't affect the ScrollView. I had envisaged that when you expand a group it would make the linearLayout bigger, which in turn makes the scrollview bigger.
Is what I'm thinking achievable?
EDIT:
Ok I think the situation is that listViews are normally placed in a layout by themselves and have scrollviews already enabled. You just set it to fill_parent and it works fine. However, in my case, I'll need the expandableListView to display all content without scrolling, because my ScrollView will deal with that. I don't even think it possible?

It's difficult to answert without seeing your layout xml, but I think that if you set the android:layout_height of the linear layout and expandableListView to wrap_content, the first scrollView must scroll the whole view.

have you tried putting your expandable list into another linear layout and than put it in the scroll views default linear layout?
