Scaling an ImageView when the soft keyboard opens

I'm creating a tabbed activity. As long as the first tab is selected, the soft keyboard should be visible. I achieved that by adding this line to my manifest file in the activity tag:
android:windowSoftInputMode="stateVisible|adjustResize"
As the keyboard opens, the space for the layout shrinks. The most space is occupated by an ImageView. I want it to shrink with the layout size to allow the other 2 views (which should remain the same size) to fit on the screen. However, although the soft input mode is set to adjustResize, the ImageView keeps its size after the keyboard opens. Here's a comparison of the current layout and the one I want to achieve (the ImageView is the red rectangle):

How to force the ImageView to resize according to the screen size to make all of the views fit on the screen?
[EDIT]: My attempt to create a ConstraintLayout, which didn't solve the problem (the ImageView still keeps its original size):
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context=".DataInputFragment">
<ImageView
android:id="#+id/img"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitStart"
android:src="#drawable/image"
android:adjustViewBounds="true"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/input_label"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/input_label_text"
app:layout_constraintTop_toBottomOf="#id/img"/>
<namespace.InputEditText
android:id="#+id/input_edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#id/input_label">
<requestFocus />
</namespace.InputEditText>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/submit"
app:layout_constraintTop_toBottomOf="#id/input_edit_text"/>
</android.support.constraint.ConstraintLayout>

I've created an Android Project from scratch on Android Studio 4.0, using the "Tabbed Activity" template and uploaded it to GitHub.
I've had no issues with the resize taking place when the activity is resized.
What Did I change?
In the manifest.xml I added android:windowSoftInputMode="adjustResize"
I modified the default layout for the fragment in the tab to include an ImageView (called imageToShrink) and an EditText (called editLayout).
I left the existing TextView untouched, except that since it's at the top, I made it the HEAD of the vertical Chain, and gave it a 0.0 BIAS to be aligned at the top, rather at the center.
When you tap on the cyan EditText at the bottom, the keyboard pops (I made it number only so it's even taller) and you can see how the image is re-drawn after its new size is recomputed.
This is how it looks when it opens: (beautiful color palette!)
And this is how it looks when I tap the "edit field" to pop the keyboard:

your ImageView should not have wrap_content attributes, because it will always have constant size and wont be able to resize automatically. I would suggest using ConstraintLayout and use app:layout_constraintDimensionRatio. Other option is use LinearLayout weight (not recommending).
Ant third option is to detect when keyboard is visible, when not with ViewTreeObserver.OnGlobalLayoutListener and do stuff programmaticaly.
Try this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".DataInputFragment">
<ImageView
android:id="#+id/img"
android:layout_width="match_parent"
android:layout_height="0dp"
android:adjustViewBounds="true"
android:scaleType="fitStart"
android:src="#drawable/image"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintDimensionRatio="3:1"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.0" />
<TextView
android:id="#+id/input_label"

<requestFocus />
</EditText>

How to Control Visibility of items in a Linear Layout in my App?

I have a Vertical linear layout with 2 item. One is a is a customview which is extended from a framelayout and the 2nd one is a textview with a drawable as background. The visibility have to be controlled dynamically from gone to visible.
The issue is that when i change the visibility of the item from gone to visible the order is not coming as i intended. The the second item is below the customview. I want it to come as the 2nd item, below the customview
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:textureview="http://schemas.android.com/apk/res-auto">
<LinearLayout
android:id="#+id/comment_holder"
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<com.custom_views.CircularFrameLayout
android:id="#+id/comment_holder_circular_layout"
android:layout_gravity="center_horizontal"

<com.custom_views.PlaybackTextureView
android:visibility="gone"
android:id="#+id/playback_texture_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
textureview:isAuthorMode="true"/>
</com.custom_views.CircularFrameLayout>
<LinearLayout
android:visibility="gone"
android:id="#+id/c_holder"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="8dp"
android:paddingBottom="16dp"
android:paddingStart="4dp"
android:paddingEnd="4dp"
android:background="#drawable/chat_bubble_top_arrow_orange"
android:orientation="vertical">
<TextView
android:id="#+id/video_comment_user_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:textColor="#color/black_50"
android:fontFamily="sans-serif" />
</LinearLayout>
</LinearLayout>
</FrameLayout>
NOTE: I tried adding weight to the custom layout as 1. But it still didnt help.

Scroll up Relative Layout when scrolling up listview

I'm creating an application. and the user information is shown in a relative layout. Under the relative layout is a listview with items the user created. I want if you scroll down in the List View that the Relative Layout scroll up and eventually disappeared, and the list view is stretched over the whole screen.
Like you have in de facebook app.

</RelativeLayout>
<ListView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="8"></ListView>
</LinearLayout>
</merge>
Thanks in advance!

You have 2 options here:
1) You should put your entire layout inside NestedScrollView and change ListView into RecyclerView.
2) Or you can set your layout with profile picture as header view for listview.
For this you need to put your layout with profile in other xml layout file, then inflate it in code and use listview.addHeaderView(view v)

Android: Swipe to refresh gets stuck on a recycler view with view pager

Here is my XML code
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/flipper">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/refreshLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/headerLayout"
android:background="#color/background_color"
android:visibility="visible">
<android.support.v7.widget.RecyclerView
android:id="#+id/list_appointment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</android.support.v4.widget.SwipeRefreshLayout>
<RelativeLayout
android:id="#+id/emptyView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:visibility="gone">
<ImageView
android:id="#+id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:src="#drawable/ic_event_note"
android:textAppearance="?android:textAppearanceMedium" />
</RelativeLayout>
</FrameLayout>
The RecyclerViews adapter supports two types of views one is CardView and another is ViewPager.
When I swipe to refresh, the circular refresh icon freezes on top of the ViewPager.onrefresh method is called after I tap the refresh icon again.Is there any fix to this issue?

While scrolling RecyclerView CoordinatorLayout is shown

I have implemented an activity with two slides, the slides content is a fragment with RecyclerView that loads data from my server and creates a GridLayout with images (like in image gallery).
I have added the behavior of scrolling so when you scroll you don't see the toolbar.
My problem is that when the activity starts with the fragment the toolbar is half hidden and when i continue to scroll down and the toolbar is completely hidden the CoordinatorLayout from under is exposed so i get this thing:
as you can see the light green is the CoordinatorLayout and the red is the ViewPager and what i want to achieve is that when you scroll more you will only see the red background and never the green one.
My activity_main.xml

How can I make the toolbar to hide when I am scrolling but still see the RecyclerView content on my entire screen?
Thanks...
