Sticky view with vertical scrolling using constraint layout or any other way in android

The red portion is wrap content and can be expanded, depends on how much data it contains. The green part/view always sticks between red and white. The screen is vertically scrollable.
THE attached XML code having scrollview and layout weight but it divides the screen into two parts from the middle, which is not as per the requirement.
Please suggest how to achieve this.

You can use constraint layout inside a nestedScrollView like this :
<?xml version="1.0" encoding="utf-8"?>
<androidx.core.widget.NestedScrollView 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">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/redPortion"
android:layout_width="match_parent"
android:layout_height="wrap_content" //Red Portion
android:orientation="vertical"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<com.google.android.material.card.MaterialCardView
android:id="#+id/green_sticky_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#+id/redPortion" //Green Sticky View
app:layout_constraintBottom_toBottomOf="#+id/redPortion"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
/>
<LinearLayout
android:id="#+id/whitePortion"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" //White Portion
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/redPortion"
/>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.core.widget.NestedScrollView>
Use any layout you want for your red, white and green views.
I hope This helps.

Add small button on the upper right of imageview

Currently i have this layout:

where i need to add additional 'X' button on the upper left side of the imageview

You can use FrameLayout. Your icon must have android:layout_gravity attribute.
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/myImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dip"
android:src="#mipmap/ic_launcher"/>
<ImageView
android:id="#+id/imgX"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_gravity="top|left" //This line
android:src="#mipmap/ic_launcher_round" />
</FrameLayout>
Hope it helps.

Try this:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="80dp"
android:layout_height="108dp"
android:background="#ffffff">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="8dp"
android:background="#e6e6e6" />
<ImageView
android:layout_width="16dp"
android:layout_height="16dp"
android:src="#drawable/ic_cancel_black" />
Output:

Unable to scroll linear layout inside a horizontal scrollview in android

I am adding few image views inside a horizontal LinearLayout which is again inside a HorizontalScrollView. But the linear layout is not scrolling. Below is my code. Can someone guide me where exactly my xml formation is going wrong?
<?xml version="1.0" encoding="utf-8"?>
<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="15dp"
android:layout_marginBottom="2dp"
android:fillViewport="true"
android:orientation="horizontal">
<LinearLayout
android:id="#+id/lyt_items"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:id="#+id/iv_icon1"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:contentDescription="#string/app_name"
android:layout_marginRight="1dp"
android:src="#drawable/default_ic" />
<ImageView
android:id="#+id/iv_icon2"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:contentDescription="#string/app_name"

android:layout_height="match_parent"
android:contentDescription="#string/app_name"
android:layout_marginRight="1dp"
android:src="#drawable/default_ic" />
</LinearLayout>
</HorizontalScrollView>

I would suggest use Constraint Layout As Parent and Inside it Use Nested Scroll View With Linear Layout
Here is a sample code, modify according to your need.
<?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="suraj.iitgandhinagar.Login">
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
tools:layout_editor_absoluteX="72dp"
tools:layout_editor_absoluteY="0dp"
tools:ignore="MissingConstraints">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
tools:layout_editor_absoluteX="0dp"
tools:layout_editor_absoluteY="36dp">
<ImageView
android:id="#+id/imageView4"
android:layout_width="272dp"
android:layout_height="237dp"
android:layout_gravity="center"
android:layout_marginTop="40dp"
android:src="#drawable/unnamed"
tools:layout_editor_absoluteX="0dp"
tools:layout_editor_absoluteY="59dp" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.constraint.ConstraintLayout>

Take a look at this situation. if you use the linear layout as match_parent then don't get the layout width. Use wrap_content. If its don't work then set the fixed size for your image.
<HorizontalScrollView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="15dp"
android:layout_marginBottom="2dp"
android:fillViewport="true"
android:orientation="horizontal"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:id="#+id/lyt_items"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/iv_icon1"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:contentDescription="#string/app_name"
android:layout_marginRight="1dp"
android:src="#mipmap/ic_launcher" />
<ImageView
android:id="#+id/iv_icon2"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:contentDescription="#string/app_name"
android:layout_marginRight="1dp"
android:src="#mipmap/ic_launcher" />
<ImageView
android:id="#+id/iv_icon3"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:contentDescription="#string/app_name"
android:layout_marginRight="1dp"
android:src="#mipmap/ic_launcher" />
</LinearLayout>
</HorizontalScrollView>

how can make my xml images fit for all devices?

I'm new to designing of android, So I want my main screen images fit to all devices i want this MainScreen page fit to be in all devices. It has 3 images I have given weight but nothing seems to work if I test it on tab. Its not looking the way I want, here is the image
here is my XML .I know I should not give dp for height but how to make it look like that without giving sizes.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Hope this will help you

See following xml solution to get what you need.
You always can change relative width and height of the each view element by playing layout_weight parameter. Its like give width/height in percents :
<?xml version="1.0" encoding="utf-8"?>
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#android:drawable/btn_default"
android:scaleType="fitXY"
android:layout_weight="70"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_weight="30">
<ImageView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:src="#android:drawable/btn_default"
android:scaleType="fitXY"
android:layout_weight="1"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:src="#android:drawable/btn_default"
android:scaleType="fitXY"
android:layout_weight="1"/>
</LinearLayout>

How do I get an imageView and textview to both fill the layout when setting bitmap programmatically?

What I want is for qrcodetext to fit and display all the text in qrcode_layout and have qrimageView to fill the rest of qrcode_layout? But my layout below has the entire qrimageView cover qrcode_layout. I tried a bunch of other variations but without success.
Here is what it looks like.
Here is what I want it to look like.
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent">

android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/qrimageView"
android:layout_gravity="center_horizontal"
android:layout_marginTop="8dp" />
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/qrcodetext"
android:gravity="center"
android:layout_gravity="center_horizontal"
android:layout_marginTop="4dp" />
</LinearLayout>

android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
</RelativeLayout>

Use following code. Align your textview to bottom and then align your Qrcode Image above text:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/qrcodetext"
android:gravity="center"
android:layout_alignParentBottom="true"
android:layout_marginTop="4dp" />
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/qrimageView"
android:layout_gravity="center_horizontal"
android:layout_above="#id/qrcodetext"
android:layout_alignParentTop="true"
android:layout_marginTop="8dp" />
</RelativeLayout>
