I am trying to make a Dialog that looks like this
Here, the elements in orange rectangles are fixed header and footer sections of the Dialog. The elements inside blue rectangle are placed dynamically depending on what content is to be shown.
Here it the XML for this.
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/header_section"
android:layout_width="match_parent"
android:layout_height="wrap_content"

app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<!-- some views -->

android:id="#+id/body_section"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintTop_toBottomOf="#id/header_section"
app:layout_constraintBottom_toTopOf="#id/footer_section"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent">

<LinearLayout

app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent">
<!-- some views -->
</LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.cardview.widget.CardView>
It works fine when I place other views inside the blue area, but when a RecyclerView is placed inside it and items are dynamically added to it, it grows in size and overlaps the text in header section and pushes the footer section to bottom. How can I make the RecyclerView cover only the blue area?
Use height 0dp in body section so it will fit between header and footer

I use ScrollView to tackle this,

android:layout_height="wrap_content"
android:layout_marginTop="16dp"

android:paddingVertical="8dp"
/>
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
The main attributes are these 3
app:layout_constraintHeight_min="100dp"
app:layout_constraintHeight_max="250dp"
app:layout_constrainedHeight="true"

I am new to constraint layout and I am trying to add my button below recyclerview, but I am not able to do that in constraint layout.
How I can achieve this functionality in constraint layout.
I am also share image for better understanding.
Try this sample code:
<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:layout_height="match_parent">
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/button"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
The important point is that the ListView's height must be 0 and app:layout_constraintBottom_toTopOf="#+id/button" and app:layout_constraintTop_toTopOf="parent" .
Try something like this:
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/constraintLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/listview"
android:layout_width="wrap_content"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/myButton"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/myButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
what I want to achive
A scrollView which expends the free vertical space only if needed and a button which is appended on bottom of that scrollView but not hidden by the footer when the amount of the items in the scroll view increases.
whats the problem
scrollView android:layout_height = wrap content:
the button stays at the bottom of the scrollView. But then, if the ScrollView extends, the button is hidden behind the footer.
scrollView android:layout_height = 0dp:
the button stays visible while the scrollView extends the screen height. But then the button position is fixed because the scrollView is not resizing according to the amount of items.
But I didn't find a way to meet both criterias.
question
how do I set the constraints of this Layout to get the expected behaviour (see first image below)?

Just keep in mind that your approach above won't be recycling any views in the RecyclerView adapter, so if the data is big then performance might become a concern.
Screenshots from Android Studio:
I have a view constrained to bottom of the parent. I also have text fields on top. how ever when the keyboard shows up, it will push bottom views up which will cover my text fields.
I have everything inside a scroll view, keyboard should cover the bottom view and I should be able to scroll to bottom to reach the bottom view.
Here is a simple example. I manually increased the height to reproduce the problem easier. I actually have more views, this is just for demonstration.
note that fillViewPort is also enabled.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView 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_height="match_parent"
android:fillViewport="true">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">

android:id="#+id/edit_text_1"
android:layout_width="0dp"
android:layout_height="180dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />
<EditText
android:id="#+id/edit_text_2"
android:layout_width="0dp"
android:layout_height="180dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#id/edit_text_1" />
<View
android:id="#+id/bottom_view"

</androidx.constraintlayout.widget.ConstraintLayout>
</ScrollView>
You just simply need to put the ScrollView inside a ConstraintLayout
like this:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:layout_width="0dp"
android:layout_height="180dp"
android:inputType="textPersonName"
android:ems="10"
android:id="#+id/edit_text_1"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
<EditText
android:layout_width="0dp"
android:layout_height="180dp"
android:inputType="textPersonName"
android:ems="10"
android:id="#+id/edit_text_2"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#+id/edit_text_1"/>
<View
android:layout_width="0dp"
android:layout_height="160dp"
android:id="#+id/bottom_view"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#+id/edit_text_2"/>
</androidx.constraintlayout.widget.ConstraintLayout>
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
I have a Fragment composed of three subfragments :
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white">
<fragment
android:id="#+id/header"
class="xxx.xxx.xxx.HeaderFragment"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<fragment
android:id="#+id/content"
class="xxx.xxx.xxx.ContentFragment"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/footer"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#id/header" />
<fragment
android:id="#+id/footer"
class="xxx.xxx.xxx.FooterFragment"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:maxHeight="64dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"/>
</android.support.constraint.ConstraintLayout>
This way, the ContentFragment fills the space between HeaderFragment and FooterFragment, as shown in the picture below :
green = header
blue = content
red = footer
Now I would like to add two views to the ContentFragment layout (one TextView and one ScrollView), so that those views take the whole blue space available.
Here is the layout for ContentFragment :
<?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"
android:background="#color/lightBlue">
<TextView
android:background="#color/white"
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="32dp"
app:layout_constraintEnd_toEndOf="#id/right"
app:layout_constraintStart_toStartOf="#id/left"
app:layout_constraintTop_toTopOf="parent"/>
<ScrollView
android:id="#+id/scrollView"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginTop="16dp"
android:background="#color/white"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="#id/right"
app:layout_constraintStart_toStartOf="#id/left"
app:layout_constraintTop_toBottomOf="#+id/textView">
<TextView
android:id="#+id/veryLongTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</ScrollView>
<android.support.constraint.Guideline
android:id="#+id/left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.05" />
<android.support.constraint.Guideline
android:id="#+id/right"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.95" />
</android.support.constraint.ConstraintLayout>
This is what I get instead :
Can someone explain why there is some space between the bottom of the scrollview and the bottom of the blue part ? It is not what I have defined in the constraints, which is rendered like this in Android Studio :
I am still unsure why this is happening. My guess is that Android cannot compute the right height for the ContentFragment at runtime, because the problem disappears if I define the fragments height using Guidelines as shown below :
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white">
<fragment
android:id="#+id/header"
class="xxx.xxx.xxx.HeaderFragment"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintBottom_toTopOf="#+id/topLimit"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<fragment
android:id="#+id/content"
class="xxx.xxx.xxx.ContentFragment"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/bottomLimit"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#id/topLimit" />
<fragment
android:id="#+id/footer"
class="xxx.xxx.xxx.FooterFragment"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintTop_toBottomOf="#id/bottomLimit"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"/>
<android.support.constraint.Guideline
android:id="#+id/topLimit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:layout_constraintGuide_percent="0.15" />
<android.support.constraint.Guideline
android:id="#+id/bottomLimit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:layout_constraintGuide_percent="0.85" />
</android.support.constraint.ConstraintLayout>
Which is rendered like this :
I need to achieve the following view
I tried using constraint layout:
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintBottom_toTopOf="#id/segmentedButton">
</FrameLayout>
<Buttons
android:id="#+id/segmentedButton"
android:layout_width="match_parent"
android:layout_height="50dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent">
</Buttons>
</android.support.constraint.ConstraintLayout>
It works well when there are many items, but when there are just 2-3, it shows them in the middle.
Also, I tried using LinearLayout but no luck.
you can use RelativeLayouttoo to get your desired results. By using the below code you can show the items on top if they are 2 or 3 left.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:id="#+id/frameLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/segmentedButton"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true" />
<Button
android:id="#+id/segmentedButton"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</RelativeLayout>
try with linear layout, weight property should push the button to align at the end of parent
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
>
<FrameLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:layout_weight="1"
>
</FrameLayout>
<Buttons
android:id="#+id/segmentedButton"
android:layout_width="wrap_content"
android:layout_height="50dp"
>
</Buttons>
</LinearLayout>
I supposed here that Buttons stand for a custom Button you made
Just add Top Constraint to your FrameLayout, should fix your issue.
Your final layout will be like this:
