i need help.
i have a RecyclerView containing different View such as Cardviews. Those CardViews contains a ListView
the cardViews height is wrap content and the listviews hight is also wrap content.
the listView in the first card contains three items
the second card only one and the last card has a subitem.
how can i archive that the cards grow if their content change or if the expandableListView opens
i'm sorry for my bad engish

I have two linear layout inside constrainLayout,
The bottom linear layout includes buttons and its height is wrap_content and must be wrap, because sometimes I keep only 1 button and sometimes 2 buttons.
I would like to set height of the top linearLayout to max but without covering the 2nd layout.
So I decided to set match_parent to the first, but after that it covers the 2nd layout.
I can't use weight/weightsum

Since you are using ConstraintLayout, you can set the height of the first LinearLayout to 0dp. The ConstraintLayout interprets it as "match constraints".
The next step would be to properly define the constraints of the first LinearLayout (which you did).
You can read more about ConstraintLayout here.

To do this you have to use a combination of linearlayout as parent and attribute layoutWeight ,If you use a constant value for layoutWeight for both top layout and button's container , then this will lead to some problem on different screen height devices , instead this solution make you able to set your buttons height as big as enough by setting its container's height to wrapContent and give all top area for the layout content .
You can also make the top linearLayout scrollable to get the best experience possible :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/this_layout_will_fil_all_space_except_the_bottom_layout_space"
android:layout_width="match_parent"
android:layout_height="0dp"
android:orientation="vertical"
android:background="#000000"
android:layout_weight="1">
</LinearLayout>
<LinearLayout
android:id="#+id/button_layout_at_bottom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center_horizontal"
android:padding="10dp">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button1"
android:layout_marginEnd="50dp"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button2"
android:visibility="visible" />
</LinearLayout>
</LinearLayout>
For Buttons , you can set its width to wrapContent and add gravity attribute to its parent as above , in this way even if one buttons was gone , the other will fit perfectly in the center of the container .
Enjoy !
The main advantage of using ConstraintLayout is to avoid using any other nested ViewGroups, The more you add more hierarchy in layout, the less performance you'll have. You can check documentation for more.
So for performance wise it's better to add widgets/views directly within the ConstraintLayout.
So, here I removed the bottom LinearLayout, and kept only the buttons directly within the ConstraintLayout, you can do the same for the top LinearLayout, you can just add any underlying views directly to the 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.

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.

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 am trying to add PieChart from MPAndroidChart and seekBar under it.
But still no luck, chart is visible, but other content is noT visible, despite it visible when I open design tab during xml configuration.
I already have tried to set a barrier and with groups with weights but still.
Could please anyone give any advice how to properly align chart to be able to see other widgets on view.
Here is my xml example:
<?xml version="1.0" encoding="utf-8"?>

ANSWER
The first and correct version of answer from Ashish Kudale is: Use LinearLayout with weight:
<LinearLayout
android:id="#+id/chartContent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.github.mikephil.charting.charts.PieChart
android:id="#+id/pieChart"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="4"/>
<android.support.v7.widget.AppCompatSeekBar
android:id="#+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
</LinearLayout>
Use LinearLayout Insted of ConstraintLayout.
Try this.
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/linearLayout3"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.github.mikephil.charting.charts.PieChart
android:id="#+id/pieChart"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<SeekBar
android:id="#+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="text" />
</LinearLayout>
</LinearLayout>
What it does is places all items in the screen and remaining place is occupied by item which has android:layout_weight="1"
Right now I'm using a simple RecyclerView that's supposed to be showing up under a TextView. However when I populate the RecyclerView with more items, it gets cut off and wont scroll down. What I remember from RecyclerViews is that every implementation I've done basically worked out of the box when it comes to scrolling.
