Multiples imagesView with text in a ScrollView

I'm making a soundbox for me and my friends in android studio.
I've got a simple Scroll view, that I filled up with multiple constraintLayout that each contains 2 imageView with each of having a line of text under it.
The problem is that when I run the app, I only see the 2 first layouts, i've no idea what's going on and this is probably not the good way to do it.
What's the best solution here? Here is the xml code :

look like you are begginer.
<androidx.constraintlayout.widget.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="800dp"
android:background="#353535"

look like your problem
android:layout_height="800dp"
You set the fix height. Change it to match_parent.
<androidx.constraintlayout.widget.ConstraintLayout. And change root layout to FrameLayout or remove it.

android Seekbar width "match_parent" not working

I'm creating a seekbar in a dialog fragment, and for some reason, the seekbar width is not taking the whole available width. I guess it has something to do with the dialogfragment somehow.
here is my xml file:
<androidx.constraintlayout.widget.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">
<SeekBar
android:id="#+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="12dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
/>
<ImageButton
android:id="#+id/play_pause"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="12dp"
android:background="#drawable/play_icon"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#+id/seekBar" />
<TextView
android:id="#+id/player_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="12dp"
android:layout_marginEnd="8dp"
android:text="TextView"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="#+id/play_pause"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/seekBar" />
</androidx.constraintlayout.widget.ConstraintLayout>
you can see that the seekbar width is set to "match parent" but it's not working.
Although it's look good in the preview.

Use RelativeLayout as root layout for dialog XML file like this...
<RelativeLayout 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="wrap_content">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<SeekBar
android:id="#+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="12dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ImageButton
android:id="#+id/play_pause"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="12dp"
android:background="#drawable/play_icon"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#+id/seekBar" />
<TextView
android:id="#+id/player_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="12dp"
android:layout_marginEnd="8dp"
android:text="TextView"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="#+id/play_pause"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/seekBar" />
</androidx.constraintlayout.widget.ConstraintLayout>
</RelativeLayout>

How to write a viewPager inside a recyclerView full height

I have a RecyclerView with a ViewPager inside it, which in turn have another recyclerView. The recyclerView inside a ViewPager don't load whole items, but only one, and don't scroll to show the rest of the items
I have tried to set the layout_height of the two recycler view with wrap_content, and also nested it inside a nestedSCrollView, without success.
// First outside recyclerview
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
// cell item with viewPager
<com.google.android.material.tabs.TabLayout
android:id="#+id/tabLayout"
android:layout_width="match_parent"
android:layout_height="50dp" />
<androidx.viewpager.widget.ViewPager
android:id="#+id/viewPager"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
// recyclerView inside viewPager
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
I expect that the outside recyclerView fill the whole height of the items, instead the recycler view inside seams that don't load the whole items but the only one that is visible in the screen, without scroll.

Android Studio Linear Layout Design issue

I am having an issue with designing Android Studio Layout for App. In linear layout, I want to add first two layouts in the first column horizontally and then in the next column, I wish to add that three buttons in horizontally and finally in the last column want to add Listview. Any help would be highly appreciated. As currently, everything falls into one row.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<james.view.VideoView
android:id="#+id/remoteVideoView"
android:layout_width="120dp"
android:layout_height="90dp"
/>
<james.view.VideoView
android:id="#+id/localVideoView"
android:layout_width="120dp"
android:layout_height="90dp"
/>
<Button
android:id="#+id/startVideoButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start Call"
/>
<Button
android:id="#+id/stopVideoButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="End Call"
/>
<Button
android:id="#+id/sendmessage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="msg"
/>
<ListView
android:id="#+id/errorList"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</ListView>
</LinearLayout>
</android.support.constraint.ConstraintLayou
This is how I want my layout to be

If you don't understand Constraints. You can use regular LinearLayout.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="10dp"
tools:context=".MainActivity"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="90dp"
>
<james.view.VideoView
android:id="#+id/remoteVideoView"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
/>
<james.view.VideoView
android:id="#+id/localVideoView"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_marginLeft="10dp"
android:layout_weight="1"
/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
>
<Button
android:id="#+id/startVideoButton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Start Call"/>
<Button
android:id="#+id/stopVideoButton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="End Call"/>
<Button
android:id="#+id/sendmessage"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="msg"/>
</LinearLayout>
<ListView
android:id="#+id/errorList"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginTop="10dp"
android:layout_weight="1"
>
</ListView>
</LinearLayout>
Quite simple!

Solution:
This is exactly how you want, Just copy paste and your job is done:

Try it. Hope it helps.

This is a sample xml, similar to your image. Since your code uses constraintLayout I have created the xml using constraintLayout instead of linear layout. I have created this from the design screen and not from the text screen. This is the xml `
