you need to use
app:cardUseCompatPadding="true"
this will do that job for you

Those are shadows of CardViews. It's normal, there is no problem.
So CardViews have their elevations that they drop shadows on the background.
You set radius for the CardViews. Then you can look the background through rounded corners. You see the shadows of CardViews dropping on the background.
app:cardCornerRadius="10dp"
If you don't want the rounded corners of the CardViews, I think you should just set the radius to 0.
app:cardCornerRadius="0"

add this, your problem with the shadow
app:cardElevation="#dimen/dp_0"

Android list row: image+text+image

I'm creating a list of items with a personalized layout for the rows. In each row I want to have two images of fixed size:
one must contact its left border with the left border of the row layout (red square).
the other one must contact its right border with the right border of the row layout (orange square)
In between these images I want to have some extra elements inside a layout (green area). Thus, the size of this layout should be match_parent, but without hiding neither of the previous two images.
How can I do this?
I'm trying to put three linear layouts, wrapping to width the first and the third, and matching_parent the green one, but the green is hidding the orange.
EDIT: This is what I have so far:

Button height custom list view

I'm trying to create a custom listview with 4 columns. Everything works fine, except for the height of each row, it's too big.
Here the result I have:
The problem comes from my button, because android take a weird height, that doesn't match the height of my image (I already check my image and it have the right proportion).
Here an example:
And I would like the "zone" of my image to just be the size of my image.
Here's my code:

If you have any idea on how I can change that, thank you
EDIT:
I found a solution, I needed to add this line of code to my ImageButton:
android:adjustViewBounds="true"

Needed changes:
wrap_content all the views.
android:layout_centerInParent="true" the txtAudioNote
Extra:
No need to the RelativeLayout at the bottom.

He has found a solution which he states in the EDIT:
android:adjustViewBounds="true"
But I want to add for those who want to do it programmatically.
//add in onCreate
view.setAdjustViewBounds(true);

Semi transparent background in CardView Does not work properly

I have problem with CardView background opacity. I want to make my background semi transparent, but I have a weir bug that happens all the time. The best explanation will be a screenshot from my program.
Scr from displayed layout
I want this Layout to be all in the same semi transparent color. Instead what appears is this semi transparent color with more transparent rectangle inside. I don't know how to remove this rectangle from my layout. Code:
<?xml version="1.0" encoding="utf-8"?>
<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"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_marginBottom="5dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardCornerRadius="15dp"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
app:cardBackgroundColor="#66000000">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="center">
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardCornerRadius="15dp">
<ImageView
android:id="#+id/flagImageView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:adjustViewBounds="true"
android:fontFamily="#font/changa_light"
android:scaleType="fitXY"
app:srcCompat="#mipmap/ic_launcher" />
</androidx.cardview.widget.CardView>
<TextView
android:id="#+id/flagTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="TEST"
android:textColor="#ffffff"
android:gravity="center"
android:fontFamily="#font/changa_light"/>
</LinearLayout>
</androidx.cardview.widget.CardView>
</LinearLayout>
</RelativeLayout>

SOLVED! I had to add app:cardElevation="0dp to the first CardView

Is this what you want?
<?xml version="1.0" encoding="utf-8"?>

app:cardBackgroundColor="#color/sisman2"
app:cardCornerRadius="20dp"
app:cardElevation="2dp">

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_alignParentBottom="true"
android:layout_marginBottom="8dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:ellipsize="end"
android:gravity="center"
android:singleLine="true"
android:text="HELLO"
android:textSize="24sp" />
</RelativeLayout>
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="248dp"
android:elevation="0dp"
app:cardCornerRadius="20dp"
app:cardElevation="0dp">
</androidx.cardview.widget.CardView>
</RelativeLayout>
</androidx.cardview.widget.CardView>

enclose the first cardView object in a frame layout, then give it elevation and keep it at the top (remember! elevation> = API 21)
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#color/transparentColor"
android:elevation="3dp"
android:stateListAnimator="#null">
<!-- into-->
</FrameLayout>

How remove unnecessary space between cards in RecyclerVIew?

I am using Recycler view + card view to show my content but there is unnecessary space between cards how to remove it.
I have tried with negative padding but didnt work. Any other solution to this? or there is any bug in my code.
my RecyclerView
<android.support.v7.widget.RecyclerView
android:layout_marginStart="4dp"
android:layout_marginEnd="4dp"
android:id="#+id/reyclerview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/darker_gray"

Cardview with dividers in it

I've seen those CardViews (I'm not sure they're even CardViews) with dividers used in a lot of apps, so I'm guessing there is an easy way to create them.
I wanted to ask how is it exactly done? are those even CardViews?
I couldn't find out more about them because I didn't know the name of the View exactly, so If someone could direct me to an example with code I'd be grateful.
Image example:

You can use this code this may help
<android.support.v7.widget.CardView
android:id="#+id/cardview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/margin_large"
android:layout_marginRight="#dimen/margin_large"
android:elevation="100dp"
card_view:cardBackgroundColor="#android:color/white"
card_view:cardCornerRadius="8dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center_vertical"
android:paddingLeft="25dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Conversations" />
</LinearLayout>
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#android:color/darker_gray" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="30dp"
android:paddingTop="20dp"
android:paddingBottom="10dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="game" />
...
</LinearLayout>
</LinearLayout>
</android.support.v7.widget.CardView>

The shown screenshot shows a normal CardView with views as divider in-between.
There is no DividerView or something similar if you searching for something like this. Just use a simple View with a height and a background.
I've something similar in a library of mine. I use this to create the divider:
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/stroke"/>
card_library.xml
<?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="wrap_content"

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"

android:maxLines="1"/>
<TextView

android:fontFamily="sans-serif-condensed"
android:textStyle="normal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="4dp"
android:layout_marginTop="4dp"
android:gravity="left|bottom"
android:maxLines="1"
android:textSize="12sp"/>
<TextView
android:id="#+id/librarycreator"
style="#style/CardTitle"
android:fontFamily="sans-serif-condensed"
android:textStyle="normal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="2dp"
android:gravity="right"
android:maxLines="2"
android:textSize="14sp"/>
</LinearLayout>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_marginTop="4dp"
android:background="#color/stroke"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:padding="4dp">
<TextView
android:id="#+id/description"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:maxLines="20">
</TextView>
</LinearLayout>
</LinearLayout>
It will then look like this:

Set app:cardElevation="0dp" then use a View - see below
<android.support.v7.widget.CardView
android:id="#+id/cv"
xmlns:android="http://schemas.android.com/apk/res/android"
app:cardElevation="0dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto">
<!-- Insert UI elements -->
<View
android:layout_width="fill_parent"
android:background="#android:color/darker_gray"
android:layout_height="2dp"/>
</android.support.v7.widget.CardView>
