CardView not showing shadow elevation

Question

I am working with cardviews but the problem is my CardView is not showing any elevation or shadow. I have already tried some of the methods suggested in stackoverflow answer

Answer 1

<android.support.v7.widget.CardView android:id="@+id/item_card"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:cardCornerRadius="2dp"
    app:cardUseCompatPadding="true"
    app:cardElevation="2dp"
    app:cardBackgroundColor="@color/md_white_1000"
    android:foreground="?android:attr/selectableItemBackground"
    android:clickable="true">

</android.support.v7.widget.CardView>

app:cardUseCompatPadding="true" is the main catch here

Answer 2

use this inside cardView to show shadow:

app:cardElevation="4dp"
app:cardMaxElevation="4dp"

Answer 3

Try this

    <android.support.v7.widget.CardView
            android:id="@+id/driverCurrentJobsCardView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="@dimen/dim_8"
            android:background="#ffffff"
            app:cardCornerRadius="4dp"
            card_view:cardElevation="4dp"/>

And make sure that you are using this dependency in gradle

compile 'com.android.support:cardview-v7:23.2.1'

Answer 4

Lot of good answers, but sometimes just one doesn't work for all. here's the one that worked for me after a lot of looking around,

Add this line to your CardView

app:cardUseCompatPadding="true"

So your cardview looks like this

  <androidx.cardview.widget.CardView
      android:id="@+id/cardView"
      android:layout_width="match_parent"
      app:cardUseCompatPadding="true"/>

Hope that works! Happy coding!

    android:layout_height="wrap_content"
