Android CardView With Rounded Corners Displays Grey Corners

I'm inflating a custom layout with CardView inside the layout. The rounded corners are displayed as expected but I also get grey background behind the corners. The code is simple,

Solution 1:

It is because of shadow, you need to give space to cardview to show full shadow. Add android:layout_margin="5dp" to CardView and you will see that the "grey" color is cut shadow.

Solution is adding app:cardUseCompatPadding="true" to CardView and it will give needed spacing.

Solution 2:

Try this...

Just set 0 value to app:cardElevation

.....
<android.support.v7.widget.CardView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:cardBackgroundColor="@android:color/white"
    app:cardCornerRadius="6dp"
    app:cardElevation="0dp">
.....

OR you can call cardView.setCardElevation(0) to disable shadow programmatically.

Solution 3:

Remove the parent RelativeLayout that is wrapping the CardView and you are good to go. Just like this:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
    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"
    app:cardBackgroundColor="@android:color/white"
    app:cardCornerRadius="6dp"
    app:cardElevation="5dp">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/transparent">

        <TextView
            android:id="@+id/tvProgress"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_centerVertical="true"
            android:layout_toLeftOf="@+id/ivIcon"
            android:layout_toStartOf="@+id/ivIcon"
            android:background="@android:color/transparent"
            android:padding="@dimen/elementPaddingSmall"
            android:text="Initial Discussion"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@android:color/black"/>

        <ImageView
            android:id="@+id/ivIcon"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_alignParentEnd="true"
            android:layout_alignParentRight="true"
            android:background="@color/lightBrown"
            android:scaleType="centerInside"
            android:src="@drawable/ic_checkmark_circle"/>
    </RelativeLayout>


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

Solution 4:

If someone faces the problem when the edges' color is darker than you set, it could happen if you set the color in #AARRGGBB format. To fix this issue, just set the color in the normal #RRGGBB format.

Solution 5:

Change app:cardUseCompatPadding="true" to card_view:cardUseCompatPadding="true"
