I am using google cardView support library for my card functionality. It works well for kitkat and version up but however the background of card is set to black and padding/margins are not applied on device 4.1.2.
<android.support.v7.widget.CardView
android:id="@+id/all_goals_card_view"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_marginRight="20dp"
android:layout_marginLeft="20dp"
android:layout_gravity="center"
android:layout_marginTop="20dp"
android:layout_marginBottom="20dp"
android:padding="10dp"
app:cardCornerRadius="4dp"
card_view:cardPreventCornerOverlap="false"
card_view:cardBackgroundColor="@android:color/white"
>
</android.support.v7.widget.CardView>
Okay, I just stumbled across the same issue and I found some devices to have some "special" very-light light-theming defaults cough samsung cough I will answer this slightly old queston.
The thing here is that you are most likely using the wrong context
to inflate you layout. I think you are using the application-context
to do so. Application-Context does not apply the theme you defined.
This (inflating with the application-context) is legal, but inflation will be done with the default theme for the system on which you are running, not what’s defined in your application.*
For example if you do:
LayoutInflater.from(context).inflate(R.layout.menu_rental_list_item, parent, false);
The context
here should be an Activity-
or Fragment
Context
- NOT the application-context.
Please double check that.
*) Ah, you want to read more about contexts? Please continue reading here.
don't use "@android:color/white"
card_view:cardBackgroundColor="#fff"
This will solve the issue:
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#fff"
card_view:cardBackgroundColor="#fff"
android:layout_margin="2dp">
Notice these lines:
xmlns:card_view="http://schemas.android.com/apk/res-auto"
and
card_view:cardBackgroundColor="#fff"
