When using the android:foreground="?android:attr/selectableItemBackground" property on a CardView, the ripple originates from the center of the CardView, instead of from the touch origin.

XML:

<android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto&quot; android:layout_width="match_parent" android:layout_height="wrap_content" android:clickable="true" android:foreground="?android:attr/selectableItemBackground">

Fixed in master branch. Affects all non-background drawables.

Will there be an OTA to push out this update and others like it?

Android Build == "LPV79"

Device(s) == Nexus 5/Hammerhead (Device), Nexus 7 2013 (Emulator), Nexus 5 (Emulator).

Reproduce with the following code in XML layout:

<android.support.v7.widget.CardView
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:id="@+id/card_view"
    android:foreground="?android:attr/selectableItemBackground"        android:layout_width="480dp"
    android:layout_height="wrap_content"
    android:onClick="Method"
    android:focusable="true"
    card_view:cardCornerRadius="4dp"
    android:elevation="2dp"></android.support.v7.widget.CardView>

Although happens when in other/less parent view too.

Frequency: 100% of the time.

Expected output: Animate from the location the finger touch upon input.

Current output: Animates from the center of the card_view.

logcat output: null. (upon pressing the (card_view)button Logcat outputs nothing - No Filters set in Logcat).

Screen capture of the issue: Not available as is animated effect.

I apologise for not providing a bug report.

@10 For some reason, I see this issue occurring on Android Lollipop, version 5.0, build LRX21T (Nexus 4) .

Will the fix be available for the next version/build ? Or was it supposed to be fixed even on this version?

Is there maybe a workaround for this issue?

I've also noticed it happens with all views, and not just card views. It also occurs for the phone app, on the part of the "speed dial", with the contacts' photos.

The fix is not included into 5.0.2 (Nexus 7 2012).

BTW, when using this method of the foreground selection, on pre-Lollipop versions, the selection goes outside of the cardView content, so it looks bad.

For now, it's still better to use simple FrameLayout with your own drawables...

Anyone got a workaround for this? Am using cardview with recyclerview and can't get the ripple to originate from touch hotspot, but apps like gmail, pushbullet can somehow achieve this.

Not even the rippledrawable seems to work.

Also, I couldn't find any official sample that implements ripples.

@16 you could put a FrameLayout with foreground property set for it as the one you wish to use.

^+1 though now the ripple 'leaks' onto the cardview shadows

@18 True. You can mimic the card background and use a normal FrameLayout though.

On my app, this bug appears only in one activity. I can't understand where is the difference between those two recyclerview/cardview...

android:foreground is wrong if the CardView is being used in a ListView or GridView (possibly Recyclerview too). Use android:drawSelectorOnTop="true" in the ListView or GridView.

@21 So how would you define the selector for the CardView ?
