[asker517]

happened in Latest version

just create a list as balloon content ,then add android:background="?attr/selectableItemBackground" on list item for click background status

however, when i click first item or last item ..radius limit ripple background

that not expected .. only wanna radius on balloon not for content

Hi, could you build and test using the demo project? The CustomListBalloonFactory creates the same Balloon that you said.

@skydoves that my codes below:

class CustomListBalloonFactory : Balloon.Factory() {

  override fun create(context: Context, lifecycle: LifecycleOwner?): Balloon {
    return Balloon.Builder(context)
      .setLayout(R.layout.common_layout_custom_list)
      .setWidth(BalloonSizeSpec.WRAP)
      .setHeight(BalloonSizeSpec.WRAP)
      .setPaddingTop(4)
      .setPaddingBottom(4)
      .setArrowOrientation(ArrowOrientation.TOP)
      .setArrowPositionRules(ArrowPositionRules.ALIGN_ANCHOR)
      .setArrowPosition(0.5f)
      .setArrowSize(6)
      .setCornerRadius(4f)
      .setMarginRight(8)
      .setBackgroundColorResource(android.R.color.white)
      .setBalloonAnimation(BalloonAnimation.FADE)
      .setDismissWhenShowAgain(true)
      .setDismissWhenTouchOutside(true)
      .setDismissWhenOverlayClicked(true)
      .setLifecycleOwner(lifecycle)
      .build()
  }
}

almost the same as you demo, just remove some padding setting that not need in my case

[skydoves]

Hmm, that's weird. Or how about adding the below style to your theme?

<item name="colorControlHighlight">@color/colorPrimary</item>

[asker517]

@skydoves ...it's worked ..!!

[skydoves]

Great! :)

[asker517]

@skydoves Oh..I'm sorry ...i just revert my code...actually..it's not work ....when i add <item name="colorControlHighlight">@color/colorPrimary</item>

[asker517]

if i called

setCornerRadius(0f)

..both balloon and it's content has no radius

[skydoves]

Hi, could you please describe your specific issue again? I think setCornerRadius(0f) works fine in the demo project.

it's right, setCornerRadius(0f) is no problem, i mean only i add setCornerRadius(0f) can make my content has no radius ..for example,if i setCornerRadius(2f) ..both balloon shape and its content has radius,but actually i only wanna balloon shape has round corners with radius..

[asker517]

just like this...some way to avoid item1 background without radius?

[asker517]

@skydoves seems the issue is RadiusLayout's background radius presented always smaller than yourcanvas.clipPath(path)'s path radius presented...even though..they are same value.. if set RadiusLayout.clipToOutline=true will be nice result that i expected..but api level 21 above limited

i don't know wether it is a issue or just you wanna design like this..but it's really a wired phenomena if user set background to balloon content .

looking forward your better solution.

It looks like when radius value is set on RadiusLayout it expects it to be @Dp value, but in fact it is already a @Px value. Which applies dp->px coefficient again and corners of RadiusLayout have radius different from background gradient.

@skydoves em...

/** corner radius for the clipping corners. */
  @Px private var _radius: Float = 0f
  var radius: Float
    @Px get() = _radius
    set(@Dp value) {
      _radius = value.dp
      invalidate()
    }

you are right...issue is here...set(@Dp...)..actually when called radius = builder.cornerRadius...builder.cornerRadius was a px value already..

Hi @asker517 @Azazel, sorry for the late reply. This issue has been fixed on the new release 1.3.8-SNAPSHOT and this will be included in the next stable. Thanks for your report. :)

[skydoves]

A new stable 1.3.8 has been released!
