More AndroidView fun!

I want to get my AndroidView to ripple on click or long click

AndroidView(
    factory = { context ->
      FrameLayout((context).apply {
     setOnClickListener {  }

this doesn't give me a ripple

[Colton Idle]

Old wisdom tells me I should set background of my view to

"?selectableItemBackground"

which you can apparently do programatically via

val outValue = TypedValue()
context.theme.resolveAttribute(
    android.R.attr.selectableItemBackground,
    outValue,
    true
)
setBackgroundResource(outValue.resourceId)

still no dice though... 😭

Not at my desk so can't check, but could you move the click listener to the AndroidView via its Modifier? I seem to recall you may need a solid background for the ripple, but not 100% sure

[Colton Idle]

let me try that. didn't know that AndroidView had a modifier param 🤦

[Colton Idle]

nope. no dice. 🤯

Try constructing RippleDrawable as a background maybe? Ripples are weeeeird

I have a ripple with this

AndroidView(
    modifier = Modifier.clickable {  },
    factory = { context ->
        FrameLayout((context)).apply {
        }
    }
)

this also works

AndroidView(
    factory = { context ->
        FrameLayout((context)).apply {
            val typedValue = TypedValue()
            context.theme.resolveAttribute(
                R.attr.selectableItemBackground,
                typedValue,
                true
            )
            setBackgroundResource(typedValue.resourceId)
            setOnClickListener {  }
        }
    }
)

in the 2nd case, the ripple is less noticeable though

[Colton Idle]

Weird. Maybe there's something else in my setup that's the culprit. I'll try to work backwards from here. Thanks all!

Random but compose ripples don't show on Android 14 b3.

thanks, im specifically not running this on my beta device for this reason. 😅
