How to disabled ripple effect in TabRow or Tab in Jetpack Compose?

Time:07-28

I would like to use the TabRow, but when I click the background has a ripple effect that I do not want. Is there a way to change this? I have the Tab's selectedContectColor equal to the same background color of the page, but I still see a white ripple effect.

TabRow(
   modifier = Modifier.height(20.dp),
   selectedTabIndex = selectedIndex,
   indicator = { tabPositions ->
      TabRowDefaults.Indicator(
       modifier = Modifier.customTabIndicatorOffset(
         currentTabPosition = tabPositions[lazyListState.firstVisibleItemIndex]
         tabWidths[lazyListState.firstVisibleItemIndex]
       ),
         color = RED
      )
   },
   backgroundColor = BLACK
) {
    tabList.forEachIndexed{ index, tab ->
     val selected = (selectedIndex == index)
     Tab(
      modifier = Modifier
// Have tried different solutions here where there is a .clickable
// and the indication = null, and set interactionSource = remember{  
//MutableInteractionSource()}
      selected = selected,
      selectedContentColor = BLACK,
      onClick = { 
         animateScrollToItem(selectedIndex)
      },
      text = {
        Text("Text Code")
      }
     )

}

}

You can see in these docs that the selectedContentColor affects the ripple

CodePudding user response:

The ripple is implemented in a selectable modifier defined inside the Tab.

You can't disable it but you can change the appearance of the ripple that is based on a RippleTheme. You can define a custom RippleTheme and apply to your composable with the LocalRippleTheme.

CompositionLocalProvider(LocalRippleTheme provides NoRippleTheme) {
    //..TabRow()
}

private object NoRippleTheme : RippleTheme {
    @Composable
    override fun defaultColor() = Color.Unspecified

    @Composable
    override fun rippleAlpha(): RippleAlpha = RippleAlpha(0.0f,0.0f,0.0f,0.0f)
}

CodePudding user response:

The shimmer effect is handled by the indication property. Put it inside the clickable section.

You can create an extension function

inline fun Modifier.noRippleClickable(crossinline onClick: ()->Unit): Modifier = composed {
    clickable(indication = null,
        interactionSource = remember { MutableInteractionSource() }) {
        onClick()
    }
}

then simply replace Modifier.clickable {} with Modifier.noRippleClickable {}
