我正在开发我的第一个完全由Compose设计的应用程序。
我需要使用Text() compose组件垂直集中文本。在传统的Android开发实践中，我通过alignment属性完成了此操作。Text() compose也有alignment属性，但目前它的容量有限（仅允许Alignment.Horizontal()），尽管我注意到Text()中不同的对齐值，当在web中进行研究时。Column()的类似情况-它还具有对齐属性.wrapContentSize()，且还具有对这里可以使用值的限制，尽管在web中的快速研究表明它也可以接收CenterVertically。
你是如何实现这种视觉效果的呢？完整的代码如下

@ExperimentalUnitApi
@Composable
fun TripBookingContent(state: PassengerTripUiState.TripBookUiState) {
    Log.d(App.TAG, "[screen] TripBookingContent")
    val baselineGrid = dimensionResource(id = R.dimen.baseline_grid)
    val mainPadding = dimensionResource(id = R.dimen.main_margin_compact)
    var componentSpace = dimensionResource(id = R.dimen.component_space)
    Column(
        modifier = Modifier
            .wrapContentHeight()
            .fillMaxWidth()
            .padding(
                paddingValues = PaddingValues(
                    horizontal = mainPadding,
                    vertical = baselineGrid
                )
            )
    ) {
        TripViewItem(
            data = state.trip,
            {},
            modifier = Modifier.padding(vertical = baselineGrid)
        )
        Text(
            text = stringResource(id = R.string.booking_screen_driver),
            color = colorResource(id = R.color.white),
            style = TextStyle(textIndent = TextIndent(firstLine = TextUnit(16F, TextUnitType.Sp))),
            modifier = Modifier
                .height(componentSpace)
                .padding(start = baselineGrid)
                .fillMaxWidth()
                .background(color = colorResource(id = R.color.design_default_color_secondary_variant))
        )
        Log.d(App.TAG, "[state] state.driver - ${state}")
        Log.d(App.TAG, "[state] state.driver.toDriver() - ${state.driver}")
        DriverCardContent(data = state.driver)

        Text(
            text = stringResource(id = R.string.booking_screen_msg),
            color = colorResource(id = R.color.white),
            style = TextStyle(textIndent = TextIndent(firstLine = TextUnit(16F, TextUnitType.Sp))),
            textAlign = TextAlign.Center,
            modifier = Modifier
//                .height(componentSpace)
                .height(32.dp)
                .padding(start = baselineGrid)
                .fillMaxWidth()
                .background(color = colorResource(id = R.color.colorPrimaryDark))
        )
        /**
         * Disable book button at current (alfa version), for more details
         * */
        Button(
            onClick = { /* no op */ },
            modifier = Modifier
                .alpha(0F)
                .fillMaxWidth()
                .padding(baselineGrid)
                .height(dimensionResource(id = R.dimen.button_height)),
            colors = ButtonDefaults.buttonColors(
                backgroundColor = Color.Blue,
                contentColor = Color.White
            ),
        ) {
            Text(
                text = stringResource(id = R.string.booking_screen_confirm_button),
                modifier = Modifier.align(Alignment.CenterVertically),
                fontWeight = FontWeight.Bold
            )
        }
    }
}

更新我的最终解决方案变成下面这个。我必须移动填充和背景到框（）层，以实现在垂直和水平中心的文字。

Box(
            contentAlignment = Alignment.Center,
            modifier = Modifier
                .height(32.dp)
                .padding(start = baselineGrid)
                .fillMaxWidth()
                .background(color = colorResource(id = R.color.colorPrimaryDark))
        ) {
            Text(
                text = stringResource(id = R.string.booking_screen_msg),
                color = colorResource(id = R.color.white),
                style = TextStyle(textIndent = TextIndent(firstLine = TextUnit(16F, TextUnitType.Sp))),
                textAlign = TextAlign.Center,
/*                modifier = Modifier
//                .height(componentSpace)
                    .height(32.dp)
                    .padding(start = baselineGrid)
                    .fillMaxWidth()
                    .background(color = colorResource(id = R.color.colorPrimaryDark))*/
            )
        }
