compose Android Dialog封装

Compose的特性，UI必须要埋进主布局壳子里，通过boolean值控制显示隐藏

@OptIn(ExperimentalUnitApi::class)
@Composable
fun CustomerHintDialog(alertDialog: MutableState<Boolean>, title: String, message: String) {
    if (alertDialog.value) {
        Dialog(onDismissRequest = {
            alertDialog.value = false
        }) {
            Column(
                modifier = Modifier.fillMaxWidth().padding(24.dp).background(
                    Color.White,
                    RoundedCornerShape(6.dp)
                )
            ) {
                Text(
                    "$title",
                    fontSize = TextUnit(16f, TextUnitType.Sp),
                    color = Color.Black,
                    textAlign = TextAlign.Center,
                    fontFamily = FontFamily(
                        android.graphics.Typeface.DEFAULT_BOLD
                    ),
                    modifier = Modifier.align(Alignment.CenterHorizontally)
                        .padding(vertical = 15.dp, horizontal = 12.dp)
                        .fillMaxWidth()
                )
                Text(
                    "$message",
                    fontSize = TextUnit(13f, TextUnitType.Sp),
                    color = Color.Gray,
                    modifier = Modifier.align(Alignment.CenterHorizontally).fillMaxWidth()
                        .verticalScroll(rememberScrollState())
                        .padding(vertical = 8.dp, horizontal = 12.dp)
                )
                Row(modifier = Modifier.padding(vertical = 8.dp, horizontal = 12.dp)) {
                    TextButton(
                        onClick = {
                            alertDialog.value = false
                        },
                        content = {
                            Text(
                                "取消",
                                fontSize = TextUnit(16f, TextUnitType.Sp),
                                color = Color.Gray
                            )
                        },
                        border = BorderStroke(0.5.dp, Color.Gray),
                        modifier = Modifier.weight(1f)
                    )
                    Spacer(Modifier.width(10.dp))
                    TextButton(
                        onClick = {
                            alertDialog.value = false
                        },
                        content = {
                            Text(
                                "确认",
                                fontSize = TextUnit(16f, TextUnitType.Sp),
                                color = Color.White
                            )
                        },
                        colors = ButtonDefaults.buttonColors(
                            containerColor = MaterialTheme.colorScheme.primary,
                            contentColor = Color.White
                        ),
                        modifier = Modifier.weight(1f)
                    )
                }
            }
        }
    }

}

调用方式在主布局定义一个boolean类型的mutableState，在定义一个按钮触发控制true或false显示隐藏

var isShowing by remember {
    mutableStateOf(mutableStateOf(false))
}
Button(onClick = { isShowing = mutableStateOf(true) },Modifier.fillMaxWidth().wrapContentHeight().padding(horizontal = 12.dp)) {
    Text(text = "弹框")
}
CustomerHintDialog(isShowing, "Title", "Description")
