在没有单选按钮的情况下在 Jetpack Compose 中创建切换按钮组

Question

我正在尝试在我的项目中放置一个按钮切换组，与单选按钮组类似，但看起来不像单选按钮组（即选择一个按钮时，还取消选择其他按钮）。

我遵循了我在网上找到的单选按钮模式，但这似乎并没有奏效。 有没有办法做到这一点？ 我已经到了在我想要的地方有按钮的地步，但它们都被禁用了。

MovieSpotterTheme() {
                Card(
                    modifier = Modifier
                        .fillMaxWidth()
                ) {
                    @Composable
                    fun MaterialButtonToggleGroup() {
                        var selected by remember { mutableStateOf("Android") }

                        val buttonGroup = listOf("Popular Movies", "Search Movies")

                     
                        val onSelectedChange = { text: String ->
                            selected = text
                        }
                        Row(
                            horizontalArrangement = Arrangement.SpaceEvenly
                        ) {
                            buttonGroup.forEach { text ->
                                Row(Modifier
                                    .selectable(
                                        selected = (text == selected),
                                        onClick = { onSelectedChange(text) }
                                    )
                                    .padding(horizontal = 16.dp)
                                ) {
                                    Button(
                                        enabled = (text == selected),
                                        onClick = { onSelectedChange(text) }
                                    ) {
                                        Column(
                                            horizontalAlignment = Alignment.CenterHorizontally
                                        ) {
                                            Text(
                                                text = text,
                                                style = MaterialTheme.typography.body1.merge(),
                                                modifier = Modifier.padding(horizontal = 16.dp)
                                            )
                                        }
                                    }
                                }
                            }
                        }
                    }
                    Surface() {
                        MaterialButtonToggleGroup()
                    }
                }
            }

提供简化版。 玩弄它以满足您的要求。
