Android Compose 控件学习八（PartialBottomSheet）

一、导入库

    implementation("androidx.navigation:navigation-common:2.8.9")
    implementation("androidx.navigation:navigation-compose:2.8.9")
    implementation("androidx.compose.material3:material3:1.3.2")
    implementation("androidx.compose.material3.adaptive:adaptive:1.1.0")
    implementation("androidx.compose.material3.adaptive:adaptive-layout-android:1.1.0")
    implementation("androidx.compose.material3.adaptive:adaptive-navigation-android:1.1.0")
    implementation("androidx.compose.material3.adaptive:adaptive-navigation:1.1.0")
    implementation("androidx.compose.material3:material3-adaptive-navigation-suite:1.3.2")
    implementation("androidx.compose.material:material:1.8.0")
    implementation("androidx.compose.material:material-icons-extended:1.7.8")
    implementation("androidx.compose.material:material-icons-core:1.7.8")
    implementation("androidx.compose.material3:material3-window-size-class:1.3.2")

二、示例代码

@Composable
fun PartialBottomSheet() {
    var showBottomSheet by remember { mutableStateOf(false) }
    val sheetState = rememberModalBottomSheetState(
        skipPartiallyExpanded = false,
    )

    Column(
        modifier = Modifier.fillMaxWidth(),
        horizontalAlignment = Alignment.CenterHorizontally,
    ) {
        Button(
            onClick = { showBottomSheet = true }
        ) {
            Text("Display partial bottom sheet")
        }

        if (showBottomSheet) {
            ModalBottomSheet(
                modifier = Modifier.fillMaxHeight(),
                sheetState = sheetState,
                onDismissRequest = { showBottomSheet = false }
            ) {
                Text(
                    "Swipe up to open sheet. Swipe down to dismiss.",
                    modifier = Modifier.padding(16.dp)
                )
            }
        }
    }
}
