Question

jetpack组合高程渲染出现问题。我正在尝试在Surface上添加高程，但是我的UI似乎带有修剪的阴影。另外，如何在Surface上添加彩色阴影？

请参阅以下屏幕截图

@Composable
fun DiscoverItem() {
    Surface(
        contentColor = Color(0xFFFFFFFF),
        modifier = Modifier.preferredWidthIn(min = 145.dp).preferredHeight(56.dp),
        shape = CircleShape,
        elevation = 8.dp,
    ) {
        Row(
            modifier = Modifier.fillMaxSize().padding(horizontal = 8.dp),
            verticalAlignment = Alignment.CenterVertically
        ) {
            Surface(
                modifier = Modifier.preferredSize(40.dp),
                shape = CircleShape,
                color = Color(0xFFFFC3D8)
            ) {
                Image(
                    imageResource(R.drawable.pin_icon),
                    modifier = Modifier.size(width = 18.dp, height = 24.dp),
                    contentScale = ContentScale.Fit
                )
            }
            Spacer(modifier = Modifier.padding(start = 10.dp))
            Text(
                "YOUR AREA",
                style = MaterialTheme.typography.body2,
                color = Color(0xFFFC1055)
            )
        }
    }
}

@Composable
@Preview
fun DiscoverItemPreview() {
    DiscoverItem()
}

布局底部没有足够的内容。您可以添加间隔以查看阴影。

const functions = require('firebase-functions');
const admin = require('firebase-admin')
admin.initializeApp();

exports.updateViewCount = functions.https.onCall((data, context) => {

    const postId = data.postId;
    const userId = data.uid;
    console.log("postId: " + postId + ", userId: " + userId);

    const postsRef = admin.database().ref('/posts/${postId}/views_count');

    // not sure what to do to update the views_count key using a Transaction from this point on
});

关于彩色阴影，compose min sdk是Android Lollpop，棒棒糖的Skia版本不支持彩色阴影/高程。利兰·理查森（Leland Richardson）在YouTube上有关“撰写狗粮”的视频中谈到了这个问题。 here

为什么用jetpack组成高程剪辑我的影子？
