用于合成预览的Studio BumbleBee“呈现问题”

Question

我无法在Studio中预览任何东西，扩展到像Text这样简单的东西。我得到了一个“呈现错误”，显示了这个堆栈跟踪。

java.lang.NoSuchMethodException: com.<packageName>.Navigation_ComponentsKt.<PreviewName>

这似乎只是在大黄蜂工作室之前的两到三次更新之后才发生的，而且它引起了很多的不适。

我刚刚意识到，我可能应该把这个问题作为一个问题提交给问题追踪者，但是现在我已经输入了这个问题，我不会浪费这个辛苦的工作。

撇开笑话不说，如果有人之前偶然发现了这一点，并且可能有一个解决办法，请分享。这是已知的AGP或其他组件吗？解决办法是受欢迎的。

谢谢

Answer 1

步骤1:使用最新版本的

    implementation "androidx.compose.ui:ui-tooling:1.0.1"

步骤2:设置systemUi和showBackground

@Preview(showSystemUi = true, showBackground = true)
@Composable
fun ModifierPreview() {

Text("hello world")
}

步骤3:第一次运行应用程序.

如果不运行应用程序，它将显示错误。因此，下次第一次运行该应用程序时，请单击“刷新”。

Answer 2

快速修正

使用2020.3.1。它现在是稳定的，并支持撰写。

我已经测试过这个可组合的，它运行得很好：

@Preview(showBackground = true)
@Composable
fun Greeting(name: String = "") {
    Text(text = "Hello $name!")
}

还有什么问题吗？评论就行了。

也见

如果你想要你可以启用“互动和动画预览工具”。它在“设置”下->启用交互式和动画预览工具

这使您可以立即看到您所做的更改，而无需构建。这只适用于一些基本类型，如字符串和整数。

Answer 3

您必须在您的文件中使用不同版本的androidx工具。

implementation "androidx.compose.ui:ui-tooling:1.0.0-rc01"

如果它不起作用，尝试不同的版本，哪个版本适合你
