compose Text和TextField简单使用

@Composable
fun SimpleText() {
  Text("Hello World")
}
复制代码

Text(
        text = "Hello $name!",
        color = Color.Green,//文字颜色
        fontSize = 40.sp,//文字字体大小
        fontStyle = FontStyle.Italic,//斜体
        fontWeight = FontWeight.Bold,//文字加粗
        modifier = Modifier.fillMaxSize(1f)
    )

        withStyle(style = SpanStyle(color = Color.Red, fontSize = 20.sp)) {// SpanStyle类似于Span标签，是行内元素

            withStyle(style = SpanStyle(color = Color.Cyan, fontSize = 20.sp)) {//ParagraphStyle不能设置颜色，所以这里要再套一层Style
                append("重要的事另起一行说：因为说实话，我只是个菜鸟")
