Answer 1

您需要将weight和fill设置为false：

    Text(
        modifier = Modifier.weight(weight = 1f, fill = false),
        text = name,
        overflow = TextOverflow.Ellipsis,
        fontWeight = FontWeight.Bold,
        fontSize = 20.sp,
        maxLines = 1
    )

你可以在 Text 组合中添加 weight 修饰符。

Row(){
    Icon()
    Text(
        text = ".....",
        overflow = TextOverflow.Ellipsis,
        fontWeight = FontWeight.Bold,
        fontSize = 20.sp,
        maxLines = 1,
        modifier = Modifier.weight(1f)
    )
    //...
}
