Question

当试图像这样膨胀View时：

val lay: LayoutInflater = getSystemService(LAYOUT_INFLATER_SERVICE) as (LayoutInflater)
mView = lay.inflate(R.layout.dialog_new_order, null)

我看到一个膨胀的例外：

二进制XML文件行＃0：无法解析索引1处的属性： TypedValue {t = 0x2 / d = 0x7f030006 a = -1}

但是当在活动中写相同的行时，它正常工作！

查看XML：

Answer 1

按照说法Alessio，这是正确的服务没有UI所以如果你想从你的服务中显示关于活动的视图然后通过，你就不能使用inflater您的Activity Context和展示View

LayoutInflater lay=(LayoutInflater)Context.getSystemService(LAYOUT_INFLATER_SERVICE)

mView = lay.inflate(R.layout.dialog_new_order, null)

在Service
