Question

您好我在Primefaces中阅读了有关gmap的文档，我根据文档说明了这些：

<script src="https://maps.googleapis.com/maps/api/js? key=YOUR_API_KEY&callback=initMap" async defer></script>

我用谷歌API密钥替换了YOUR_API_KEY并删除了它们之间的空格？和键

和

<p:gmap center="41.381542, 2.122893" zoom="15" type="hybrid" style="width:600px;height:400px" />

但是当我渲染页面时出现错误：

对实体“回调”的引用必须以“;”结尾分隔符。

所以我在google上搜索了&并将&替换为<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap" async defer></script>，该行

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&amp;callback=initMap" async="async" defer></script>

然后我有错误

与元素类型“script”关联的属性名称“async”必须后跟“=”字符。

在Google上阅读我将其更改为

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&amp;callback=initMap" async="async" defer="defer" ></script>

然后我有错误

与元素类型“script”关联的属性名称“defer”必须后跟“=”字符。

在Google上阅读我再次更改了

open class PopupActivity(): AppCompatActivity() {

  public var message:String = "This is a message string for the label"

  val titleLabel: TextView by lazy {
    val label = TextView(this)
    label.gravity = Gravity.CENTER
    label.setTextSize(Constants.FontSizePopupTitle)
    return@lazy label
  }

  val popupView: ConstraintLayout by lazy {
    val view = ConstraintLayout(this)
    view.setBackgroundColor(Color.primary())
    return@lazy view
  }

  val view: ConstraintLayout by lazy {
    val v = ConstraintLayout(this)
    return@lazy v
  }

  @SuppressLint("ResourceType")
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    view.id = 1
    popupView.id = 2
    titleLabel.id = 5

    var margin = 2 * Constants.SpacingStandard.toInt()

    view.addView(popupView)
    popupView.addView(titleLabel)

    titleLabel.layoutParams = ConstraintLayout.LayoutParams(
      ConstraintLayout.LayoutParams.MATCH_CONSTRAINT,
      ConstraintLayout.LayoutParams.WRAP_CONTENT)
    titleLabel.text = message


    popupView.layoutParams = ConstraintLayout.LayoutParams(
      ConstraintLayout.LayoutParams.MATCH_CONSTRAINT,
      ConstraintLayout.LayoutParams.WRAP_CONTENT)

    val popupConstraintSet = ConstraintSet()

    popupConstraintSet.connect(popupView.id, START, view.id, START, margin)
    popupConstraintSet.connect(popupView.id, END, view.id, END, margin)
    popupConstraintSet.centerHorizontally(popupView.id, view.id)
    popupConstraintSet.centerVertically(popupView.id, view.id)

    view.setConstraintSet(popupConstraintSet)
    setContentView(view)
  }
}

然后我有这些错误：

ReferenceError：谷歌未定义

未捕获异常：InvalidValueError：initMap不是函数

我做错了什么？

以下应该有效

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY></script>
