"IBitmapDescriptorFactory未初始化“错误
"IBitmapDescriptorFactory未初始化“错误
提问于 2012-12-18 23:03:19
我正在尝试在Google Maps Android API v2中获取一个带有自定义图标的标记。我刚刚改变了Google提供的一个例子。我在方法setUpMap().中向RawMapViewDemoActivity添加了.icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow))
private void setUpMapIfNeeded() {
if (mMap == null) {
mMap = ((MapView) findViewById(R.id.map)).getMap();
if (mMap != null) {
setUpMap();
}
}
}
private void setUpMap() {
mMap.addMarker(new MarkerOptions()
.position(new LatLng(0, 0))
.title("Marker")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));
}但是我总是收到一个"IBitmapDescriptorFactory is not initialized“的提示。

在使用此类中的任何方法之前，必须执行以下操作之一以确保初始化此类：
- 等待GoogleMap从您添加到应用程序中的MapFragment或MapView变为可用。您可以通过调用getMap()方法并检查返回的对象是否不为空来验证GoogleMap是否可用。
- 调用MapsInitializer.initialize(Context)。只要没有抛出com.google.android.gms.common.GooglePlayServicesNotAvailableException GooglePlayServicesNotAvailableException，这个类就会被正确地抛出
我做了第一个，但仍然得到这个错误。有什么建议吗？

将您的代码移动到onMapReady()，这是由GoogleMaps提供的回调。
