如标题所示，我尝试将自己的图像放在地图上的注释中。为此，我使用以下代码：
annotation.setImagePath (mImagePath);
annotation.setImageSize (4096);
annotation.setOffset (mSKScreenPoint));
没有错误，但什么也没有出现。
然而，我遵循了文档的指示：
"Sets the absolute path of the image file to be added as an annotation.
The picture must be a square image and the size must be a power of 2.
_ (32x32, 64x64, etc.)."
我的图像大小为 64 * 64。
多亏了这篇文章，我有了第一个迹象，但没有出现：
所以我将我的图像转换为 png-24 但仍然没有结果。((
在 2.1.0 中，我们添加了对使用资源包中的图像的支持并扩展了完整路径图像的示例 - 这是更新后的 prepareAnnotations 代码：
更新：添加了 2.2.0 customView 支持：
/**
* Draws annotations on map
*/
private void prepareAnnotations() {
// get the annotation object
SKAnnotation annotation1 = new SKAnnotation();
// set unique id used for rendering the annotation
annotation1.setUniqueID(10);
// set annotation location
annotation1.setLocation(new SKCoordinate(-122.4200, 37.7765));
// set minimum zoom level at which the annotation should be visible
annotation1.setMininumZoomLevel(5);
// set the annotation's type
annotation1.setAnnotationType(SKAnnotation.SK_ANNOTATION_TYPE_RED);
// render annotation on map
mapView.addAnnotation(annotation1, SKAnimationSettings.ANIMATION_NONE);
SKAnnotation annotation2 = new SKAnnotation();

mapView.centerMapOnPosition(new SKCoordinate(-122.4200, 37.7765));
}
如果您的图像是 64*64，则应将图像大小设置为 64。
annotation.setImageSize(64);
