Android 谷歌地图标记被缩放时的边框替换
我在片段内部和最近使用SupportMapFragment进行集群。Google Play服务更新至9.0.83后，Google单一地图标记将被缩放时的边框所取代。只替换单个标记，簇标记可以。更改应用程序清单中的硬件加速参数不会更改任何内容。如何修复它 附言Android 谷歌地图标记被缩放时的边框替换,android,google-maps,google-play-services,Android,Google Maps,Google Play Services,我在片段内部和最近使用SupportMapFragment进行集群。Google Play服务更新至9.0.83后，Google单一地图标记将被缩放时的边框所取代。只替换单个标记，簇标记可以。更改应用程序清单中的硬件加速参数不会更改任何内容。如何修复它 附言 根据tyczj的说法，当Google Play服务（专有二进制文件）更新到9.0.x时，这种情况就开始发生了 从Github问题讨论的外观来看，解决方法是： 从gmaps api问题页面查找可能的工作区域： 改变 setIcon（Bitm
根据tyczj的说法，当Google Play服务（专有二进制文件）更新到9.0.x时，这种情况就开始发生了 从Github问题讨论的外观来看，解决方法是： 从gmaps api问题页面查找可能的工作区域： 改变 setIcon（BitmapDescriptorFactory.fromResource（R.drawable.drawableid）） 到 marker.setIcon（BitmapDescriptorFactory.fromBitmap）（BitmapFactory.decodeResource（getResources（））， R.drawable.drawableid））//可能会影响一般内存消耗 tho（？），我测试的应用程序没有超过 问题 还注意到： 我可以证实这个问题。除了@Mavamaarten，您不能 重用标记图像
（来源：）我使用简化版的@bishop87解决方案。还为集群位图添加了缓存，这使其更加安全 如果没有群集渲染器，请使用此渲染器或将此代码移到自己的渲染器： SimpleClusterRenderer.java
