When I got to work in a new company, I looked at other people's projects, debugged the bugs, and found that the map was refreshed in one second, and Baidu map was flashing. According to the previous Baidu Map Project, I did not encounter this situation, but I also did not flash when I frequently added the cover and refreshed it. Later I looked at the previous Cod

Because there are many types of overlays in a map, because of an overlay (which is generally custom), only one occurrence is allowed throughout the mapThe first thing to think about is that each time you create this type of overlay, clear this type of covering, a simple way to judge the type of cover instanceof, part of the code is as follows (red code is the foc

People who have worked on Android map application development know that the popular map frameworks are Google, Baidu, and AMAP. For map development on Google and Baidu, you must obtain an api key before being authorized to develop applications. AMAP does not need to be so troublesome. Therefore, this article uses AMAP to develop a simple DEMO. Before you start, y

to our GIS part, need mobile phone group, MIS Group, real group, etc., all need to save the data for the coordinates of the Baidu coordinate system, so each group docking up is more convenient. However, the data saved at this time is the data in the Baidu coordinate system, and if it is to be used by other companies, it has to be re-calculated as the coordinates of the universal coordinate system.Can be seen, the use of large projects is still a lot of inconvenience. However, this issue is the

Follow the official demo after deployment. Add a cover.Required classes:The Bitmapdescriptor bitmap Image object is used to display the area of the overlay.Mapview the primary object has a control instantiation on the page.Baidumap has Mapview.getmap (); Map object.

Google Maps API version 3rd providesOverlayViewClass.OverlayViewIs a base class that provides several methods you must implement when creating a stack. This class also provides some methods for converting between screen coordinates and map locations. To create a custom stack layer, perform the following operations: SetprototypeSetgoogle.maps.OverlayView(). This effectively achieves "subclass" of stack layer classes ".

With the enhancement of the computing ability of terminal equipment, users need more and more interactive effect when they use the map.For example, in today's very hot indoor navigation, in order to get a good user experience, it is necessary to change the color of the store when a user clicks on a store. This requires that vector layers be superimposed.How can I overlay a vector layer on top of a tile map,
