线和绘图Android版中的谷歌地图绘制顺序 [英] Lines and drawables draw order in Android Google Maps

问题描述

对不起，我的英语;-P！

sorry for my english ;-P!

我正在写一个应用程序，显示在谷歌地图管道和阀门（线和点）。对于我两班。

I'm writing an app that shows in google maps pipes and valves(lines and points). For that i've two classes.

一位来自ItemizedOverlay延伸，我添加到地图叠加一个阀门的每一类，每一个可以有多个项目。

One extends from ItemizedOverlay, and i add to map overlay one for each category of valve, and each one can have more than one item.

第二，从覆盖延伸，在抽签方法Y绘制在画布的方法DrawLine的就行了。

The second extends from Overlay, and in the draw method y draw the line with the method drawline of the canvas.

我的问题是，该线被绘制在ItemizedOverlay项，无论我将它们添加到调用MapView.getOverlays（次序）。

The problem i've is that the lines are drawn over the ItemizedOverlay items, no matter the order i add them to the mapView.getOverlays().

我想在所有叠加底部的线条。有没有办法做到这一点。

I want the lines on the bottom of all overlays. is there a way to do that.

非常感谢。

推荐答案

我已经解决了！我不知道，当你填充itemizedovelay项目，他们会自动被添加到地图中，所以我加入lineoverlays之前填充它们之后，我再次加入他们。

I've solved it! I didn't know that when you populate the itemizedovelay items, they automatically are added to the map, so i was populating them before adding the lineoverlays and after that i were adding them again.

将它们添加到getOverlays（）顺序会影响正常！

The order you add them to getOverlays() affects correctly!!
