谷歌API的MapView内存不足的MapView设置为特定的宽度和高度后， [英] Google API MapView OutOfMemory after setting the MapView to specific width and height

问题描述

我搜索对于这个问题，我发现差不多的，但没有任何想法如何解决这个问题的一些计算器的问题。

i searched for this Problem, and i found some stackoverflow Questions about the same but without any idea how to resolve the problem.

我创建了一个活动，我想添加一个非常小的图形页面（如140瓦特点¯x70H）。这是只显示所放的地方是一个小preVIEW。当你点击这个小图形页面，你得到一个新的膨胀与孔地图一个新的活动。

I created an activity and i want to add a really small mapview (like 140w X 70h). It is only to show a small preview of where the place is. When you click this little mapview you get a new inflate to a new activity with the hole map.

图形页面：

<com.google.android.maps.MapView android:id="@+id/mapview" 
                android:layout_width="140dip"
                android:layout_height="80dip"
                android:layout_below="@id/attributes"
                android:layout_alignParentRight="true"
                android:apiKey="****"
                android:paddingBottom="60dp"/>

这是错误。当我使用FILL_PARENT它的工作原理，但我不想用一个FILL_PARENT MapView类。

this is the error. When i use fill_parent it works, but i dont want a mapview with fill_parent.

也许你们知道另一种方式来获得地图的图像上的电流（或给出）位置的preVIEW小的图像。
是不是有可能显示一个小图形页面？

Maybe you guys know another way to get a preview small image of the current (or given) position on the map as image. Isn't it possible to show a small mapview ?

感谢

推荐答案

如果你只是想显示没有交互的静态地图我推荐的静态地图API从谷歌。可以定义标志物，该中心的规模和一些标签和它返回可以一个ImageView的内部容易地显示所生成的图像。这样做的好处：你不必调用一个完整的图形页面只是一个小地图图像。内存或用户交互的开销。适合你的方案。

If you just want to show a static map without interaction I recommend the static map api from google. You can define markers, the center, the size and some labels and it returns a generated image that can be easily shown inside a ImageView. The benefit of this: You don't have to invoke a complete MapView for just a small map image. No overhead of memory or user interaction. Perfect for the scenario you have.
