Question

我搜索了这个问题，我发现了一些有关相同的stackoverflow问题，但不知道如何解决问题。

我创建了一个活动，我想添加一个非常小的mapview（如140w X 70h）。它只是展示了这个地方的小预览。当您点击这个小地图视图时，您会获得一个带有空洞地图的新活动。

MapView的：

<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"/>

logcat的：

这是错误。当我使用fill_parent时它可以工作，但我不想要一个带有fill_parent的mapview。

也许你们知道另一种方法来获取地图上当前（或给定）位置的预览小图像作为图像。是不是可以显示一个小的mapview？

谢谢

Answer 1

如果您只想在没有互动的情况下展示静态地图，我建议您使用谷歌的static map api。您可以定义标记，中心，大小和一些标签，并返回生成的图像，可以在ImageView中轻松显示。这样做的好处是：您不必为一个小的地图图像调用完整的MapView。没有内存或用户交互的开销。适合你的情景。

将MapView设置为特定宽度和高度后的Google API MapView OutOfMemory
