我在我的 Android 应用程序中有一个带有 a MapViewin a的布局ViewSwitcher（它是在 a 中RelativeLayout，而不是整个屏幕）。

我的问题是点击该项目非常慢，点击几下后它会触发java.lang.OutOfMemoryError（在设备和模拟器上）。

所以我的问题是：真正导致此错误的原因是什么？

  1. 这不是全屏MapView吗？

    我遵循了这篇文章的解决方案：android MapView 总是在嵌套元素中导致 OutOfMemoryError但它没有做任何事情。

  2. 是因为ViewSwitchertheMapView和它的另一个孩子 (a ListView) 都在内存中吗？

    如果是这样，我怎样才能让android重绘每个视图showNext()？

当我有两个不同的活动而不是ViewSwitcher，并且当MapView整个布局运行良好时，它是什么问题，我该如何改变它？
