Question

我有一个应用程序，它使用地图活动作为整个应用程序的一部分，当我放大和缩小时，我得到内存不足错误。我只有一个叠加项目。不知道怎么解决这个问题？这是我的下面的xml，它是完全嵌套的。

Answer 1

您的布局中嵌套了很多ImageView。不幸的是，图像加载和位图可以是PITA。已知ImageView会导致OutOfMemoryErrors。特别是当他们从代码中填充Bitmaps时。

要解决此问题，请删除ImageView并检查错误是否仍然存在。

如果它解决了错误，请重新考虑在MapView上显示图像的策略。同样使用density-dependent资源可能有助于在一定程度上解决问题。

编辑：在查看堆栈跟踪后，其中显示：“位图超出VM预算”我确信您的图像加载策略需要改进。

缩放时，Android MapView会出现内存不足错误
