更新 MergeAdapter 的内容
我有一个非常漂亮的 MergeAdapter，其中包含一堆自定义视图和一些自定义 ListAdapter。此 MergeAdapter 驱动一个 ListActivity，该 ListActivity 显示每 x 秒更新一次的内容。
目前，我只是创建一个新的 MergeAdapter，创建并添加所有自定义视图（其中包括一些 ImageView） - 并在我的活动中的 ListView 上调用 setAdapter。
大约 10 分钟的更新后，我耗尽了堆空间并崩溃了。
最终因为添加了新的 ImageView，并引发了以下异常：
Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget
使用更简单的适配器（如 ArrayAdapter），我只需更新数据集，然后调用
notifyDataSetChanged()
适配器。
是否有类似/推荐的方法来“更新” MergeAdapter？或者我应该遍历潜在复杂的 MergeAdapter 的内容并更新单个视图？
I have a pretty nifty MergeAdapter that contains a bunch of custom views and some custom ListAdapters. This MergeAdapter drives a ListActivity that displays content that get's updated every x seconds.
Currently I just create a new MergeAdapter, create and add all of my custom views (and this includes a few ImageViews) - and call setAdapter on the ListView in my activity.
After about 10 minutes of updates I run out of heap space and crash.
Ultimately because a new ImageView is added, and the following exception is thrown:
Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget
With simpler adapters (like ArrayAdapter), I would just update the data set, and call
notifyDataSetChanged()
on the adapter.
Is there a similar/recommended approach for "updating" a MergeAdapter? Or should I be walking the contents of a potentially complex MergeAdapter and updating individual Views?

notifyDataSetChanged()有效，据我所知。当前的MergeAdapter具有将其内部的ListAdapters的任何更改传递到MergeAdapter中已注册的更改兴趣的代码。这可能还没有经过足够的测试，所以如果您有一个示例应用程序来演示其他情况，请发布指向它的链接或将其发送给我（提及这个SO问题）。notifyDataSetChanged()works, AFAIK. The currentMergeAdapterhas the code to ripple any changes fromListAdaptersinside it to whatever has registered interests in changes in theMergeAdapter. This probably has not been tested enough, so if you have a sample app that demonstrates otherwise, post a link to it or send it to me (mention this SO question).
