解决方案

ANR错误

活动没有响应。

您的活动走上长说的是Android OS嘿，我还活着！ （这是在UI线程执行）。

<一个href="http://developer.android.com/guide/practices/design/responsiveness.html">http://developer.android.com/guide/practices/design/responsiveness.html

基本上，如果你做的UI线程做一些复杂的任务，它太忙着做你的任务是告诉大家，它仍然是'活'的OS。

<一个href="http://android-developers.blogspot.co.uk/2009/05/painless-threading.html">http://android-developers.blogspot.co.uk/2009/05/painless-threading.html

您应该将你的XML解析code到另一个线程，然后使用一个回调来告诉UI线程你已经完成，并做一些与结果。

解决方案

ANR Error

Activity Not Responding.

Your activity took to long to say to the Android OS 'hey i'm still alive'! (This is what the UI thread does).

http://developer.android.com/guide/practices/design/responsiveness.html

Basically if you make the UI thread do some complex task it's too busy doing your task to tell the OS that it is still 'alive'.

http://android-developers.blogspot.co.uk/2009/05/painless-threading.html

You should move your XML Parsing code to another thread, then use a callback to tell the UI thread you have finished and to do something with the result.
