更正下 ListView != null 或是ListView.size() >0 [/quote] 在哪里加保护呢

数组越界啊，字数补丁.exe

更正下 ListView != null 或是ListView.size() >0 [/quote] 在哪里加保护呢[/quote] 从你贴的log看应该是这里HeaderViewListAdapter.java:164，这个地方应该是你代码里调用了ArrayList.get(index)，而你的list不知道为什么为null所以导致你取值的时候越界了 at java.util.ArrayList.get(ArrayList.java:304) at android.widget.HeaderViewListAdapter.isEnabled(HeaderViewListAdapter.java:164)

[peter_nj_RD]

ArrayList的get方法里面会去判断你传的index如果大于等于ArrayList的size值就会throw这个exception。log里面你查询的index=0还越界，说明你的ArrayList是个null的

已经找到问题点了，是在判断那里出的问题返回的解析数据那里出的问题，不是自己写的代码，问题太难找了 //返回解析的数据 if ((curPage - 1) * pageSize + curcount >= allCount) { isCompetition = true; Message msg1 = new Message(); msg1.getData().putInt("index", 5); sendMessageToHandler(msg1); }
