引用 1 楼 kechanghe0705 的回复:

ListAdapter listAdapter = new ListAdapter(CaigouActivity.this); Log.d("test", "--000--"); lstCaigou.setAdapter(listAdapter);//有时加载到这里就不向下运行 Log.d("test", "---1111--");//getCoun返回值一般是10，每次返回两次 listAdapter.notifyDataSetChanged(); CaigouActivity.this.setContentView(lstCaigou); 把上面这句改下 CaigouActivity.this.setContentView(lstCaigou); ListAdapter listAdapter = new ListAdapter(CaigouActivity.this); Log.d("test", "--000--"); lstCaigou.setAdapter(listAdapter);//有时加载到这里就不向下运行 Log.d("test", "---1111--");//getCoun返回值一般是10，每次返回两次 listAdapter.notifyDataSetChanged();

试了一下不行的放到上面去界面就直接不能动了，这一句也不运行Log.d("test", "--000--"); 放到下面去运行到lstCaigou.setAdapter(listAdapter);，就不向下运行了。

眨一看，你的代码没问题。你断点下看看吧。看看你的namelist 是不是长度为0 . 还有就是看见你没notifyDataSetChanged()。 再有就是你注意下自己的逻辑顺序。 查下吧，应该就是这几点出问题了。

[dengqiang2016]

长度不为0的，android还不懂如何断点测试。java程序测试过了的。

[迷px]

楼主解决没，能分享下不

[dengqiang2016]

最主要的是android4.0后访问网络不能再主线程里面，要程序开一个子线程，但是显示数据要在主线程里面处理。

@Override public Object getItem(int position) { Log.d("testgetItem", String.valueOf(nameList.get(position))); return nameList.get(position); } //return 有问题把 return position；
