连接webservice的那个方法HttpConnSoap应该是没问题的因为数据库的增删都是可以的，就是无法实现这个显示所有信息到LISTVIEW中的这个功能不知道为什么，LOGCAT中也是一片绿没什么问题
LOGCAT中的信息：

============解决方案1============
分析原因就是在线程还没有执行完时候，getAllInfo早已执行完毕以后，，所以在执行for (int j = 0; j < crrayList.size(); j += 3)时候， crrayList为零行。你取出的LOGCAT是执行请求以后的返回数据，这时候setListView方法早已经走完，所以只有一行数据。截图中的一行数据来自
HashMap<String, String> tempHash = new HashMap<String, String>();
tempHash.put("Cno", "Cno");
tempHash.put("Cname", "Cname");
tempHash.put("Cnum", "Cnum");
list.add(tempHash);
使用Thread应该配合Handler来使用。
我把代码修改一下
private final static int REQUEST_SUCCESS = 1; private final static int REQUEST_FALSE = 0; private void RequestData() { arrayList.clear(); brrayList.clear(); crrayList.clear(); new Thread(new Runnable() { @Override public void run() { // TODO Auto-generated method stub crrayList = Soap.GetWebServre("selectAllCargoInfor", arrayList, brrayList); Message msg = new Message(); if(crrayList.size()>0) { msg.what = REQUEST_SUCCESS; } else { msg.what = REQUEST_FALSE; } // 发送消息 mHandler.sendMessage(msg); } }).start(); } public Handler mHandler = new Handler(){ // 接收消息 @Override public void handleMessage(Message msg) { // TODO Auto-generated method stub super.handleMessage(msg); switch (msg.what) { case REQUEST_SUCCESS: setListView(); break; case REQUEST_FALSE: // 做错误处理 break; default: break; } } }; private void setListView() { listView.setVisibility(View.VISIBLE); List<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>(); list = dbUtil.getAllInfo(); adapter = new SimpleAdapter(MainActivity.this, list, R.layout.adapter_item, new String[] { "Cno", "Cname", "Cnum" }, new int[] { R.id.txt_Cno, R.id.txt_Cname, R.id.txt_Cnum }); listView.setAdapter(adapter); } public List<HashMap<String, String>> getAllInfo() { List<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>(); HashMap<String, String> tempHash = new HashMap<String, String>(); tempHash.put("Cno", "Cno"); tempHash.put("Cname", "Cname"); tempHash.put("Cnum", "Cnum"); list.add(tempHash); for (int j = 0; j < crrayList.size(); j += 3) { HashMap<String, String> hashMap = new HashMap<String, String>(); hashMap.put("Cno", crrayList.get(j)); hashMap.put("Cname", crrayList.get(j + 1)); hashMap.put("Cnum", crrayList.get(j + 2)); list.add(hashMap); } return list; } |
执行RequestData就可以，我没法编译，细节自己再调整看一下，应该能解决问题了。
你给的分数太少了，大牛们都不给你解答。如果解决问题就给分哈。
另外，Java多线程的操作可以系统学习一下。工作中使用极为频繁。
