请大家帮忙看看错误在哪，我也不知道我解析对不对，线程也没摸到门。
服务器返回的Json是：
{
"a":["一"."二"],
"b":{"1":"1","2":"2"},
"c":{"1":"3","2":"4"},
"d":{"1":"5","2":"6"},
"e":{"1":"7","2":"8"}
}
客户端代码（没有放上导入包）：
public class MainActivity extends ActionBarActivity {
Context myContext;
//public Thread myThread;
EditText username;
EditText userpwd;
ListView myListView;
Button ok;
String uname1;
String pwd1;
String resultString;

List<Map<String, Object>> listItems = null;
private Handler myHandler;
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
username=(EditText)findViewById(R.id.uname);
userpwd=(EditText)findViewById(R.id.pwd);
myListView=(ListView)findViewById(R.id.item);
ok=(Button)findViewById(R.id.submit);
myHandler = new Handler()
{
@Override

myListView.setAdapter(simpleAdapter);
}
}

ok.setOnClickListener(new View.OnClickListener()

try {

listItems=new ArrayList<Map<String,Object>>();
for (int i = 0; i < km.length(); i++)
{
Map<String, Object> listItem=new HashMap<String,Object>();
listItem.put("km", km.getString(i));
listItem.put("cj", cj.optString(i+"1","无"));
listItem.put("xs", xs.optString(i+"1","无"));
listItem.put("xf", xf.optString(i+"1","无"));
listItem.put("zt", zt.optString(i+"1","无"));
listItems.add(listItem);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
myHandler.sendEmptyMessage(0x123);
}
}
}
看着没啥问题，现在解决了吗？
