Answer 1

if (b.getInt(ConfigDataFieldHelper.BundleDataFields.DATARESULTFIELD) == ConfigDataFieldHelper.BundleDataResult.DataEmpty)
{
List<Map<String, Object>> lstMapsNull = (List<Map<String, Object>>) b
.get(ConfigDataFieldHelper.BundleDataFields.DATA);
SimpleAdapter adapterNull = new SimpleAdapter(
WorkOrderList.this, lstMapsNull,
android.R.layout.simple_list_item_1,
new String[]
{
"Msg"
}, new int[]
{
android.R.id.text1
});
lstWorkOrder.setAdapter(adapterNull);
}

Answer 2

else if (b.getInt(ConfigDataFieldHelper.BundleDataFields.DATARESULTFIELD) == ConfigDataFieldHelper.BundleDataResult.DataSuccessfully)
{
lstMaps = (List<Map<String, Object>>) b
.get(ConfigDataFieldHelper.BundleDataFields.DATA);
adapter = new SimpleAdapter(WorkOrderList.this,
lstMaps, R.layout.work_order_list_items,
new String[]
{
"OrderId", "Unit", "Type", "OrderDate",
"Description"
}, new int[]
{
R.id.work_order_list_item_orderid,
R.id.work_order_list_item_unit,
R.id.work_order_list_item_type,
R.id.work_order_list_item_date,
R.id.work_order_list_item_description
});
lstWorkOrder.setAdapter(adapter);

lstWorkOrder.setOnItemClickListener(lstOrderItem);
}
如果出话，总是会在红色这里出错

Answer 3

看log是不能在子线程更新UI。你可以用handler来更新。
