如果用户点击“提交”按钮并关闭键盘选项，则在用户输入数据并且不关闭键盘选项的情况下，在客户名称选项菜单搜索中有尚未解决的错误，在这种情况下我们从服务器获取数据。在另一种情况下，如果用户在搜索字段中输入数据并立即关闭键盘选项，然后单击“提交”按钮，在这种情况下，数据不会显示在列表视图的弹出框中。

在这里通知......
private void displayData1(String response){JSONObject responseObj = null;
try
{
Gson gson = new Gson();
responseObj = new JSONObject(response);
Log.d("TestTag", "Response from server displaydata:"+response);
JSONArray ListObj = responseObj.getJSONArray("customerSearchList");
//list = new ArrayList<ProjectVO>();
for (int i=0; i<ListObj.length(); i++)
{
String info = ListObj.getJSONObject(i).toString();
ProjectVO list1 = gson.fromJson(info, ProjectVO.class);
searchList.add(list1);
Log.d("TestTag","searchList"+searchList.toString());
}
dataAdapter.notifyDataSetChanged();
}
catch (JSONException e) {
e.printStackTrace();
}}
试试这个。
