获得autocompletetextview位置 [英] get position in autocompletetextview
本文介绍了获得autocompletetextview位置的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有两个autocompletetextviews，在第一autocompletetextview我使用JSON正从服务器的项目，对于下面是响应
<$p$p><$c$c>{\"status\":\"success\",\"clientlist\":[{\"cid\":\"1\",\"name\":\"margi\"},{\"cid\":\"2\",\"name\":\"steven\"}],\"productboxtype\":[{\"pbxid\":\"1\",\"pbxname\":\"1打，qtyperbox：12}，{pbxid：2，pbxname：2数十，qtyperbox：24}，{pbxid：3，pbxname ：3数十，qtyperbox：36}]}我能够在我的第一个自动完成获得的名称和它工作正常，
现在的问题是假设用户选择项摩尔吉，其CID是1，所以我再次发送请求到服务器，并试图让摩尔吉的productnames，其响应
{地位：成功，clientproduct：[{PID：4，名：康安pair\",\"unitprice\":\"1500\",\"boxqty\":\"1\",\"bulkprice\":[{\"minqty\":\"10\",\"price\":\"1500\"},{\"minqty\":\"15\",\"price\":\"1470\"},{\"minqty\":\"20\",\"price\":\"1460\"}]}]}

解决方案
使用 list1的获取选定 CID 从ListView的：
@覆盖
公共无效onItemClick（适配器视图＆LT;＆GT;母公司，观景，
INT位置，长的id）{
// TODO自动生成方法存根
JsonParseClientProduct JP =新JsonParseClientProduct（）;
清单＆LT; SuggestGetSetClientProduct＆GT; list1的= jp.getParseJsonWCF（
。autoproduct.getText（）的toString（））;
新AttemptLogin（list1.get（位置）.getId（））执行（）;
}
和创建 AttemptLogin 构造类：
类AttemptLogin扩展的AsyncTask＆LT;字符串，字符串，字符串＆GT; { 布尔失败= FALSE;
私人ProgressDialog pDialog;
私人INT selected_cid = 1;
AttemptLogin（INT selected_cid）{
this.selected_cid = selected_cid;
}
// ...您code
}
现在使用 selected_cid 的补充 CID 作为参数：
params.add（新BasicNameValuePair（CID，selected_cid）;
I have two autocompletetextviews,in first autocompletetextview i am getting items from server using json,the following is response for that
{"status":"success","clientlist":[{"cid":"1","name":"margi"},{"cid":"2","name":"steven"}],"productboxtype":[{"pbxid":"1","pbxname":"1 Dozen","qtyperbox":"12"},{"pbxid":"2","pbxname":"2 Dozens","qtyperbox":"24"},{"pbxid":"3","pbxname":"3 Dozens","qtyperbox":"36"}]}
i am able to get names in my first autocomplete and it works fine,
Now issue is suppose user select item "margi" and its cid is 1,so again i am sending request to server and trying to get productnames of 'margi',and its response is
{"status":"success","clientproduct":[{"pid":"4","name":"kangan pair","unitprice":"1500","boxqty":"1","bulkprice":[{"minqty":"10","price":"1500"},{"minqty":"15","price":"1470"},{"minqty":"20","price":"1460"}]}]}

// catid=list.get(i).getId();
}
for(int b=0;b<list.size();b++)
{
catidtemp=list.get(0).id.toString();
System.out.println("cattttttiiiiddd????"+catidtemp);
}
解决方案
Use list1 for getting selected cid from ListView:
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
JsonParseClientProduct jp=new JsonParseClientProduct();
List<SuggestGetSetClientProduct> list1 =jp.getParseJsonWCF(
autoproduct.getText().toString());
new AttemptLogin(list1.get(position).getId()).execute();
}
and create constructor in AttemptLogin class:
class AttemptLogin extends AsyncTask<String, String, String> {
boolean failure = false;
private ProgressDialog pDialog;
private int selected_cid=1;
AttemptLogin(int selected_cid){
this.selected_cid=selected_cid;
}
//... your code
}
now use selected_cid for to add cid as parameter :
params.add(new BasicNameValuePair("cid",selected_cid);
