我需要从服务器上获取数据，并在机器人的autocompleteTextView填充。
我已经用了，我在onPerformFiltering（获取相同），并显示自定义过滤器在onPublishResults（）。

解决方案

 类ProcessUpdater扩展的AsyncTask＆LT;太虚，太虚，太虚＆GT; {            @覆盖
            保护无效doInBackground（虚空...... PARAMS）{
                // TODO自动生成方法存根                    DefaultHttpClient的HttpClient =新DefaultHttpClient（）;
                    HTTPGET HTTPGET =新HTTPGET（URL）;
                    HTT presponse响应= httpclient.execute（HTTPGET）;
                    在的BufferedReader =新的BufferedReader（新的InputStreamReader（response.getEntity（）的getContent（）））;
                    StringBuffer的SB =新的StringBuffer（）;
                    串线=;
                    串NL = System.getProperty（line.separator）;
                    而（（行= in.readLine（））！= NULL）{
                        sb.append（行+ NL）;
                    }
                    附寄（）;
                    字符串结果= sb.toString（）;
                    Log.v（我的回答::，结果）;
                    的JSONObject的JSONObject =新的JSONObject（结果）;
                    JSONArray resultArray = jsonObject.getJSONArray（过程）;
                    的for（int i = 0; I＆LT; resultArray.length（）;我++）{
                        JSONObject的C = resultArray.getJSONObject（I）
                        字符串SBS = c.getString（过程code）;
                        ProcessList.add（SBS）;
                    }
                }赶上（例外五）{
                    // TODO：处理异常
                }
                返回null;
            }
            @覆盖
            保护无效onPostExecute（虚空结果）{
                SelectProcess.setAdapter（新ArrayAdapter＆LT;串GT;（youractivtyname.this，android.R.layout.simple_dropdown_item_1line，ProcessList中））;            }

I need to fetch data from server and populate in autocompleteTextView in android. I have used a custom filter for the same where I fetch in onPerformFiltering() and display in onPublishResults(). But I need not fetch data from the server for every character Change.I need to do it for specific length of characters. How can I do this?

class ProcessUpdater extends AsyncTask <Void, Void, Void>{

            @Override
            protected Void doInBackground(Void... params) {
                // TODO Auto-generated method stub

                    DefaultHttpClient httpclient = new DefaultHttpClient();
                    HttpGet httpget = new HttpGet("url");
                    HttpResponse response = httpclient.execute(httpget);
                    BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
                    StringBuffer sb = new StringBuffer("");
                    String line = "";
                    String NL = System.getProperty("line.separator");
                    while ((line = in.readLine()) != null) {
                        sb.append(line + NL);
                    }
                    in.close();
                    String result = sb.toString();
                    Log.v("My Response :: ", result);
                    JSONObject jsonObject = new JSONObject(result);
                    JSONArray resultArray = jsonObject.getJSONArray("Process");
                    for (int i = 0; i < resultArray.length(); i++) {
                        JSONObject c = resultArray.getJSONObject(i);
                        String sbs = c.getString("ProcessCode");
                        ProcessList.add(sbs);
                    }
                } catch (Exception e) {
                    // TODO: handle exception
                }
                return null;
            }
            @Override
            protected void onPostExecute(Void result) {
                SelectProcess.setAdapter(new ArrayAdapter<String>(youractivtyname.this, android.R.layout.simple_dropdown_item_1line, ProcessList));

            }
        }
