我在我的应用程序中使用了Autocompletetextview并且效果很好，但我还想要一件事，用户在我的autocompletetextview中输入的字母应该出现在color.please中，我应该在代码中添加什么以便它显示我想要的......这是我的代码

class afficheclient extends AsyncTask<String, String, String> {
        InputStream is = null;
        String result = null;
        String line = null;

        /**

        @Override
        protected String doInBackground(String... params) {
            return null;
        }

        @Override
        protected void onPreExecute() {
            super.onPreExecute();


            try {

                HttpEntity entity = response.getEntity();
                is = entity.getContent();
                Log.e("Pass 1", "connection success ");
            } catch (Exception e) {

                        (new InputStreamReader(is, "iso-8859-1"), 8);
                StringBuilder sb = new StringBuilder();

                while ((line = reader.readLine()) != null) {
                    sb.append(line + "\n");
                }

                is.close();
                result = sb.toString();
                Log.e("Pass 2", "connection success ");

                    str1[i] = json.getString("D_CLIENT");
                }

                final AutoCompleteTextView text = (AutoCompleteTextView)
                        findViewById(R.id.autoComplete1);

                }

                Collections.sort(list);

                ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>
                        (getApplicationContext(), android.R.layout.simple_spinner_item, list);

                        // TODO Auto-generated method stub
                   //     Toast.makeText(getBaseContext(), list.get(arg2).toString(),

                    }
                });
            } catch (Exception e) {
                Log.e("Fail 3", e.toString());
            }
        }
    }

您想在自动建议中显示颜色吗？在Asynctask中你应该先执行OnPreExecute方法。之后url的所有后台工作都应该在doinbackground方法中。
