자동완성 기능에 관해서~

Question

public class Search_By extends Activity {

AutoCompleteTextView search;
Button goSearch_Button;
private ArrayAdapter<String> autoCompAdapter;


Context context;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search);

autoCompAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line);
autoCompAdapter.setNotifyOnChange(true);

search= (AutoCompleteTextView)findViewById(R.id.serch);
search.setThreshold(2);

search.addTextChangedListener(textChecker);
search.setAdapter(autoCompAdapter);



goSearch_Button = (Button)findViewById(R.id.searchbutton);

goSearch_Button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {

Intent intent = new Intent(this, Search_list.class);

intent.putExtra("name",search.getText().toString());
startActivity(intent);
}
});
}

final TextWatcher textChecker = new TextWatcher() {

@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
Log.d("onTextChanged","1");
//autoCompAdapter.clear();
HttpGetTask httpGetTask = new HttpGetTask();
httpGetTask.execute();
}

@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub

}

@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub

}
};

private void callPHP(){
Log.d("callPHP","callPHP");
String result ="";
InputStream is =null;

try{
ArrayList<NameValuePair> nameValPairs = new ArrayList<NameValuePair>();
nameValPairs.add(new BasicNameValuePair("hotel_name", search_hotel.getText().toString()));

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://test.com/text/json.php"
+"?flag=6"+"&"+"hotel_name="+hotel_name);
httppost.setEntity(new UrlEncodedFormEntity(nameValPairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();


}catch(UnsupportedEncodingException e) {
e.printStackTrace();
}catch(ClientProtocolException e) {
e.printStackTrace();
}catch(IOException e) {
e.printStackTrace();
}catch(Exception e){
e.printStackTrace();
Log.e("Log_TAG","Error in http connection " + e.toString());
}

try{

}
is.close();

}

try{

for(int i=0;i<jArray.length();i++){
JSONObject json_data = jArray.getJSONObject(i);
Log.d("json_data",json_data.getString("name"));
autoCompAdapter.add(json_data.getString("name"));
}
}catch(JSONException e){
Log.e("Log_TAG","Error parsing data"+e.toString());
}
}

public class HttpGetTask extends AsyncTask<Void, Void, String> {
String url = "";

public HttpGetTask() {
super();
}

public HttpGetTask(String latitude, String longitude) {
super();
}

public HotelInfomastion_Get_Seters data;

protected String doInBackground(Void... Void) {
String result = "";

callPHP();
return result;
}

protected void onPreExecute(){

}

protected void onPostExecute(String response) {
}

}

}

위에가 소스 코드구요~ 제가 하고싶은건

 

autocompleteTextView에 안드로이드 라고 치면 칠때마다 json.php에 치고 있는 글자를 날려

자동완성기능을 보여주고싶은데요

 

일단 칠때마다 json으로 잘읽어 오고 있다는건

 

Log.d("json_data",json_data.getString("name"));를 통해서 알겠는데요

 

여기까진 다 잘되는데

 

자동완성 목록이 뜨질않네요 ...불러오는건 되는데 목록이 뜨질 않아서, 뭐가 문제인지 잘모르겠네요.

 

선배님들 조언 잘부탁드리겠습니다 .ㅠ
