안녕하세요.. 예제보며 공부하고 있는 초보 개발자입니다.
지금 리스트뷰에서 항목을 클릭하면 다음화면으로 넘어가게 할려고합니다.
클릭이벤트문구를 넣으면 실행시키자마자 꺼져버립니다.
아래는 코드입니다.
아 또한 리스트뷰2개가 있는데 2개의 id가 모두 @android:id/list 로 표기되어 있는데 지금상태에서 써도 별 문제가 없는지에 대해서도 궁금합니다!!!!
lv.setOnItemClickListener(
new ListView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(bt1.this, bt1_info.class);
startActivity(intent);
}
});
}public class InboxActivity extends ListActivity {
// Progress Dialog
private ProgressDialog pDialog;
// Creating JSON Parser object
JSONParser jsonParser = new JSONParser();
ArrayList<HashMap<String, String>> inboxList;
// products JSONArray
JSONArray inbox = null;
// Inbox JSON url
private static final String INBOX_URL = "http://ㅍㅍㅍㅍㅍ.php";
// ALL JSON node names
private static final String TAG_MESSAGES = "result";
private static final String TAG_ID = "Title";
private static final String TAG_FROM = "Title";
private static final String TAG_EMAIL = "email";
private static final String TAG_SUBJECT = "Type";
private static final String TAG_DATE = "Date";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.inbox_list);
// Hashmap for ListView
inboxList = new ArrayList<HashMap<String, String>>();
// Loading INBOX in Background Thread
new LoadInbox().execute();
}
/**

class LoadInbox extends AsyncTask<String, String, String> {
/**

@Override

super.onPreExecute();
pDialog = new ProgressDialog(InboxActivity.this);
pDialog.setMessage("Loading Inbox ...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
/**

protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
// getting JSON string from URL
JSONObject json = jsonParser.makeHttpRequest(INBOX_URL, "GET",
params);
// Check your log cat for JSON reponse
Log.d("Inbox JSON: ", json.toString());
try {
inbox = json.getJSONArray(TAG_MESSAGES);
// looping through All messages
for (int i = 0; i < inbox.length(); i++) {
JSONObject c = inbox.getJSONObject(i);
// Storing each json item in variable
String id = c.getString(TAG_ID);
String from = c.getString(TAG_FROM);
String subject = c.getString(TAG_SUBJECT);
String date = c.getString(TAG_DATE);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_ID, id);
map.put(TAG_FROM, from);
map.put(TAG_SUBJECT, subject);
map.put(TAG_DATE, date);
// adding HashList to ArrayList
inboxList.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**

* **/
protected void onPostExecute(String file_url) {
// dismiss the dialog after getting all products
pDialog.dismiss();
// updating UI from Background Thread
runOnUiThread(new Runnable() {
public void run() {
/**
* Updating parsed JSON data into ListView
* */
ListAdapter adapter = new SimpleAdapter(
InboxActivity.this, inboxList,
R.layout.inbox_list_item, new String[] { TAG_FROM, TAG_SUBJECT, TAG_DATE },
new int[] { R.id.from, R.id.subject, R.id.date });
