我已经尽我所能找出我的 onItemClickListener 出了什么问题。有一位乐于助人的人试图提供帮助，但他或她说他们绝对没有看到任何问题，并且他们不明白为什么它不起作用。我已经做了很多研究并寻找其他人的代码试图将这些问题联系起来，但它仍然不起作用。我真的需要很多眼睛来帮助我解决这个问题。
列出活动：
public class ListView extends ListActivity {
ArrayList<HashMap<String, String>> questionList;
final String TAG_RESULTS = "results";
final String TAG_QUESTION_SUBJECT = "Subject";
final String TAG_QUESTION_NUMANSWERS = "NumAnswers";
final String TAG_QUESTION = "question";
final String TAG_QUESTION_CONTENT = "Content";
final String TAG_QUESTION_CHOSENANSWER = "ChosenAnswer";
final String TAG_ANSWERS = "Answers";
final String TAG_ANSWER = "Answer";
final String TAG_ANSWERS_CONTENT = "content";
final String TAG_QUERY = "query";
JSONArray question = null;
android.widget.ListView lv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.listview);
questionList = new ArrayList<HashMap<String, String>>();
new LoadAllData().execute();
}
class LoadAllData extends AsyncTask<String, String, String> {
private Dialog pDialog;
@Override
protected void onPreExecute() {
super.onPreExecute();
ProgressDialog pDialog;
pDialog = new ProgressDialog(ListView.this);
pDialog.setMessage("Loading Data. Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
if (pDialog != null && pDialog.isShowing()) pDialog.dismiss();
}
protected String doInBackground(String... args) {
try {
Intent in = getIntent();
String searchTerm = in.getStringExtra("TAG_SEARCH");
String query = URLEncoder.encode(searchTerm, "utf-8");
String URL = "http://example.com";
JSONParsser jParser = new JSONParsser();
JSONObject json = jParser.readJSONFeed(URL);
try {
//question = json.getJSONArray(TAG_QUESTION);
JSONArray questions = json.getJSONObject("all").getJSONArray("questions");
for(int i = 0; i < questions.length(); i++) {
JSONObject question = questions.getJSONObject(i);
String Subject = question.getString(TAG_QUESTION_SUBJECT);
String NumAnswers = question.getString(TAG_QUESTION_NUMANSWERS);
String ChosenAnswer = question.getString(TAG_QUESTION_CHOSENANSWER);
String Content = question.getString(TAG_QUESTION_CONTENT);
//JSONArray Answers = question.getJSONObject(TAG_ANSWERS).getJSONArray(TAG_ANSWER);
//JSONObject Answer = Answers.getJSONObject(0);
//String Content = Answer.getString(TAG_ANSWERS_CONTENT);
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_QUESTION_SUBJECT, Subject);
map.put(TAG_QUESTION_NUMANSWERS, NumAnswers);
questionList.add(map);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return TAG_QUESTION ;
}
@Override
protected void onPostExecute(String file_URL) {
ListAdapter adapter = new SimpleAdapter(getBaseContext(), questionList,
R.layout.listview,
new String[] { TAG_QUESTION_SUBJECT, TAG_QUESTION_NUMANSWERS }, new int[] {
R.id.Subject, R.id.NumAnswers });
setListAdapter(adapter);
}
}
@Override
protected void onListItemClick(android.widget.ListView l, View v, int pos, long id) {
super.onListItemClick(l, v, pos, id);
String Subject = ((TextView) v.findViewById(R.id.Subject)).getText().toString();
String Content = ((TextView) v.findViewById(R.id.Content)).getText().toString();
String ChosenAnswer = ((TextView) v.findViewById(R.id.ChosenAnswer)).getText().toString();
Intent i = new Intent(ListView.this, SingleListItem.class);
i.putExtra("TAG_QUESTION_SUBJECT", Subject);
i.putExtra("TAG_QUESTION_CONTENT", Content);
i.putExtra("TAG_QUESTION_CHOSENANSWER", ChosenAnswer);
startActivity(i);
}
}
问题是我的 onItemClickListener 没有像其他所有问题一样被调用。
