setOnClickListener ne répond pas

Question

J'ai trouvé ma réponse dans mon post récent mais maintenant quelque chose gagne en focus de ma liste, donc quand j'essaie de cliquer sur un élément de la liste que je veux sélectionner, rien ne se passe. J'avais fait quelques recherches et appris que quelque chose met l'accent sur l'activité quand cela se produit et la seule chose à laquelle je peux penser est que c'est ma scollview. J'ai essayé de mettre android:focusable="false"> dans mon fichier xml sous mon scrollview mais j'ai toujours les mêmes résultats. Donc, je suis juste en espérant que quelqu'un peut me donner quelques conseils

ListActivity:

public class List extends ListActivity {  


    ArrayList<HashMap<String, String>> questionList;   

    final String TAG_RESULTS = "results"; 
    static 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;   

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     //setContentView(R.layout.listview);   

     questionList = new ArrayList<HashMap<String, String>>(); 

     new LoadAllData().execute(); 
     } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 

     if (resultCode == 100) { 
      Intent intent = getIntent(); 
      startActivity(intent); 
      finish(); 
     } 
    } 

    class LoadAllData extends AsyncTask<String, String, String> { 


     @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://answers.yahooapis.com/AnswersService/V1/questionSearch?appid=4vCW8F3V34GzdMlXOS.yc2WfF5DCnCgqhK0nwCJmEFDgRwEbIgnAoEgJ0zynqOAWtQ&query="+ query +"&search_in=question&sort=relevance&results=25&output=json"; 
       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);

        //JSONObject Answer = Answers.getJSONObject(0); 

        //String Content = Answer.getString(TAG_ANSWERS_CONTENT); 

           HashMap<String, String> map = new HashMap<String, String>();

           map.put(TAG_QUESTION_NUMANSWERS, NumAnswers); 

           questionList.add(map); 


        }

Essayez de déplacer votre listener en dehors de la AsyncTask. Faites-en une variable membre et initialiser dans onCreate()

public class List extends ListActivity {  

ListView lv; 
ArrayList<HashMap<String, String>> questionList;   

...  

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    //setContentView(R.layout.listview);   

    questionList = new ArrayList<HashMap<String, String>>(); 
    lv = getListView(); 
    lv.setOnItemClickListener(new OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, 
      int position, long id) {      

      String Subject = ((TextView) findViewById(R.id.Subject)).getText().toString(); 
      String Content = ((TextView) findViewById(R.id.Content)).getText().toString(); 
      String ChosenAnswer = ((TextView) 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); 
      } 

    });  

    new LoadAllData().execute(); 

Votre AscncTask termine donc votre listener est probablement pas plus là. Vous pouvez toujours régler votre Adapter il suffit de déplacer le onItemClick() et l'initialisation.

Depuis sa ListActivity vous n'avez pas besoin de mettre l'auditeur sur elle. Implémentez simplement la méthode

public void onListItemClick(ListView l, View v, int position, long id) 
{ 
    // do your work 
}
