ERREUR: android.view.ViewRootImpl $ CalledFromWrongThreadException: Seul le thread d'origine qui a créé une hiérarchie de vues peut toucher ses vues

Question

Je reçois des résultats du serveur lorsque l'utilisateur tape sa requête. Initialement, je tirais une requête sur chaque personnage entré. Maintenant, j'ai mis un délai de 500 ms après que l'utilisateur tape dans son dernier caractère & puis je tire la requête pour récupérer les résultats du serveur. Je reçois l'erreur indiqué dans la question sur la ligne suivante, à l'intérieur onSuccess():

search_listview.setAdapter(searchAdaptor); 

Voici mon code:

@Override 
public void afterTextChanged(Editable s) { 
if(!s.equals("")&&s.length()!=0){ 
     TextView tv_emptyView = (TextView)findViewById(R.id.tv_emptyView); 
     tv_emptyView.setVisibility(View.GONE); 
     if(frndList!=null&&frndList.size()!=0) 
     frndList.removeAll(frndList); 
     if(searchAdaptor!=null){ 
      searchAdaptor.notifyDataSetChanged(); 
     } 
     search_listview.setVisibility(View.VISIBLE); 
     pageNumber=0; 

    timer.cancel(); 
    timer = new Timer(); 
    timer.schedule(
      new TimerTask() { 
       @Override 
       public void run() { 
        getListbyName(++pageNumber); 
       } 
      }, 
      DELAY 
    ); 
}else if(s.equals("")||s.length()==0){ 
     TextView tv_emptyView = (TextView)findViewById(R.id.tv_emptyView); 
     tv_emptyView.setVisibility(View.VISIBLE); 
     search_listview.setVisibility(View.GONE); 
    } 

} 

private void getListbyName(int page) { 
    GlobalSearchRequestHandler globalSearchRequest = new GlobalSearchRequestHandler(
      this, this, UserInfoSettings.INSTANCE.getUserId(), 
      editTextSearch.getText().toString(), page + "", true,progressBar); 
    globalSearchRequest.execute(); 
} 
@Override 
public void onSuccess(Object response) { 

    if (response instanceof GlobalSearchBean) { 
     GlobalSearchBean advSearchResultbean = (GlobalSearchBean) response; 
     if (advSearchResultbean.getErrorCode().equalsIgnoreCase("000")) { 
      frndList = advSearchResultbean.getUserList(); 
       if (frndList != null && frndList.size() > 0) { 
       loading = true; 
       if(searchAdaptor!=null&& pageNumber!=1){ 
        searchAdaptor.updateFriendList(frndList); 
       }else{ 
        searchAdaptor = new SmartEntourageSearchAdaptor(this, AdvanceSearchScreenActivity.this, frndList, true); 
        search_listview.setAdapter(searchAdaptor); 
        searchAdaptor.notifyDataSetChanged(); 
       } 
      } else{ 
       if (searchAdaptor != null && pageNumber != 1) { 
        loading = true; 
        searchAdaptor.updateFriendList(frndList); 
       } else { 
        TextView tv_emptyView = (TextView) findViewById(R.id.tv_emptyView); 
        tv_emptyView.setVisibility(View.VISIBLE); 
        search_listview.setVisibility(View.GONE); 
       } 
      } 
     } 
    } 
} 

Je suis allé par & essayé réponses sur stackoverflow mais ne fonctionne pas.

Remplacer ceci:

timer.cancel(); 
timer = new Timer(); 
timer.schedule(
     new TimerTask() { 
      @Override 
      public void run() { 
       getListbyName(++pageNumber); 
      } 
     }, 
     DELAY 
); 

Avec ceci:

search_listview.postDelayed(new Runnable() { 
    @Override 
    public void run() { 
     getListbyName(++pageNumber); 
    } 
}, DELAY);
