스레드가 액세스 할 수 없음보기

Question

나는 listview를 채우는 클래스를 가지고 있지만 스레드가 뷰를 처리 할 수 ​​없다는 오류가 있습니다. 목록을 표시하기 전에 processdialog를 넣는 더 좋은 방법을 알고 있는지 궁금합니다. 감사.

public class MainActivity extends ListActivity { 

// All static variables 
static final String URL = "sample.com"; 
// XML node keys 
static final String KEY_ITEM = "item"; // parent node 
static final String KEY_ID = "id"; 
static final String KEY_NAME = "nome"; 
static final String KEY_END = "endereco"; 
static final String KEY_TEL = "telefone"; 
static final String KEY_BAI = "bairro"; 

private ProgressDialog progressDialog; 
//private Handler handler; 

ListAdapter adapter; 
ListView lv; 

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

    ActionBar actionBar = getActionBar(); 
    actionBar.setTitle("Test"); 
    actionBar.setDisplayHomeAsUpEnabled(true); 
    actionBar.setIcon(R.drawable.icon); 

    //handler = new Handler(); 

    new Thread(){    
     public void run() { 
      runOnUiThread(new Runnable() { 
       @Override 
       public void run() { 
        progressDialog = ProgressDialog.show(MainActivity.this, "", "loading...");      
       } 
      });    
      loadList(); 
      progressDialog.cancel(); 
     } 
    }.start(); 

    lv = getListView();  

    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, 
       int position, long id) { 
      // getting values from selected ListItem 
      String name = ((TextView) view.findViewById(R.id.name)).getText().toString(); 
      String cost = ((TextView) view.findViewById(R.id.cost)).getText().toString(); 
      String description = ((TextView) view.findViewById(R.id.description)).getText().toString(); 

      // Starting new intent 
      Intent in = new Intent(getApplicationContext(), DescriptionActivity.class); 
      in.putExtra("nome", ((TextView) view.findViewById(R.id.name)).getText().toString()); 
      in.putExtra("endereco", ((TextView) view.findViewById(R.id.cost)).getText().toString()); 
      in.putExtra("telefone", ((TextView) view.findViewById(R.id.description)).getText().toString()); 
      startActivity(in); 
     } 
    }); 
} 

public void loadList(){ 

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

    XMLParser parser = new XMLParser(); 
    String xml = parser.getXmlFromUrl(URL); // getting XML 
    Document doc = parser.getDomElement(xml); // getting DOM element 

    NodeList nl = doc.getElementsByTagName(KEY_ITEM); 
    // looping through all item nodes <item> 
    for (int i = 0; i < nl.getLength(); i++) { 
     // creating new HashMap 
     HashMap<String, String> map = new HashMap<String, String>(); 
     Element e = (Element) nl.item(i); 
     // adding each child node to HashMap key => value 
     map.put(KEY_ID, parser.getValue(e, KEY_ID)); 
     map.put(KEY_NAME, parser.getValue(e, KEY_NAME)); 
     map.put(KEY_END, parser.getValue(e, KEY_END)); 
     map.put(KEY_TEL, parser.getValue(e, KEY_TEL)); 
     map.put(KEY_BAI, parser.getValue(e, KEY_BAI)); 

     // adding HashList to ArrayList 
     menuItems.add(map); 
    } 

    // Adding menuItems to ListView 
    adapter = new SimpleAdapter(this, menuItems, 
      R.layout.list_row_lojas, 
      new String[] { KEY_NAME, KEY_END, KEY_TEL, KEY_BAI }, new int[] { 
        R.id.name, R.id.description, R.id.cost, R.id.bairro }); 
    setListAdapter(adapter); 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
    case android.R.id.home: 
     Intent intent = new Intent(this, MainActivity.class); 
     intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     startActivity(intent); 
     return true; 
    default: 
     return super.onOptionsItemSelected(item); 
    } 
} 
}

사용

MainActivity.this.runOnUiThread(new Runnable() { 
       @Override 
       public void run() { 
        progressDialog = ProgressDialog.show(MainActivity.this, "", "loading...");      
       } 
      }); 

대신

runOnUiThread(new Runnable() { 
       @Override 
       public void run() { 
        progressDialog = ProgressDialog.show(MainActivity.this, "", "loading...");      
       } 
      });
