title: Android adapter list not working inside thread() for ProgressDialog
body: <p>Below is my code that is not working and i dont understand why it says <strong><em>"Only the original thread that created a view hierarchy can touch its views."</em></strong> when i want to set the adapter for my listview inside LoadValues() method.. <strong><em>"listView.setAdapter(adapter)"</em></strong> </p>
  
  <pre><code>public class ProgressDialogActivity extends Activity {
  
      private ProgressDialog progressDialog;  
      private ListView listView;
      private ArrayList&lt;String&gt; lstValores;
      private Handler progressBarHandler = new Handler();
  
      private int mProgressStatus, mProgressTotal;    
  
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main);              
  
          lstValores = new ArrayList&lt;String&gt;();
          listView = (ListView) findViewById(R.id.listView1);
  
          this.LoadValues();
  
      }//onCreate   
  
  
      public void LoadValues(){
  
          progressDialog = new ProgressDialog(ProgressDialogActivity.this);
          progressDialog.setTitle("Aguarde..");
          progressDialog.setMessage("Cargando lista..");

                      for (int i = 0; i &lt; mProgressTotal; i++) {
  
                          lstValores.add("valor " + i);
  
                          mProgressStatus = (int) ((i * 100) / mProgressTotal);
