  <p>I also have 2 activities, with 2 listViews, with the same ID of <strong>@android:id/list</strong>.<br>
  When i press <strong>save</strong>, it updates my both listViews.<br>
  How could i edit the code so it updates the desired listView(on certain activity)?</p>
  
  <p><strong>EDIT</strong> This is the main activity, which display the first ListView:  </p>
  
  <pre><code>    @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
      registerForContextMenu(getListView());
      populateAccountList(); // this right here is what i believe is populating the list on the activity
  
      dugme = (ImageButton) findViewById(R.id.btn2);
      dugme.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View view) {
  
  
              Intent myIntent = (new Intent(FullAccountList.this,
                      main2.class).addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION));
  
              startActivity(myIntent);
              overridePendingTransition(0,0);
              finish();
  
  
          }
      });
  
  
  
  }
  
      private void populateAccountList() { // this is the source of it.
      if (getPasswordDatabase() == null) {
          // If the UPM process was restarted since AppEntryActivity was last
          // run then databaseFileToDecrypt won't be set so set it here.
          EnterMasterPassword.databaseFileToDecrypt = Utilities.getDatabaseFile(this);

      } else {
          setListAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, getPasswordDatabase().getAccountNames())); // maybe here i can somehow declare what list to populate?
