從另一個activity/Actionbaractivity打開片段

Question

我想從button actionbaractivity打開片段。 我想打開其他活動的片段。 請幫助

這是我Actionbaractivity：

public class ActionBarParentActivity extends ActionBarActivity { 
    private LinkedHashSet<Integer> enableItems = new LinkedHashSet<Integer>(); 
    private LinkedHashSet<Integer> disableItems = new LinkedHashSet<Integer>(); 
    private Iterator<Integer> iter; 

    public void setEnableItem(LinkedHashSet<Integer> items) { 
     this.enableItems = items; 
    } 

    public void setDisableItem(LinkedHashSet<Integer> items) { 
     this.disableItems = items; 
    } 

    @Override 
    public boolean onPrepareOptionsMenu(Menu menu) { 
     // TODO Auto-generated method stub 
     if (!disableItems.isEmpty()) { 
      iter = disableItems.iterator(); 
      while (iter.hasNext()) { 
       MenuItem item = menu.findItem(iter.next()); 
       item.setVisible(false); 
      } 
     } 

     if (!enableItems.isEmpty()) { 
      iter = enableItems.iterator(); 
      while (iter.hasNext()) { 
       MenuItem item = menu.findItem(iter.next()); 
       item.setVisible(true); 
      } 
     } 
     return super.onPrepareOptionsMenu(menu); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // TODO Auto-generated method stub 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.main_menu, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // TODO Auto-generated method stub 
     switch (item.getItemId()) { 
     case android.R.id.home: 
      // NavUtils.navigateUpTo(this, new Intent(this, 
      // HomeActivity.class)); 
      finish(); 
      break; 

     case R.id.btn_action_upload: 
      if (!Ultils.isConnectingToInternet(this)) { 
       showMsg(getResources().getString(R.string.open_network)); 
       return false; 
      } 
      UserSessionManager userSession = new UserSessionManager(this); 
      if (userSession.getUserSession() != null) { 
       Intent intent = new Intent(this, Maps.class); 
       startActivity(intent); 
      } else { 
       Intent intent = new Intent(this, AuthenticationActivity.class); 
       startActivity(intent); 
      } 
      break; 

     default: 
      break; 
     } 
     return super.onOptionsItemSelected(item); 
    } 

    public void refreshActionBarMenu() { 
     this.supportInvalidateOptionsMenu(); 
    } 

    public void changeActionBarTitle(String title) { 
     getSupportActionBar().setTitle(title); 
    } 

    public void showMsg(String msg) { 
     Toast ts = Toast.makeText(this, msg, 5000); 
     ts.show(); 
    } 

    public void showDialog(String msg) { 
     AlertDialog.Builder buidler = new AlertDialog.Builder(
       ActionBarParentActivity.this); 
     buidler.setMessage(msg); 
     buidler.setPositiveButton(getResources().getString(R.string.ok_label), 
       new DialogInterface.OnClickListener() { 

        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         // TODO Auto-generated method 
         // stub 

        } 
       }); 
     AlertDialog dialog = buidler.create(); 
     dialog.show(); 
    } 

}

我希望這將有助於。

Fragment mFragment = new MainFragment(); 
    FragmentManager fragmentManager = getSupportFragmentManager(); 
      fragmentManager.beginTransaction() 
        .replace(R.id.fragment_xml, fragment).commit();
