How to show DialogFragment from Fragment in actionBar android

I use Tabs ActionBar with Fragments. Inside one fragment I have button. I want to show a `DialogFragment` (inside my fragment) when the button is pressed. How can I do that? This is my code ``` public class MainActivity extends FragmentActivity implements EditNameDialogListener { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //showEditDialog(); ActionBar actionbar = getActionBar(); // Tell the ActionBar we want to use Tabs. actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); // initiating both tabs and set text to it. ActionBar.Tab InboxTab = actionbar.newTab().setText("One"); ActionBar.Tab SentTab = actionbar.newTab().setText("Two"); Fragment InboxFragment = new Inbox(); Fragment SentFragment = new SentBox(); InboxTab.setTabListener(new MyTabsListener(InboxFragment)); SentTab.setTabListener(new MyTabsListener(SentFragment)); actionbar.addTab(InboxTab); actionbar.addTab(SentTab); } private void showEditDialog() { FragmentManager fm = getSupportFragmentManager(); EditNameDialog editNameDialog = new EditNameDialog(); editNameDialog.show(fm, "fragment_edit_name"); } @Override public void onFinishEditDialog(String inputText) { Toast.makeText(this, "Hi, " + inputText, Toast.LENGTH_SHORT).show(); } } class MyTabsListener implements ActionBar.TabListener { public Fragment fragment; public MyTabsListener(Fragment fragment) { this.fragment = fragment; } public class Inbox extends Fragment implements EditNameDialogListener{ @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment Utility util = new Utility(getActivity()); View view = inflater.inflate(R.layout.inbox, container, false); ArrayList<String[]> searchResults = util.ReadFile(); final ListView lv1 = (ListView) view.findViewById(R.id.inboxList); lv1.setAdapter(new MyCustomBaseAdapter(getActivity(), searchResults)); lv1.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> a, View v, int position, long id) { Object o = lv1.getItemAtPosition(position); String[] fullObject = (String[])o; Toast.makeText(getActivity(), "You have chosen: " + " " + fullObject[0], Toast.LENGTH_LONG).show(); } }); return view; } @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { // TODO Auto-generated method stub super.onCreateOptionsMenu(menu, inflater); } @Override public boolean onOptionsItemSelected(MenuItem item) { // TODO Auto-generated method stub switch (item.getItemId()) { case R.id.menu_settings: showEditDialog(); break; default: break; } return super.onOptionsItemSelected(item); } private void showEditDialog() { FragmentManager ft = getSupportFragmentManager(); EditNameDialog editNameDialog = new EditNameDialog(); editNameDialog.show(ft, "fragment_edit_name"); } @Override public void onFinishEditDialog(String inputText) { Toast.makeText(getActivity(), "Hi, " + inputText, Toast.LENGTH_SHORT).show(); } } @Override public void onTabReselected(Tab tab, FragmentTransaction ft) { /* * Toast.makeText(StartActivity.appContext, "Reselected!", * Toast.LENGTH_LONG).show(); */ } @Override public void onTabSelected(Tab tab, FragmentTransaction ft) { ft.replace(R.id.fragment_container, fragment); } @Override public void onTabUnselected(Tab tab, FragmentTransaction ft) { ft.remove(fragment); } } public class EditNameDialog extends DialogFragment implements OnEditorActionListener{ public interface EditNameDialogListener { void onFinishEditDialog(String inputText); } private EditText mEditText; public EditNameDialog() { // Empty constructor required for DialogFragment } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_edit_name, container); mEditText = (EditText) view.findViewById(R.id.txt_your_name); getDialog().setTitle("Hello"); // Show soft keyboard automatically mEditText.requestFocus(); getDialog().getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE); mEditText.setOnEditorActionListener(this); return view; } @Override public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { if (EditorInfo.IME_ACTION_DONE == actionId) { // Return input text to activity EditNameDialogListener activity = (EditNameDialogListener) getActivity(); activity.onFinishEditDialog(mEditText.getText().toString()); this.dismiss(); return true; } return false; } public class Inbox extends Fragment implements EditNameDialogListener{ @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment Utility util = new Utility(getActivity()); View view = inflater.inflate(R.layout.inbox, container, false); ArrayList<String[]> searchResults = util.ReadFile(); final ListView lv1 = (ListView) view.findViewById(R.id.inboxList); lv1.setAdapter(new MyCustomBaseAdapter(getActivity(), searchResults));

Toast.makeText(getActivity(), "You have chosen: " + " " + fullObject[0], Toast.LENGTH_LONG).show(); } }); return view; } @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { // TODO Auto-generated method stub super.onCreateOptionsMenu(menu, inflater); } @Override public boolean onOptionsItemSelected(MenuItem item) { // TODO Auto-generated method stub switch (item.getItemId()) { case R.id.menu_settings: showEditDialog(); break; default: break; } return super.onOptionsItemSelected(item); } private void showEditDialog() { FragmentManager ft = getSupportFragmentManager(); EditNameDialog editNameDialog = new EditNameDialog(); editNameDialog.show(ft, "fragment_edit_name"); } @Override public void onFinishEditDialog(String inputText) { Toast.makeText(getActivity(), "Hi, " + inputText, Toast.LENGTH_SHORT).show(); } } ```
