私はタブでActionBar with Fragmentsを使用します。 1つの断片の中にボタンがあります。ボタンを押したときにDialogFragment（私の断片の中に）を表示したい。どうやってやるの？actionBarのフラグメントからDialogFragmentを表示するにはアンドロイド
これは私のコード
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());

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;

ありますgetSupportFragmentManager（）のエラー –
DialogFragmentのインポートを確認してください、それはサポートライブラリ –
からである必要がありますそれからです:( –
