Попробуйте использовать собственный класс, который будет расширяться от DialogFragment
Например:
public class QuestionDialogFragment extends DialogFragment
{
public final static String BF_TITLE = "QuestionDialogFragment.BF_TITLE";
public final static String BF_QUESTION = "QuestionDialogFragment.BF_QUESTION";
private Callback mCallback;
public static void init(FragmentManager fragmentManager, String title, String question, Callback callback)
{
Bundle bundle = new Bundle();
bundle.putString(BF_TITLE, title);
bundle.putString(BF_QUESTION, question);
QuestionDialogFragment dialog = new QuestionDialogFragment();
dialog.setCallbackListener(callback);
dialog.setArguments(bundle);
dialog.show(fragmentManager, null);
}
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setCancelable(false);
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
Bundle bundle = getArguments();
String title = null;
String question = null;
if (bundle != null)
{
if (bundle.containsKey(BF_TITLE))
{
title = bundle.getString(BF_TITLE);
}
if (bundle.containsKey(BF_QUESTION))
{
question = bundle.getString(BF_QUESTION);
}
}
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(getActivity());
alertDialogBuilder.setTitle(title);
alertDialogBuilder.setMessage(question);
//null should be your on click listener
alertDialogBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
mCallback.success();
dialog.dismiss();
}
});
alertDialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
mCallback.cancel();
dialog.cancel();
}
});
return alertDialogBuilder.create();
}
public void setCallbackListener(Callback callback)
{
this.mCallback = callback;
}
public static interface Callback
{
void success();
void cancel();
}
}
И используйте его где угодно в вашем коде:
QuestionDialogFragment.init(
getFragmentManager(),
"Some title",
"Some question?",
new QuestionDialogFragment.Callback()
{
@Override
public void success()
{
// @TODO if user choice YES;
}
@Override
public void cancel()
{
// @TODO if user choice CANCEL;
}
});
Если вы хотите создать собственное представление вместо стандартного диалогового окна, просто вместо:
Dialog onCreateDialog(Bundle savedInstanceState)
использовать
View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
Например:
нужно создать значения / layout / your_fragment_layout.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/kom_purchase_dialog_root_view">
<TextView
android:id="@+id/kom_purchase_dialog_message_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="some text"/>
<LinearLayout
android:layout_gravity="bottom"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="@+id/kom_purchase_dialog_negative_button"
android:layout_alignParentBottom="true"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Cancel"/>
<Button
android:id="@+id/kom_purchase_dialog_positive_button"
android:layout_toRightOf="@+id/kom_purchase_dialog_negative_button"
android:layout_alignParentBottom="true"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Ok"/>
</LinearLayout>
</FrameLayout>
и для этого макета измените собственный класс на:
public class QuestionDialogFragment2 extends DialogFragment
{
public final static String BF_TITLE = "QuestionDialogFragment.BF_TITLE";
public final static String BF_QUESTION = "QuestionDialogFragment.BF_QUESTION";
private Callback mCallback;
public static void init(FragmentManager fragmentManager, String title, String question, Callback callback)
{
Bundle bundle = new Bundle();
bundle.putString(BF_TITLE, title);
bundle.putString(BF_QUESTION, question);
QuestionDialogFragment2 dialog = new QuestionDialogFragment2();
dialog.setCallbackListener(callback);
dialog.setArguments(bundle);
dialog.show(fragmentManager, null);
}
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setCancelable(false);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
Bundle bundle = getArguments();
String title = null;
String question = null;
if (bundle != null)
{
if (bundle.containsKey(BF_TITLE))
{
title = bundle.getString(BF_TITLE);
}
if (bundle.containsKey(BF_QUESTION))
{
question = bundle.getString(BF_QUESTION);
}
}
View view = super.onCreateView(inflater, container, savedInstanceState);
if (view == null)
{
view = inflater.inflate(R.layout.your_fragment_layout, null, false);
view.setTag(new Holder(view));
}
Holder holder = (Holder) view.getTag();
holder.messageTextView.setText(question);
holder.positiveButton.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
mCallback.success();
}
});
holder.negativeButton.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
mCallback.cancel();
}
});
return view;
}
public void setCallbackListener(Callback callback)
{
this.mCallback = callback;
}
public static interface Callback
{
void success();
void cancel();
}
private final class Holder
{
public TextView messageTextView;
public Button positiveButton;
public Button negativeButton;
private Holder(View view)
{
messageTextView = (TextView) view.findViewById(R.id.question_dialogfragment_message_textview);
positiveButton = (Button) view.findViewById(R.id.question_dialogfragment_positive_button);
negativeButton = (Button) view.findViewById(R.id.question_dialogfragment_negative_button);
}
}
}
и то же использование:
QuestionDialogFragment2.init(
getFragmentManager(),
"Some title",
"Some question?",
new QuestionDialogFragment2.Callback()
{
@Override
public void success()
{
// @TODO if user choice YES;
}
@Override
public void cancel()
{
// @TODO if user choice CANCEL;
}
});
Для обоих подходов будет работать void onSaveInstanceState (Bundle outState) и сохранять состояние после поворота. Я думаю, что лучше и универсальнее, чем использовать простой диалог.
