android-dialogfragment

问题 This should be a simple task, but for some reason I can find a way to set the title of a DialogFragment. (I am setting the dialog contents using onCreateView overload). The default style leaves a place for the title, but I can't find any method on the DialogFragment class to set it. The title is somehow magically set when the onCreateDialog method is used to set the contents, so I wonder if this is by design, or there is a special trick to set it when using the onCreateView overload. 回答1: You

问题 I have some fragments that need to show a regular dialog. On these dialogs the user can choose a yes/no answer, and then the fragment should behave accordingly. Now, the Fragment class doesn't have an onCreateDialog() method to override, so I guess I have to implement the dialogs outside, in the containing Activity . It's ok, but then the Activity needs to report back the chosen answer somehow to the fragment. I could of course use a callback pattern here, so the fragment registers itself at

问题 I'm creating a DialogFragment to show some help messages regarding my app. Everything works fine besides one thing: There is a black stripe at the top of the window that shows the DialogFragment, that I presume is reserved for the title, something I don't want to use. This is specially painful since my custom DialogFragment uses a white background, so the change is way too notorious to be left aside. Let me show you this in a more graphical manner: Now the XML code for my DialogFragment is as

问题 I am using a DialogFragment , which I am showing like this from an Activity : DialogFragmentImage dialog = DialogFragmentImage.newInstance(createBitmap()); dialog.onDismiss(dialog);.onDismiss(this); dialog.show(getFragmentManager(), "DialogFragmentImage"); I would like to check when the DialogFragment was dismissed (for example when the back button was pressed), but in my Activity . How can I do that? How can I "tell" my activity that the DialogFragment has been dismissed? 回答1: Make your

问题 Google recommends that we use DialogFragment instead of a simple Dialog by using Fragments API , but it is absurd to use an isolated DialogFragment for a simple Yes-No confirmation message box. What is the best practice in this case? 回答1: Yes, use DialogFragment and in onCreateDialog you can simply use an AlertDialog builder anyway to create a simple AlertDialog with Yes/No confirmation buttons. Not very much code at all. With regards handling events in your fragment there would be various

问题 What i want: the buttons text is "08:00" now. When click the button it shows a timepicker. The selected time is set to the buttons text. (Alarm app). i have read some tutorials and questions-answers about this, but haven't find the answers yet. After i press the clock button the app crashes.

问题 This is a snippet of code from my project that I am using to learn Android: private void enableLocationSettings() { Intent settingsIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivity(settingsIntent); } @SuppressLint("ValidFragment") public class EnableGpsDialogFragment extends DialogFragment { @Override public Dialog onCreateDialog(Bundle savedInstanceState) { return new AlertDialog.Builder(getActivity()) .setTitle("Tytuł") .setMessage("wiadomosc") .setPositiveButton(

问题 I have a custom alertdialog that implements interfaces so that their callbacks can be invoked. I set breakpoints in the first lines of onDismiss and onShow. The dialog pops up and I see all the views, but the breakpoint in onShow does not get hit and my async task does not get created. public class CountdownDialogFragment extends DialogFragment implements OnClickListener, OnShowListener, OnDismissListener { InnerClassAsyncTask myAsyncTask; @Override public Dialog onCreateDialog(Bundle

问题 Hi I tried using the android supported lib v4 as well as v13 instead of android app lib but eclipse still cannot recognize the getSupportedFragmentManager and getChildFragmentManager functions. Are there any steps I need to take in order fro eclipse to recognize both functions? Currently using Eclipse luna with latest android sdk, targeting api 17 platform. I need either function to see why the app crashes with no view found for id ?? when using viewpager inside dialogfragment. Thanks in

问题 I have a ListView that displays a list of Contacts. When a contact is clicked, a DialogFragment is created which displays a notice on whether or not to Cancel or Confirm. Based on whether they click Cancel or Confirm I want to change the color of the ListView item. How can I get the status of the Button click for the dialog.
