DialogFragment with clear background (not dimmed)

阅读更多关于 DialogFragment with clear background (not dimmed)

问题 I\'m trying to get the background of a DialogFragment to be completely clear. With setting the style item android:windowIsFloating to true (the default), the DialogFragment displays exactly how I want it to, but has a very dimmed background. By setting android:windowIsFloating to false, I get the clear background I want, but the DialogFragment blows up to about 95% of the screen, leaving only a tiny gap around it where you can see through to the view it overlays. I\'ve tried ton\'s of tweaks

问题 I have been having this problem in an application I am building. Please ignore all of the design shortcomings and lack of best practice approaches, this is purely to show an example of what I cannot solve.

Question: How does one create a callback from a DialogFragment to another Fragment. In my case, the Activity involved should be completely unaware of the DialogFragment. Consider I have public class MyFragment extends Fragment implements OnClickListener Then at some point I could do DialogFragment dialogFrag = MyDialogFragment.newInstance(this); dialogFrag.show(getFragmentManager, null); Where MyDialogFragment looks like protected OnClickListener listener; public static DialogFragment newInstance(OnClickListener listener) { DialogFragment fragment = new DialogFragment(); fragment.listener =

Android DialogFragment vs Dialog

阅读更多关于 Android DialogFragment vs Dialog

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? PJL 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 ways of doing it but I simply define a message Handler in my Fragment , pass it into the DialogFragment

阅读更多关于 How to set DialogFragment's width and height?

问题 I specify the layout of my DialogFragment in an xml layout file (let\'s call it layout_mydialogfragment.xml ), and its layout_width and layout_height attributes particularly (to be 100dp each let\'s say). I then inflate this layout in my DialogFragment\'s onCreateView(...) method as follows: View view = inflater.inflate(R.layout.layout_mydialogfragment, container, false); Unfortunately, I find that when my dialog (DialogFragment) appears, it does not respect the layout_width and layout_height
