Android DialogFragment vs Dialog

由 谁都会走 提交于 2019-11-26 09:28:53
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

I also checked the documentation for the NumberPicker and it said to go check the

How to set DialogFragment&#39;s width and height?

由 自作多情 提交于 2019-11-26 04:58:57
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
