问题 In my Android application, in order to ask the user if he/she wants to resume a current game, I display a dialog saying "Do you want to resume current game? Yes - No" on the main game activity.

问题 I need to show a custom dialog in my Android application. Standard AlertDialog design is unacceptable. Android docs say: Tip: If you want a custom dialog, you can instead display an Activity as a dialog instead of using the Dialog APIs.

问题 I have a DialogFragment , that depending on how it's called, will either pop up a dialog, or start an Intent, based off of results from the dialogFragment . Essentially, my DialogFragment is a list of activities, which depending on how I call I will want more information about the activity, or to start the activity. Ideally, I would like to have something akin to the onActivityResult to handle these results, in my base class. Doing some research has indicated that if I was using a Fragment,

问题 For some reason, a DialogFragment that I've just created won't appear whenever I try to launch it from a click event. Why does the dialog not have a view, when my view has been clearly set builder.setView(rootView) ? Fragment does not have a view click event to launch DialogFragment holder.myButton.setOnClickListener { val dialog = MyDialog() val manager = (holder.itemView.context as FragmentActivity).supportFragmentManager dialog.show(manager, "example") } DialogFragment class MyDialog :

问题 In my Android application I have a multi choice item dialog (similar to that shown in the image) that has a large number of items.

问题 I'm running into a weird issue in my app development. At some point in my app, it would call an Intent (Intent.ACTION_SEND) to launch Gmail, and the "Complete action using..." dialog will appear. Even though I check the default box at the bottom and select Gmail, the next time my app calls for the Intent, the Complete action using dialog keeps appearing.
