The DialogFragment has the same lifecycle and callback methods as any other Fragment. Just with conventional fragments, you can pass data to the dialog packaged as arguments, using the same patterns. You can use a factory method, typically named newInstance(), to pass the data as Java objects, and then you can break up the object into values that can stored in the arguments bundle.
- [Narrator] Once you've wrapped a dialogue…inside a dialogue fragment, you can then…treat it like any other fragment.…To send it default data, pass in arguments,…and to get data out, create interfaces…and call back methods.…In this exercise, I'll show you how to pass data in.…In this version of the application,…named dialogue arguments, I've added code…to get references to a set of edit…text components in the dialogue's layout.…There are three, named ET first name,…ET last name, and ET age.…
Those three edit text components match this class's fields,…which has two strings, and one integer.…Just like in a previous video, I've…implemented the parcelable interface in this class.…This will allow me to take an object that's…an instance of this class, and pass it around…as an argument in a fragment.…I'll go back to the data entry dialog class,…and I'll add a new instance method.…This is a factory method.…I'll allow it to receive a single argument,…an instance of that person class.…
Now, because that class is parcelable,…
