Summary
In this chapter, we have seen and implemented a common UI design with dialog windows using the DialogFragment
class.
We went a step further when we started the Note to self app by implementing more complicated dialogs that can capture information from the user. We saw that DialogFragment
enables us to have any UI we like in a dialog box.
In the next chapter, we will begin to deal with the obvious problem whereby the user can only have one note, by exploring Kotlin's data handling classes.
