AlertDialog binding
Sometimes we want to show an AlertDialog, but the title or the message of that dialog depends on a Field.
In this case we can use a FieldAlertDialogBuilder. This class extends AlertDialog.Builder from the AndroidX library, but provides the methods setTitle and setMessage that accept a Field of Charsequence and will respectively change the title or the message of the dialog as soon as the Field changes.
For example:
FieldAlertDialogBuilder()
.setTitle(movie.name)
.setMessage(movie.name.transform { name->
"Set $name as watched?"
})
.setPositiveButton(...)
.setNeutralButton(...)
.show()
new FieldAlertDialogBuilder()
.setTitle(movie.getName())
.setMessage(movie.getName().transform(name->
"Set " + name + " as watched?"
))
.setPositiveButton(...)
.setNeutralButton(...)
.show();
