如何从AlertDialog返回到AlertDialog之前

Question

How can I return from an AlertDialog which is called and offers more buttons and the user clicks on one of this buttons, then a new AlertDialog pops up with an input field. So if I check if the user input is eg numeric, how can I return to the AlertDialog offered before?

Answer 1

I'd suggest using a DialogFragment from the support library for each of these Dialogs. Just add onClickListeners to each of the buttons of the first DialogFragment and show the second DialogFragment in onClick .

There should not be any necessity for checking if the input is a number if you just set the appropriate input type first.

When the user taps a button on the second DialogFragment , just call dismiss() .
