I want to create a simple timepicker dialog in my preferences screen? My question is: Is it possible? Or the timepicker must be in the MainActivity? Can someone explain me how set an alarm in this timepicker dialog and show a Toast when the time setted is reach?
Have you gone through the android guide for
Pickers?
I believe it pretty much explains what you want to do.
You can visit this tutorial as well.

I'm trying to make the datepicker and timepicker show on the main screen textview but I have absolutely no idea how to do it. I did check on the questions section but it didn't help.
Basically now I only have the date and time picker on the main screen with the textview below.
How can I go about doing it? I'm sorry if it sounds to newbie but I really want to do it as I want to help my friend and at the same time learn.

Do you mean actually you have date and time picker, and a textView. Your problem is do not know how to add Listener which can set data to textView after choose date and time.
I need to do a dialog like DatePicker or TimePicker, but the dialogue should display my data. Is this possible, or do I need to do a custom view for this?
Sorry, but I can't comment because I don't have enough rep.
There isn't a ready out of the box dialog that allows custom data to be set. I supposed the best approach would be to create a custom layout with a NumberPicker and then set it as your dialog's view.
This answer should point you to right direction.
Following Android's design guidelines, I ran into this part https://developer.android.com/design/style/metrics-grids.html, where they use a view that I believe is a Spinner in order to show and possibly select the date.
Please guide me in the right directions as I'm not 100% sure this is a Spinner, and also, checking the Calendar app, it seems once you click on it, a DialogFragment pops up, with a single DatePicker (or TimePicker for the hours), but I am not 100% sure of this either.
Thanks in advance
Take a look at the docs, you can specify the Spinner mode. Whether you choose to make it a dialog or dropdown is up to you. Either way, you don't have to worry about setting the value after user has selected it.

I'm creating an app which will have a countdown timer.
I would like to choose the time by TimePicker (after clicking a button).
I would like to have only a few choices. It is 15,30,45 minutes.
Unfortunately TimePicker is not exactly what I wanted.
Is there any possibility to edit TimePicker, to show only a custom set of values?
Thanks in advance!
Rather than showing a TimePicker for choosing 15, 30 or 45 minutes, you should use a Spinner
If you don't know how to use a spinner tell me in the comment!
It is possible to do that using reflection. I am not sure if it is a right thing to do though.
Here's an example of how it could be done. Line 60 replaces the 24-hour spinner with 12 Japanese symbols in android earlier than 3.0. Lines 74-76 do the same for 3.0+.
It might be better to create your own dialog with spinners, but for my code I wanted to mimic the native TimePicker.
HI Every One. I am new to android Developmemt . Actually my project requires to show Timepicker but i doesnot want to show AM or PM option and also not in the header of the picker, There is any way to do this ?
Please reply ASAP
You can remove the AM/PM selector using the setIs24HourView(true) method of TimePicker. I've not tried it myself, but I think this should also remove the AM/PM caption from the header.
Hope that helps, bye
