My first concern is that you are declaring the click handler twice: once in the layout file, and again in code. Use one or the other, but not both.
Second, you need to change btn_details_saveClick() to accept a View parameter. This is what the error message is actually telling you.

Thanks for your reply David
"My first concern is that you are declaring the click handler twice: once in the layout file, and again in code. Use one or the other, but not both."
I thought we have to add the click event on the layout file and add hookup the event to the button also in the initialization of the Activity. i learned, thanks. i am coming from asp.net background
i have changed my function in my frament page to be like this
public void btn_details_saveClick(View view)
{
had
and i ran it and i got the Error
java.lang.IllegalStateException: Could not find a method btn_details_saveClick(View) in the activity class android.support.v7.widget.TintContextWrapper for onClick handler on view class android.support.v7.widget.AppCompatButton with id 'btn_details_save'
i have also have a example project( 9mb) on this link Example Project
To Reproduce the Error
1) Open the drawer
2) Click on loan application and click the button "Continue" and you will get an Error
Thanks

Does the btn_details_saveClick() method belong to the same class that 'owns' the layout?

If you are defining the click-handler in the .xml file, the click-handler must be implemented in the activity not the fragment. If you are defining the click-handler in the .cs file, the click-handler can be implemented in the fragment.
You'll notice in that example that the btn_details_saveClick() method is contained within the activity PersonalDetailsView rather than the fragment PageFragment.

Thank you David i fixed the issue
after making the PersonalDetailsView inherit from Fragment, all started to work.

Good evening
I need to insert notifications in my Android application. This is something similar to RSS service.
Therefore I have inserted NotificationCompat.Builder, and Pendig Intent to this purpose. When user selects corresponding item the application is restarted and updated.
But I have a problem, I don't have idea how to fire the notification. I'm thinking to start something like a Timer, every 15-30 minutes connect to server and look for new event released. If there is one, I'll fire Notification through the corresponded object.
Is this a best prtacice? Is there any better way to do?
I would appreciate any sugestions.
Thanks a lot.

Is the goal for the server itself to notify the app, or for the app to notify itself through the server? If the latter, have you looked at Firebase Cloud Messaging[^]

Thanks a lot.
No is the first one. Server should notify news incoming to the app when we have uploaded new articles in our database. So user should be advise.

Would an RSS solution work for you?

Hello friends,
i was looking for an idea to implement single android xml and java class file as templet ,to minimise the re-usability of same type of class or xml
Example : I have main.xml which will have 5 buttons on screen ,on first button click i have to load the 2nd screen data from configurator file and based on the configuration the view need to change like hiding 3 buttons or 2 buttons 
is it possible to achieve ?

Probably yes, but it depends on what features are available in the code generator you are using. Visual Studio allows you to create your own project templates; not sure about Android studio.

Can you put something at the end of the routine (that plays the music file) to check to see if a button has been clicked? If it has, call that routine again.

What does your code look like to do the moving? What has changed since the time it was working?

Hi, I am trying to build an app where I can play music.For the music play page, what I would like to do is to create a mainActivity that consists of all the codes necessary to play or pause the music track and the Fragment would contain the album art as well as the album details.Any suggestions on how to code this would be greatly appreciated.
