I have a UI Lab for Android Programming that I'm trying to complete. I think I'm close, yet so far away. I have four activities that I'm working with but only three of them needed worked on. Here is what I have. I need help with what I'm missing.
Here's the first Activity which is AddToDoActivity

Any thought on how to improve the cancelButton code in the AddToDoAcitivity?

#Override

Everything works until I use updateDisplay method, causing the app to crash

Everything appears correctly on the screen until I fill in updateDisplay() method with code to update my textViews using setText/get.
The app does not crash prior to entering the setText/get code to update from the DarkSky API, but once entered the app crashes and tells me to try again.
I believe everything is entered correctly, but for some reason the app won't take the information. ALSO, I am using the recent version of OkHTTP in cradle, so the issue doesn't lie there. (Permissions are also used)

To get HourOdDay in am/pm you can do something like this:
String format = "hh:mm a"; // your own format
SimpleDateFormat sdf = new SimpleDateFormat(format, Locale.US);
String formated_time = sdf.format(newTime.getTime());
//formated_time would show you time like "hh:mm am/pm".

I would like to add the mechanism that will allow user to insert dates of holidays (this aplication will calculate the salary and holidays means no salary, so it's important).
As I saw here, user SimplyPanda suggested adding an ArrayList<Integer> to do so. However, I wondering how the inserting by user should look like.
Should user know the integer representation of particular dates in Java? - I guess no.
Does anyone have any idea how to implement such functionality?

Anyone please help me from this error, i really want to say thank you to all of u who can resolve this code, Thanks :D

You haven't initialized the txtDate EtidText.
txtDate = (EditText) findViewById(R.id.txtDate);// or what ever you add the id for txtDate
Then you will be fine.

Can anybody help?

li.inflate(R.id.footerView, getListView());
You cannot inflate ids, only layouts.
Replace R.id.footerView with R.layout.your_footer_view_layout.
Also, you probably want to capture the inflated View to some variable to actually use it later.

Try this:
//Inflate footerView for footer_view.xml file
TextView footerView = (TextView) getLayoutInflater().inflate(R.layout.footer_view, null);

You should replace setTag(). Change
priorityView.setTag(toDoItem.getPriority());
to
priorityView.setText(toDoItem.getPriority().ToString());
