My problem is when the user finish setting his notifications, i cant make it work. The notifications will work based on what he/she choose. I cant seem to find any sources that i could understand easily for this.
i have deleted the codes i tested to make notifications work so that it doesnt look messy. It doesnt work anyway-

Have to decrement one value which is stored using shared preference according to the current date

I have two dates in string format and stored it using shared preference. The first date (current date) is set to date picker date and second one is the date after adding 41 days to the first date. In a button I have to get the difference between the two dates in days and it is stored using shared preference. The problem is, that I have to decrement the difference between these two dates according to each current date. How can do that? Please help.

In your onCheckedChanged() method save the positions in a list. and when button is clicked iterate through the list and delete them from the adapter list.

Datepicker and TimePicker dialogs take two clickes of button

So for the life of me I can not find the reason behind needing to click twice on the start date and start time for the picker dialog to open. I have searched these forums many times and they have all been mostly related to edit text fields whereas mine is a simple button but the onClickListener takes two hits. Thanks in advance.

Hmm, your code looks ok. Can you try adding android:focusable="false" to your buttons. I'm curious if the problem is that you're just requesting focus the first click and the second actually initiates the click.
Also, if this doesn't help, can you put some logs in your click listener and also in the public void showTimePickerDialog(View v) { method as well ... to see if it's triggered the first click at all.

Try to add delay on button click it will avoid multi click
date.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
date.setEnabled(false);
showDatePickerDialog(main);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
date.setEnabled(true);
}
}, 100);
}
});

How do i Get the DatePicker to pop up when TextViewItem is Clicked

I am new to Eclipse and running Juno. I hit the wall developing a mobile app when i was trying to implement a date picker on a text item. I have read similar questions from stackoverflow and applied the answers but it doesn't seem to work for me. I keep making changes and I am totally lost. I tried adding the calender widget but its bigger than the screen so i just want to display a view with the calender for selection instead.
I need my users to be able to select a date for which they wish to travel and when search button is clicked, the entries from the form is used to display a list of available buses they can book. Please find my codes below, No help is too little.
