Datepicker and TimePicker dialogs take two clickes of button

Datepicker and TimePicker dialogs take two clickes of button - android

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.
This is my Class:

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 to retrieve data from the firebase and show inside the CardView nicely

I have created the CreateEvent.java module to upload the data to firebase. But how to retrieve the data and show in the Cardlist? For example show in the xml file below. And also if there was more than 1 data in firebase, how to show in with multiple cardlist that I have created in the xml file?

Can anyone help please? When click on the quiz button the application will close. I want it to go to quiz page which called HomeScreen.java

looks good to me, did u declare the second activity in the manifest file? :
<activity android:name="HomeScreen"/>
If that doesn't work, use some break points and the debugger, hope it helps.

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.
