Answer 1

You can get hour of the day using this:

int hour = Calendar.getInstance().get(Calendar.HOUR_OF_DAY);

HOUR_OF_DAY will give you 24-hour time. Then just check something like this:

if (hour >= 22 && hour <= 9) button.setEnabled(false);

Now there are few options to disable the button. You can use:

• setClickable(false)
• setEnabled(false)
• setOnClickListener(null)

Notice that if you setOnClickListener(null) then you need to set your listener again if the time is correct.
