I am trying to do some validation of an editText field, allow me to elaborate because I am using a bunch of concepts that all have their own questions in stackOverflow but I have the feeling that what I'm trying to do is not yet answered in any of them, and this is something rather basic so either I'm screwing up badly or I just found a bug, also, many of the popular questions and answers are a couple of years old...
I have two Edittext fields which contain an initial date and a termination date which are input from a datepicker, I am validating that after the termination date has been input by the datepicker this date happens after the initial date, and that if it doesn't it displays an error using setError.
So far so good, I manage to do all that but there is something bothering me:
When I first click on the EditText it does nothing (because I use setInputType(InputType.TYPE_NULL) along with android:focusableInTouchMode="true" in the XML; to avoid showing me the keyboard, so it clicks, get selected, and no keyboard, but also no datepicker, until you click again, then the onClick method triggers the datepicker and all works as intended.)
I was going to show you images but I don't have the rep points :/
If I use setFocusable(false), something weird happens, when the setError comes up only the icon shows without the text.
If I don't use setFocusable(false), the editText appears as selected when the activity starts (no cursor flashing because I disabled input) and stays selected (it stays blue but you can click anywhere)
If I don't want it to be selected at start I use android:focusableInTouchMode="true" in the XML in the parent layout, per recommendation of this question (Stop EditText from gaining focus at Activity startup) and that solves that problem. But I have the first click and nothing happens second click and shows the datepicker problem again... what am I doing wrong.
