Android - EditText gives IndexOutOfBounds Exception while using textAllCaps

Question

I'm trying to create a very simple registration page using a relative layout. This registration page is linked to a fragment called RegistrationFragment.

I have five EditText fields for this layout: name, phone number, email, password, and confirm password. For some reason, I can enter text into password and confirm password, but whenever I try to enter any text into the other fields, they immediately crash the application with an IndexOutOfBounds Exception.

Here's the full stack trace:

If relevant, I'm "looking" at my Fragment code using the below, which is at the end of the onCreate() method of my main activity for testing purposes. I got the same errors when I tried testing Registration as an activity though.

RegistrationFragment test = new RegistrationFragment(); setContentView(R.layout.fragment_registration);

I had the same problem with textAllCaps for EditText in my application.

I have found that textAllCaps is a property for TextView only. You can not use this property for EditText.

So, I did R&D for it and found a better solution for this issue.

Rather than using textAllCaps we can use android:inputType="textCapCharacters".

E.g.

    <EditText         android:id="@+id/edittext1"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:ems="10"         android:inputType="textCapCharacters"         android:hint="@string/first_name"         android:padding="10dp" >     </EditText> 

If we use android:inputType="textCapCharacters" it will convert all characters into UPPER CASE, like we want in textAllCaps.

P.S. If you use the shift key and type text it may convert the text in lowercase. You can always use toUpper() method in string object to convert it back to uppercase. It may help...

Ok, the problem is that textAllCaps is not working for EditText controls. It only works for commands that are not editable (like TextView). As per documentation on setAllCaps() (which is the code behind version of the textAllCaps):

This setting will be ignored if this field is editable or selectable

So, it will not work.

Now, even I am not sure why your code crashed, it shouldn't have, it should have just be ignored, but maybe, the problem occurs when textAllCaps is set from the xml file... I wasn't sure, but I just suggested what I would have changed the first, and hoped it would work...

Anyhow, I am glad I helped...
