InputFilter.AllCaps
extends Object
implements
InputFilter
java.lang.Object | |
↳ | android.text.InputFilter.AllCaps |
This filter will capitalize all the lowercase and titlecase letters that are added through edits. (Note that if there are no lowercase or titlecase letters in the input, the text would not be transformed, even if the result of capitalization of the string is different from the string.)

locale |
Locale : This value cannot be null . |
public CharSequence filter (CharSequence source, int start, int end, Spanned dest, int dstart, int dend)
This method is called when the buffer is going to replace the
range dstart … dend
of dest
with the new text from the range start … end
of source
. Return the CharSequence that you would
like to have placed there instead, including an empty string
if appropriate, or null
to accept the original
replacement. Be careful to not to reject 0-length replacements,
as this is what happens when you delete text. Also beware that
you should not attempt to make any changes to dest
from this method; you may only examine it for context.
Note: If source is an instance of Spanned
or
Spannable
, the span objects in the source should be
copied into the filtered result (i.e. the non-null return value).
TextUtils#copySpansFrom
can be used for convenience if the
span boundary indices would be remaining identical relative to the source.
