InputFilter.AllCaps

public static class 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.)

Summary

Public constructors

InputFilter.AllCaps()
InputFilter.AllCaps(Locale locale)

Constructs a locale-specific AllCaps filter, to make sure capitalization rules of that locale are used for transforming the sequence.

Public methods

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.

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). copySpansFrom(Spanned, int, int, Class, Spannable, int) can be used for convenience if the span boundary indices would be remaining identical relative to the source.

Parameters
source CharSequence

start int

end int

dest Spanned

dstart int

dend int

Returns
CharSequence
