Editable

public interface Editable
implements CharSequence, GetChars, Spannable, Appendable

android.text.Editable
Known Indirect Subclasses


This is the interface for text whose content and markup can be changed (as opposed to immutable text like Strings). If you make a DynamicLayout of an Editable, the layout will be reflowed as the text is changed.

abstract Editable append(CharSequence text, int start, int end)

Convenience for replace(length(), length(), text, start, end)

abstract Editable append(char text)

Convenience for append(String.valueOf(text)).

abstract void clear()

Convenience for replace(0, length(), "", 0, 0)

abstract void clearSpans()

Removes all spans from the Editable, as if by calling removeSpan(Object) on each of them.

abstract Editable delete(int st, int en)

Convenience for replace(st, en, "", 0, 0)

abstract InputFilter[] getFilters()

Returns the array of input filters that are currently applied to changes to this Editable.

abstract Editable insert(int where, CharSequence text, int start, int end)

Convenience for replace(where, where, text, start, end)

abstract Editable insert(int where, CharSequence text)

Convenience for replace(where, where, text, 0, text.length());

abstract Editable replace(int st, int en, CharSequence source, int start, int end)

Replaces the specified range (st…en) of text in this Editable with a copy of the slice start…end from source.

abstract Editable replace(int st, int en, CharSequence text)

Convenience for replace(st, en, text, 0, text.length())

abstract void setFilters(InputFilter[] filters)

replace

Added in API level 1
Editable replace (int st, 
                int en, 
                CharSequence source, 
                int start, 
                int end)

Replaces the specified range (st…en) of text in this Editable with a copy of the slice start…end from source. The destination slice may be empty, in which case the operation is an insertion, or the source slice may be empty, in which case the operation is a deletion.

Before the change is committed, each filter that was set with setFilters(InputFilter[]) is given the opportunity to modify the source text.

If source is Spanned, the spans from it are preserved into the Editable. Existing spans within the Editable that entirely cover the replaced range are retained, but any that were strictly within the range that was replaced are removed. As a special case, the cursor position is preserved even when the entire range where it is located is replaced.

Parameters
st int
en int
source CharSequence
start int
end int
Returns
Editable a reference to this object.

Parameters
st int
en int
text CharSequence
