abstract member AddTextChangedListener : Android.Text.ITextWatcher -> unit
override this.AddTextChangedListener : Android.Text.ITextWatcher -> unit
Parameters
- watcher
- ITextWatcher
- Attributes
Remarks
Adds a TextWatcher to the list of those whose methods are called whenever this TextView's text changes.
In 1.0, the TextWatcher#afterTextChanged
method was erroneously not called after #setText
calls. Now, doing #setText
if there are any text changed listeners forces the buffer type to Editable if it would not otherwise be and does call this method.
