I found a thread with this subject from about 6 months ago with no resolution,
so I'll start it up again.
This is an excerpt from the TextView API:
public void addTextChangedListener (TextWatcher watcher)
Since: API Level 1
Adds a TextWatcher to the list of those whose methods are called whenever this
TextView's text changes.
In 1.0, the afterTextChanged(Editable) method was erroneously not called after
setText(char[], int, int) calls. Now, doingsetText(char[], int, int) if there
are any text changed listeners forces the buffer type to Editable if it would
not otherwise be and does call this method.
This seems to make sense for a TextView. Then, when you look at
AutoCompleteTextView, I found that it will display the auto complete view every
time afterTextChanged is called:
private class MyWatcher implements TextWatcher {
public void afterTextChanged(Editable s) {
doAfterTextChanged();
}
public void beforeTextChanged(CharSequence s, int start, int count, int
after) {
doBeforeTextChanged();
}
public void onTextChanged(CharSequence s, int start, int before, int
count) {
}
}
My only choice seems to be to extend AutoCompleteTextView and change the
behavior. I am not able to override "doAfterTextChanged()", nor am I able to
keep it from showing up.
The best solution I can find is to override addTextChangedListener, and ignore
the TextWatcher the AutoCompleteTextView wants to send, and substitute my own
TextWatcher with a more flexible behavior.
Any comments? Is there a much easier solution I've simply missed?
