Can't insert into Editable

Question

I must be doing something obvious, but I can't figure out what it is. I'm simply trying to insert a character into an Editable:

@Override
public void afterTextChanged(Editable s) {
    Log.d(TAG, "inserting space at " + location);
    s.insert(location, " ");
    Log.d(TAG, "new word: '" + s + "'");
}

But s never changes. The string 's' is long enough, because I print it and it looks good. If I call Editable.clear(), it is cleared, and I can replace multiple characters with Editable.replace(). Ideas?

Answer 1

I found the problem; I set the inputType as "number" and so adding the space silently failed.

Answer 2

To edit an editable with input filters, simply save the current filters, clear them, edit your text, and then restore the filters.

Here is some sample code that worked for me:

@Override
public void afterTextChanged(Editable s) {
    InputFilter[] filters = s.getFilters(); // save filters
    s.setFilters(new InputFilter[] {});     // clear filters
    s.insert(location, " ");                // edit text
    s.setFilters(filters);                  // restore filters
}
