I’m having some difficulty using Autocompletetextview with accented words.
For example:
I’m running names of banking agencies, typing only ita the Itaú bank is finding, as the image below:
However, if I type the last u of the word Itaú without the accent, the autocomplete no longer finds it, as image below:
Is there any way to ignore these accents and find by placing or not the text with accents?
Obs: I’m already doing with custom Adapter, which implements Filterable
Below is the code of the custom Adapter:
public class HRArrayAdapter<T> extends BaseAdapter implements Filterable {
private List<T> mObjects;
private final Object mLock = new Object();
private int mResource;

See if it helps: Is there a way to get Rid of Accents and Convert a Whole string to regular Letters?

Thanks Math! Sorry for the delay in answering, but it helped me yes! Just use the java.text.Normalizer
