如何将EditText中的每个单词大写？

import android.text.Editable;
import android.text.TextWatcher;
import android.widget.EditText;

public class EditTextUtils {
    public static void capitalizeWords(final EditText editText) {
        editText.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
                
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                
            }

            @Override
            public void afterTextChanged(Editable s) {
                String text = s.toString();
                String[] words = text.split("\\s+"); // 使用空白字符分割单词

                StringBuilder result = new StringBuilder();
                for (String word : words) {
                    if (!word.isEmpty()) {
                        String capitalizedWord = word.toUpperCase();
                        result.append(capitalizedWord).append(" ");
                    }
                }

                // 移除最后一个空格
                if (result.length() > 0) {
                    result.deleteCharAt(result.length() - 1);
                }

                // 设置转换后的文本回EditText中
                editText.removeTextChangedListener(this);
                editText.setText(result.toString());
                editText.setSelection(result.length());
                editText.addTextChangedListener(this);
            }
        });
    }
}

EditText editText = findViewById(R.id.editText);
EditTextUtils.capitalizeWords(editText);
