/ 18 октября 2018

Я добавил TextChangedListener к одному EditText в моем приложении.При тестировании приложения на телефоне LG (LG G5, Android 6) или эмуляторе TextChangedListener работает как положено.Тем не менее, телефон Samsung (Samsung Galaxy S7, Android 8) вызывает предупреждения в моем журнале:

Это затрудняет набор текста, и всякий раз, когда я хочу удалить все символы, удерживая нажатой кнопку назад, только одинперсонаж удаляется.

В чем проблема и как я могу ее решить?

Вот мой TextWatcher: 

public class AmountTextWatcher implements TextWatcher {

    private Context context;
    private EditText editText;
    private TextView textView;
    private String SUFFIX;
    private String prevText;


    public AmountTextWatcher(Context context, EditText editText, TextView textView) {
        this.context = context;
        this.editText = editText;
        this.textView = textView;
        this.SUFFIX = context.getResources().getString(R.string.usd);
        prevText = "";
    }


    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        prevText = s.toString();
    }

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

    @Override
    public void afterTextChanged(Editable s) {
        editText.removeTextChangedListener(this);

        int iniLength;
        int endLength;

        iniLength = editText.getText().toString().length();
        String onlyDigits = s.toString().replaceAll("\\D+", "");
        String onlyDigitsPrevText = prevText.replaceAll("\\D+", "");

        boolean suffixChange = false;
        if (iniLength != 1) {
            suffixChange = !editText.getText().toString().substring(iniLength - SUFFIX.length() - 1).equals(" " + SUFFIX);//|| when user tries to type number between or after suffix characters
        }

        long amount = onlyDigits.isEmpty() ? 0 : Long.parseLong(onlyDigits);

        if (textView != null) {
            String paymentAmount = String.format("%s USD", displayFormat(amount));//actual actions is more different, this is just example

            textView.setText(paymentAmount);
        }

        String formattedString;
        int newCursorPos;

        if (onlyDigits.isEmpty()) {//when user deletes all the text
            formattedString = "";
            newCursorPos = 0;
        } else {
            formattedString = displayFormat(amount) + " " + SUFFIX;
            endLength = formattedString.length();
            int sel = editText.getSelectionStart();

            if (onlyDigits.equals(onlyDigitsPrevText) || iniLength == 1 || suffixChange) {//when user tries to delete blank spaces or suffix || when user types for the first time
                newCursorPos = formattedString.length() - SUFFIX.length() - 1;
            } else {
                newCursorPos = sel + endLength - iniLength;
            }
        }

        editText.setText(formattedString);
        editText.setSelection(newCursorPos < 0 ? 0 : newCursorPos);

        editText.addTextChangedListener(this);
    }

    private static String displayFormat(double src) {
        DecimalFormatSymbols otherSymbols = new DecimalFormatSymbols();
        otherSymbols.setDecimalSeparator('.');
        otherSymbols.setGroupingSeparator(' ');
        DecimalFormat decimalFormat = new DecimalFormat("#,###.##", otherSymbols);

        return decimalFormat.format(src);
    }
}
