代码：

LinearLayout Elementslist = (LinearLayout) findViewById(R.id.view);
                    // LIST
                    for (int i = 0; i < form.getElementsArray().size(); i++) {
                        LayoutInflater inflator = (FormActivity.this)
                                .getLayoutInflater();
                        View convertView = inflator.inflate(R.layout.form_row,
                                null);

                        final RElement ele = form.getElementsArray().get(i);

                        TextView desc = (TextView) convertView
                                .findViewById(R.id.desc);
                        final EditText edit = (EditText) convertView
                                .findViewById(R.id.edit);

                        desc.setText(ele.getDescription());

                        edit.setError(getResources().getString(
                                R.string.required));

                        final int pos = i;

                        edit.addTextChangedListener(new TextWatcher() {

                            public void afterTextChanged(Editable s) {
                                if (ele.getRegularExpression().equals("")) {
                                    if (isValid(edit,
                                            ele.getRegularExpression(),
                                            ele.getDescription(), false)) {
                                        ele.setValue(edit.getText().toString());
                                        form.getReadies().set(pos, true);
                                    } else
                                        form.getReadies().set(pos, false);
                                } else {
                                    if (isValid(edit,
                                            ele.getRegularExpression(),
                                            ele.getDescription(), true)) {
                                        ele.setValue(edit.getText().toString());
                                        form.getReadies().set(pos, true);
                                    } else
                                        form.getReadies().set(pos, false);
                                }
                            }

                            public void beforeTextChanged(CharSequence s,
                                    int start, int count, int after) {
                            }

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

                        });

                        Elementslist.addView(convertView);
                    }

但它指向了这个：

   public static boolean isValid(EditText editText, String regex,
        String errMsg, boolean required) {
    String text = editText.getText().toString().trim();
    editText.setError(null);
    if (required && !(editText.getText().length() != 0)) {
        editText.setError(res.getString(R.string.empty));
        return false;
    }
    if (required && !Pattern.matches(regex, text)) {
        editText.setError(res.getString(R.string.invalid));
        return false;
    }
    return true;
}

我发现我的代码运行良好，服务器上使用的正则表达式是一个问题。
