使用此代码时，出现以下错误：

构造函数ArrayAdapter（new AdapterView.OnItemSelectedListener（）{}，int，String
[]）未定义

谁能帮助纠正这一点？谢谢

private void setDynamicSpinnerBE() {
    beSpinner = (Spinner) findViewById(R.id.spBE);
    final String[] itemsSpinner2;
    lensSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        public void onItemSelected(AdapterView<?> parent, View view,
                int position, long id) {
            Integer focalLength = (Integer) parent.getAdapter().getItem(
                    position);
            itemsSpinner2 = getBellowsExtension(focalLength, maxBellows,
                    precision);

            ArrayAdapter<CharSequence> beAdapter = new ArrayAdapter<CharSequence>(
                    this, android.R.layout.simple_spinner_item,
                    itemsSpinner2);
            beAdapter
                    .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            beSpinner.setAdapter(beAdapter);

        }

        public void onNothingSelected(AdapterView<?> parent) {
            beSpinner.setAdapter(null);
        }
    }

    );
    ...
}
