解决： 处理物理返回按钮的回传参数，不要在onBack函数中回传参数。

@Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {

        if (keyCode == KeyEvent.KEYCODE_BACK) {
            Intent intent = new Intent();
            intent.putExtra("position", position);
            intent.putExtra("isCollection", isCollection);
            setResult(RESULT_OK, intent);
        }
        return super.onKeyDown(keyCode, event);
    }
