注册完成后reponse返回的用户名为null

相关代码：

RegisterActivity:
@Override
public void onResponse(User response) {
    stopLoadingProgress();
    Log.e("TAG","用户名："+response.getUserName()+"密码："+response.getPassword());
    Toast.makeText(RegisterActivity.this,"注册成功，用户名："+response.getUserName(),Toast.LENGTH_SHORT).show();
    LoginActivity.launch(RegisterActivity.this,response.getUserName(),response.getPassword());
    finish();
}

LoginActivity:
//从其它页面传递账号、密码到登录页面
public static void launch(Context context, String mUserName, String mPassword) {
    Intent intent = new Intent(context,LoginActivity.class);
    //清除LoginActivity所有的信息
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    intent.putExtra(KEY_USERNAME,mUserName);
    intent.putExtra(KEY_PASSWORD,mPassword);
    context.startActivity(intent);
}

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    initIntent(intent);
}
//获取传递过来账号和密码
private void initIntent(Intent intent) {
    if (intent == null){
        return;
    }
    String username = intent.getStringExtra(KEY_USERNAME);
    String password = intent.getStringExtra(KEY_PASSWORD);
    Log.e("TAG","用户名："+username+"密码："+password);
    if (TextUtils.isEmpty(username) || TextUtils.isEmpty(password)){
        return;
    }
    userName.setText(username);
    userPassword.setText(password);
}

同学，你好！可以在请求注册时把用户名输出一下，是不是请求时传递的就不对呢？祝：学习愉快！
