在我的Android应用中，我有3项活动供用户填写个人资料并注册：
我能够传递ParseUser对象并将用户的输入保存在Parse的第1个活动和第2个活动中。但是，在第3次活动中，我无法在Parse上保存Pin编号和密码。我使用Log.d来检查userID，它对所有3个活动都是一样的，Pins和密码字段都有值。我只是不明白为什么我不能使用ParseUser对象的saveInBackground来保存最后一个活动中的Pins和密码。我想知道是否有专家可以帮助我。非常感谢你。
第一次注册活动： 公共类RegisterActivity扩展了Activity {
protected EditText mFirstName;
protected EditText mMiddleName;
protected EditText mLastName;
protected EditText mUserEmail;
protected EditText mPhoneNumber;
protected EditText mAddressLine1;
protected EditText mAddressLine2;

if (validationError) {
validationErrorMessage.append(getString(R.string.error_join));
}

validationErrorMessage.append(getString(R.string.error_blank_password));

validationErrorMessage.append(getString(R.string.error_mismatched_passwords));
}
validationErrorMessage.append(getString(R.string.error_end));
//Append validationErrorMessage with the appropriate error strings as well as set validationError as errors are detected
if (validationError) {
Toast.makeText(PinsActivity.this, validationErrorMessage.toString(), Toast.LENGTH_LONG).show();
return;
}
}
}
答案 0 :(得分：1)
我通过使用bundle传递数据然后在最后一个活动上将数据上传到Parse来解决了这个问题。谢谢你。
