小编dio*_*sus的帖子

我正在开发一个Android应用程序,我对是否应该使用Ormlite与Android内容提供程序一起更新和检索数据感到矛盾.内容提供程序将主要用于通知应用程序其他平台上应用程序中发生的数据更改.也许我让它变得比它需要的更复杂.一些更有经验的意见将不胜感激!

我有一个正在反应的表单，我正在使用材质 UI 文本字段。我希望 TextField 中存在一个值，并且当我使用 Google Chrome 的“检查”选项时可以看到该值正在设置。除此之外，我还看到 type="hidden"。我已将其更改为 type="text" 但无济于事，该值仍然未显示。很好奇这里是否有人了解为什么会发生这种情况。以下是导致问题的主要代码：

        <TextField
            name="Property"
            select
            fullWidth
            margin="normal"
            className={clsx(selectInputStyle.margin, selectInputStyle.textField, selectInputStyle.root)}
            value={viewProperties[index].name}
            onChange={this.handleSelectChange}
          >
            {propertyKeys.map((key, index) => (
              <MenuItem value={key} key={index}>
                {key}
              </MenuItem>
            ))}
          </TextField>

这是完整的代码文件，只是为了了解正在发生的事情的完整上下文。

    import React, { Component } from 'react';
    import { Container, Form, Button, Row, Col, Nav, NavItem, NavLink, Input, FormGroup } from 'reactstrap';
    import { connect } from 'react-redux';
    import { reduxForm, FieldArray, arrayRemoveAll } from 'redux-form/immutable';
    import * as Immutable from 'immutable';
    import _ from 'lodash'; …

我正在尝试创建自定义ListView.当我测试我的代码时,我收到以下错误

03-09 19:21:10.425: E/AndroidRuntime(379): java.lang.RuntimeException: Unable to start      activity ComponentInfo{com.anomaly.punchlist/com.anomaly.punchlist.TeamActivity}: java.lang.IllegalArgumentException: No view found for id 0x7f08000c for fragment TeamListFragment{4067a358 #0 id=0x7f08000c}

除了阅读Fragments,ListFragments和ListViews上的Android Docs之外,我在发布此问题之前引用了以下链接.

链接1:FragmentActivity onCreateView
链接2:在Android
链接3 上使用ListFragment的问题:Android片段没有找到ID的视图？
链接4:Android ListFragment令人困惑的
链接5:如何从FragmentActivity更新ListFragment中的ListView？
链接6:使用自定义视图填充ListFragments？

我有TeamActivity类,它扩展了FragmentActivity和TeamListFragment,扩展了ListFragment并实现了LoaderManager.LoaderCallbacks.请参阅以下代码:

TeamActivity.java

package com.anomaly.punchlist;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;

public class TeamActivity extends FragmentActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    FragmentManager fragmentManager = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction =  fragmentManager.beginTransaction();
    TeamListFragment teamListFragment = new TeamListFragment();
    fragmentTransaction.add(R.id.android_teamList, teamListFragment); …

目前我有一个为Hibernate和JNDI配置但在Tomcat服务器上运行的应用程序.我的任务是将这个Web应用程序移动到JBOSS 5.1.到目前为止我做了以下事情:

1. 已删除hibernate-3.2.1.ga.jar,hibernate-annotations-3.3.0.ga.jar以及hibernate-commons-annotations-3.3.0.ga.jar从我要部署的Web应用程序中删除.
2. 我已添加ojdbc.5 jar到/default/conf/lib目录中.

我有以下配置的Web应用程序文件:

FILE1:hibernate.cfg.xml

    <session-factory>
          <property name="hibernate.connection.datasource">java:comp/env/jdbc/ldcDataSource</property>

          <property name="hibernate.current_session_context_class">thread</property>

          <property name="hibernate.format_sql">true</property>

在我的盒子上本地运行应用程序时,应用程序运行正常.部署到QA时,会收到以下错误.我在本地和QA运行Tomcat 5.5.23.该应用程序还使用Spring MVC.
