我从得到一些值Activity,并在得到这些onActivityResult(),onActivityResult()被调用但收到的数据是null CODE的MainActivity

@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
    // TODO Auto-generated method stub

    if(item.getItemId() == R.id.action_settings){
        Intent intent = new Intent(MainActivity.this, AddDetailActivity.class);
        startActivityForResult(intent, request_code);
    }
    return true;
}


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == request_code){
        if(resultCode == RESULT_OK){

            String name = data.getExtras().getString(AddDetailActivity.NAME_KEY);
            String address = data.getExtras().getString(AddDetailActivity.ADDRESS_KEY);

            Toast.makeText(MainActivity.this, "Name is : " + name + " …

我想限制EditText只获取Text,而不是任何数字.我试过这个:

1--在XML中:

        <EditText android:id="@+id/editText1" android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:hint="@string/search_prompt"
        android:inputType="text"/>

这不适合我.

2--在Java代码中得到引用Text Only输入EditText android

myEditText.setInputType(InputType.TYPE_TEXT_VARIATION_NORMAL);

但这也行不通.

我正在json从OpenWeathermap.org解析数据,如下所示:

{
   "cod":"200",
"message":0.0016,
"city":{
  "id":1164408,
  "name":"Sukkur",

     "lon":68.857384,
     "lat":27.70516
  },
  "country":"PK",
  "population":0,
  "sys":{
     "population":0
  }  },  

"cnt":2,
"list":[
  {
     "dt":1394175600,
     "temp":{
        "day":26.31,
        "min":20,

        "night":22.71,
        "eve":30.17,
        "morn":20
     },

     "humidity":59,
     "weather":[
        {
           "id":801,

           "icon":"02d"
        }
     ],

  },
  {

在看了这个SO问题之后,我把Model.java上面的 …

我正在检索我的Android应用程序的JSON对象.他们有两个领域:date和time.在布局上,我需要从这两个字段中提取以下字符串:

1. 星期几(例如星期一)
2. 每月的某一天(例如21)
3. 月份(例如四月)
4. 年份(例如2014年)
5. 小时(例如17)
6. 分钟(例如35)

这些领域是date="2014-04-21",time="17:35:00"

我怎么能这样做？

我有一张表格

<form:form method="post" commandName="post" htmlEscape="false">
    <form:input cssClass="input-field" path="postTitle" placeholder="Post title"/>            
    <form:textarea id="editor" placeholder="Post" path="postBody"/>
    <input type="hidden" id="tagQuery" type="text" placeholder="tags" class="input-field"/><br> 
    <ul id="mytags"></ul><br><br>          
    <form:select style="visibility : hidden;" id="tags" path="tags">
    </form:select>
    <input type="submit" value="Save Post"/>    
</form:form>

我使用tagit lib获取标签,因为我已经配置了它

select = document.querySelector("select[name='tags']");    
jQuery(document).ready(function() {
    jQuery("#mytags").tagit({
        singleField: true,
        singleFieldNode: $('#tagQuery'),
        allowSpaces: true,
        minLength: 2,
        removeConfirmation: true,
        tagSource: function( request, response ) {
            //console.log("1");
             $.getJSON("/app/getTags", request, function(result) {
                response($.map(result, function(item) {
                    return {
                        // following property gets displayed in drop down
                        label: item.tagTitle,
                        // following …

我想映射问题和选项之间的关系。

@Entity
public class Question implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long questionId;
    private String questionText;
    private Integer questionChoices;
    private Integer questionNumbers;

    @ManyToOne
    @JoinColumn(name = "quizId")
    private Quiz quiz;

    @OneToMany(mappedBy = "question", cascade = CascadeType.ALL)
    private Set<Option> options = new HashSet<Option>();

    @OneToOne
    @JoinColumn(name = "answerId")
    private Answer answer;
    // omitting setters and getters hashcode equals methods
}

和

@Entity    
public class Option implements Serializable {    

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long …

嗨,我想在活动中制作一个按钮.我创建了一个,但在2D中像这个图像.

如何在这个图像中进行3D制作 ？
