如何检查电话号码是否有效？长度达到13(包括+前面的角色).

我怎么做？

我试过这个:

String regexStr = "^[0-9]$";

String number=entered_number.getText().toString();  

if(entered_number.getText().toString().length()<10 || number.length()>13 || number.matches(regexStr)==false  ) {
    Toast.makeText(MyDialog.this,"Please enter "+"\n"+" valid phone number",Toast.LENGTH_SHORT).show();
    // am_checked=0;
}`

我也试过这个:

public boolean isValidPhoneNumber(String number)
{
     for (char c : number.toCharArray())
     {
         if (!VALID_CHARS.contains(c))
         {
            return false;
         }
     }
     // All characters were valid
     return true;
}

两者都不起作用.

输入类型: + sign to be accepted and from 0-9 numbers and length b/w 10-13 and should not accept other characters

我得到错误 inflating fragment error while running calling an Activity which having fragments.

CheckList是包含的Activity,listview and Description fragments.其xml代码是:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="horizontal"
        android:layout_width="match_parent" android:layout_height="match_parent">

        <fragment class="com.uday.honeytest.CheckList$listview"
                android:id="@+id/titles" android:layout_weight="1"
                android:layout_width="0px" android:layout_height="match_parent" />

        <fragment class="com.uday.honeytest.CheckList$Description"
        android:id="@+id/details" android:layout_weight="1"
                android:layout_width="0px" android:layout_height="match_parent"
                android:background="?android:attr/detailsElementBackground" />

    </LinearLayout>

CheckList类是:

public class CheckList extends Activity {

    static int position=0;
    static CheckList check;

    public void onCreate(Bundle saved){

        super.onCreate(saved);
        setContentView(R.layout.checklist);


    }

    public static class listview extends ListFragment {

            View mConverView;
            String[] items;



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

            public View …

我不断得到,这个错误 logcat

我有一个bitmap,所以我想上传一个webserivceas字符串,并想要检索字符串.

使用以下命令将位图转换为字符串am:

ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();

strBase64 = Base64.encodeToString(byteArray, Base64.URL_SAFE);

以上String内容用作soapobject上传的属性.

但是Out of memory on a 11674900-byte allocation在打印和上传时我会得到.

如果我调试了问题,没有打印我得到

com.sun.jdi.InvocationException occurred invoking method.

上 soaprequest.

如何解决此问题以及upload image作为字符串的webservice？

我的清单启动器活动如下:

 <activity android:name=".CBMainMenu" android:screenOrientation="portrait" android:windowSoftInputMode="adjustPan" 
                  >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.LAUNCHER" /> 

                <data android:scheme="linkedinapp" android:host="connect" />
            </intent-filter>

其他应用程序正确安装,但为什么这个应用程序没有？我可以看到这个应用程序,Applications>Manage Applications但它在快捷方式中丢失.

这是我的完整清单:

      package="com.check.careerbuilder"

我有日期的字符串形式:

2011-03-27T09:39:01.607

我想格式化它 March 27, 2011

我在用

DateFormat[] formats = new DateFormat[] {
DateFormat.getDateInstance(), DateFormat.getDateTimeInstance(),
         DateFormat.getTimeInstance(), };
String actDate= formats[0].format(uploadeddate.substring(0,9));

但它不起作用.

我如何转换为March 27, 2011？

我有你的链接,如http://www.youtube.com/v/YR71GnQ4CU4?f=videos&app=youtube_gdata,然后如何将其转换为RTSP格式在VideoView中播放.

我用这个搜索gdata api:http://gdata.youtube.com/feeds/api/videos？&max-results = 20&v = 2&format = 1&q ="+ URLEncoder.encode(activity.criteria)但我找不到如何获得相关的RTSP网址.

我们将 Google pay 与标记化类型集成为 TOKENIZATION_DIRECT，并添加了 public_key 作为参数。

.setPaymentMethodTokenizationType( WalletConstants.PAYMENT_METHOD_TOKENIZATION_TYPE_DIRECT) .addParameter("publicKey", "...key..")

但是，交易失败，错误代码为 409，这意味着根据文档

不能立即恢复的错误。买家账户有问题（例如关闭账户、不受支持的国家/地区）

我们验证了关闭和不受支持的国家/地区的原因，两者都可以。还能是什么原因？

我有字符串发布日期,如:

2011-03-27T09:39:01.607

并且有当前日期.

我希望以下列形式区分这两个日期:

2 days ago 
1 minute ago etc..

取决于发布日期.

我使用此代码将发布日期转换为毫秒:

public long Date_to_MilliSeconds(int day, int month, int year, int hour, int minute) {
    Calendar c = Calendar.getInstance();
    c.set(year, month, day, hour, minute, 00);
    return c.getTimeInMillis();
}

这个当前日期: long now = System.currentTimeMillis();

并计算差异:

String difference = (String) DateUtils.getRelativeTimeSpanString(time,now, 0);

但它返回像May 1 , 1970或什么..

如何区分过帐日期和当前日期.

当运行eclipse时,应用程序每次都会崩溃

LinearAlloc超出容量(5242880),最后= 208

这种情况正在发生,当我创建AsyncTask时,奇怪的是每次都会发生这种情况.什么时候评论并运行它的运行.
