我一直在努力让facebook练习应用程序正常工作,我不能为我的生活弄清楚为什么我不能引用Facebook SDK中的LoginButton.下面是我在查看定义LoginButton的布局时遇到的错误.

<com.facebook.widget.LoginButton
    android:id="@+id/authButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="30dp"
    />

The following classes could not be instantiated:
- com.facebook.widget.LoginButton (Open Class, Show Error Log)
See the Error Log (Window > Show View) for more details.
Tip: Use View.isInEditMode() in your custom views to skip code when shown in Eclipse

我正在尝试将位图图像保存到手机内的目录(图库)中.该应用程序正在Xamarin中开发,因此代码是C#.

我似乎无法弄清楚如何创建目录,并保存位图.有什么建议？

public void createBitmap(View view){ 
    view.DrawingCacheEnabled = true; 
    view.BuildDrawingCache (true); 
    Bitmap m_Bitmap = view.GetDrawingCache(true);

    String storagePath = Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
    Java.IO.File storageDirectory = new Java.IO.File(storagePath);
    //storageDirectory.mkdirs ();


    //save the bitmap
    //MemoryStream stream = new MemoryStream ();
    //m_Bitmap.Compress (Bitmap.CompressFormat.Png, 100, stream);
    //stream.Close();


    try{

        String filePath = storageDirectory.ToString() + "APPNAME.png";
        FileOutputStream fos = new FileOutputStream (filePath);
        BufferedOutputStream bos = new BufferedOutputStream(fos);
        m_Bitmap.Compress (Bitmap.CompressFormat.Png, 100, bos);
        bos.Flush();
        bos.Close();
    } catch (Java.IO.FileNotFoundException e) {
        System.Console.WriteLine ("FILENOTFOUND");
    } catch (Java.IO.IOException e) {
        System.Console.WriteLine ("IOEXCEPTION");
    }

我正在开发的应用程序中实现Paho MQTT Android服务.在测试了Paho提供的示例应用程序之后,我发现有一些事情我想改变.

https://eclipse.org/paho/clients/android/

应用程序完全关闭后,应用程序服务似乎会关闭.我希望即使在应用程序关闭后,如果有更多消息进入,我也会保持服务运行.我也在寻找一种方法,一旦收到新消息,就可以将应用程序打开到特定的活动.

这是在消息到达时调用的回调之一,我尝试实现一个简单的startActivity来打开一个特定的活动但是如果应用程序关闭/不再运行它就不起作用.

如果有人使用过PAHO MQTT Android服务,是否有一种特定的方法可以在应用程序关闭时阻止服务停止,如何在消息到达时重新打开应用程序？

    /**
   * @see org.eclipse.paho.client.mqttv3.MqttCallback#messageArrived(java.lang.String,
   *      org.eclipse.paho.client.mqttv3.MqttMessage)
   */
  @Override
  public void messageArrived(String topic, MqttMessage message) throws Exception {

    // Get connection object associated with this object
    Connection c = Connections.getInstance(context).getConnection(clientHandle);

    // create arguments to format message arrived notifcation string
    String[] args = new String[2];
    args[0] = new String(message.getPayload());
    args[1] = topic + ";qos:" + message.getQos() + ";retained:" + message.isRetained();

    // get the string from strings.xml and format
    String messageString = …

我在使用Activities和Fragments时遇到了一些麻烦.我处于应用程序开发的早期阶段,我最终希望设计出集成两个独立屏幕的最有效方式.

第一个屏幕是"启动画面",它会向用户显示徽标,输入用户信息并通过数据库或Facebook登录.还有一个按钮可供用户注册该应用程序.

第二个屏幕将允许用户通过定义他的用户信息来设置帐户,并且将包括注册按钮以及与Facebook按钮的连接.

我想知道每个人如何处理手头的任务,因为我最初设计的应用程序指定2个活动来处理每个屏幕.最近,我已经切换到能够将屏幕作为2个片段托管在1个活动下.

每种方法有哪些好处,您会选择哪种设计？

我试图让我的用户选择使用 Google 或 Facebook 登录。到目前为止，我找到了一个实现 Google 登录流程的示例，但是如果我可以在同一个 Activity 中实现类似的 Facebook 登录流程，我感到很困惑。

任何人都有处理登录的想法？我正在考虑可能定义一个类来处理 Google/Facebook 的登录流，也许只是检查应用程序启动时正在使用哪个。有任何想法吗？

public class MainActivity extends Activity implements ConnectionCallbacks,
    OnConnectionFailedListener, OnClickListener, OnAccessRevokedListener {

private static final String TAG = "MainActivity";

// A magic number we will use to know that our sign-in error
// resolution activity has completed.
private static final int OUR_REQUEST_CODE = 49404;

// The core Google+ client.
private PlusClient mPlusClient;

// A flag to stop multiple dialogues appearing for the user.
private boolean mResolveOnFail;

// …

我正在尝试创建一个类似于a的简单对话框DatePickerDialog.的Dialog,我应该创造提供,他们可以选择像阵列的用户.

我相信我已经设法创建了数组并为其添加了正确的图像,我现在遇到的问题是如何让它Dialog出现？我该怎么回事？

我已经研究过AlertDialogs这样,但我不确定如何实施它们.

更新:固定问题,代码显示在下面是功能

图片采摘

public class PicturePickerFragment extends DialogFragment {

ArrayList<Integer> imageList = new ArrayList<Integer>();

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // fill an array with selected images

    String title = "Picture";

    imageList.add(R.drawable.barbershop);
    imageList.add(R.drawable.wedding);
    imageList.add(R.drawable.meeting);
    imageList.add(R.drawable.barbershop);

    // return alertdialog
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    LayoutInflater inflater = getActivity().getLayoutInflater();

    // Inflate and set the layout for the dialog
    // Pass null as the parent view because its going in the dialog layout …

我在尝试编辑NetSuite中的CUSTOMER记录时遇到了以下问题.我创建的脚本非常简单.

如果用这么简单的代码,我怎么可能做错呢？

{"type":"error.SuiteScriptModuleLoaderError","name":"MODULE_DOES_NOT_EXIST","message":"Module does not exist: /SuiteScripts/BillingInfoUpdated.js","stack":[]}

脚本:

define(['N/log'], function (log) {

    /**
     * User Event 2.0 example showing usage of the Submit events
     *
     * @NApiVersion 2.x
     * @NModuleScope SameAccount
     * @NScriptType UserEventScript
     * @appliedtorecord customer
     */
    var exports = {};

    function afterSubmit(scriptContext) {
        log.debug({
            "title": "After Submit",
            "details": "action=" + scriptContext.type
        });
    }

    exports.afterSubmit = afterSubmit;
    return exports;
});

我最近将手机更新到了 Android 5.0.2，现在我正在开发的一个应用程序的工具栏出现了故障。工具栏被向上推，并被最顶部的状态栏部分隐藏。

什么会导致这个问题？

这是具有处理工具栏的布局的活动的代码

public class LeftMenusActivity extends ActionBarActivity implements FeedFragment.OnFragmentInteractionListener, UserFragment.OnFragmentInteractionListener,
        SettingsFragment.OnFragmentInteractionListener, CreateFragment.OnFragmentInteractionListener, TimersFragment.OnFragmentInteractionListener,
        CalendarFragment.OnFragmentInteractionListener, DetailFragment.OnFragmentInteractionListener, SingleWorkoutItemDetailFragment.OnFragmentInteractionListener {

    public static final String LEFT_MENU_OPTION = "com.modup.app.LeftMenusActivity";
    public static final String LEFT_MENU_OPTION_1 = "Left Menu Option 1";
    public static final String LEFT_MENU_OPTION_2 = "Left Menu Option 2";

    private ListView mDrawerList;
    private List<DrawerItem> mDrawerItems;

从Salesforce中使用Google OAuth时,我收到400错误请求.以下错误与invalid_type无效有关,但如果您查看"使用刷新令牌"下的文档,您将看到它是正确的.

https://developers.google.com/identity/protocols/OAuth2WebServer

错误:

{
 "error": "unsupported_grant_type",
 "error_description": "Invalid grant_type: "
}

我正在尝试使用refresh_token交换访问令牌,并且可以使用CURL使用以下代码成功完成.

curl \
  -d refresh_token=REFRESH_TOKEN \
  -d client_id=CLIENT_ID \
  -d client_secret=CLIENT_SECRET \
  -d grant_type=refresh_token https://www.googleapis.com/oauth2/v4/token

我在Salesforce中使用的代码:

    Http http = new Http();
    HttpRequest req = new HttpRequest();

    req.setHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
    req.setHeader('Content-Length', '0');
    req.setHeader('client_id', 'CLIENT_ID');
    req.setHeader('client_secret', 'CLIENT_SECRET');
    req.setHeader('refresh_token', 'REFRESH_TOKEN');
    req.setHeader('grant_type', 'refresh_token'); 

    req.setEndpoint('https://www.googleapis.com/oauth2/v4/token');
    req.setMethod('POST');

    return http.send(req);

我无法理解这个错误意味着什么.

org.mozilla.javascript.EcmaError:ReferenceError:未定义"nlapiSearchRecord".(/SuiteScripts/PreventDuplicateCustomer.js#35)

我正在尝试创建一个脚本,该脚本根据应该是唯一的特定字段搜索重复记录.我想使用以下脚本阻止在NetSuite中创建重复的"CUSTOMER"记录. "

我遇到了我的API问题,我无法创建用户记录/将其存储在Google数据存储区中.我收到下面列出的JSON响应.

我发现奇怪的另一件事是当它在右上角使用Google API Explorer时,它有一个红色感叹号,上面写着"方法需要授权".它希望我为用户电子邮件授权OAUTH Scope.

更新:这是我通过GAE获得的错误日志.

我试图根据搜索结果停止创建记录.我似乎无法通过我的SuiteScript搜索返回任何数据,即使我知道数据存在的事实.

我使用下面使用的确切过滤器创建了一个自定义保存的搜索,并返回我正在寻找的结果.
