小编mum*_*mum的帖子

我在布局中创建了一个TimePicker,我希望它以格式24h显示时间.

你能帮助我吗？谢谢.

我正在使用以下代码显示ProgressDialog:

void showProccess() {    
    p = new ProgressDialog(this);
    p.setTitle("PleaseWait");                   
    p.setMessage("data loading");
    p.show();
}

在Android 2.3.1 ProgressDialog中显示a时,我无法点击Activity.但是在Android 4.0.3中,我点击Activity并ProgressDialog退出.我想要ProgressDialog不退出,就像Android 2.3.1一样.你能帮助我吗？谢谢.

我的代码设置了MediaRecorder,它在行集质量上显示错误

mMediaRecorder = new MediaRecorder();

   // Step 1: Unlock and set camera to MediaRecorder
   mCamera.stopPreview();
   mCamera.unlock();
  mMediaRecorder.setCamera(mCamera);

  mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
    mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
    mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    mMediaRecorder.setProfile(CamcorderProfile .get(CamcorderProfile.QUALITY_HIGH));
    mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
    mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);

    // Step 4: Set output file
    mMediaRecorder.setOutputFile(getOutputMediaFile(MEDIA_TYPE_VIDEO).toString());

    // Step 5: Set the preview output
    mMediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());

    // Step 6: Prepare configured MediaRecorder
   try {
    mMediaRecorder.prepare();
        Log.d("DEBUG", "IllegalStateException preparing MediaRecorder: "
                        + e.getMessage());
                releaseMediaRecorder();
                return false;
   } catch (IOException e) {
                Log.d("DEBUG",
                        "IOException preparing MediaRecorder: " + e.getMessage());
                releaseMediaRecorder();
                return false;
   }

例如:

java.lang.IllegalStateException

堆栈跟踪:

java.lang.IllegalStateException

我将输入文件设计为：

 <input type="file" name="file" id="file" size="52"   />      

我想更改按钮“浏览...”的文本和颜色。你能帮助我吗？谢谢大家。

在Joomla我使用以下代码发送邮件:

function sendmail($file,$mailto)
{  
    $mailer =& JFactory::getMailer();
    //var_dump($mailer); exit;
    $config =&JFactory::getConfig();
    $sender = array( 
        $config->getValue( 'config.mailfrom' ),
        $config->getValue( 'config.fromname' )
    );

    $mailer->setSender($sender);         

    $recipient = array($mailto);           
    $mailer->addRecipient($recipient);

    $body   = "Your body string\nin double quotes if you want to parse the \nnewlines etc";
    $mailer->setSubject('Your subject string');
    $mailer->setBody($body);
    // Optional file attached

    $mailer->addAttachment(JPATH_BASE.DS.'CSV'.DS.$file);

    $send =&$mailer->Send();

    if ( $send !== true ) {
        echo 'Error sending email: ' . $send->message;
    } else {
        echo 'Mail sent';
    }
}

这是Joomla中的函数sendmail:带有$file文件zip的路径,$mailto是我的gmail.当我发送邮件时,我收到错误:

function …

在PostgreSQL:我转换string到timestamp用to_timestamp():

select * from ms_secondaryhealthcarearea
where to_timestamp((COALESCE(update_datetime, '19900101010101'),'YYYYMMDDHH24MISS') 
    > to_timestamp('20121128191843','YYYYMMDDHH24MISS')

但我得到这个错误:

ERROR:  syntax error at end of input
LINE 1: ...H24MISS') >to_timestamp('20121128191843','YYYYMMDDHH24MISS')
                                                                       ^
********** Error **********

ERROR: syntax error at end of input
SQL state: 42601
Character: 176

为什么？如何转换string为timestamp？

我使用以下方法在PHP中导出了一个xml文件:

$xmldoc = new DOMDocument();        
$xmldoc->formatOutput = true;
$xmldoc->encoding="Shift_JIS";

// create root nodes
$root = $xmldoc->createElement("TableData");
$xmldoc->appendChild( $root );
$xmldoc->save($filename);

结果:

<?xml version="1.0" encoding="Shift_JIS"?>
<TableData> </TableData>

现在,我想添加如下行 <!DOCTYPE TableDef SYSTEM "TableData.dtd">:

    <?xml version="1.0" encoding="Shift_JIS"?>
    <!DOCTYPE TableDef SYSTEM "TableData.dtd">
   <TableData> </TableData>

如何添加DOCTYPE导出的xml？谢谢.

我的代码转到最后一个arraylist:

 if (listItem.get(listItem.size() - 1).SortNo > 0) {
                    while (listItem.get(0).SortNo == 0) {

                        DTO_NightClinic dt = listItem.get(0);
                        listItem.remove(0);
                        listItem.add(dt);
                    }
                }

但通常listItem.remove(0);不起作用.第一项仍然存在于arraylist的第一个位置.

活动不是自动旋转:

       <activity
            android:name=".E028"
            android:label="@string/app_name"
            android:screenOrientation="portrait"
            android:theme="@android:style/Theme.Black.NoTitleBar" >
        </activity>

如果我使用onConfigurationChanged,它不起作用:

@Override
    public void onConfigurationChanged(Configuration newConfig) {
        // TODO Auto-generated method stub
        super.onConfigurationChanged(newConfig);
        if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
            Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
        } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
            Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
        }
    }

当Ativity不自动旋转时,如何检查手机的状态是横向还是纵向？

我想这种情况:我必须使用传感器

我的代码:

@Override
    public void onSensorChanged(SensorEvent event) {
        // TODO Auto-generated method stub
        if (event.values[1] < 6.5 && event.values[1] > -6.5) {
            if (orientation != 1) {
                Log.d("Sensor", "Landscape");
                // listImage.notifyDataSetChanged();
            }
            orientation = 1;
        } else { …

我收到以下致命错误:

致命错误:在第67行的/var/www/html/dai/components/com_servicemanager/views/i0602/view.html.php中调用未定义的函数mb_convert_encoding()

我创建了一个文件CSV:

<?php

$dateTimeNow = ...

$list = $this->get('DataCSV'); 

$filename = 'CSV_' . $dateTimeNow . '.csv';

foreach ($list as $item)
{ 
    $csv .= join("\t", $item)."\r\n"; 
}  

$csv = chr(255) .chr(254) . mb_convert_encoding($csv, "UTF-16LE", "UTF-8");


header("Content-type: application/x-msdownload");
header("Content-disposition: csv; filename=$filename; size=" . strlen($csv));
echo $csv;
exit;

我在窗口上运行窗口是好的.但我把服务器放在Centos上,它无法创建文件csv.为什么？你能帮助我吗？谢谢.
