我尝试创建半圆背景,在development IDE preview它工作,但当我在模拟器中启动它不起作用.

这是我的形状代码:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:height="50dp">
        <shape>
            <solid android:color="@color/colorAccentDark" />
        </shape>
    </item>
    <item android:top="-500dp" android:bottom="0dp" android:left="-100dp" android:right="-100dp">
        <shape>
            <corners android:radius="500dp" />
            <solid android:color="@color/colorAccentDark" />
        </shape>
    </item>
</layer-list>

这是我的布局代码:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/background_profile"
        android:layout_weight="1">

        <de.hdodenhof.circleimageview.CircleImageView
            android:id="@+id/profile_avatar"
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:src="@drawable/ic_default_avatar"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="50dp"/>

        <TextView
            android:id="@+id/profile_name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_below="@id/profile_avatar"
            android:layout_marginTop="20dp"
            android:textColor="@color/neutralWhite"
            android:textStyle="bold"
            android:textSize="18sp"
            android:text="Avatar Ang"/>

    </RelativeLayout>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="4.04">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Hello Android!"/>

    </RelativeLayout>

</LinearLayout>

也许还有其他任何调整来处理它？谢谢

我在Ubuntu 13.10中的Apache 2.4中遇到了问题.我尝试将Document Root更改为/ home/fandi/public_html并且一切正常.但我尝试在我的public_html /我创建文件夹得到这样的错误:

[Sat Jan 25 10:59:50.149441 2014] [autoindex:error] [pid 1093] [client 127.0.0.1:39901] AH01276: Cannot serve directory /home/fandi/public_html/report_php/: No matching DirectoryIndex (index.html,index.cgi,index.pl,index.php,index.xhtml,index.htm) found, and server-generated directory index forbidden by Options directive

我必须创建文件index.html,index.php以及其他index.xxx文件.

默认情况下,它必须显示目录索引.如何启用目录索引？

这是我的档案000-default.conf:

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /home/fandi/public_html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    <Directory "/home/fandi/public_html">
        Options All
        AllowOverride All
        Require all granted
        Options Indexes FollowSymLinks
    </Directory>

</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

请帮助,谢谢^^之前

我是使用Apache Common vfs的新手,我成功连接到我已经阅读过docs的服务器但是我坚持使用这段代码.我如何列出目录/文件？

....
Session session = null;
        FileSystemManager fsManager = null;
        FileSystem fs = null;
        try {
            String host = "host_here";
            int port = 22;

            String userStr = "user_here";
            char [] username = userStr.toCharArray();

            String passStr = "password_here";
            char [] password = passStr.toCharArray();

            session = SftpClientFactory.createConnection(host, port, username, password, null);
            //session.connect();

            System.out.println("Connected to the server");

            FileSystemOptions opts = new FileSystemOptions();
            fsManager = VFS.getManager();
            FileObject file = fsManager.resolveFile("ftp://"+userStr+":"+passStr+"@"+host+"/home/", opts);

我只想选择 Oracle 数据库中的第 1 个和第 20 个日期。这是我的查询。

SELECT INVOICE_DATE 
FROM invoice_debt@stilng1_lngrpt2 
WHERE INVOICE_DATE = TO_DATE('01', 'DD')
AND INVOICE_DATE = TO_DATE('20','DD')
AND INVOICE_DATE > TO_DATE('30-12-2010', 'DD-MM-YYYY')
AND INVOICE_DATE IS NOT NULL GROUP BY INVOICE_DATE 
ORDER BY INVOICE_DATE DESC;

我的查询运行如下：

1. 仅选择第一个日期
2. 仅选择第 20 个日期
3. 选择日期 > 2010 年 12 月 30 日

但没有任何记录返回。

我尝试使用EXTRACT获取日期，但我无法使用WHERE子句。

SELECT 
EXTRACT(DAY FROM TO_DATE(INVOICE_DATE, 'DD-MM-YY')) as DAY_EXTRACT 
FROM invoice_debt@stilng1_lngrpt2;

请帮助我谢谢。:)
