小编new*_*day的帖子

我有阿拉伯语文本,因此我将重力设置为右,以便从右侧开始文本.文字从现在开始.但另一个问题是文本开始从页面顶部呈现.但我需要垂直居中文本.虽然我尝试了几种变化,但我无法将其垂直居中.

这是我的xml文件的示例.

<LinearLayout
            android:id="@+id/linearLayout5"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="right"
            android:orientation="vertical" >

            <TextView
                android:id="@+id/textView2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_vertical"
                android:layout_marginBottom="23dp"
                android:gravity="right"
                android:padding="@dimen/padding_maintextview"
                android:text="@string/text"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textSize="20sp" />
        </LinearLayout>

问题在于上面的textview.

这里我放了整个xml文件.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"

        android:layout_width="196dp"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:gravity="center_horizontal"
        android:paddingTop="@dimen/padding_Title_Top"
        android:text="@string/text"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:textSize="20sp" />

    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView1"
        android:gravity="center_horizontal"
        android:orientation="vertical" >

        <View
            android:id="@+id/view1"
            android:layout_width="fill_parent"
            android:layout_height="5dp" />
    </LinearLayout>

    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_above="@id/linearLayout2"
        android:layout_below="@id/linearLayout1"
        android:layout_gravity="center"
        android:padding="@dimen/padding_maintextview" >

        <LinearLayout
            android:id="@+id/linearLayout5"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="right"
            android:orientation="vertical" >

            <TextView
                android:id="@+id/textView2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_vertical"

Chrome开发者工具的" 资源"选项卡下的会话存储是什么？

会话是服务器端功能,无法从前端访问.

可以使用Ctrl+ shift+ I快捷方式访问开发人员工具.

我正在尝试运行我的第一个ASP.NET MVC应用程序.我创建了一个cotroller和视图.数据来自数据库.但是,当项目可以运行但是当我尝试浏览客户页面时,我会收到以下错误.

传递到字典中的模型项的类型为'System.Collections.Generic.List`1 [MvcApplication3.Models.Customer]',但此字典需要类型为"MvcApplication3.Models.Customer"的模型项.

我在这里有点困惑,因为错误说它已经请求了模型类型.

我的应用程序没问题,直到我注意到这一点:有时应用程序崩溃.当它发生时,我检查logcat.

01-08 06:12:07.123: E/ThrottleService(755): problem during onPollAlarm: java.lang.IllegalStateException: problem parsing stats: java.io.FileNotFoundException: /proc/net/xt_qtaguid/iface_stat_all: open failed: ENOENT (No such file or directory)

问题是我无法调试它.并没有提示错误.它也发生在我的移动设备上.这样的应用程序崩溃的原因是什么？

我正在阅读一本电子书,它有以下xml代码.

我在ASP.NET上找到了以下内容.我正在学习并对以下内容感到好奇.

IL体系结构的第二个主要优点是它使Framework能够与语言保持中立.在很大程度上,语言选择不再取决于任何语言相对于另一种语言的能力,而是取决于他们对开发者或tam的偏好.您甚至可以在单个应用程序中混合语言.用C#编写的类可以从VB2005类派生,并且在C @方法中抛出的异常可以在VB @ 005方法中捕获.

我的问题是,ASP.NET是否使用相同的编译器来编译VB.net和C#？

更新:(另一个查询)

C#编译器可以编译VB.Net代码吗？

我想获得子聚合.

                   "format" : "dd/MM/yyyy",

                  }

我正在尝试从头开发一个网站.这是代码

<html>
<head>
</head>
<body >
<div id="top" style="height:200px;background-color:green">
</div>
<div id="middle" style="height:800px;background-color:white">
</div>
<div id="footer" style="height:200px;background-color:green">
</div>

</body>
</html>

问题是div标签上方有一个空白区域.我可以使用margin: -10px;属性删除空格.但我不喜欢这样处理.有没有办法在css中以体面的方式处理这个问题？

我正在为Android应用程序设计一个布局.这是布局的骨架.

我尝试的是使用表格布局,因为GUI可以分成表格行和列.基本上,我想把布局分成两列,如你所见.这是xml代码

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tableLayout1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <!-- 2 columns -->
    <TableRow
        android:id="@+id/tableRow1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="5dip" >

        <View
            android:id="@+id/view1"
            android:layout_weight="7"
            android:layout_width="0dp"
            android:layout_height="wrap_content">
            <TextView
                android:id="@+id/textView1"
                android:text="Column 1"
                android:textAppearance="?android:attr/textAppearanceLarge" />
        </View>

        <View
            android:id="@+id/view2"
            android:layout_weight="3"
            android:layout_width="0dp"
            android:layout_height="wrap_content" >
            <Button
                android:id="@+id/button1"
                android:text="Column 2" />
        </View>

    </TableRow>


</TableLayout>

我在GUI中遇到以下错误

Exception raised during rendering: android.view.View cannot be cast to android.view.ViewGroup

我认为这表示我们无法对观点进行分组.如果不可能,该如何处理.我来自网络背景.我以为我可以将视图用作html中的div.
