Android Studio（JAVA）编译警告:使用了未经检查或不安全的操作

在编译Android Studio（JAVA）程序时发生了如下的警告:

使用了未经检查或不安全的操作
要了解详细信息，请使用 "-Xlint:unchecked" 重新编译。

如何设置Android Stuido开启 "-Xlint:unchecked"

修改build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.a.b.c"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            minifyEnabled false
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.android.support:design:23.0.1'
}

apply plugin: 'com.android.application'

android {

compileSdkVersion 23

buildToolsVersion "23.0.1"

defaultConfig {

applicationId "com.a.b.c"

minSdkVersion 15

targetSdkVersion 23

versionCode 1

versionName "1.0"

}

buildTypes {

release {

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

debug {

minifyEnabled false

}

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

testCompile 'junit:junit:4.12'

compile 'com.android.support:appcompat-v7:23.0.1'

compile 'com.android.support:design:23.0.1'

}

增加

tasks.withType(JavaCompile) {
   options.compilerArgs << "-Xlint:unchecked"
}

tasks.withType(JavaCompile) {

options.compilerArgs << "-Xlint:unchecked"

}

修改后的如下：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.a.b.c"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            minifyEnabled false
        }
    }

    tasks.withType(JavaCompile) {
       options.compilerArgs << "-Xlint:unchecked"
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.android.support:design:23.0.1'
}

apply plugin: 'com.android.application'

android {

compileSdkVersion 23

buildToolsVersion "23.0.1"

defaultConfig {

applicationId "com.a.b.c"

minSdkVersion 15

targetSdkVersion 23

versionCode 1

versionName "1.0"

}

buildTypes {

release {

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

debug {

minifyEnabled false

}

tasks.withType(JavaCompile) {

options.compilerArgs << "-Xlint:unchecked"

}

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

testCompile 'junit:junit:4.12'

compile 'com.android.support:appcompat-v7:23.0.1'

compile 'com.android.support:design:23.0.1'

}

警告信息的处理例子

包含-Xlint:unchecked警告的代码

final LinkedHashMap<WeakReference<Object>,WeakReference<Object>> aWeakArray = new LinkedHashMap<>();
for (Iterator iter = aWeakArray.entrySet().iterator(); iter.hasNext(); ) {
	LinkedHashMap.Entry element = (LinkedHashMap.Entry)iter.next();
	WeakReference<Object> aWeakObj = (WeakReference<Object>)element.getKey();
	WeakReference<Object> aWeakTag = (WeakReference<Object>)element.getValue();
}

final LinkedHashMap<WeakReference<Object>,WeakReference<Object>> aWeakArray = new LinkedHashMap<>();

for (Iterator iter = aWeakArray.entrySet().iterator(); iter.hasNext(); ) {

LinkedHashMap.Entry element = (LinkedHashMap.Entry)iter.next();

WeakReference<Object> aWeakObj = (WeakReference<Object>)element.getKey();

WeakReference<Object> aWeakTag = (WeakReference<Object>)element.getValue();

}

消除警告后的代码如下：

final LinkedHashMap<WeakReference<Object>,WeakReference<Object>> aWeakArray = new LinkedHashMap<>();
for (Iterator<LinkedHashMap.Entry<WeakReference<Object>,WeakReference<Object>> > iter = aWeakArray.entrySet().iterator(); iter.hasNext(); ) {
	LinkedHashMap.Entry<WeakReference<Object>,WeakReference<Object>> element = iter.next();
	WeakReference<Object> aWeakObj = element.getKey();
	WeakReference<Object> aWeakTag = element.getValue();
}

final LinkedHashMap<WeakReference<Object>,WeakReference<Object>> aWeakArray = new LinkedHashMap<>();

for (Iterator<LinkedHashMap.Entry<WeakReference<Object>,WeakReference<Object>> > iter = aWeakArray.entrySet().iterator(); iter.hasNext(); ) {

LinkedHashMap.Entry<WeakReference<Object>,WeakReference<Object>> element = iter.next();

WeakReference<Object> aWeakObj = element.getKey();

WeakReference<Object> aWeakTag = element.getValue();

}

同样的方法适用于"-Xlint:deprecation"。

svnrdump dump 实现 SVN 库的远程导出

svnrdump dump 命令必须在 SVN 1.7版本以上提供的用于远程dump SVN库的命令.

以导出libyuv的svn库为例：

svnrdump dump http://libyuv.googlecode.com/svn/ > libyuv.dump

1	svnrdump dump http://libyuv.googlecode.com/svn/ > libyuv.dump

可以在这里下载已经DUMP完成之后的版本。目前的版本号是1444。

恢复DUMP文件到Subversion工程，请参考 Could not open the requested SVN filesystem

Debian和OpenMediaVault在命令行下设置更新源

很多时候我们比较纠结的问题是，“该把哪个Debian镜像发布站点加入source.list文件？”。

Ubuntu的图形界面中有一个测试工具，命令行下面的Debian也有一个现成的程序：netselect。

安装netselect

$ sudo apt-get install netselect

1	$ sudo apt-get install netselect

不带参数运行它时会显示它的帮助信息。运行它时加上以空格分隔的镜像主机列表，它会返回一个分值和列表中的一个主机名。这个分值通过评估ping time和hopsnumber（一个网络请求报文到达目标主机所经过的转发主机的个数）得出，它与镜像站点预计下载速度成反比（数值越小越好）。返回的主机名是主机列表中得分最低的那个（查看列表中所以主机的得分情况可使用-vv选项）。看出下的例子：

$ netselect http://mirrors.aliyun.com/debian/ http://mirrors.163.com/debian/

      5 http://mirrors.163.com/debian/

$ netselect http://mirrors.aliyun.com/debian/ http://mirrors.163.com/debian/

5 http://mirrors.163.com/debian/

它表示，在netselect后列出的所有主机中，http://mirrors.163.com/debian/是下载速度最快的主机，其得分为5。

注意，最近163的服务器不知道发生了何种故障，导致各种更新失败，尽管测试的结果是163更快，但是我们建议还是使用阿里云的服务器。

把netselect找到的连接速度最快的镜像站点手工加入/etc/apt/sources.list文件.

最新版本的netselect软件包包含了netselect-apt脚本，它使上述操作自动完成。只需将发布目录树做为参数（默认为stable）输入，sources.list文件就会生成速度最快的main和non-US镜像站点列表，并保存在当前目录下。

$ sudo apt-get install netselect-apt

$ netselect-apt stable

$ sudo mv /etc/apt/sources.list /etc/apt/sources.list.old

$ sudo mv sources.list /etc/apt/sources.list

$ sudo apt-get update

$ sudo apt-get install netselect-apt

$ netselect-apt stable

$ sudo mv /etc/apt/sources.list /etc/apt/sources.list.old

$ sudo mv sources.list /etc/apt/sources.list

$ sudo apt-get update

对于OpenMediaVault用户还是手工修改配置文件好了，主要是上面的工具生成的比较简略

JS常用方法封装

做项目是遇到一个封装的不错的Util类，写一下，长期备用：

CMD标准

define(function(require, exports, module) {
    "use strict";

    function Util() {}

    (function() {
        Util.isWindow = function(obj) {
            return obj !== null && obj === obj.window;

        Util.isFunction = function(obj) {
            return typeof obj === 'function';
        };

        Util.isObject = function(obj) {
            return typeof obj === 'object';
        };

        Util.isArray = function(obj) {
            return obj instanceof Array;
        };

        Util.isPlainObject = function(obj) {
            return Util.isObject(obj) && !Util.isWindow(obj);
        };

        Util.isString = function(obj) {
            return typeof obj === 'string';
        };

        // 将其他的object统统搞到一个object中去
        // 这个函数不如直接写两个参数看着舒服 target objects，就不用各种slice shift了
        Util.extend = function(target) {
            var deep;
            var args = [].slice.call(arguments, 1);

            if (typeof target === 'boolean') {
                deep = target;
                target = args.shift();
            }

            args.forEach(function(arg) {
               extend(target, arg, deep);
            });

            return target;

            // 这个函数就是把source里面的一层一层往下展开给target，object 和 array会一直展开
            function extend(target, source, deep) {
                for (var key in source) {

Ubuntu 12.04 + Apache2.2.22搭建SPDY服务器

SPDY是Google开发的基于传输控制协议(TCP)的应用层协议，该协议规定在一个SPDY连接内可以有无限个并行请求，服务器可以主动向客户端发起通信向客户端推送数据，通过请求优化、预加载、压缩HTTP 来达到加速的目的。

对用记而言，SPDY是基于SSL加密，它可以让网络访问更安全，用户隐私更加得到保护。对站长而言，SPDY在降低连接数目的同时，还使服务器上每个客户端占用的资源减少，从释放出更多内存和CPU ，让网站的浏览速度提升不少。

SPDY协议已经被Chrome、Firefox、Opera、IE 11以上支持，用户在访问使用SPDY协议加载的网站几乎感觉不到与普通的Https页面访问有何不同，而SPDY带来的页面加载速度提升和服务器性能优化确是有十分重要意义的。

具体的操作步骤如下：

启用Apache2的HTTPS支持

参考 UBUNTU 12.04 下 APACHE 2.2.22 开启 HTTPS

下载Apache2的mod_spdy模块

官网：https://developers.google.com/speed/spdy/mod_spdy/
由于众所周知的原因，本站提供下载（2015-11-6版本）
mod_spdy 64-bit .deb (Debian/Ubuntu)
mod_spdy 32-bit .deb (Debian/Ubuntu)

安装mod_spdy模块（本站是64位系统）

$sudo dpkg -i mod-spdy-*.deb
$sudo apt-get -f install

1 2	$sudo dpkg -i mod-spdy-*.deb $sudo apt-get -f install

重启Apache2

$sudo service apache2 restart

1	$sudo service apache2 restart

验证

目前验证貌似没有起作用啊！目前最新的chrome已经没办法进行验证了，主要是由于HTTP/2已经发布，Google放弃了spdy,转而支持HTTP/2，还是静待新版本的HTTP/2吧。

卸载

$sudo dpkg -r mod-spdy-beta
$sudo dpkg -P mod-spdy-beta

1 2	$sudo dpkg -r mod-spdy-beta $sudo dpkg -P mod-spdy-beta

Ubuntu 12.04安装PHP5的php-curl扩展

在使用WP-Statistics统计插件的时候，提示GeoIP需要 php-curl扩展。搜索了一下，安装方式如下：

$ sudo apt-get install php5-curl

1	$ sudo apt-get install php5-curl

安装完成后，需要重启Apache2

$ sudo service apache2 restart

1	$ sudo service apache2 restart

IScroll的使用-方向键绑定&自定义滚动条样式

之前在webkit上开发一个滚动控件，需要完成的是一段文字，上下键可以滚动，且自定义滚动条。第一想法就是浏览器原生overflow：scroll，且webkit支持自定义滚动条样式：

webkit自定义滚动条样式：

/*定义滚动条高宽及背景 高宽分别对应横竖滚动条的尺寸*/
::-webkit-scrollbar
{
    width: 0.05rem;
    height:1rem;
    background-color: transparent;
}

/*定义滚动条轨道 内阴影+圆角*/
::-webkit-scrollbar-track
{
    background-color: transparent;
}

/*定义滑块 内阴影+圆角*/
::-webkit-scrollbar-thumb
{
    border-radius: 0.1rem;
    /*-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,.3);*/
    background-color: rgba(255,255,255,0.6);
}

/*定义滚动条高宽及背景高宽分别对应横竖滚动条的尺寸*/

::-webkit-scrollbar

{

width: 0.05rem;

height:1rem;

background-color: transparent;

}

/*定义滚动条轨道内阴影+圆角*/

::-webkit-scrollbar-track

{

background-color: transparent;

}

/*定义滑块内阴影+圆角*/

::-webkit-scrollbar-thumb

{

border-radius: 0.1rem;

/*-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,.3);*/

background-color: rgba(255,255,255,0.6);

}

后来换了个引擎，发现其他引擎不支持自定义滚动条，那就满足不了UED的要求了。来同事推荐使用IScroll，用了一下，确实比较方便，与平台无关，可操作的属性还有性能都很理想，记录一下：

首先看官方文档 https://iiunknown.gitbooks.io/iscroll-5-api-cn/content/versions.html

github地址：https://github.com/cubiq/iscroll

demo：http://cubiq.org/dropbox/iscroll4/examples/simple/

直接拿demo中的iscroll.js套到自己的工程上，一个段落就是一个li，new 一下就完事了，滚动拖动也很happy。然后发现，我按上下方向键没有响应。

IScroll按键事件绑定：

查源码看iscroll的事件处理，都在handleEvent函数里面

handleEvent: function (e) {
    var that = this;
    switch(e.type) {
        case START_EV:
        if (!hasTouch && e.button !== 0) return;
        that._start(e);
        break;
        case MOVE_EV: that._move(e); break;
        case END_EV:
        case CANCEL_EV: that._end(e); break;
        case RESIZE_EV: that._resize(); break;
        case WHEEL_EV: that._wheel(e); break;
        case 'mouseout': that._mouseout(e); break;
        case TRNEND_EV: that._transitionEnd(e); break;
    }
}

handleEvent: function (e) {

var that = this;

switch(e.type) {

case START_EV:

if (!hasTouch && e.button !== 0) return;

that._start(e);

break;

case MOVE_EV: that._move(e); break;

case END_EV:

case CANCEL_EV: that._end(e); break;

case RESIZE_EV: that._resize(); break;

case WHEEL_EV: that._wheel(e); break;

case 'mouseout': that._mouseout(e); break;

case TRNEND_EV: that._transitionEnd(e); break;

}

根本就没有keyEvent，看来偷懒是不行的，官方文档看一下，原来iscroll有5个版本，各自平台都是不一样的，demo中这个估计是移动平台用的iscroll-lite版本，移动平台根本不鸟方向键的。

去github上down下来源码，找了找，build目录下，5个版本都有。用最原始的common版本，这个版本的handleEvent就丰富多了：

handleEvent: function (e) {
   switch ( e.type ) {
      case 'touchstart':
      case 'pointerdown':
      case 'MSPointerDown':
      case 'mousedown':
         this._start(e);
         break;
      case 'touchmove':
      case 'pointermove':
      case 'MSPointerMove':
      case 'mousemove':
         this._move(e);
         break;
      case 'touchend':
      case 'pointerup':
      case 'MSPointerUp':
      case 'mouseup':
      case 'touchcancel':
      case 'pointercancel':
      case 'MSPointerCancel':
      case 'mousecancel':
         this._end(e);
         break;
      case 'orientationchange':
      case 'resize':
         this._resize();
         break;
      case 'transitionend':
      case 'webkitTransitionEnd':
      case 'oTransitionEnd':
      case 'MSTransitionEnd':
         this._transitionEnd(e);
         break;
      case 'wheel':
      case 'DOMMouseScroll':
      case 'mousewheel':
         this._wheel(e);
         break;
      case 'keydown':
         this._key(e);
         break;
      case 'click':
         if ( !e._constructed ) {
            e.preventDefault();
            e.stopPropagation();
         }
         break;
   }
}

然后套用上去，可以支持方向键了。中间遇到两个小问题，第一个是按键一直没反应，检查下是z-index太小，keyEvent被上层元素拿走了；第二个是只有在#warpper拿到focus的时候才响应按键，但我用的引擎不支持focus，这个也不难，页面强行绑定handleEvent：

document.addEventListener("keydown", function(evt) {
    if (evt.keyCode === keyCodes.ENTER) {
    } else {
        myScroll && myScroll.handleEvent(evt);
    }
}, false);

document.addEventListener("keydown", function(evt) {

if (evt.keyCode === keyCodes.ENTER) {

} else {

myScroll && myScroll.handleEvent(evt);

}

}, false);

然后整个页面随便按什么键，都可以响应了。接下来就是滚动条样式的问题了，这个也简单，跟着官方文档&样例走就行

http://lab.cubiq.org/iscroll5/demos/styled-scrollbars/

关键步骤有三个：

1.option

myScroll = new IScroll(document.getElementById('wrapper'), {
    keyBindings: true,          // 绑定按键事件
    scrollbars: 'custom',       // 自定义样式
    resizeScrollbars: false     // 是否自动缩放滚动条
});

myScroll = new IScroll(document.getElementById('wrapper'), {

keyBindings: true, // 绑定按键事件

scrollbars: 'custom', // 自定义样式

resizeScrollbars: false // 是否自动缩放滚动条

});

设置了scrollbars: 'custom'，在页面的Elements就可以找到

里面还包含了

第一个是滚动区域，第二个是滚动条。拿到Element就好办了，css给定样式：

.iScrollVerticalScrollbar {
    position: absolute;
    z-index: 9999;
    width: 0.1rem;
    bottom: 2px;
    top: 2px;
    right: 0;
    overflow: hidden;
}

.iScrollIndicator {
    position: absolute;
    width: 0.08rem; height: 0.3rem;
    background: rgba(255,255,255,0.6);
    border-radius: 0.1rem;
}

.iScrollVerticalScrollbar {

position: absolute;

z-index: 9999;

width: 0.1rem;

bottom: 2px;

top: 2px;

right: 0;

overflow: hidden;

}

.iScrollIndicator {

position: absolute;

width: 0.08rem; height: 0.3rem;

background: rgba(255,255,255,0.6);

border-radius: 0.1rem;

}

大功告成！

当然，IScroll不止这点功能，官方文档后面还有无限滚动等高级用法，以后用到再添加。

WordPress使用WP-PostViews实现网站上显示文章的浏览量

WordPress的使用很方便，但是文章的点击浏览量默认是没有的，本文介绍用WP-PostViews实现网站上显示文章的浏览量的功能。效果如下图所示：

安装WP-PostViews插件

在插件界面中安装WP-PostViews插件，并且启用插件。

修改主题文件(Twenty Fourteen)

修改content.php，找到如下代码：

<div class="entry-meta">
	<?php
		if ( 'post' == get_post_type() )
			twentyfourteen_posted_on();

		if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) :
	?>
	<span class="comments-link"><?php comments_popup_link( __( 'Leave a comment', 'twentyfourteen' ), __( '1 Comment', 'twentyfourteen' ), __( '% Comments', 'twentyfourteen' ) ); ?></span>
	<?php
		endif;

		edit_post_link( __( 'Edit', 'twentyfourteen' ), '<span class="edit-link">', '</span>' );
	?>
</div><!-- .entry-meta -->

<?php

if ( 'post' == get_post_type() )

twentyfourteen_posted_on();

if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) :

<?php

endif;

edit_post_link( __( 'Edit', 'twentyfourteen' ), '<span class="edit-link">', '</span>' );

</div>

在后面添加：

<?php 
	/*View Counter for  wp-postviews*/
	if(function_exists('the_views')) { the_views(); } 
?>

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

修改后的结果如下：

<div class="entry-meta">
	<?php
		if ( 'post' == get_post_type() )
			twentyfourteen_posted_on();

		if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) :
	?>
	<span class="comments-link"><?php comments_popup_link( __( 'Leave a comment', 'twentyfourteen' ), __( '1 Comment', 'twentyfourteen' ), __( '% Comments', 'twentyfourteen' ) ); ?></span>
	<?php
		endif;

		edit_post_link( __( 'Edit', 'twentyfourteen' ), '<span class="edit-link">', '</span>' );
	?>
	<?php 
		/*View Counter for  wp-postviews*/
		if(function_exists('the_views')) { the_views(); } 
	?>
</div><!-- .entry-meta -->

<?php

if ( 'post' == get_post_type() )

twentyfourteen_posted_on();

if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) :

<?php

endif;

edit_post_link( __( 'Edit', 'twentyfourteen' ), '<span class="edit-link">', '</span>' );

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

</div>

修改主题文件(Twenty Fifteen)

修改content.php，找到如下代码：

<footer class="entry-footer">
	<?php twentyfifteen_entry_meta(); ?>
	<?php edit_post_link( __( 'Edit', 'twentyfifteen' ), '<span class="edit-link">', '</span>' ); ?>
</footer><!-- .entry-footer -->

<?php twentyfifteen_entry_meta(); ?>

<?php edit_post_link( __( 'Edit', 'twentyfifteen' ), '<span class="edit-link">', '</span>' ); ?>

</footer>

在后面添加：

<?php 
	/*View Counter for  wp-postviews*/
	if(function_exists('the_views')) { the_views(); } 
?>

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

修改后的结果如下：

<footer class="entry-footer">
	<?php twentyfifteen_entry_meta(); ?>
	<?php edit_post_link( __( 'Edit', 'twentyfifteen' ), '<span class="edit-link">', '</span>' ); ?>
	<?php 
		/*View Counter for  wp-postviews*/
		if(function_exists('the_views')) { the_views(); } 
	?>
</footer><!-- .entry-footer -->

<?php twentyfifteen_entry_meta(); ?>

<?php edit_post_link( __( 'Edit', 'twentyfifteen' ), '<span class="edit-link">', '</span>' ); ?>

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

</footer>

LMbench 3.0移植到Android并测试内存带宽

LMbench是个可移植的，用于评价系统综合性能的多平台开源benchmark，能够测试包括文档读写、内存操作、进程创建销毁开销、网络等性能。通过以下步骤操作，即可将LMbench移植到Android上。

下载LMbench源码

下载地址http://sourceforge.net/projects/lmbench/
也可在本站下载

修改LMbench代码

1.解压缩到指定的目录，保证最终的目录如下：

├── lmbench3/

│ ├── src/

│ ├── ACKNOWLEDGEMENTS

│ ├── CHANGES

│ ├── COPYING

│ ├── COPYING-2

│ ├── hbench-REBUTTAL

│ ├── Makefile

│ ├── README

2.修改“src/bench.h”的38行，40行，注释掉“#include <rpc/rpc.h>”，“#include <rpc/types.h>”，然后添加如下定义

#ifndef S_IREAD 
#define S_IREAD S_IRUSR
#endif

#ifndef S_IWRITE
#define S_IWRITE S_IWUSR
#endif

#ifndef S_IREAD

#define S_IREAD S_IRUSR

#endif

#ifndef S_IWRITE

#define S_IWRITE S_IWUSR

#endif

Windows下VirtualBox直接使用物理硬盘作虚拟机磁盘

目前VirtualBox只能用命令行来建立磁盘才可以使用物理硬盘。

我们假定VirtualBox安装在“D:\Program Files\Oracle\VirtualBox”这个目录下面，要在“D:\Users\VirtualBox VMs\Ubuntu\”目录下面生成文件，则执行如下命令：

"D:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands createrawvmdk -filename "D:\Users\VirtualBox VMs\Ubuntu\Ubuntu.vmdk" -rawdisk \\.\PhysicalDrive1

1	"D:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands createrawvmdk -filename "D:\Users\VirtualBox VMs\Ubuntu\Ubuntu.vmdk" -rawdisk \\.\PhysicalDrive1

\\.\PhysicalDrive1 表示机器上的第二块硬盘，\\.\PhysicalDrive0是第一块，\\.\PhysicalDrive2是第三块，以此类推。

在Windows 的磁盘管理中能看到硬盘的分区路径。如下图所示：

然后新建虚拟机，选择"使用已有的虚拟硬盘文件"，找到刚刚创建的 Ubuntu.vmdk 即可。

对于Windows 8.1/10系统，以上的命令需要以管理员启动命令行的方式下启动并执行，否则会报告找不到磁盘。另外启动Virtual Box的时候，同样需要以管理员的身份运行，否则会出现VERR_ACCESS_DENIED错误，如下图所示：
