Android权限操作之uses-permission详解

本文实例讲述了Android权限操作之uses-permission。分享给大家供大家参考，具体如下：

我们在安装Android软件的时候，系统会提示该软件所需要的权限，相对于其他系统，android的权限非常多。我们在开发软件的时候，也需要声明相应的权限，比如希望软件能发短信，需要声明软件调用短信的权限，否则软件运行的时候就会报错。

Android的权限在AndroidManifest.xml文件里配置。AndroidManifest文件中有四个标签与permission有关，它们分别是 <permission>、 <permission-group> 、<permission-tree> 和 <uses-permission>。其中最常用的是 <uses-permission>，当我们需要获取某个权限的时候就必须在我们的manifest文件中声明<uses-permission>。

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 </td> 
 <td> <code>&lt;?</code><code>xml</code>&nbsp;<code>version</code><code>=</code><code>"1.0"</code>&nbsp;<code>encoding</code><code>=</code><code>"utf-8"</code><code>?&gt;</code> <code>&lt;</code><code>manifest</code><code>&gt;</code> <code>&nbsp;&nbsp;</code><code>&lt;</code><code>application</code><code>&gt;</code> <code>&nbsp;&nbsp;</code><code>&lt;/</code><code>application</code><code>&gt;</code> <code>&nbsp;&nbsp;</code><code>&lt;</code><code>uses-permission</code>&nbsp;<code>/&gt;</code> <code>&nbsp;&nbsp;</code><code>&lt;</code><code>permission</code>&nbsp;<code>/&gt;</code> <code>&nbsp;&nbsp;</code><code>&lt;</code><code>permission-tree</code>&nbsp;<code>/&gt;</code> <code>&nbsp;&nbsp;</code><code>&lt;</code><code>permission-group</code>&nbsp;<code>/&gt;</code> <code>&nbsp;&nbsp;</code><code>...</code> <code>&lt;/</code><code>manifest</code><code>&gt;</code> </td> 
 </tr> 
 </tbody> 
</table>

<permission>和 <uses-permission>的作用相似，两者之间的不同之处，<uses-permission>是android预定义的权限，<permission>是自己定义的权限。 <permission>用的相对较少，<permission-group>   <permission-tree>这两个标签就更少见了，简单说<permission-group> 就是声明一个标签，该标签代表了一组permissions，而<permission-tree>是为一组permissions声明了一个namespace。后面三个标签具体使用方法后续文章会有介绍。

<permission>定义方法如下：

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 </td> 
 <td> <code>&lt;</code><code>permission</code>&nbsp;<code>android:description</code><code>=</code><code>"string resource"</code> <code>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</code><code>android:icon</code><code>=</code><code>"drawable resource"</code> <code>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</code><code>android:label</code><code>=</code><code>"string resource"</code> <code>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</code><code>android:name</code><code>=</code><code>"string"</code> <code>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</code><code>android:permissionGroup</code><code>=</code><code>"string"</code> <code>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</code><code>android:protectionLevel=["normal" | "dangerous" |</code> <code>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</code><code>"signature" | "signatureOrSystem"] /&gt;</code> </td> 
 </tr> 
 </tbody> 
</table>

上面代码来自官方文档：http://developer.android.com/guide/topics/manifest/permission-element.html。propectionLevel这个属性是必须声明，告诉系统通知用户的应用要求许可,或允许谁认为获得许可的情况下。permissionGroup这个是可选的，与<permission-group>配合使用。label, name和icon用于描述权限。 <permission>的用法后面也会再详细分析。

<uses-permission>是我们用的最多的，官方文档定义方式如下：

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>&lt;</code><code>uses-permission</code>&nbsp;<code>android:name</code><code>=</code><code>"string"</code>&nbsp;<code>/&gt;</code> </td> 
 </tr> 
 </tbody> 
</table>

例如，短信和电话权限的定义：

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 </td> 
 <td> <code>&lt;</code><code>uses-permission</code>&nbsp;<code>android:name</code><code>=</code><code>"android.permission.CALL_PHONE"</code>&nbsp;<code>/&gt;</code> <code>&lt;</code><code>uses-permission</code>&nbsp;<code>android:name</code><code>=</code><code>"android.permission.SEND_SMS"</code><code>/&gt;</code> </td> 
 </tr> 
 </tbody> 
</table>
