Android应用中实现系统“分享”接口

简介:
+关注继续查看

在android下各种文件管理器中,我们选择一个文件,点击分享可以看到弹出一些app供我们选择,这个是android系统分享功能,我们做的app也可以出现在这个列表中。


第一步:在Manifest.xml进行配置,比普通的activity中多增加一个Intent过滤器

  1.   <activity  
  2.       android:name="com.example.share.MainActivity"  
  3.       android:label="@string/app_name" >  
  4.       <intent-filter>  
  5.           <action android:name="android.intent.action.MAIN" />  
  6.   
  7.           <category android:name="android.intent.category.LAUNCHER" />  
  8.       </intent-filter>  
  9.         
  10.       <intent-filter>  
  11.             <action android:name="android.intent.action.SEND"/>  
  12.             <category android:name="android.intent.category.DEFAULT"/>  
  13. <!--     指定分享类型,我这边只能分享mp4 -->  
  14.             <data android:mimeType="video/mp4"/>  
  15.  </intent-filter>    
  16.   </activity>  


第二步:用户分享的时候如果选择了我们的app,会跳转到对应的activity,在avtivity中获取文件路径。然后做我们想做的事情

  1. public class MainActivity extends Activity {  
  2.     @Override  
  3.     protected void onCreate(Bundle savedInstanceState) {  
  4.         super.onCreate(savedInstanceState);  
  5.         setContentView(R.layout.activity_main);  
  6.           
  7.         TextView pathTextView=(TextView) findViewById(R.id.path);  
  8.           
  9.             Intent intent = getIntent();  
  10.             String action = intent.getAction();//action  
  11.             String type = intent.getType();//类型  
  12.           
  13.             //类型是mp4类型  
  14.             if (Intent.ACTION_SEND.equals(action) && type != null && "video/mp4".equals(type)) {  
  15.                 Uri uri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);  
  16.                 //如果是媒体类型需要从数据库获取路径  
  17.                 String filePath=getRealPathFromURI(uri);  
  18.                 pathTextView.setText("视频文件路径:"+filePath);  
  19.             }  
  20.     }  
  21.       
  22.     /** 
  23.      * 通过Uri获取文件在本地存储的真实路径 
  24.      */  
  25.     private String getRealPathFromURI(Uri contentUri) {  
  26.         String[] proj = {MediaStore.MediaColumns.DATA};  
  27.         Cursor cursor=getContentResolver().query(contentUri, proj, nullnullnull);  
  28.         if(cursor.moveToNext()){  
  29.             return cursor.getString(cursor.getColumnIndex(MediaStore.MediaColumns.DATA));  
  30.         }  
  31.         cursor.close();  
  32.         return null;  
  33.     }  
  34. }  



如果需要分享多个文件怎么办?

答:修改 Manifest.xml中activity中Intent中action的android:name属性   

  1. <span style="font-size:14px;">            <intent-filter>  
  2.         <!--   支持多个文件分享 -->  
  3.             <action android:name="android.intent.action.SEND_MULTIPLE"/>  
  4.             <category android:name="android.intent.category.DEFAULT"/>  
  5.         <!--     指定分享类型,我这边只能分享mp4 -->  
  6.             <data android:mimeType="video/mp4"/>  
  7.       </intent-filter>  </span>  


效果图如下:

Android 常用 mimeType 表

一、MIME TYPE描述

多用途互联网邮件扩展MIMEMultipurpose Internet Mail Extensions)是一个互联网标准,它扩展了电子邮件标准,使其能够支持非ASCII字符、二进制格式附件等多种格式的邮件消息。

内容类型(Content-Type),这个头部领域用于指定消息的类型。一般以下面的形式出现。[type]/[subtype]

type有下面的形式。

  • Text:用于标准化地表示的文本信息,文本消息可以是多种字符集和或者多种格式的;

  • Multipart:用于连接消息体的多个部分构成一个消息,这些部分可以是不同类型的数据;

  • Application:用于传输应用程序数据或者二进制数据;

  • Message:用于包装一个E-mail消息;

  • Image:用于传输静态图片数据;

  • Audio:用于传输音频或者音声数据;

  • Video:用于传输动态影像数据,可以是与音频编辑在一起的视频数据格式。

subtype用于指定type的详细形式。content-type/subtype配对的集合和与此相关的参数,将随着时间而增长。为了确保这些值在一个有序而且公开的状态下开发,MIME使用Internet Assigned Numbers Authority (IANA)作为中心的注册机制来管理这些值。常用的subtype值如下所示:

  • text/plain(纯文本

  • text/html(HTML文档)

  • application/xhtml+xml(XHTML文档)

  • image/gif(GIF图像)

  • image/jpeg(JPEG图像)【PHP中为:image/pjpeg】

  • image/png(PNG图像)【PHP中为:image/x-png】

  • video/mpeg(MPEG动画)

  • application/octet-stream(任意的二进制数据)

  • application/pdf(PDF文档)

  • application/msword(Microsoft Word文件)

  • message/rfc822(RFC 822形式)

  • multipart/alternative(HTML邮件的HTML形式和纯文本形式,相同内容使用不同形式表示)

  • application/x-www-form-urlencoded(使用HTTP的POST方法提交的表单)

  • multipart/form-data(同上,但主要用于表单提交时伴随文件上传的场合)

  •

初识Serverless函数计算
Serverless 并不是没有服务器,而是开发者不再需要关心服务器。在传统 Serverful 架构下,部署一个应用需要购买服务器,部署操作系统,搭建开发环境,编写代码,构建应用,部署应用,配置负载均衡机制,搭建日志分析与监控系统,应用上线后,继续监控应用的运行情况。而在 Serverless 架构下,开发者只需要关注应用的开发构建和部署,无需关心服务器相关操作与运维,在函数计算架构下,开发者只需要编写业务代码并监控业务运行情况。这将开发者从繁重的运维工作中解放出来,把精力投入到更有意义的业务开发上。
