Android 应用程序之间内容分享详解(二)


一个Andoird应用程序的重要的地方是他们有相互沟通和整合的能力,一个应用程序可以和另一个应用程序交互,接下来我们来看看Android应用之间的内容分享

当你构建Intent的时候,必须要指定Intent的Action触发,定义Intent的Action例如ACTION_SEND,你大概可以猜到指定Action为ACTION_SEND的Intent的作用是从一个Activity发送数据到另一个Activity,甚至跨越不同的进程,将数据发送给另一个Activity,你需要指定数据和他的类型,系统将识别接收的Activity,并显示他们给用户(假如有多个选择的时候)或者立即启动Activity(只要一个选择的时候)

1.发送文本内容


最直接最常用的是用ACTION_SEND来从一个应用发送文本内容到另一个应用,例如,我们的内置浏览器可以与任何页面当前的URL来共享文字,下面的例子就是共享文本内容

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
//这里是你发送的文本
sendIntent.putExtra(Intent.EXTRA_TEXT, "我用手机测试分享内容");
sendIntent.setType("text/plain");
startActivity(sendIntent);
假如你安装了过滤Action为ACTION_SEND,MIMEtype为“text/plain”的应用程序,这个系统就会启动,假如系统匹配到多个这样子的应用程序,他就会弹出一个Dialog列出所有的应用供用户选择(一个选择器),如下图

可能你觉得上面的代码很简单,我很容易就能写出来,可是你发现了没有,当我们的手机里面没有地图类型的应用程序,你执行startActivity方法,你的程序就会出现Crash(崩溃),所以我们需要先判断下系统是否有这类型的应用程序,判断也很简单

public boolean hasApplication(Intent intent){  
        PackageManager packageManager = getPackageManager();  
        //查询是否有该Intent的Activity  
        List<ResolveInfo> activities = packageManager.queryIntentActivities(intent, 0);  
        //activities里面不为空就有,否则就没有  
        return activities.size() > 0 ? true : false;  
所以我们在startActivity的时候要做上面的判断,这样子我们开发出来的程序才会更加的健壮,少一些Crash用户体验也会更好,假如每次都要判断你师傅会觉得烦?所以我们也可以使用Intent的Intent.createChooser方法

他有如下优点

  • 1.1 即使用户选择了默认的方式,选择器仍然会弹出来
  • 1.2 如果没有匹配到这样的应用程序,系统就会提示消息
  • 1.3 你可以指定选择器Dialog的标题

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "我用手机测试分享内容");
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, "我是弹出框的标题"));


注:某些邮件类应用程序,如Gmail,我们可以使用putExtra(Intent.EXTRA_EMAIL, String[])添加一个字符串数组到Intent中


2.发送二进制内容


二进制内容的共享使用Action为ACTION_SEND,在设置适当的MIME类型,并且添加putExtra(Intent.EXTRA_STREAM, URI),下面是一个常用的共享图片的代码,也可以共享任何类型的二进制内容

Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, uriToImage);
shareIntent.setType("image/jpeg");
startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to)));
主要下面几点

  • 你可以使用MIME type为“ */*” ,他只会匹配处理一般数据流的Activity
  • 接收应用程序需要Uri指定数据的访问权限
  1. 在SD卡的文件,我们使用File file = new File(filePath);Uri.fromFile(file),然后把他传递给Intent
  2. 在应用程序的目录中,openFileOutput的模式为MODE_WORLD_READABLE,然后我们可以使用getFileStreamPath()返回一个File,然后利用Uri.fromFile(file)传递给Intent
  3. 可以扫描图像,视频和音频等媒体文件,添加到系统MediaStore使用SCANFILE()来扫描文件,扫描完成后会调用onScanCompleted()回调方法来返回一个Uri
  4. 图片使用insertImage()方法插入到系统MediaStore也会返回一个图片的Uri

下面是共享图片的例子

Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
File file = new File("mnt/sdcard/share.png");
			
System.out.println(Uri.fromFile(file));
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
shareIntent.setType("image/jpeg");
startActivity(Intent.createChooser(shareIntent, "共享图片"));


选择QQ空间后,图片就显示在那里了,如下图

Android 应用程序之间内容分享详解(一)

我们要共享多个二进制内容利用Action为ACTION_SEND_MULTIPLE,下面是我们共享多张图片

ArrayList<Uri> imageUris = new ArrayList<Uri>();
imageUris.add(imageUri1); // Add your image URIs here
imageUris.add(imageUri2);

Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND_MULTIPLE);
shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUris);
shareIntent.setType("image/*");
startActivity(Intent.createChooser(shareIntent, "Share images to.."));

下面我列出几个常用的MIME type类型

  • 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)
