android文件关联之mime type

在manifest文件里->activity 添加

这样就把当前程序注册为 可以打开/查看所有类型的文件. 或者要查看jpeg, mimeType要改为: image/jpeg

当在文件管理器里点击任何文件, 系统都会试图去执行你的程序.

一个合法的File Manager在执行Open动作时,应该是发出一个Intent.VIEW Action。所以你的intent-filter应该是这样子的:

  1. 在这当中,data块缺一不可,你必须同时申明android:scheme, android:host, android:pathPattern, 方可令pathPattern正确生效。对于content scheme,将会匹配诸如:content://com.metago.astro.filesystem/sdcard/txt /pg17155.txt 这样的请求,你的Activity将可以有效地打开这样的txt文件。对于file scheme,大致会匹配诸如:file:///sdcard/txt/pg17155.txt这样的请求,并且,如果有必要,你可以加入 android:mimeType限定。

    也就是说,尽管Android SDK的层面上,你不可能了解到哪些mime已经注册,一个自定义的mime如何注册,但对于基础系统(linux os layer)来说,内置的mime type还是存在的,这方面你可以参考Intent SDK文档和Notebook SDK Sample获得一鳞半爪的信息。

    对于你自己想要关联的文件后缀,则应该使用上面的intent-filter组合来完成关联。
    一旦intent-filter关联完成,在Activity的onCreate,onNewIntent中将可通过:
    Intent intent=getIntent();
    Uri uri=(Uri)intent.getData();
    String path=uri.getPath();
    序列获得关联打开文件的绝对路径。

    这样的方法在ASTRO文件管理器中测试通过,并且在另一个测试project中进行了测试和证明机制有效。不过,在Root Explorer,And Explorer中均失败了,原因正在于这几个浏览器并不执行符合Android SDK规范的File Open操作。
    可见,随意性是值得注意的坏招数。

    我们看一下 android 文件的mime类型:
