Android 中的MimeType与MimeTypeMap
Android中MimeType的用途
Intent-Filter中的<data>有一个mimeType . 它的作用是告诉Android系统本Activity可以处理的文件的类型。如设置为 “text/plain”表示可以处理“.txt”文件。
MimeTypeMap类
MimeTypeMap类是专门处理mimeType的类。
类说明以及方法如下:
Class Overview
Two-way map that maps MIME-types to file extensions and vice versa.
Summary
Public Methods |
|||||||||||
getExtensionFromMimeType(String mimeType) Return the registered extension for the given MIME type. |
|||||||||||
static String |
getFileExtensionFromUrl(String url) Returns the file extension or an empty string iff there is no extension. |
||||||||||
getMimeTypeFromExtension(String extension) Return the MIME type for the given extension. |
|||||||||||
static MimeTypeMap |
Get the singleton instance of MimeTypeMap. |
||||||||||
boolean |
hasExtension(String extension) Return true if the given extension has a registered MIME type. |
||||||||||
boolean |
hasMimeType(String mimeType) Return true if the given MIME type has an entry in the map. |
MimeTypeMap类是单例模式的,既没有公有的构造方法。使用getSinglton()方法获得MimeTypeMap对象:
MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton();
示例:
public class MainActivity extends Activity {
private String tag = "MainActivity";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
System.out.println(111);
MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton();
//MimeTypeMap中是否有txt的MimeType
System.out.println(mimeTypeMap.hasExtension("txt"));
System.out.println(mimeTypeMap.hasMimeType("text/html"));
//获得txt文件类型的MimeType
String extension = mimeTypeMap.getMimeTypeFromExtension("txt");
System.out.println(extension);
}
}
从MimeTypeMap源码中可以看到Android2.2支持的文件类型:
