通过MIME type的不同用系统含有的程序打开

[java]view plaincopy 
   
 Uri uri = Uri.parse("file://" + filePath);  
 Intent intent = new Intent();  
 intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
 intent.setAction(Intent.ACTION_VIEW);  
 String type = Common.getMIMEType(filePath);  
 intent.setDataAndType(uri, type);  
 if (!type.equals("*/*"))  
 {  
  startActivity(intent);  
 } else  
 {  
  showOpenTypeDialog(filePath);  
 }  

Common.getMIMEType(filePath)代码：

[java]view plaincopy 
   
 /** 
  * 获取文件类型 
  */  
 public static String getMIMEType(String filePath)  
 {  
     String type = "*/*";  
     String fName = filePath;  
       
     int dotIndex = fName.lastIndexOf(".");  
     if (dotIndex < 0)  
     {  
         return type;  
     }  
       
     String end = fName.substring(dotIndex, fName.length()).toLowerCase();  
     if (end == "")  
     {  
         return type;  
     }  
       
     for (int i = 0; i < MIME_MapTable.length; i++)  
     {  
         if (end.equals(MIME_MapTable[i][0]))  
         {  
             type = MIME_MapTable[i][1];  
         }  
     }  
     return type;  
 }  

MIME_MapTable 代码：

[java]view plaincopy 
   
 /**

  */  
 public static final String[][] MIME_MapTable =
