将菜单项添加到文件资源管理器

Question

我需要将一个菜单项添加到文件资源管理器，但需要是可见的图像和文档（文本文件，pdf，doc等）。

当我使用下面的一段代码时，当我打开文件资源管理器时，菜单项将被添加到所有文件夹中。

ApplicationDescriptor appDesc = ApplicationDescriptor.currentApplicationDescriptor(); 

ApplicationMenuItemRepository amir = ApplicationMenuItemRepository.getInstance(); 

amir.addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_BROWSE, this,appDesc); 
amir.addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_ITEM, this,appDesc); 

按照API我们可以指定MIME类型，使只对特定files.I用下面的代码，但该菜单项只对图像是可见的，而不是针对文档类型菜单项可见。

ApplicationDescriptor appDesc = ApplicationDescriptor.currentApplicationDescriptor(); 

ApplicationMenuItemRepository amir = ApplicationMenuItemRepository.getInstance(); 

amir.addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_BROWSE, this,appDesc,new String("image/*;text/*;application/*")); 
amir.addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_ITEM, this,appDesc,new String("image/*;text/*;application/*")); 

我也尝试了下面的代码，但仍然菜单项只对图像可见，但对文档类型不可见。

ApplicationDescriptor appDesc = ApplicationDescriptor.currentApplicationDescriptor(); 

ApplicationMenuItemRepository amir = ApplicationMenuItemRepository.getInstance(); 

amir.addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_BROWSE, this,appDesc,new String("image/*")); 
amir.addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_ITEM, this,appDesc,new String("image/*")); 
amir.addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_BROWSE, this,appDesc,new String("text/*")); 
amir.addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_ITEM, this,appDesc,new String("text/*")); 

需要帮助来达到要求。

ApplicationMenuItemRepository.getInstance().addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_BROWSE,new BrowserMenuItemClass(0),ApplicationDescriptor.currentApplicationDescriptor(),"image/jpeg");  
    ApplicationMenuItemRepository.getInstance().addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_ITEM,new BrowserMenuItemClass(0),ApplicationDescriptor.currentApplicationDescriptor(),"image/jpeg"); 
    ApplicationMenuItemRepository.getInstance().addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_BROWSE,new BrowserMenuItemClass(0),ApplicationDescriptor.currentApplicationDescriptor(),"image/gif"); 
    ApplicationMenuItemRepository.getInstance().addMenuItem(ApplicationMenuItemRepository.MENUITEM_FILE_EXPLORER_ITEM,new BrowserMenuItemClass(0),ApplicationDescriptor.currentApplicationDescriptor(),"image/gif");
