c# - Passing data from Activity to ViewModel -

i'm newbie using mvvmcross , have issue. want implement taking photo in activity, native way, don't know how can pass data viewmodel.

there way that?

passing data viewmodel easy. if in activity , given inherits mvxactivity or likes have viewmodel property can access directly it.

there generic versions of these activities, don't have type cast viewmodel property yourself.

so if have:

public class myactivity : mvxactivity<pictureviewmodel> {  } 

then can access viewmodel:

viewmodel.someviewmodelproperty = mydata; 

this mydata object byte array picture data.

mvvmcross have picture taking plugin already, uses built in android camera take pictures with. if add

mvvmcross.plugins.picturechooser 

to both android , core project, can use imvxpicturechoosertask directly in viewmodel without involving else:

public class pictureviewmodel : mvxviewmodel {     private imvxpicturechoosertask _picturetask;     public pictureviewmodel(imvxpicturechoosertask picturetask)     {         _picturetask = picturetask;     }      private byte[] _picturebytes;      // in command:     private void dotakepicture()     {         _picturetask.takepicture(500, 500, stream => {             _picturebytes = readstream(stream);         }, () => {});     } }
