IOIO, is there a way to call softreset(); from another class?

Question

I have a fragmentactivity and a fragment class; I am trying to set up so that when a user hits a Switch in my fragment class, the oncheckchangedlistener will soft-reset the IOIO-OTG board in order to allow the user to dynamically change a pin on the IOIO from output to input or vice versa.

However I am not sure how to call the ioio_.softReset(); method from outside classes.

Here is some relevent code:

//sets the listener for the mode switches
    for(int i = 0; i<digitalIOModeSwitchArray.length;i++){
        digitalIOModeSwitchArray[i].setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            // TODO Auto-generated method stub

        }
    });
}

NEXT:

@Override
    protected IOIOLooper createIOIOLooper() {
        return new Looper();
    }

    public  IOIOLooper globalLooperRetriever(){
        return l1;
    }

Assuming you already have a looper instance in your activity Here's what you need to do

1. Define an interface

   public interface SoftResetListener
   {
    void softReset();
   }
   

2. Implement that interface in your activity

   public class MainActivity implements SoftResetListener
   {
      public void softReset()
      {
         //replace with your looper instance
         looper.getIOIOBoardInstance().softReset();
      }
   
   }
   

3. Inside your fragment onCheckedChanged()

   @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)     {
       Activity looperActivity= getActivity();
   
       if(looperActivity instanceof SoftResetListener) {
         ((SoftResetListener)looperActivity).softReset();
       }
   
    }
