android - get value from SpinnerWheel -

i'm trying value android spinnerwheel. there few post in giving answer , not 1 post shows true information. found 1 link bit descriptive still didn't have result wanted. if can show me how can value , set in textview, great

my code    public class mainactivity extends activity {  	textview textvalue;  	string value;    	@override  	protected void oncreate(bundle savedinstancestate) {  		super.oncreate(savedinstancestate);  		setcontentview(r.layout.activity_main);  		  		textvalue = (textview)findviewbyid(r.id.textvalue);  		  		 final abstractwheel mins = (abstractwheel) findviewbyid(r.id.mins);  	        numericwheeladapter minadapter = new numericwheeladapter(this, 0, 59, "%02d");  	        minadapter.setitemresource(r.layout.wheel_text_centered_dark_back);  	        minadapter.setitemtextresource(r.id.text);  	        mins.setviewadapter(minadapter);  	          	          	          	        //onwheelchangedlistener listener = null;  			//mins.addchanginglistener(listener);  	          			  	}  	  	 private onwheelchangedlistener changedlistener = new onwheelchangedlistener() {  	        public void onchanged(abstractwheel wheel, int oldvalue, int newvalue) {  	        	string value = string.valueof(newvalue);  	        	textvalue.settext(value);  	        }  	    };  	  	  	  	  	    	  }

.

the thing see is, haven´t added listener wheel, because had commented out:

     //mins.addchanginglistener(listener); 

it must be:

     mins.addchanginglistener(changedlistener);
