you cannot disable scrolling of scrollview. need extend scrollview , override ontouchevent method return false when condition matched.

public class lockablescrollview extends scrollview { private boolean mscrollable=true;     public lockablescrollview(context context, attributeset attrs, int defstyle) {         super(context, attrs, defstyle);         // todo auto-generated constructor stub     } 

override required methods , constructors

@override     public boolean ontouchevent(motionevent ev) {         switch (ev.getaction()) {             case motionevent.action_down:                 // if can scroll pass event superclass                 if (mscrollable) return super.ontouchevent(ev); //return mscrollable condition false  /* *write code here implement functionality if image view touched */                     // continue handle touch event if scrolling enabled                     return mscrollable; // mscrollable false @ point     // mscrollable flag may   //use condition                     default:                         return super.ontouchevent(ev);                 }             }     @override   public boolean onintercepttouchevent(motionevent ev) {     switch (ev.getaction()) {          case motionevent.action_down:                  // if can scroll pass event superclass               if (mscrollable) return super.onintercepttouchevent(ev);               // continue handle touch event if scrolling enabled             return mscrollable; // mscrollable false @ point              default:                       return super.onintercepttouchevent(ev);                   }     }
