Custom scrollview con scroll lock dinámico

Con esta sencilla clase podemos tener un scrollview que deshabilite el scroll dinámicamente en función de un flag

public class MenuScrollView extends ScrollView {

/**

* Flag para controlar el bloqueo del scroll

*/

boolean lock = false;

public boolean isLocked() {

return lock;

}

public void setLock(boolean lock) {

this.lock = lock;

}

public MenuScrollView(Context context, AttributeSet attrs, int i) {

super(context, attrs, i);

this.setVerticalScrollBarEnabled(false);

this.setHorizontalScrollBarEnabled(false);

}

public MenuScrollView(Context context, AttributeSet attrs) {

super(context, attrs);

this.setVerticalScrollBarEnabled(false);

this.setHorizontalScrollBarEnabled(false);

}

public MenuScrollView(Context context) {

super(context);

this.setVerticalScrollBarEnabled(false);

this.setHorizontalScrollBarEnabled(false);

}

/**

* Return true -> no scroll

*/

public boolean onTouchEvent(MotionEvent ev) {

if (lock) {

return true;

} else {

return super.onTouchEvent(ev);

}

}

/**

* Return false -> no scroll

*/

public boolean onInterceptTouchEvent(MotionEvent ev) {

if (lock) {

return false;

} else {

return super.onInterceptTouchEvent(ev);

}

}

}
