Solve gesture-imageview in viewpage can't Drag

[canven]

Don't know good place where i should post this method, Holp to help some people.

In GestureImageViewTouchListener.java file, locate Ontouch methed.

@Override public boolean onTouch(View v, MotionEvent event) {

    Log.i("", "-----onTouch-----" + inZoom);

    if (!inZoom) {

        if (!tapDetector.onTouchEvent(event)) {
            if (event.getPointerCount() == 1 && flingDetector.onTouchEvent(event)) {
                startFling();
            }

            if (event.getAction() == MotionEvent.ACTION_UP) {
                handleUp();
            } else if (event.getAction() == MotionEvent.ACTION_DOWN) {
                stopAnimations();

                last.x = event.getX();
                last.y = event.getY();

                if (boundaryLeft != last.x) {
                    v.getParent().requestDisallowInterceptTouchEvent(true);
                }

                if (imageListener != null) {
                    imageListener.onTouch(last.x, last.y);
                }

                touched = true;
            } else if (event.getAction() == MotionEvent.ACTION_MOVE) {
                if (event.getPointerCount() > 1) {
                    multiTouch = true;
                    if (initialDistance > 0) {

                        pinchVector.set(event);
                        pinchVector.calculateLength();
