Android gallery horizontal scrolling


I have a gallery with images and when scroll horizontally, multiple images are scrolled instead of one.

Below is part of my code:

public View getView(int position, View convertView, ViewGroup parent) {

    View view = convertView;
    if (convertView == null) {
        view = inflater.inflate(resourceid, null);
    }
    synchronized (view) {
        TextView txtTitle = (TextView) view
                .findViewById(R.id.txtCaption);
        ImageList item = getItem(position);

        ImageView ivImage = (ImageView) view.findViewById(R.id.ivImage);
        ivImage.setScaleType(ScaleType.CENTER_INSIDE);
        
        try {
            ivImage.setImageBitmap(getBitmapFromAsset(item.imageUrl));
        }

Solution

  • This solution works perfectly.

    PS: You need to extends a Gallery.

    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
        int kEvent =
                e1.getX() < e2.getX() ? KeyEvent.KEYCODE_DPAD_LEFT : KeyEvent.KEYCODE_DPAD_RIGHT;
        onKeyDown(kEvent, null);
        return true;
    }
