        Gallery g = new Gallery(getApplicationContext());
        GalleryLayout.addView(g,new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
            g.setSpacing(15);


        aImageAdapterL = new ImageAdapter(getApplicationContext());
        g.setAdapter(aImageAdapterL);
        g[positionP].setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(@SuppressWarnings("rawtypes") AdapterView parent, View v, int position, long id) {
                Toast.makeText(getBaseContext(), "" + position, Toast.LENGTH_SHORT).show();
            }
