Catatan: Android sekarang mendukung tampilan daftar horizontal menggunakan RecyclerView, jadi sekarang jawaban ini sudah usang, untuk informasi tentang RecyclerView:
https://developer.android.com/reference/android/support/v7/widget/RecyclerView
Saya telah mengembangkan logika untuk melakukannya tanpa menggunakan pustaka scrollview horizontal eksternal, berikut adalah tampilan horizontal yang saya capai dan saya telah memposting jawaban saya di sini: https://stackoverflow.com/a/33301582/5479863

private int getPixelsToDP(int dp) {

}
Trik yang berfungsi di sini adalah id yang telah saya tetapkan untuk ImageView "imgView.setId (v)" dan setelah itu menerapkan onClickListener untuk itu saya kembali mengambil id tampilan .... Saya juga berkomentar di dalam kode sehingga yang mudah dimengerti, saya harap ini mungkin sangat berguna ... Selamat Coding ... :)
