Pada tutorial kali ini kita akan membuat Slide Page yang dibuat menggunakan kombinasi antara tab layout dengan view pager. Slide Page ini sudah biasa kita lihat pada aplikasi-aplikasi terkenal seperti WhatsApp, Youtube, google adsense, dan masih banyak lagi.
Untuk membuat Slide Page kita bisa memanfaatkan widget yang disediakan Android Studio yaitu Tab Layout dan View Pager. Tampilan yang nantinya kita buat akan tampak seperti berikut :
Sebelum memulai ada baiknya anda mengetahui struktur class, layout, drawable yang akan kita buat nantinya. Terdapat 4 class yang akan dibuat, satu class utama atau activity dan tiga class fragment yang nantinya akan dipanggil kedalam activity. Layout yang dibutuhkan ada 4 yaitu layout utama (activity_main) dan tiga layout fragment. Didalam drawable kita juga menambahkan ikon back untuk yang akan dipasang pada toolbar aplikasi nantinya, untuk menambahkan icon ini anda bisa menggunakan Vector Asset yang disediakan Android Studio.
Lanjut ke tahap pembuatan project baru :
Sebelum memulai menambahkan dan mengedit file, edit terlebih dahulu dependencies pada file build.grandle (Module.app) dan tambahkan kode dibawah.
Hal ini dimaksudkan untuk mengimport/mendownload library dari android studio sehingga widget Tab Layout dan View Pager dapat digunakan.
dependencies {
...
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
...
}
Buat FragmentSatu.java
public class FragmentSatu extends Fragment {
public FragmentSatu(){
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View view = inflater.inflate(R.layout.fragment_satu, container, false);
return view;
}
}
Buat FragmentDua.java
public class FragmentDua extends Fragment {
public FragmentDua(){
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View view = inflater.inflate(R.layout.fragment_dua, container, false);
return view;
}
}
Buat FragmentTiga.java
public class FragmentTiga extends Fragment {
public FragmentTiga(){
}
@Override
public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View view = inflater.inflate(R.layout.fragment_tiga, container, false);
return view;
}
}
