So our app contains five activities now, but they're not all connected.

Aplikasi kita sekarang berisi lima activity, tapi semua tidak terhubung.

When we open our app, we see the main activity, but

Saat kita membuka aplikasi, kita lihat MainActivity, tapi

there's no way to open the Numbers activity from there.

tidak ada cara untuk membuka NumbersActivity dari sini.

So, let's figure out the missing pieces on how to open new activity,

Mari kita pikirkan kepingan yang hilang tentang cara membuka activity baru,

when a category is clicked on.

saat sebuah kategori diklik.

So first, we need to know when a user clicks on a certain category.

Pertama-tama, kita perlu tahu kapan pengguna mengeklik kategori tertentu.

Then we need to learn how to send an intent to open an activity

Lalu kita perlu belajar cara mengirim intent untuk membuka activity

within our app.

dalam aplikasi kita.

So if you remember from the last course, we learned about handling button clicks

Jika Anda ingat kursus terakhir, kita belajar tentang menangani klik tombol

on the Submit button in the Just Java app.

di tombol Kirim dalam aplikasi Just Java.

So, we can apply what we learned there.

Kita bisa menerapkan yang dipelajari di sana.

Now, let's start by making the numbers category work.

Mari mulai dengan menjadikan NumbersCategory berfungsi.

So in the activity_main.xml file.

Dalam file activity_main.xml,

This is where the numbers category is defined in our app an android and

Di sinilah NumbersCategory didefinisikan dalam aplikasi kita, dan di Android,

a view and this is not just buttons.

view apa pun, bukan sekadar tombol.

Remembe,r that buttons are subclass of view.

Ingat, tombol adalah subkelas view.

Any view can be configured to respond to touch input and

View apa pun dapat dikonfigurasi untuk merespons input sentuhan dan

I found it easier to define these as text views.

menurut saya lebih mudah mendefinisikan semua ini sebagai text view.

And then, style the views to look like the design marks.

Lalu, beri style pada view agar tampak seperti maket desain.

Now, I can add on click attribute on this text view X.M.L. element.

Saya bisa menambahkan atribut klik di elemen textView.XML ini

Just like we did on the Submit button from the last course,

seperti yang kita lakukan pada tombol Kirim di kursus terakhir.

I can set the value to be open numbers list.

Saya bisa mengatur nilai menjadi open number list.

Which tells Android to call the function open numbers list,

yang memberi tahu Android untuk memanggil fungsi open number list

when this text view is touched.

saat text view ini disentuh.

Note, that we haven't implemented this function yet.

Perhatikan bahwa kita belum mengimplementasikan fungsi ini.

So, let's head over to the main activity java file and do exactly that.

Mari menuju ke file MainActivity.java dan melakukannya.

In the main activity file, I create this new method called openNumbersList.

Di file MainActivity, saya membuat metode baru bernama OpenNumberList ini.

It needs to be a public method, have a void return value.

Ini harus merupakan metode public, dan memiliki nilai kembali void.

Meaning that it returns nothing and

Artinya, tidak mengembalikan apa-apa dan

I have one input parameter, which will be view.

saya akan memasukkan satu parameter input, yang akan berupa view.

If you're wondering how I know what to write.

Jika Anda bertanya-tanya bagaimana saya bisa tahu apa yang harus ditulis,

Check the documentation for

silakan periksa dokumentasi untuk

the injury on click attribute in the instructor notes below.

atribut onClick Android dalam catatan instruktur di bawah.

All right, so the open numbers list method

Baik, metode openNumberList

will get called when the numbers Category view is clicked on or touched.

akan dipanggil saat numbersCategoryView diklik atau disentuh.

This means that all the lines of code inside this method will get executed.

Ini berarti semua baris kode di dalam metode ini akan dieksekusi.

So, this covers step one of handling the user click.

Jadi, ini menyelesaikan langkah satu dalam menangani klik pengguna.

Now, I'm going to let you figure out step two, which involves figuring out

Sekarang, saya akan mempersilakan Anda memikirkan langkah dua, yang melibatkan

the code that goes inside the open numbers list method.

kode yang ada di dalam metode OpenNumberList.

So you can set an intent to open the numbers activity.

Anda dapat mengatur intent untuk membuka NumbersActivity.

Don't worry about the other categories for now.

Jangan khawatir dengan kategori yang lain sekarang.

All right, so when you're done, you actually look like this.

Baik, setelah Anda selesai, tampilannya seperti ini.

Clicking on the numbers category takes you to the numbers activity, and

Mengeklik NumbersCategory akan membawa Anda ke NumbersActivity, dan

it's expected that the other categories don't work yet.

dapat diperkirakan jika kategori lain belum berfungsi.

That will come in later coding steps.

Itu akan terjadi pada langkah pengodean nanti.

If you need a hint on how to accomplish this,

Jika Anda butuh petunjuk tentang cara melakukan hal ini,

check out the notes below the image quiz.

silakan periksa catatan di bawah kuis gambar.
