Belajar Membuat Aplikasi Android Studi Kasus Proyek Akademi : Layouting

Senin, 15 Juni 2020

Codelab Layouting Proyek Academy

Setelah menyediakan asset-asset yang dibutuhkan, Anda perlu mengubah tampilan dari masing-masing Activity atau Fragment. Ubahlah satu per satu:

activity_course_reader.xml
Bukalah dan ubah ConstraintLayout menjadi FrameLayout:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/frame_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

activity_detail_course.xml
Hapus FloatingActionButton dan tambahkan NestedScrollView:

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.google.android.material.appbar.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <androidx.appcompat.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </com.google.android.material.appbar.AppBarLayout>

    <androidx.core.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <include layout="@layout/content_detail_course" />

    </androidx.core.widget.NestedScrollView>

</androidx.coordinatorlayout.widget.CoordinatorLayout>

Dengan mengubah kode di atas, maka akan terjadi error di kelas DetailCourseActivity. Hapuslah FloatingActionButton pada kelas tersebut, sehingga kode pada kelas DetailCourseActivity menjadi seperti ini:

Kotlin
class DetailCourseActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_detail_course) setSupportActionBar(toolbar) supportActionBar?.setDisplayHomeAsUpEnabled(true) } }
Java
public class DetailCourseActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_detail_course); Toolbar toolbar = findViewById(R.id.toolbar); setSupportActionBar(toolbar); getSupportActionBar().setDisplayHomeAsUpEnabled(true); } }

activity_home.xml
Ubah ConstraintLayout menjadi LinearLayout dan tambahkan TabLayout dan ViewPager:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".ui.home.HomeActivity">

    <com.google.android.material.tabs.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        app:tabTextColor="@android:color/white" />

    <androidx.viewpager.widget.ViewPager
        android:id="@+id/view_pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

content_detail_course.xml
Ubahlah isi layout tersebut menjadi seperti ini:

<?xml version="1.0" encoding="utf-8"?>

</androidx.constraintlayout.widget.ConstraintLayout>

Akan ada eror di bagian tools:listitem="@layout/items_module_list", ini terjadi karena dalam proyek belum ada items_module_list. Anda bisa klik ALT + Enter, kemudian pilih Create layout resource file ‘items_module_list.xml’ dan pilih OK.

    </LinearLayout>
</LinearLayout>

Dengan ini, semua asset layout sudah Anda persiapkan. Selanjutnya apa lagi ya? Tentu menghubungkan semua asset-asset dan komponen yang ada di layout ke Activity dan Fragment. Tetap semangat ya!
