Membuat Aplikasi Android dengan Navigasi Tab dan Swipe dengan ViewPager

Membuat Aplikasi Android dengan Navigasi Tab dan Swipe dengan ViewPager ini digenerate dari Eclipse ADT versi Build: v21.0.0-531062 dengan SDK versi Jelly Beans. Jadi jangan heran jika project yang anda generate dengan cara yang sama bisa saja hasilnya sedikit berbeda karena Eclipse atau Android Developer Tools yang and gunakan mungkin versinya berbeda dengan yang penulis gunakan.
Project ini menggunakan ViewPager mode Tab dan Fragment, sehingga dalam satu Activity bisa ada beberapa tampilan Fragment Layout. 

Pertama-tama kita buat dahulu project baru dengan Navigasi Tab dan Swipe. Pada langkah menentukan Minimum Required SDK pilih Honeycomb 3.0 karena jika dibawah itu tidak bisa menggunakan Navigasi Tab dan Swipe ini.




Kemudian pada langkah memilih tipe Navigasi pilih Tabs + Swipe.


Kemudian buat desain halaman utama pada file res/layout/activity_main.xml sebagai berikut :

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" />

Kemudian tambahkan file XML Layout baru pada direktory res/layout dengan nama fragment_main.xml sebagai berikut :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Fragment Main" />

    <Button
        android:id="@+id/btnone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="One" />

</LinearLayout>

Kemudian tambahkan lagi file Layout XML baru pada direktory res/layout dengan nama fragment_one.xml sebagai berikut :

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

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Fragment One" />

    <Button
        android:id="@+id/btntwo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Two" />

</LinearLayout>

Kemudian tambahkan lagi file Layout XML baru pada direktory res/layout dengan nama fragment_two.xml sebagai berikut :

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

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Fragment Two" />

    <Button
        android:id="@+id/btnmain"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Main" />

</LinearLayout>
Kemudian buka file MainActivity.java tambahkan kode program berikut ini :
seperti ini :

Untuk file konfigurasi AndroidManifest.xml tidak perlu ada perubahan seperti ini :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.amijaya.android_tabs_swipe_navigation"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="16" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.amijaya.android_tabs_swipe_navigation.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Setelah dijalankan hasilnya sebagai berikut, aplikasi mempunyai Tabs tetapi dapat digeser dengan Swipe juga.


Pada aplikasi tersebut juga sudah diberi contoh bagaimana cara menambahkan button atau komponen lain pada masing-masing tampilan fragment dan bagaimana memberi event dan menambahkan codingnya.


Kode Program selengkapnya dapat didownload disini, jika kesulitan mendownloadnya ini caranya.

Semoga bermanfaat ^_^.
