Contoh Penggunaan Fragment

Salah satu kegunaan Fragment adalah untuk menangani Activity dengan multi konten. Biasanya dikombinasikan dengan ViewPager. Sehingga untuk berpindah-pindah konten tinggal di slide ke kanan atau kekiri. Ok, langsung ke TKP saja.

1. Gunakan android-support-v13.jar

2. Buat dua buah kelas Fragment. FragmentSatu dan FragmentDua.

<pre class="brush:xml"><?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/holo_blue_light" >

	<TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Fragment Satu"
        android:textColor="@android:color/white"
        android:textSize="20sp"/>
</RelativeLayout>

package com.hangga.ikifragment.fragment;

import com.hangga.ikifragment.R;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class FragmentSatu extends Fragment {

	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		View view = inflater.inflate(R.layout.lay_satu, container, false);
		return view;
	}

}

<pre class="brush:xml"><?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"
    android:background="@android:color/holo_orange_dark" >
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Fragment Dua"
        android:textColor="@android:color/white"
        android:textSize="20sp"/>

</LinearLayout>

package com.hangga.ikifragment.fragment;

import com.hangga.ikifragment.R;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class FragmentDua extends Fragment{

	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		View view = inflater.inflate(R.layout.lay_dua, container, false);
		return view;
	}

}

3. Kemudian membuat Fragment Adapter.

package com.hangga.ikifragment.fragment;

import android.support.v13.app.FragmentPagerAdapter; 

public class FragmentAdapter extends FragmentPagerAdapter{

	FragmentSatu fragmentSatu;
	FragmentDua fragmentDua;

	public FragmentAdapter(android.app.FragmentManager fm) {
		super(fm);
	}

	@Override
	public android.app.Fragment getItem(int index) {
		switch (index) {
		case 0:
			fragmentSatu = new FragmentSatu();
			return fragmentSatu;

		case 1:
			fragmentDua = new FragmentDua();
			return fragmentDua;
		}
		return null;
	}

	@Override
	public int getCount() {
		return 2;
	}

}

4. Pasang di Activity menggunakan ViewPager.

<pre class="brush:xml"><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
	<android.support.v4.view.ViewPager
    	android:id="@+id/myPager"
    	android:layout_below="@+id/indicator"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_marginTop="0dp"
        >
    </android.support.v4.view.ViewPager>

</RelativeLayout>

package com.hangga.ikifragment;

import com.hangga.ikifragment.fragment.FragmentAdapter;

import android.os.Bundle;
import android.app.Activity;
import android.support.v4.view.ViewPager;
import android.view.Menu;

public class MainActivity extends Activity {

	ViewPager myPager;
	FragmentAdapter fragmentAdapter;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		myPager = (ViewPager) findViewById(R.id.myPager);
		fragmentAdapter = new FragmentAdapter(getFragmentManager());
		myPager.setAdapter(fragmentAdapter);
		myPager.setCurrentItem(0);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

}
