1. Buat aplikasi android, dengan klik file new project android, kemudian beri nama projek. disini penulis menggunakan nama "lat", dengan minimal sdk API 8, Target API 18, Compile API 18.
2. Buat Class Java pada direktori src_com.example.lat, dengan cara klik kanan com.example.lat kemudian klik new kemudian klik Class. kelas yang dibuat antara lain App2Activity, Fragment1, Fragment2, Fragment3, Image.
3. Pada Class App2Activity masukan codingan ini :
"package com.example.lat;

8. Pada Class MainActivity isi codingan :
"package com.example.lat;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Button;
import android.view.View;
import android.view.View.OnClickListener;
public class MainActivity extends Activity {
Button button;
Button buttona;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
addListenerOnButton();
}
public void addListenerOnButton() {
final Context context = this;
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, App2Activity.class);
startActivity(intent);
}
});
buttona = (Button) findViewById(R.id.buttoncam);
buttona.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, image.class);
startActivity(intent);
}
});
}
}"
9. Kemudian buat 4 layout dengan cara klik kanan pada directory layout kemudian new kemudian klik android xml file. kemudian buat 4 xml yang terdiri dari gridview, main, main2, maincam.
10. Kemudian isi gridview.xml dengan kodingan :
"
android:layout_width="match_parent"
android:layout_height="match_parent" >
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="@drawable/background"
android:horizontalSpacing="5dp"
android:numColumns="5"
android:stretchMode="columnWidth"
android:verticalSpacing="5dp" >
11. Kemudian isi main.xml dengan kodingan :
"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
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:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/Header"
android:textAppearance="?android:attr/textAppearanceLarge" />
12. Kemudian isikan main2.xml dengan kodingan :
"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/background"
android:id="@+id/mainLayout">
13. Kemudian isikan maincam.xml dengan kodingan :
"
android:layout_height="match_parent" >
android:layout_height="wrap_content" android:layout_alignParentTop="true"
android:orientation="horizontal" android:id="@+id/top">
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" android:layout_below="@id/top">
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="@string/album_name"
/>
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone" />
14. Kemudian pada directory "res" terdapat "androidmanifest.xml" berikan ijin akses kamera dengan kodingan :
"
15. Masih didalam file androidmanifest.xml tambahkan kodingan di antara
"
android:name="com.example.lat.App2Activity" >
android:name="com.example.lat.image" >
16. Disini penulis menggunakan 2 gambar yang digunakan sebagai background dan isi pada fragment yang dimasukan didalam folder res_drawable-hdpi.
17. Kemudian save projek dan jalankan. maka tampilan aplikasi yang dibuat akan seperti gambar dibawah
