Membuat Crud Client Server

Baiklah Praktikum kali ini kita akan membuat CRUD Client Server.

sebelumnya kita buat database crud_android. buka localhost/phpmyadmin lalu buat database dan tabelnya. nama tabelnya tabel_biodata. lalu akan menjadi seperti gambar dibawah ini :

kemudian buka folder htdocs kita akan membuat sebuah folder dengan nama crud_android didalam crud_android buat sebuah file dengan nama server.php.


setelah kita buat file php nya sekarang kita akan membuat projectnya dengan nama crud_android. berikut gambar dibawah ini :

sekarang kita akan membuat classnya dengan nama biodata.java. berikut ini :

package jhohannes.com;

public class Biodata extends Koneksi {
String URL = "http://10.0.2.2/crud_android/server.php";
String url = "";
String response = "";

public String tampilBiodata() {
try {
url = URL + "?operasi=view";
System.out.println("URL Tampil Biodata: " + url);
response = call(url);
} catch (Exception e) {
}
return response;
}

public String inserBiodata(String nama, String alamat) {
try {
url = URL + "?operasi=insert&nama=" + nama + "&alamat=" + alamat;
System.out.println("URL Insert Biodata : " + url);
response = call(url);
} catch (Exception e) {
}
return response;
}

public String getBiodataById(int id) {
try {
url = URL + "?operasi=get_biodata_by_id&id=" + id;
System.out.println("URL Insert Biodata : " + url);
response = call(url);
} catch (Exception e) {
}
return response;
}

public String updateBiodata(String id, String nama, String alamat) {
try {
url = URL + "?operasi=update&id=" + id + "&nama=" + nama + "&alamat=" + alamat;
System.out.println("URL Insert Biodata : " + url);
response = call(url);
} catch (Exception e) {
}
return response;
}

public String deleteBiodata(int id) {
try {
url = URL + "?operasi=delete&id=" + id;
System.out.println("URL Insert Biodata : " + url);
response = call(url);
} catch (Exception e) {
}
return response;
}

}

kemudian kita akan membuat class Koneksi.java. berikut ini :

package jhohannes.com;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.net.HttpURLConnection;

import java.net.URL;

import java.net.URLConnection;

public class Koneksi {

public String call(String url) {

int BUFFER_SIZE = 2000;

InputStream in = null;

try {

in = OpenHttpConnection(url);

} catch (IOException e) {

e.printStackTrace();

return "";

}

InputStreamReader isr = new InputStreamReader(in);

int charRead;

String str = "";

char[] inputBuffer = new char[BUFFER_SIZE];

try {

while ((charRead = isr.read(inputBuffer)) > 0) {

String readString = String.copyValueOf(inputBuffer, 0, charRead);

str += readString;

inputBuffer = new char[BUFFER_SIZE];

}

in.close();

} catch (IOException e) {

// Handle Exception

e.printStackTrace();

return "";

}

return str;

}

private InputStream OpenHttpConnection(String url) throws IOException {

InputStream in = null;

int response = -1;

URL url1 = new URL(url);

URLConnection conn = url1.openConnection();

if (!(conn instanceof HttpURLConnection))

throw new IOException("Not An Http Connection");

try {

HttpURLConnection httpconn = (HttpURLConnection) conn;

httpconn.setAllowUserInteraction(false);

httpconn.setInstanceFollowRedirects(true);

httpconn.setRequestMethod("GET");

httpconn.connect();

response = httpconn.getResponseCode();

if (response == HttpURLConnection.HTTP_OK) {

in = httpconn.getInputStream();

}

} catch (Exception e) {

throw new IOException("Error connecting2");

}

return in;

}

}

Setelah itu kita akan membuat class terakhir yaitu class MainActivity. berikut ini :

setelah kita membuat classnya sekarang kita membuat layoutnya. main.xml. berikut ini :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:id="@+id/LinearLayout1"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:layout_gravity="center"

    android:orientation="vertical"

    tools:context=".MainActivity" >

    <Button

        android:id="@+id/buttonTambahBiodata"

        android:layout_width="186dp"

        android:layout_height="wrap_content"

        android:layout_gravity="center"

        android:text="Tambah Biodata" />

    <HorizontalScrollView

        android:id="@+id/horizontalScrollView"

        android:layout_width="match_parent"

        android:layout_height="wrap_content" >

        <ScrollView

            android:id="@+id/verticalScrollView"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content" >

            <TableLayout

                android:id="@+id/tableBiodata"

                android:layout_marginTop="80dp" >

            </TableLayout>

        </ScrollView>

    </HorizontalScrollView>

</LinearLayout>

setelah kita membuat classnya, sekarang kita akan melihat hasilnya :

Membuat Aplikasi Akta

Pada Blog kali ini saya membuat project Akta. dalam project Akta terdiri 5 class dan 4 Layout. sebelum kita membuat project akta, yang pertama kita akan buat yaitu membuat database akta. Nama database : Akta dan terdiri 2 Table yaitu : table daftar_akta dan user.

berikut ini nama-nama class :

• CostumHttpClient.java
• Daftar_akta.java
• Daftar_user.java
• login.java
• menulayanan.java

Nama-nama layaout :

• daftar_akta.xml
• daftar_user.xml
• login.xml
• main.xml

sekarang kita akan membuat class CostumHttpClien.java:

    public void keluar (View theButton)

setelah membuat class daftar_user, sekarang class login.java :

package com.wilis;

import java.util.ArrayList;

import org.apache.http.message.BasicNameValuePair;

               String response = null;

               

               try {

                  

                  response = CustomHttpClient.executeHttpPost("http://10.0.2.2/akta/check.php", postParameters);

                  

                  String res = response.toString();

                  

                  res = res.trim();

                  

                  res = res.replaceAll("\\s+","");

                  

                  status.setText(res);

                  

                  if (res.equals("1")) 

                  {

                  status.setText("Correct Username or Password");

                  berhasil(v); 

                 

                  }

                  else { 

                   status.setText("Sorry!! Wrong Username or Password Entered");

                   

                       }

               }

               

               catch (Exception e) {

                  

                  status.setText(e.toString());

                  

               }

               

            }

            

            });

       

     // penutup buka dari public void onCreate

    }   

        

   

    

    public void daftar (View theButton)

    {

    Intent d = new Intent (this,daftar_user.class);

    startActivity(d);

    }

    

// apabila user berhasil login.

    

    public void berhasil (View theButton)

    {

    Intent s = new Intent (this, menulayanan.class);

    startActivity(s);

    }

    

}

Berikut ini menulayanan :

package com.wilis;

import android.app.AlertDialog;

import android.app.ListActivity;

import android.content.DialogInterface;

import android.content.Intent;

import android.os.Bundle;

//import android.util.Log;

import android.view.View;

import android.widget.ArrayAdapter;

import android.widget.ListView;

import android.widget.Toast;

public class menulayanan extends ListActivity {

/** Called when the activity is first created. */

public void onCreate(Bundle icicle) {

super.onCreate(icicle);

// Create an array of Strings, that will be put to our ListActivity

String[] menulayanan = new String[] { "Petunjuk Pendaftaran", "Syarat-syarat pendaftaran", "Form Pendaftaran Kelahiran", "Call Informasi","Exit"};

//Menset nilai array ke dalam list adapater sehingga data pada array akan dimunculkan dalam list

this.setListAdapter(new ArrayAdapter<String>(this,

android.R.layout.simple_list_item_1,menulayanan));

}

@Override

/**method ini akan mengoveride method onListItemClick yang ada pada class List Activity

* method ini akan dipanggil apabilai ada salah satu item dari list menu yang dipilih

*/

protected void onListItemClick(ListView l, View v, int position, long id) {

super.onListItemClick(l, v, position, id);

// Get the item that was clicked

// Menangkap nilai text yang dklik

Object o = this.getListAdapter().getItem(position);

String pilihan = o.toString();

// Menampilkan hasil pilihan menu dalam bentuk Toast

tampilkanPilihan(pilihan);

}

/**

* Tampilkan Activity sesuai dengan menu yang dipilih

*

*/

protected void tampilkanPilihan(String pilihan) {

try {

//Intent digunakan untuk sebagai pengenal suatu activity

Intent i = null;

if (pilihan.equals("Petunjuk Pendaftaran")) {

i = new Intent(this, login.class);

} else if (pilihan.equals("Syarat-syarat pendaftaran")) {

i = new Intent(this, login.class);

} else if (pilihan.equals("Form Pendaftaran Kelahiran")) {

i = new Intent(this, daftar_akta.class);

} else if (pilihan.equals("Call Informasi")) {

i = new Intent(this, login.class);

} else if (pilihan.equals("Exit")) {

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setMessage("Are you sure want to Exit?")

.setCancelable(false).setPositiveButton("Yes",

new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog,

int id) {

Intent exit = new Intent(

Intent.ACTION_MAIN);

exit.addCategory(Intent.CATEGORY_HOME);

exit

.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

startActivity(exit);

}

}).setNegativeButton("No",

new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog,

int id) {

dialog.cancel();

}

}).show();

} else {

Toast.makeText(this,"Anda Memilih: " + pilihan + " , Actionnya belum dibuat", Toast.LENGTH_LONG).show();

}

startActivity(i);

} catch (Exception e) {

e.printStackTrace();

}

}

}

setelah kita membuat class sekarang kita akan membuat Layout. Berikut ini kita akan membuat main.xml :

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

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

    <TextView

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="@string/hello" />

</LinearLayout>

kemudian kita akan membuat daftar_akta.xml :

sekarang kita akan membuat daftar_user.xml :

layout login.xml :

setelah kita membuat class dan layaoutnya sekarang kita akan menjalankan projectnya. klik kanan pada project lalu Run As -> Android Application.

hasil running :

Sebelum login, terutama mendaftar kemudian kita bisa login kedalam.

Selesai !!!
