Pada postingan kali ini, saya akan membahas membuat Insert, Update, Delete dengan android Studio dan Microsoft SQL Server. Biasanya programming dengan android menggunakan middleware untuk komunikasi antara aplikasi dengan database yaitu web service, tapi pada postingan kali ini saya akan memberikan contoh dimana aplikasi android akan langsung konek ke database tanpa perantara middleware (Webservice).

Ok Pertama Buat database di SQL Server dengan nama DBProducttbl, Kemudian buat table dengan nama Producttbl 
Atau bisa copy script berikut untuk membuat table di Sql Server :

CREATE TABLE [dbo].[Producttbl](
       [Id] [int] IDENTITY(1,1) NOT NULL,
       [ProName] [varchar](50) NULL,
       [ProDesc] [varchar](50) NULL,
       [OnDate] [datetime] NULL
)

Ok Selanjutnya Create New Project di Android Studio :

Pertama buat layout seperti gambar berikut :


Atau bisa copy xml file berikut :

<?xml version="1.0" encoding="utf-8"?>
<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:background="#282828"
   
android:orientation="vertical"
   
tools:context="app.app.com.droidsql2.MainActivity">

    <
LinearLayout
       
android:layout_width="match_parent"
       
android:layout_height="wrap_content"
       
android:orientation="vertical"
       
android:layout_alignParentTop="true"
       
android:padding="2dp">

        <

android:layout_width="match_parent"
           
android:layout_height="wrap_content"
           
android:text="ADD PRODUCTS"
           
android:layout_marginTop="7dp"
           
android:typeface="sans"
           
android:textSize="35sp"

android:gravity="center" />

        <

android:padding="10dp"
           
android:inputType="textMultiLine"
           
android:maxLines="3"
           
android:minLines="2"
           
android:layout_gravity="top|left"
           
android:layout_marginTop="5dp"
           
android:id="@+id/edtprodesc" />

        <
LinearLayout
           
android:layout_width="match_parent"
           
android:layout_height="wrap_content"
           
android:weightSum="3"
           
android:layout_marginTop="5dp"
           
android:orientation="horizontal">

            <
Button
               
android:layout_width="0dp"
               
android:layout_height="wrap_content"
               
android:layout_weight="1"
               
android:textColor="#ffffff"
               
android:textSize="20sp"
               
android:layout_margin="2dp"
               
android:padding="7dp"
               
android:layout_marginTop="10dp"
               
android:id="@+id/btnadd"
               
android:text="Add" />

            <

android:textSize="20sp"
               
android:padding="7dp"
               
android:layout_marginTop="10dp"
               
android:id="@+id/btnupdate"
               
android:text="Update" />

            <
Button
               
android:layout_width="0dp"
                
android:layout_height="wrap_content"
               
android:layout_weight="1"
               
android:textColor="#ffffff"
               
android:textSize="20sp"
               
android:layout_margin="2dp"
               
android:padding="7dp"
                
android:layout_marginTop="10dp"
               
android:id="@+id/btndelete"
               
android:text="Delete" />
        </
LinearLayout>

        <
ProgressBar
           
android:layout_width="wrap_content"
           
android:layout_height="wrap_content"
           
android:layout_gravity="center"
           
android:id="@+id/pbbar" />

        <
ListView
           
android:id="@+id/lstproducts"
           
android:layout_width="match_parent"
           
android:layout_height="wrap_content"
            
android:divider="#808080"
           
android:layout_marginTop="5dp"
           
android:dividerHeight="1dp"
           
android:padding="5dp">

        </
ListView>
    </
LinearLayout>
</
RelativeLayout>


Tambahkan satu layout baru dengan nama lsttemplate.xml
kemudian masukkan code xml berikut :

<?xml version="1.0" encoding="utf-8"?>
  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:weightSum="5"
    android:padding="5dp"
    android:layout_marginTop="2dp">
  

    <TextView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:textColor="#ffffff"
        android:layout_weight="1"
        android:textSize="15sp"
        android:text="1"
        android:id="@+id/lblproid"/>
  

    <TextView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="4"
        android:textColor="#ffffff"
        android:textSize="15sp"
        android:text="MOTOROLA"
        android:id="@+id/lblproname"/>
  

    <TextView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0"
        android:textColor="#ffffff"
        android:textSize="0sp"
        android:text="MOTOROLA"
        android:id="@+id/lblprodesc"/>

</LinearLayout>



Selanjutnya tambahkan class baru dengan nama : ConnectionClass.java 
Berikut detail source code dari ConnectionClass.java

package app.app.com.droidsql2;

  

  import android.annotation.SuppressLint;

  import android.os.StrictMode;

  import android.util.Log;

  

  import java.sql.Connection;

  import java.sql.DriverManager;

  import java.sql.SQLException;

  

  /**

 * Created by IT on 2/17/2017.

 */

  public class ConnectionClass {

    String ip = "192.168.88.197";

    String classs = "net.sourceforge.jtds.jdbc.Driver";

    String db = "ERP120";

    String un = "sa";

    String password = "Admin123456kr";

  

    @SuppressLint("NewApi")

    public Connection CONN() {

        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()

                .permitAll().build();

        StrictMode.setThreadPolicy(policy);

        Connection conn = null;

        String ConnURL = null;

        try {

  

            Class.forName(classs);

            ConnURL = "jdbc:jtds:sqlserver://" + ip + ";"

                    + "databaseName=" + db + ";user=" + un + ";password="

                    + password + ";";

            conn = DriverManager.getConnection(ConnURL);

        } catch (SQLException se) {

            Log.e("ERRO", se.getMessage());

        } catch (ClassNotFoundException e) {

            Log.e("ERRO", e.getMessage());

        } catch (Exception e) {

            Log.e("ERRO", e.getMessage());

        }

        return conn;

    }

}


Kemudian di MainActivity.java tuliskan source code seperti berikut : 

package app.app.com.droidsql2;

        });

        btnupdate.setOnClickListener(new View.OnClickListener(){

                updatePro.execute("");

                edtproname.setText("");
                edtprodesc.setText("");
            }
        });

        btndelete.setOnClickListener(new View.OnClickListener(){

            }
            return z;
        }
    }

Terakhir rubah Manifest menjadi seperti berikut :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"    
package="app.app.com.droidsql2">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

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

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