CRUD MS SQL SERVER ANDROID

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">

        <TextView
            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:textColor="#ffffff"
            android:gravity="center" />

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

            android:hint="PRODUCT NAME"
            android:textSize="20sp"
            android:id="@+id/edtproname" />

        <EditText

            android:textColor="#ffffff"
            android:textColorHint="#ffffff"
            android:textStyle="bold"
            android:background="#5d5d5d"
            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" />

            <Button
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:layout_margin="2dp"

                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 :

                updatePro.execute("");

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

        btndelete.setOnClickListener(new View.OnClickListener(){

        @Override

            }
            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>
