TUTORIAL PEMBUATAN Database(Part 1). PADA ADT BUNDLE ANDROID

1. Buat Project Baru
   
2. Desain interface baru untuk tampilan awal program
   
3. Buat Layout baru dengan nama create data dengan tampilan seperti berikut :
   
   
   4.Buat Class baru pada folder src dengan nama createData,tuliskan coding seperti di bawah ini:
   package com.example.dbandroid;
   
   
   import android.app.Activity;
   import android.os.Bundle;
   import android.view.View;
   import android.view.View.OnClickListener;
   import android.widget.Button;
   import android.widget.EditText;
   import android.widget.Toast;
   
   
   public class createData extends Activity implements OnClickListener {
   private Button Submit;
   private EditText nama,merk,harga;
   private DBDataSource datasource;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
   // TODO Auto-generated method stub
   super.onCreate(savedInstanceState);
   setContentView(R.layout.createdata);
   
   Submit=(Button) findViewById(R.id.btnSubmit);
   Submit.setOnClickListener(this);
   nama=(EditText) findViewById(R.id.txtnama);
   merk=(EditText) findViewById(R.id.txtmerk);
   harga=(EditText) findViewById(R.id.txtharga);
   
   datasource=new DBDataSource(this);
   datasource.open();
   }
   public void onClick(View arg0){
   String nm=null;
   String mk=null;
   String hrg=null;
   
   Barang barang=null;
   
   if(nama.getText()!=null&&merk.getText()!=null && harga.getText()!=null){
   nm=nama.getText().toString();
   mk=merk.getText().toString();
   hrg=harga.getText().toString();
   }
   switch(arg0.getId())
   {
   case R.id.btnSubmit:
   barang=datasource.createBarang(nm,mk,hrg);
   Toast.makeText(this, "masuk Barang\n"+
   "nama"+barang.getNama_barang()+
   "merk"+barang.getMerk_barang()+
   "harga"+barang.getHarga_barang(),
   Toast.LENGTH_LONG).show();
   break;
   }
   
   }
   
   }
   5.Buat class baru dengan nama dbHelper,dan tuliskan coding berikut :
   package com.example.dbandroid;
   
   
   import android.content.Context;
   import android.database.sqlite.SQLiteDatabase;
   import android.database.sqlite.SQLiteOpenHelper;
   import android.util.Log;
   
   
   public class dbHelper extends SQLiteOpenHelper {
   public static final String TABLE_NAME="data_inventory";
   public static final String COLOUMN_ID="_id";
   public static final String COLOUMN_NAME="nama_barang";
   public static final String COLOUMN_MERK="merk_barang";
   public static final String COLOUMN_HARGA="harga_barang";
   private static final String db_name="inventory.db";
   private static final Integer db_version=1;
   
   private static final String db_create="create table"
   +TABLE_NAME+"("
   +COLOUMN_ID+"integer primary key autoincrement,"
   +COLOUMN_NAME+"varchar(50) not null,"
   +COLOUMN_MERK+"varchar(50) not null,"
   +COLOUMN_HARGA+"varchar(50) not null);";
   
   public dbHelper(Context sia){
   super(sia,db_name,null,db_version);
   }
   public void onCreate(SQLiteDatabase db){
   db.execSQL(db_create);
   }
   public void onUpgrade(SQLiteDatabase db,int oldVersion,int newVersion){
   Log.w(dbHelper.class.getName(),"Upgrading database from"+
   oldVersion+"to"+newVersion+"which will destroy all old data");
   db.execSQL("Drop Table If Exists"+TABLE_NAME);
   onCreate(db);
   }
   }
   6.Buat Class baru dengan namaDBDataSource dengan coding seperti berikut:
   package com.example.dbandroid;
   
   
   import android.content.ContentValues;
   import android.content.Context;
   import android.database.SQLException;
   import android.database.sqlite.SQLiteDatabase;
   
   
   public class DBDataSource {
   private SQLiteDatabase database;
   private dbHelper dbHelper;
   
   private String[] allcolomns={
   dbHelper.COLOUMN_ID,
   dbHelper.COLOUMN_NAME,
   dbHelper.COLOUMN_MERK,
   dbHelper.COLOUMN_HARGA
   };
   
   public DBDataSource(Context c){
   dbHelper=new dbHelper(c);
   }
   public void open()throws SQLException{
   database=dbHelper.getWritableDatabase();
   }
   public void close(){
   dbHelper.close();
   }
   public Barang createBarang(String nm,String mk,String hrg){
   ContentValues values=new ContentValues();
   values.put(dbHelper.COLOUMN_NAME, nm);
   values.put(dbHelper.COLOUMN_MERK, mk);
   values.put(dbHelper.COLOUMN_HARGA, hrg);
   
   long insertId=database.insert(dbHelper.TABLE_NAME,null, values);
   Cursor cursor=database.query(distinct, table, columns, selection, selectionArgs, groupBy, having, orderBy, limit, cancellationSignal)
   }
   
   }

TUTORIAL PEMBUATAN CANVAS PADA ADT BUNDLE ANDROID

1. Buat Projek Baru.
   
2. Isikan Kriteria dan desain sesuai yang anda inginkan.
   
3. Ketikan Coding dibawah ini pada layout mainActivity.
   

<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:layout_height="wrap_content"
android:text="@string/hello_world" />


</RelativeLayout>

4. Pilih gambar dan masukan pada folder xxhdpi.
   
5. Isikan coding berikut pada Activity Main pada src.
   

package com.example.canvas2;


import android.os.Bundle;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.view.Menu;
import android.view.View;


public class MainActivity extends Activity {


@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new canvas7(this));
}

static public class canvas7 extends View{
Bitmap gambarkudangambarmu;

public canvas7(Context context){
super(context);
gambarkudangambarmu = BitmapFactory.decodeResource(context.getResources(),R.drawable.aaa);
}
@SuppressLint("DrawAllocation")
protected void onDraw(Canvas canvas){
Paint paint=new Paint();
canvas.drawBitmap(gambarkudangambarmu, 100, 200,paint);
}
}




@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;
}

}

6. Pada coding R.drawable.aaa,”aaa” diganti dengan nama gambar yang anda masukan tadi pada folder xx-hdpi.
   
7. Output :

                if(tabId.equalsIgnoreCase("android")){

                    if(androidFragment==null){

                        /** Create AndroidFragment and adding to fragmenttransaction */

                        ft.add(R.id.realtabcontent,new AndroidFragment(), "android");

                    }else{

                        /** Bring to the front, if already exists in the fragmenttransaction */

                        ft.attach(androidFragment);

                    }

                }else{    /** If current tab is apple */

                    if(appleFragment==null){

                        /** Create AppleFragment and adding to fragmenttransaction */

                        ft.add(R.id.realtabcontent,new AppleFragment(), "apple");

        tSpecAndroid.setIndicator("Tab 1",getResources().getDrawable(R.drawable.android));

        tSpecAndroid.setContent(new DummyTabContent(getBaseContext()));

        tHost.addTab(tSpecAndroid);

        /** Defining tab builder for Apple tab */

        TabHost.TabSpec tSpecApple = tHost.newTabSpec("apple");

        tSpecApple.setIndicator("Tab 2",getResources().getDrawable(R.drawable.apple));

        tSpecApple.setContent(new DummyTabContent(getBaseContext()));

        tHost.addTab(tSpecApple);

    }

}

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@android:style/Theme.Black" >

        <activity

            android:name=".MainActivity"

            android:label="@string/title_activity_main" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
