di part pertama kita sudah melakukan persiapan untuk project ini, selanjutnya kita akan membuat class DBHelper di java
pertama buat dulu package data di java kemudian buat class EmployeeDbHelper dan masukan kode di bawah:
package com.giviews.employee.data;
import android.content.Context;
import android.database.DatabaseErrorHandler;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
/**
* Created by asus on 22/10/2017.
*/
public final class EmployeeDbHelper extends SQLiteOpenHelper{
public static final String LOG_TAG = EmployeeDbHelper.class.getSimpleName();
public static final String DATABASE_NAME= "employee.db";
private static final int DATABASE_VERSION = 1;
public EmployeeDbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
//Create String to contains the SQL table
String SQL_CREATE_EMPLOYEES_TABLE = "CREATE TABLE " + EmployeeContract.EmployeeEntry.TABLE_NAME + "("
+ EmployeeContract.EmployeeEntry._ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ EmployeeContract.EmployeeEntry.COLUMN_FIRSTNAME + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_LASTNAME + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_TITLE + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_DEPARTMENT + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_CITY + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_PHONE + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_IMAGE + " BLOB NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_EMAIL + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_EMPLOYEE_GENDER + " INTEGER NOT NULL" + " );";
//EXECUTE THE SQL STATEMENT
db.execSQL(SQL_CREATE_EMPLOYEES_TABLE);
}
@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int oldVersion, int newVersion) {
//on upgrade
}
}
import android.content.Context;
import android.database.DatabaseErrorHandler;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
/**
* Created by asus on 22/10/2017.
*/
public final class EmployeeDbHelper extends SQLiteOpenHelper{
public static final String LOG_TAG = EmployeeDbHelper.class.getSimpleName();
public static final String DATABASE_NAME= "employee.db";
private static final int DATABASE_VERSION = 1;
public EmployeeDbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
//Create String to contains the SQL table
String SQL_CREATE_EMPLOYEES_TABLE = "CREATE TABLE " + EmployeeContract.EmployeeEntry.TABLE_NAME + "("
+ EmployeeContract.EmployeeEntry._ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ EmployeeContract.EmployeeEntry.COLUMN_FIRSTNAME + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_LASTNAME + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_TITLE + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_DEPARTMENT + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_CITY + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_PHONE + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_IMAGE + " BLOB NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_EMAIL + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_EMPLOYEE_GENDER + " INTEGER NOT NULL" + " );";
//EXECUTE THE SQL STATEMENT
db.execSQL(SQL_CREATE_EMPLOYEES_TABLE);
}
@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int oldVersion, int newVersion) {
//on upgrade
}
}
pada kelas DbHelper di atas kita sudah membuat database dan tablenya.
Sekarang kita buat class baru dengan nama EmployeeContract dan masukan kode berikut:
package com.giviews.employee.data;
import android.content.Context;
import android.database.DatabaseErrorHandler;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
/**
* Created by asus on 22/10/2017.
*/
public final class EmployeeDbHelper extends SQLiteOpenHelper{
public static final String LOG_TAG = EmployeeDbHelper.class.getSimpleName();
public static final String DATABASE_NAME = "employee.db";
private static final int DATABASE_VERSION = 1;
public EmployeeDbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
//Create String to contains the SQL table
String SQL_CREATE_EMPLOYEES_TABLE = "CREATE TABLE " + EmployeeContract.EmployeeEntry.TABLE_NAME + "("
+ EmployeeContract.EmployeeEntry._ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ EmployeeContract.EmployeeEntry.COLUMN_FIRSTNAME + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_LASTNAME + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_TITLE + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_DEPARTMENT + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_CITY + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_PHONE + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_IMAGE + " BLOB NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_EMAIL + " TEXT NOT NULL, "
+ EmployeeContract.EmployeeEntry.COLUMN_EMPLOYEE_GENDER + " INTEGER NOT NULL" + " );";
//EXECUTE THE SQL STATEMENT
db.execSQL(SQL_CREATE_EMPLOYEES_TABLE);
}
@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int oldVersion, int newVersion) {
//on upgrade
}
}
kemudian buat lagi class baru dengan nama EmployeeProvider dan masukan kode berikut:
package com.giviews.employee.data;
import android.app.SearchManager;
import android.content.ContentProvider;
import android.content.ContentUris;
import android.content.ContentValues;
import android.content.UriMatcher;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteQueryBuilder;
import android.net.Uri;
import android.util.Log;
import java.util.HashMap;
/**

*/
public class EmployeeProvider extends ContentProvider {
public static final String LOG_TAG = EmployeeProvider.class.getSimpleName();
private static final int EMPLOYEES = 100;
private static final int EMPLOYEE_ID = 101;
private static final int SEARCH_SUGGEST = 102;
private static final HashMap<String, String> SEARCH_SUGGEST_PROJECTION_MAP;
static {
SEARCH_SUGGEST_PROJECTION_MAP = new HashMap<String, String>();
SEARCH_SUGGEST_PROJECTION_MAP.put(EmployeeContract.EmployeeEntry._ID, EmployeeContract.EmployeeEntry._ID);
SEARCH_SUGGEST_PROJECTION_MAP.put(SearchManager.SUGGEST_COLUMN_TEXT_1, EmployeeContract.EmployeeEntry.COLUMN_FIRSTNAME + " AS " + SearchManager.SUGGEST_COLUMN_TEXT_1);
SEARCH_SUGGEST_PROJECTION_MAP.put(SearchManager.SUGGEST_COLUMN_TEXT_2, EmployeeContract.EmployeeEntry.COLUMN_LASTNAME + " AS " + SearchManager.SUGGEST_COLUMN_TEXT_2);
SEARCH_SUGGEST_PROJECTION_MAP.put(SearchManager.SUGGEST_COLUMN_INTENT_DATA_ID, EmployeeContract.EmployeeEntry._ID + " AS " + SearchManager.SUGGEST_COLUMN_INTENT_DATA_ID);
}
private static final UriMatcher sUriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
public static final Uri SEARCH_SUGGEST_URI = Uri.parse("content://" + EmployeeContract.CONTENT_ATHORITY + "/" + EmployeeContract.PATH_EMPLOYEES + "/" + SearchManager.SUGGEST_URI_PATH_QUERY);
static {

public EmployeeProvider(){

pada class EmployeeProvider diatas kita sudah membuat fungsi untuk CRUD nya yaitu fungsi untuk menambahkan data, merubah data, memparsing data dan menghapus data.
setelah kita membuat class-class diatas selanjutnya kita akan membuat desain antarmuka untuk aplikasi kita
pertama kita buat layout activity_employee seperti berikut:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.giviews.employee.EmployeeActivity">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar_setting"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
android:theme="@style/AppTheme.AppBarOverlay" />
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_below="@+id/toolbar_setting">
</ListView>
<!--Empty List-->
<RelativeLayout
android:id="@+id/empty_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true">
<ImageView
android:id="@+id/img"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="@drawable/ic_notifications"
android:layout_centerInParent="true"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Belum Ada Data"
android:gravity="center"
android:layout_below="@+id/img" />
</RelativeLayout>
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:src="@drawable/ic_person_add"/>
</RelativeLayout>
selanjutnya buat layout activity_editor seperti berikut:
<?xml version="1.0" encoding="utf-8"?>
<com.hendraanggrian.widget.RevealFrameLayout
android:id="@+id/revealLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.giviews.employee.EmployeeEditor">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar_setting"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
android:theme="@style/AppTheme.AppBarOverlay" />
<android.support.design.widget.CoordinatorLayout
android:layout_marginTop="56dp"
android:id="@+id/root_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorAccent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="20dp"
android:orientation="vertical">
<ImageView
android:id="@+id/profileImageView"
android:layout_width="200dp"
android:layout_height="200dp"
android:layout_gravity="center"
android:background="@color/colorAccent"
android:scaleType="centerCrop"
android:src="@drawable/ic_account_circle_black"/>
<Button
android:layout_margin="10dp"
android:layout_gravity="center"
android:id="@+id/pickImage"
android:layout_width="90dp"
android:layout_height="wrap_content"
android:text="Select Image" />
<EditText
android:id="@+id/firstName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Fist Name"/>
<EditText
android:id="@+id/lastName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Last Name"/>
<EditText
android:id="@+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Title"/>
<EditText
android:id="@+id/department"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Department"/>
<EditText
android:id="@+id/city"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="City"/>
<EditText
android:id="@+id/phone"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="number"
android:hint="Phone Number"/>
<EditText
android:id="@+id/email"
android:inputType="textEmailAddress"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Email"/>
<Spinner
android:id="@+id/spinner_gender"
android:layout_width="wrap_content"
android:layout_height="32dp"
android:paddingRight="16dp"
android:spinnerMode="dropdown"/>
</LinearLayout>
</ScrollView>
</android.support.design.widget.CoordinatorLayout>
</com.hendraanggrian.widget.RevealFrameLayout>
selanjutnya buat layout list_item untuk menampilkan data listviewnya:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp">
<TextView
android:id="@+id/firstname"
android:textStyle="bold"
android:textSize="17dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/lastname"
android:textStyle="bold"
android:layout_marginLeft="5dp"
android:textSize="17dp"
android:layout_toEndOf="@+id/firstname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="@+id/firstname" />
<TextView
android:id="@+id/titleview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/lastname"/>
</RelativeLayout>
sampai disini dulu part ke2 nya akan kita lanjutkan di part ke 3 memfungsikan layout yang sudah kita buat
