(Tutorial Android) Tutorial CRUD with SQLite Database Android

Monday, May 02, 2016

SQLite adalah light weight database yang dapat menyimpan data di device Android. Database ini sudah ditanamkan pada Android OS. SQLite sama halnya dengan DBMS lainnya, yaitu menggunakan query untuk memproses datanya, dan yang membedakannya dengan DBMS lainnya adalah tidak perlu connector untuk terhubung ke database ini karena sudah include di Android.

Pada kali ini saya akan membahas bagaimana menyimpan dan mengakses data di SQLite. Atau biasa kita sebut CRUD ajalah :D

Simak tutorialnya berikut :

Tambahkan library yang diperlukan.


Kita buat desain dulu. Pertama buat layout dengan nama activity_main.xml.
<?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"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context="com.wimso.android_sqlite.MainActivity">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/lvContact"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/add"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:src="@drawable/ic_add_black_24dp"
        android:tint="#FFFFFF"
        app:rippleColor="#F48FB1"
        android:layout_marginRight="@dimen/activity_horizontal_margin"
        android:layout_marginBottom="@dimen/activity_horizontal_margin"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_marginEnd="@dimen/activity_horizontal_margin" />

</RelativeLayout>

Kemudian layout activity_act.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="@dimen/activity_horizontal_margin">

    <EditText
        android:id="@+id/personText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textPersonName"
        android:hint="Insert person name"
        android:ems="10"
        android:layout_marginBottom="@dimen/margin_10" />

    <EditText
        android:id="@+id/phoneText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="phone"
        android:ems="10"
        android:hint="Insert phone number"
        android:layout_marginBottom="@dimen/margin_10" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <Button
            android:id="@+id/btnAdd"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/add"/>

        <Button
            android:id="@+id/btnEdit"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/edit" />

        <Button
            android:id="@+id/btnDelete"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/delete"/>

    </LinearLayout>
</LinearLayout>

Kemudian. Layout list_contact_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="@dimen/margin_10">
    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <ImageView
            android:id="@+id/thumb"
            android:layout_width="60dp"
            android:layout_height="60dp"
            android:src="@mipmap/ic_launcher" />
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="@dimen/margin_10"
            android:orientation="vertical">
            <TextView
                android:id="@+id/name"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="16sp"
                android:text="Small Text"/>
            <TextView
                android:id="@+id/phone"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="14sp"
                android:text="Small Text" />
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

Selanjutnya buat kelas sebagai “constant” dengan nama ContactField.java
package com.wimso.android_sqlite.constant;
/**
 * Created by wim on 4/26/16.
 */
public class ContactField {

    public static final String TABLE_NAME = "contact";
    public static final String COLUMN_ID = "contact_id";
    public static final String COLUMN_NAME = "contact_name";
    public static final String COLUMN_PHONE = "contact_phone";

}

Buat kelas model untuk kontak dengan nama Contact.java
package com.wimso.android_sqlite.model;

import android.os.Parcel;
import android.os.Parcelable;

/**
 * Created by wim on 4/26/16.
 */
public class Contact implements Parcelable {

    private int id;
    private String name;
    private String phone;

    public Contact() {
    }

    protected Contact(Parcel in) {
        this.id = in.readInt();
        this.name = in.readString();
        this.phone = in.readString();
    }
    public static final Parcelable.Creator<Contact> CREATOR = new Parcelable.Creator<Contact>() {
        @Override
        public Contact createFromParcel(Parcel source) {
            return new Contact(source);
        }
        @Override
        public Contact[] newArray(int size) {
            return new Contact[size];
        }
    };

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeInt(this.id);
        dest.writeString(this.name);
        dest.writeString(this.phone);
    }

}

Kemudian buat kelas dengan nama LetterTile.java, jadi kelas ini nanti fungsinya untuk menampilkan thumbail kontak dengan huruf pertama dari nama kontak. Kebayang gag? Yah nanti aja lihat hasilnya.
package com.wimso.android_sqlite.widget;

import android.content.Context;
import android.content.res.Resources;
import android.content.res.TypedArray;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Rect;
import android.graphics.Typeface;
import android.text.TextPaint;
import com.wimso.android_sqlite.R;

/**

 */
public class LetterTile {
    /** The number of available tile colors (see R.array.letter_tile_colors) */
    private static final int NUM_OF_TILE_COLORS = 8;
    /** The {@link TextPaint} used to draw the letter onto the tile */
    private final TextPaint mPaint = new TextPaint();
    /** The bounds that enclose the letter */
    private final Rect mBounds = new Rect();

    private final Canvas mCanvas = new Canvas();
    /** The first char of the name being displayed */
    private final char[] mFirstChar = new char[1];

    private final TypedArray mColors;
    /** The font size used to display the letter */
    private final int mTileLetterFontSize;
    /** The default image to display */
    private final Bitmap mDefaultBitmap;
    /**
     * Constructor for LetterTileProvider
     *
     * @param context The {@link Context} to use
     */
    public LetterTile(Context context) {
        final Resources res = context.getResources();
        mPaint.setTypeface(Typeface.create("sans-serif-light", Typeface.NORMAL));
        mPaint.setColor(Color.WHITE);
        mPaint.setTextAlign(Paint.Align.CENTER);
        mPaint.setAntiAlias(true);
        mColors = res.obtainTypedArray(R.array.letter_tile_colors);
        mTileLetterFontSize = res.getDimensionPixelSize(R.dimen.tile_letter_font_size);
        mDefaultBitmap = BitmapFactory.decodeResource(res, android.R.drawable.sym_def_app_icon);
    }

    /**

     */
    public Bitmap getLetterTile(String displayName, String key, int width, int height) {
        final Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        final char firstChar = displayName.charAt(0);
        final Canvas c = mCanvas;
        c.setBitmap(bitmap);
        c.drawColor(pickColor(key));
        if (isEnglishLetterOrDigit(firstChar)) {
            mFirstChar[0] = Character.toUpperCase(firstChar);
            mPaint.setTextSize(mTileLetterFontSize);
            mPaint.getTextBounds(mFirstChar, 0, 1, mBounds);
            c.drawText(mFirstChar, 0, 1, 0 + width / 2, 0 + height / 2
                    + (mBounds.bottom - mBounds.top) / 2, mPaint);
        } else {
            c.drawBitmap(mDefaultBitmap, 0, 0, null);
        }
        return bitmap;
    }

    /**
     * @param c The char to check
     * @return True if c is in the English alphabet or is a digit,
     *         false otherwise
     */
    private static boolean isEnglishLetterOrDigit(char c) {
        return 'A' <= c && c <= 'Z' || 'a' <= c && c <= 'z' || '0' <= c && c <= '9';
    }

    /**
     * @param key The key used to generate the tile color
     * @return A new or previously chosen color for key used as the
     *         tile background color
     */
    private int pickColor(String key) {
        // String.hashCode() is not supposed to change across java versions, so
        // this should guarantee the same key always maps to the same color
        final int color = Math.abs(key.hashCode()) % NUM_OF_TILE_COLORS;
        try {
            return mColors.getColor(color, Color.BLACK);
        } finally {
            mColors.recycle();
        }
    }
}

Buat sebuah listener yang berfungsi ketika RecyclerView di klik.
package com.wimso.android_sqlite.listener;

import android.view.View;
/**
 * Created by wim on 5/2/16.
 */

public interface RecyclerItemClickListener {
    void onItemClick(int position, View view);
}

Buat adapter dengan nama ContactListAdapter.java
package com.wimso.android_sqlite.adapter;

import android.content.Context;
import android.content.res.Resources;
import android.graphics.Bitmap;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import com.wimso.android_sqlite.R;
import com.wimso.android_sqlite.listener.RecyclerItemClickListener;
import com.wimso.android_sqlite.model.Contact;
import com.wimso.android_sqlite.widget.LetterTile;
import java.util.ArrayList;
import java.util.List;
/**
 * Created by wim on 5/1/16.
 */
public class ContactListAdapter extends RecyclerView.Adapter<ContactListAdapter.ContactHolder>{

    private List<Contact> contactList;
    private Context context;
    private RecyclerItemClickListener recyclerItemClickListener;

    public ContactListAdapter(Context context) {
        this.context = context;
        this.contactList = new ArrayList<>();
    }

    private void add(Contact item) {
        contactList.add(item);
        notifyItemInserted(contactList.size() - 1);
    }

    public void addAll(List<Contact> contactList) {
        for (Contact contact : contactList) {
            add(contact);
        }
    }

    public void remove(Contact item) {
        int position = contactList.indexOf(item);
        if (position > -1) {
            contactList.remove(position);
            notifyItemRemoved(position);
        }
    }

    public void clear() {
        while (getItemCount() > 0) {
            remove(getItem(0));
        }
    }

    public Contact getItem(int position) {
        return contactList.get(position);
    }

    @Override
    public ContactHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_contact_item, parent, false);
        final ContactHolder contactHolder = new ContactHolder(view);
        contactHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int adapterPos = contactHolder.getAdapterPosition();
                if (adapterPos != RecyclerView.NO_POSITION) {
                    if (recyclerItemClickListener != null) {
                        recyclerItemClickListener.onItemClick(adapterPos, contactHolder.itemView);
                    }
                }
            }
        });
        return contactHolder;
    }

    @Override
    public void onBindViewHolder(ContactHolder holder, int position) {
        final Contact contact = contactList.get(position);
        final Resources res = context.getResources();
        final int tileSize = res.getDimensionPixelSize(R.dimen.letter_tile_size);
        LetterTile letterTile = new LetterTile(context);
        Bitmap letterBitmap = letterTile.getLetterTile(contact.getName(),
                String.valueOf(contact.getId()), tileSize, tileSize);
        holder.thumb.setImageBitmap(letterBitmap);
        holder.name.setText(contact.getName());
        holder.phone.setText(contact.getPhone());
    }

    @Override
    public int getItemCount() {
        return contactList.size();
    }

    public void setOnItemClickListener(RecyclerItemClickListener recyclerItemClickListener) {
        this.recyclerItemClickListener = recyclerItemClickListener;
    }

    static class ContactHolder extends RecyclerView.ViewHolder {
        ImageView thumb;
        TextView name;
        TextView phone;
        public ContactHolder(View itemView) {
            super(itemView);
            thumb = (ImageView) itemView.findViewById(R.id.thumb);
            name = (TextView) itemView.findViewById(R.id.name);
            phone = (TextView) itemView.findViewById(R.id.phone);
        }
    }

}

Nah, sekarang kita buat kelas untuk konfiguras database SQLite berserta method-method untuk CRUD. Buat dengan nama SQLiteDB.
package com.wimso.android_sqlite.db;

import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import com.wimso.android_sqlite.constant.ContactField;
import com.wimso.android_sqlite.model.Contact;

/**
 * Created by wim on 4/26/16.
 */
public class SQLiteDB extends SQLiteOpenHelper {

    // If you change the database schema, you must increment the database version.
    public static final int DATABASE_VERSION = 1;
    public static final String DATABASE_NAME = "Contact.db";
    private static final String TEXT_TYPE = " TEXT";
    private static final String COMMA_SEP = ",";
    private static final String SQL_CREATE_ENTRIES =
            "CREATE TABLE " + ContactField.TABLE_NAME + " (" +
                    ContactField.COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," +
                    ContactField.COLUMN_NAME + TEXT_TYPE + COMMA_SEP +
                    ContactField.COLUMN_PHONE + TEXT_TYPE + " )";
    private static final String SQL_DELETE_ENTRIES =
            "DROP TABLE IF EXISTS " + ContactField.TABLE_NAME;

    public SQLiteDB(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL(SQL_CREATE_ENTRIES);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL(SQL_DELETE_ENTRIES);
        onCreate(db);
    }

    public void onDowngrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        onUpgrade(db, oldVersion, newVersion);
    }

    public void create(Contact contact){
        // Gets the data repository in write mode
        SQLiteDatabase db = getWritableDatabase();
        // Create a new map of values, where column names are the keys
        ContentValues values = new ContentValues();
        values.put(ContactField.COLUMN_NAME, contact.getName());
        values.put(ContactField.COLUMN_PHONE, contact.getPhone());
        // Insert the new row, returning the primary key value of the new row
        long newRowId;
        newRowId = db.insert(
                ContactField.TABLE_NAME,
                null,
                values);
    }

    public Cursor retrieve(){
        SQLiteDatabase db = getReadableDatabase();
        // Define a projection that specifies which columns from the database
        // you will actually use after this query.
        String[] projection = {
                ContactField.COLUMN_ID,
                ContactField.COLUMN_NAME,
                ContactField.COLUMN_PHONE };
        // How you want the results sorted in the resulting Cursor
        String sortOrder =
                ContactField.COLUMN_NAME + " ASC";
        Cursor c = db.query(
                ContactField.TABLE_NAME,                    // The table to query
                projection,                                 // The columns to return
                null,                                       // The columns for the WHERE clause
                null,                                       // The values for the WHERE clause
                null,                                       // don't group the rows
                null,                                       // don't filter by row groups
                sortOrder                                   // The sort order
        );
        return c;
    }

    public void update(Contact contact){
        SQLiteDatabase db = getReadableDatabase();
        // New value for one column
        ContentValues values = new ContentValues();
        values.put(ContactField.COLUMN_NAME, contact.getName());
        values.put(ContactField.COLUMN_PHONE, contact.getPhone());
        // Which row to update, based on the ID
        String selection = ContactField.COLUMN_ID + " LIKE ?";
        String[] selectionArgs = { String.valueOf(contact.getId()) };
        int count = db.update(
                ContactField.TABLE_NAME,
                values,
                selection,
                selectionArgs);
    }

    public void delete(int id){
        SQLiteDatabase db = getReadableDatabase();
        // Define 'where' part of query.
        String selection = ContactField.COLUMN_ID + " LIKE ?";
        // Specify arguments in placeholder order.
        String[] selectionArgs = { String.valueOf(id) };
        // Issue SQL statement.
        db.delete(ContactField.TABLE_NAME, selection, selectionArgs);
    }
}

Nah, sekarang kita masuk ke activity. Buat kelas dengan nama MainActivity.java
package com.wimso.android_sqlite;

import android.database.Cursor;
import android.support.design.widget.FloatingActionButton;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

Sebelumnya terimakasih atas tutorialnya gan. Jika saya menggunakan Fragment bukan activity untuk recycleview/list datanya, apakah ada script yg harus dirubah? Mohon bantuannya :)

Balas

gak gan, scriptnya tetap sama,, paling yg dirubah cuma pas itemnya di klik jadi ActActivity.start(getActivity(), contactListAdapter.getItem(position));

Balas
avatar

gan mohon pencerahannya, itu yang bagian mColors = "array" nya error
bagian mTileLetterFontSize = "tile_letter_font_size" nya error,

mColors = res.obtainTypedArray(R.array.letter_tile_colors);

mTileLetterFontSize = res.getDimensionPixelSize(R.dimen.tile_letter_font_size);
