Dasar SQLlite,Membuat button save,cari,edit,dan delet

Pertama buatlah project baru

Nama Aplikasi : Note PIN

Project Name :scrool

Package Name : com.taufik

Activity name : MainActivity

Layout Name : activity_main

1).Isikan code di pawah ini pada string.xml yang berada pada Folder “res>menu”.

<?xml version="1.0" encoding="utf-8"?>

<string name="hello">Masukkan Nama dan PIN</string>

<string name="app_name">NotePIN</string>

<string name="btnUpdateRow">Update</string>

<string name="ketUpdate">Sebelum mengubah data,pilih dulu baris ke berapa data yang akan diubah</string>

<string name="ketAmbilBaris">Tulis No Urut</string>

<string name="ketDelete">Tulis No Urut</string>

<string name="btnDel">Delete</string>

</resources>

2.Isikan code dibawah ini pada activiry_maim.xml yang berada di folder “res>layout”

3).Isikan code dibawah ini pada MainActivity.java yang berada di folder “src”

package com.taufik;

import java.util.ArrayList;

import android.app.Activity;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.Button;

import android.widget.EditText;

import android.widget.TableLayout;

import android.widget.TableRow;

import android.widget.TextView;

import android.widget.Toast;

public class MainActivity extends Activity {

DatabaseManager dm;

EditText nama, hobi, GetId, updateNama, updateHobi, idDel;

Button addBtn, getIdBtn, updateBtn, delBtn;

TableLayout tabel4data;

// tabel for data

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

dm = new DatabaseManager(this);

setupView();

fungsiBtn();

updateTable();

}

public void setupView() {

tabel4data = (TableLayout) findViewById(R.id.tabel_data);

nama = (EditText) findViewById(R.id.inNama);

hobi = (EditText) findViewById(R.id.inHobi);

updateNama = (EditText) findViewById(R.id.inUpdateNama);

updateHobi = (EditText) findViewById(R.id.inUpdateHobi);

GetId = (EditText) findViewById(R.id.inGetId);

idDel=(EditText)findViewById(R.id.idDelete);

addBtn = (Button) findViewById(R.id.btnAdd);

getIdBtn = (Button) findViewById(R.id.btnGetId);

updateBtn = (Button) findViewById(R.id.btnUpdate);

delBtn = (Button) findViewById(R.id.button1);

}

public void fungsiBtn() {

addBtn.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

simpKamuta();

kosongkanField();

}

});

getIdBtn.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View b) {

ambilBaris();

}

});

updateBtn.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View c) {

updateBaris();

kosongkanField();

}

});

delBtn.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View d) {

// TODO Auto-generated method stub

deleteData();

kosongkanField();

}

});

}

protected void kosongkanField() {

nama.setText("");

hobi.setText("");

updateNama.setText("");

updateHobi.setText("");

GetId.setText("");

idDel.setText("");

}

private void deleteData() {

dm.deleteBaris(Long.parseLong(idDel.getText().toString()));

updateTable();

}

protected void updateBaris() {

dm.updateBaris(Long.parseLong(GetId.getText().toString()), updateNama

.getText().toString(), updateHobi.getText().toString());

updateTable();

}

private void ambilBaris() {

try {

ArrayList<Object> baris;

baris = dm.ambilBaris(Long.parseLong(GetId.getText().toString()));

updateNama.setText((String) baris.get(1));

updateHobi.setText((String) baris.get(2));

} catch (NumberFormatException e) {

e.printStackTrace();

Log.e("eror db", e.toString());

Toast.makeText(getBaseContext(), e.toString(), Toast.LENGTH_LONG)

.show();

}

protected void simpKamuta() {

try {

dm.addRow(nama.getText().toString(), hobi.getText().toString());

updateTable();

} catch (Exception e) {

e.printStackTrace();

Toast.makeText(getBaseContext(), "gagal simpan," + e.toString(),

Toast.LENGTH_LONG).show();

}

protected void updateTable() {

while (tabel4data.getChildCount() > 1) {

tabel4data.removeViewAt(1);

}

ArrayList<ArrayList<Object>> data = dm.ambilSemuaBaris();

for (int posisi = 0; posisi < data.size();

posisi++) {

TableRow tabelBaris = new TableRow(this);

ArrayList<Object> baris = data.get(posisi);

TextView idTxt = new TextView(this);

idTxt.setText(baris.get(0).toString());

tabelBaris.addView(idTxt);

TextView namaTxt = new TextView(this);

namaTxt.setText(baris.get(1).toString());

tabelBaris.addView(namaTxt);

TextView hobiTxt = new TextView(this);

hobiTxt.setText(baris.get(2).toString());

tabelBaris.addView(hobiTxt);

tabel4data.addView(tabelBaris);

}

4.Kemudin buat class baru dengan nama DatabaseManager.java,dan isiskan code di bawah ini

package com.taufik;

import java.util.ArrayList;

import android.content.ContentValues;

import android.content.Context;

import android.database.Cursor;

import android.database.sqlite.SQLiteDatabase;

import android.database.sqlite.SQLiteOpenHelper;

import android.util.Log;

import android.widget.Toast;

public class DatabaseManager {

private static final String ROW_ID = "_id";

private static final String ROW_NAMA = "nama";

private static final String ROW_HOBI = "hobi";

private static final String NAMA_DB = "DatabaseAndroidDua";

private static final String NAMA_TABEL = "hobiku ";

private static final int DB_VERSION = 1;

private static final String CREATE_TABLE = "create table " + NAMA_TABEL

+ " (" + ROW_ID + " integer PRIMARY KEY autoincrement," + ROW_NAMA

+ " text," + ROW_HOBI + " text)";

private final Context context;

private DatabaseOpenHelper dbHelper;

private SQLiteDatabase db;

public DatabaseManager(Context ctx) {

this.context = ctx;

dbHelper = new DatabaseOpenHelper(ctx);

db = dbHelper.getWritableDatabase();

}

private static class DatabaseOpenHelper extends SQLiteOpenHelper {

public DatabaseOpenHelper(Context context) {

super(context, NAMA_DB, null, DB_VERSION);

}

@Override

public void onCreate(SQLiteDatabase db) {

db.execSQL(CREATE_TABLE);

}

@Override

public void onUpgrade(SQLiteDatabase db, int oldVer, int newVer) {

db.execSQL("DROP TABLE IF EXISTS " + NAMA_DB);

onCreate(db);

}

public void close() {

dbHelper.close();

}

public void addRow(String nama, String hobi) {

ContentValues values = new ContentValues();

values.put(ROW_NAMA, nama);

values.put(ROW_HOBI, hobi);

try {

db.insert(NAMA_TABEL, null, values);

} catch (Exception e) {

Log.e("DB ERROR", e.toString());

e.printStackTrace();

}

public ArrayList<ArrayList<Object>> ambilSemuaBaris() {

ArrayList<ArrayList<Object>> dataArray = new ArrayList<ArrayList<Object>>();

Cursor cur;

try {

cur = db.query(NAMA_TABEL, new String[] { ROW_ID, ROW_NAMA,

ROW_HOBI }, null, null, null, null, null);

cur.moveToFirst();

if (!cur.isAfterLast()) {

do {

ArrayList<Object> dataList = new ArrayList<Object>();

dataList.add(cur.getLong(0));

dataList.add(cur.getString(1));

dataList.add(cur.getString(2));

dataArray.add(dataList);

} while (cur.moveToNext());

}

} catch (Exception e) {

e.printStackTrace();

Log.e("DEBE ERROR", e.toString());

Toast.makeText(context, "gagal ambil semua baris:" + e.toString(),

Toast.LENGTH_SHORT).show();

}

return dataArray;

}

public ArrayList<Object> ambilBaris(long rowId) {

ArrayList<Object> arrbaris = new ArrayList<Object>();

Cursor cursor;

try {

cursor = db.query(NAMA_TABEL, new String[] { ROW_ID, ROW_NAMA,

ROW_HOBI }, ROW_ID + "=" + rowId, null, null, null, null,

null);

cursor.moveToFirst();

if (!cursor.isAfterLast()) {

do {

arrbaris.add(cursor.getLong(0));

arrbaris.add(cursor.getString(1));

arrbaris.add(cursor.getString(2));

} while (cursor.moveToNext());

String r = String.valueOf(arrbaris);

Toast.makeText(context, "haha" + r, Toast.LENGTH_SHORT).show();

}

cursor.close();

} catch (Exception e) {

e.printStackTrace();

Log.e("error", e.toString());

Toast.makeText(context, "hhii" + e.toString(), Toast.LENGTH_SHORT)

.show();

}

return arrbaris;

}

public void updateBaris(long rowId, String nama, String hobi) {

ContentValues cv = new ContentValues();

cv.put(ROW_NAMA, nama);

cv.put(ROW_HOBI, hobi);

try {

db.update(NAMA_TABEL, cv, ROW_ID + "=" + rowId, null);

} catch (Exception e) {

e.printStackTrace();

Log.e("Db Error", e.toString());

}

public void deleteBaris(long idBaris) {

try {

db.delete(NAMA_TABEL, ROW_ID + "=" + idBaris, null);

} catch (Exception e) {

e.printStackTrace();

Log.e("Error", e.toString());

}

5). Dan Run lah ,,taraaa lihat hasilnya akan seperti ini
