Android - How to store value in Sqlite Database

This post is about "How to create Sqlite Database" and "How to store and retrieve value from SQlite DataBase "

Step - 1 You have to create DataBaseHanler Class .

DatabaseHandler.java

package com.androidhive.androidsqlite;

import java.util.ArrayList;
import java.util.List;

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;

public class DatabaseHandler extends SQLiteOpenHelper {

 // All Static variables
 // Database Version
 private static final int DATABASE_VERSION = 1;

 // Database Name
 private static final String DATABASE_NAME = "MyDatabase";

 // Database table name
 private static final String TABLE_LIST = "MyListItem";

 // Table Columns names
 private static final String KEY_ID = "id";
 private static final String KEY_ListItem = "listitem";

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

 // Creating Tables
 @Override
 public void onCreate(SQLiteDatabase db) {
  String CREATE_LIST_TABLE = "CREATE TABLE " + TABLE_LIST + "(" + KEY_ID
    + " INTEGER," + KEY_ListItem + " TEXT" + ")";

  db.execSQL(CREATE_LIST_TABLE);
 }

 // Upgrading database
 @Override
 public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
  // Drop older table if existed
  db.execSQL("DROP TABLE IF EXISTS " + TABLE_LIST);

  // Create tables again
  onCreate(db);
 }



 void addListItem(ArrayList<String> listItem) {
  SQLiteDatabase db = this.getWritableDatabase();

  ContentValues values = new ContentValues();
  for (int i = 0; i < listItem.size(); i++) {

   Log.e("vlaue inserting==", "" + listItem.get(i));
   values.put(KEY_ListItem, listItem.get(i));
   values.put(KEY_ID, i);
   db.insert(TABLE_LIST, null, values);

  }

  db.close(); // Closing database connection
 }

 Cursor getListItem() {
  String selectQuery = "SELECT  * FROM " + TABLE_LIST;

  SQLiteDatabase db = this.getWritableDatabase();
  Cursor cursor = db.rawQuery(selectQuery, null);

  return cursor;
 }

}

AndroidSQLiteTutorialActivity.java

package com.androidhive.androidsqlite;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.util.Log;

public class AndroidSQLiteTutorialActivity extends Activity {
 /** Called when the activity is first created. */

 ArrayList<String> your_list_arrayArrayList;

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  your_list_arrayArrayList = new ArrayList<String>();

  your_list_arrayArrayList.add("Item1");
  your_list_arrayArrayList.add("Item2");
  your_list_arrayArrayList.add("Item3");
  your_list_arrayArrayList.add("Item4");
  your_list_arrayArrayList.add("Item5");

  DatabaseHandler db = new DatabaseHandler(this);

  db.addListItem(your_list_arrayArrayList);

  Cursor cursor = db.getListItem();

  Log.e("count", "" + cursor.getCount());
  if (cursor != null) {
   cursor.moveToNext();

   do {

    Log.e("value==", "" + cursor.getString(1));
    Log.e("value==", "" + cursor.getString(0));

   } while (cursor.moveToNext());

  }

 }
}

You will find created Database from following steps-
Step 1- Open DDMS
Step 2- Open File Explorer
Step 3- Click on data
Step 4- Again Explore data
Step 5- Now find you package name
Step 6- Click on database
Step 7-  Now you can see your database file's name
Step 8- Export this file in to your PC
