This is my small sample to know how to save data in SQLite database on android Apps. I write this with direct sample code. i hope it can understandable

1. SAVE DATA INTO
SQLITE
Android Studio – Case sample in “create user table”

2. Map Directory
• OpenHelper : used for helper database
• DbUser : class user that data will be save in SQLite DB
• StartUpActivity : class that will be sample to
implement save and read user data

3. OpenHelper Class
package com.trans.junifar.transpot.db.sqlite;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
/**
* Created by junifar on 06-Jun-16.
*/
public class OpenHelper extends SQLiteOpenHelper {
private static final String DATABASE_NAME = "MyDB.db";
private static final int DATABASE_VERSION = 1;
private static final String TABLE_CREATE = "CREATE TABLE USER" +
"(" +
"ID INTEGER PRIMARY KEY AUTOINCREMENT," +
"NAME TEXT," +
"PHONE TEXT" +
")";
public OpenHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(TABLE_CREATE);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXIST USER");
}
}

4. DbUser Class
package com.trans.junifar.transpot.db.sqlite;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
/**
* Created by junifar on 06-Jun-16.
*/
public class DbUser {
private final OpenHelper dbHelper;
public static class User {
public String name;
public String phone;
}
private SQLiteDatabase db;
public DbUser(Context c){
dbHelper = new OpenHelper(c);
}
public void open(){
db = dbHelper.getWritableDatabase();
}
public void close(){
db.close();
}
public long insertUser(
String name,
String phone
){
ContentValues newValues = new ContentValues();
newValues.put("name",name);
newValues.put("phone",phone);
return db.insert("USER",null,newValues);
}
public User getUser(String name){
Cursor cur = null;
User usr = new User();
String[] cols = new String[]{"ID","NAME","PHONE"};
String[] param = {name};
cur = db.query("USER",cols,"NAME=?",param,null,null,null);
if (cur.getCount() > 0){
cur.moveToFirst();
usr.name = cur.getString(1);
usr.phone = cur.getString(2);
}
return usr;
}
}

5. StartUpActivity (OnCreate)
public class StartUpActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start_up);
DbUser db = new DbUser(getApplicationContext());
db.open();
db.insertUser("Junifar Hidayat","08567988422");
DbUser.User user = db.getUser("Junifar Hidayat");
AlertDialog ad = new AlertDialog.Builder(this).create();
ad.setMessage("Nama : "+user.name+" Phone : "+user.phone);
ad.show();
}
}

6. THAT’S ALL
Thank you
