Ошибка при вводе данных в базу данных в android

Question

Я вставляю данные из базы данных с помощью sqlite, но я получаю сообщение об ошибке. Вот мой код и ошибка. Я просто ввел одну запись и хочу отобразить эту запись?

package com.example.database_example; 

public class Information { 

    String name; 
    public Information(String name) { 
     // TODO Auto-generated constructor stub 
     this.name=name; 
    } 

    public String getName() { 
     return name; 
    } 

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

} 

данных Base.java класс

package com.example.database_example; 

import android.os.Bundle; 
import android.app.Activity; 
import android.util.Log; 
import android.view.Menu; 

public class MainActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     Information inf=new Information("naveen"); 
     DataBaseExample dbx=new DataBaseExample(MainActivity.this); 

     if(dbx.insertname(inf)){ 
      Log.v("checkdbx.insertname(inf);", "save ok."); 
     }else{ 
      Log.v("checkdbx.insertname(inf);", "save failed."); 
     } 

    } 



} 
package com.example.database_example; 

import android.content.ContentValues; 
import android.content.Context; 
import android.database.sqlite.SQLiteDatabase; 
import android.database.sqlite.SQLiteDatabase.CursorFactory; 
import android.database.sqlite.SQLiteOpenHelper; 

public class DataBaseExample extends SQLiteOpenHelper{ 

    private static final int DATABASE_VERSION = 1; 

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

    // Contacts table name 
    private static final String TABLE_Name= "Name"; 

    // Contacts Table Columns names 
    private static final String KEY_ID = "id"; 
    private static final String KEY_NAME = "name"; 

    public DataBaseExample(Context context) { 
     super(context, DATABASE_NAME, null, DATABASE_VERSION); 
     // TODO Auto-generated constructor stub 
    } 

    @Override 
    public void onCreate(SQLiteDatabase db) { 
     // TODO Auto-generated method stub 
     String createTable= "CREATE TABLE " + TABLE_Name+"(" 
       + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + KEY_NAME + " TEXT," 
       + ")"; 
     db.execSQL(createTable); 
    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     // TODO Auto-generated method stub 
     db.execSQL("DROP TABLE IF EXISTS " + TABLE_Name); 

      // Create tables again 
      onCreate(db); 
    } 

    public boolean insertname(Information information) { 

     boolean createSuccessful = false; 

     ContentValues values = new ContentValues(); 

     // values.put(KEY_ID, information.getId()); 
     values.put(KEY_NAME, information.getName()); 

     SQLiteDatabase db = this.getWritableDatabase(); 

     createSuccessful = db.insert(TABLE_Name, null, values) > 0; 
     db.close(); 

     return createSuccessful; 
    } 

} 

Вот моя ошибка

Answer 1

Изменить

String createTable= "CREATE TABLE " + TABLE_Name+"(" 
      + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + KEY_NAME + " TEXT," 
      + ")"; 

в

String createTable= "CREATE TABLE " + TABLE_Name+"(" 
      + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + KEY_NAME + " TEXT" 
      + ")"; 

удаление запятой после TEXT

EDIT

Чтобы прочитать все значения из базы данных, вы можете добавить следующий метод в класс DataBaseExample:

private List<Information> getAllItems() 
    List<Information> itemsList = new ArrayList<Information>(); 
    Cursor cursor = null; 
    try { 
     //get all rows 
     cursor = mDatabase.query(TABLE_Name, null, null, null, null, 
       null, null); 
     if (cursor.moveToFirst()) { 
      do { 
       Information c = new Information(); 
       c.setName(cursor.getString(KEY_NAME)); 
       itemsList.add(c); 
      } while (cursor.moveToNext()); 
     } 
    } catch (SQLiteException e) { 
     e.printStackTrace(); 
    } finally { 
     cursor.close(); 
    } 
    return itemsList; 
}
