databasehelperクラスにedittextを挿入します。

Question

これは[マイデータベースクラス]です。ここでは、実行時にデータをデータベースに挿入したいと考えています。別のクラス私はボタンをクリックしながらedittext値をデータベースに挿入するが、それは挿入されていない、このクラスではどのように行うことができますか？

public class DatabaseHelper extends SQLiteOpenHelper { 

     public static final String DATABASE_NAME = "employee_directory1"; 

     public DatabaseHelper(Context context) { 
       super(context, DATABASE_NAME, null, 1); 
     } 

     @Override 
     public void onCreate(SQLiteDatabase db) { 
       /* 


public void onCreate(SQLiteDatabase db) { 
       /* 
       * Create the employee table and populate it with sample data. 
       * In step 6, we will move these hardcoded statements to an XML document. 
       */ 
       String sql = "CREATE TABLE IF NOT EXISTS employee (" + 
               "_id INTEGER PRIMARY KEY AUTOINCREMENT, " + 
               "firstName TEXT, " + 
               "lastName TEXT, " + 
               "title TEXT, " + 
               "officePhone TEXT, " + 
               "cellPhone TEXT, " + 
               "email TEXT, " + 
               "managerId INTEGER)"; 
       db.execSQL(sql); 

       ContentValues values = new ContentValues(); 

       values.put("firstName", "John"); 
       values.put("lastName", "Smith"); 
       values.put("title", "CEO"); 
       values.put("officePhone", "617-219-2001"); 
       values.put("cellPhone", "617-456-7890"); 
       values.put("email", "jsmith@email.com"); 
       db.insert("employee", null, values); 



     } 

     @Override 
     public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
       db.execSQL("DROP TABLE IF EXISTS employees"); 
       onCreate(db); 


     } 

}
