This is My Database Class. In this I want to insert the data in to the database in the run time. Another class I have edittext while clicking the button the edittext value is inserted in to the database but it is not inserted, how it can be done in this class?
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");
开发者_高级运维db.insert("employee", null, values);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS employees");
onCreate(db);
}
}
