class MyDataBaseHelper extends SQLiteOpenHelper {
public static final String CREATE_USERS= "create table users ("
+ "id integer primary key autoincrement, "
+ "username text, "
+ "password text, "
+ "age integer)";
private Context mContext;
public MyDatabaseHelper(Context context, String name,
SQLiteDatabase.CursorFactory factory, int version){
super(context, name, factory, version);
mContext = context;
}
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(CREATE_USERS);
Toast.makeText(mContext, "数据库创建成功！",
Toast.LENGTH_SHORT).show();
