onCreate不是数据库类的构造函数。仅当您尝试打开不存在的数据库时才调用它。要打开/创建数据库，您需要添加对以下方法之一的调用：
public class SmartApp extends Activity implements onSharedPreferenceChangeListener { private SmartDBHelper dBHelper; public void onCreate(Bundle savedInstanceState) { //where i am wanting to create the database and tables dBHelper = new SmartDBHelper(getContext()); // open to read and write dBHelper.getWritableDatabase(); // or to read only // dBHelper.getReadableDatabase(); }}它有点大，但是这是我的DatabaseAdapter，您可以看一下：http
