从Widget类连接到数据库
问题描述：
在部件Receiver类扩展 AppWidgetProvider 的时，我想连接到数据库辅助类此Statement获取一些数据，我得到一些错误：
in widget Receiver class that extend AppWidgetProvider when i want to connect to database helper class for fetching some data by this statement i get some error:
public class wigetactivity extends AppWidgetProvider {
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,int[] appWidgetIds) {
final DataBaseHelper myDbHelper = new DataBaseHelper(this);
.
.
.
}
我得到这个错误：构造DataBaseHelper（wigetactivity）未定义
i get this error: The constructor DataBaseHelper(wigetactivity) is undefined
我的数据库辅助类和构造函数的定义是：
my database helper class and constructor definition is:
public class DataBaseHelper extends SQLiteOpenHelper {
public DataBaseHelper(Context context) {
super(context, DB_NAME, null, 1);
this.myContext = context;
}
}
在扩展活动我成功地连接到数据库中的普通班，我怎么能解决呢？
in a regular class that extends Activity i connect successfully to database, How i can fix that?
答
这个（这是不是一个上下文在这种情况下），使用所提供的背景：
Instead of using this (which is not a Context in this case), use the provided context:
final DataBaseHelper myDbHelper = new DataBaseHelper(context);
