android CursorAdapter

调用 ContentProvider的query()方法, 抛出异常Caused by: android.database.CursorWindowAllocationException: Cursor window allocation of 2048 kb failed.
如何处理呢

Cursor cursor = null;
try {
cursor = db.query(...
// do some work with the cursor here.
} finally {
// this gets called even if there is an exception somewhere above
if(cursor != null)
cursor.close();
}
检查一下是不是cursor或者数据库没有close关闭造成的溢出
