IllegalStateException:从行0获取字段插槽col -1失败

这是我的LogCat:

LogCat引用此行代码01-15 22:13:08.277: ERROR/AndroidRuntime(28747): at com.mohit.geo2do.adapters.TasksAdapter.bindView(TasksAdapter.java:60) 。 这是我的任务适配器的bindView方法:

 @Override public void bindView(View view, Context context, Cursor cursor) { CheckBox checkbox = (CheckBox)view.findViewById(R.id.completed); TextView due_date = (TextView)view.findViewById(R.id.due_date); String title = cursor.getString(cursor.getColumnIndex(Tasks.TITLE)); boolean completed = Util.intToBool(cursor.getInt(cursor.getColumnIndex(Tasks.COMPLETED))); SimpleDateFormat format = new SimpleDateFormat("EEEEEE, MMM dd yyyy hh:mm aa"); long unixTime = Calendar.getInstance().getTimeInMillis(); if (cursor.getLong(cursor.getColumnIndex(Tasks.DUE_DATE)) > 0) { Log.v("TasksAdapter", "Unix time is " + unixTime); unixTime = cursor.getLong(cursor.getColumnIndex(Tasks.DUE_DATE)); Calendar due = Util.timestampToDate(unixTime); due_date.setText(format.format(due.getTime())); } checkbox.setText(title); checkbox.setChecked(completed); due_date.setText("No Deadline"); } 

我已经validation了该列确实存在。 可能是什么问题呢?

更新:
游标来自bindView方法,所以我没有为自己的游标创build查询。 我重新创build数据库,现在我得到这个错误:

我已经validation了列索引是-1:

 01-16 09:46:39.434: VERBOSE/TasksAdapter(32563): The index is -1 

并且due_date列存在:
