如何刷新的ListView出的CursorAdapter的? [英] How to refresh the ListView out of the CursorAdapter?
问题描述
我有一个ListView在我的活动,这是在的onCreate
设置为
I've got a ListView in my Activity, which is set in the onCreate
by
MyCursorAdapter adapter = new TaskConditsCursorAdapter(this, conditsCursor, taskID, isNewTask);
setListAdapter(adapter);
然后,我做了一些工作的 MyCursorAdapter
。除其他我有一个rowspecific AlertDialog:
Then I do some work in the MyCursorAdapter
. Amongst others I have a rowspecific AlertDialog:
...
builder.setPositiveButton("OK"), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
changeTaskConditBoolValue(taskId, conditId, chosenBoolValue2);
// refresh?
}
});
在 changeTaskConditBoolValue
我想重装我的名单,因为这种方法改变的东西在数据库中,但名单没有更新。 重新查询()
的结果列表是空的。
我怎么能来上一级与适配器
一次是我应该做的,然后它的工作?
After the changeTaskConditBoolValue
I want to reload my List, since this method changed something in the database, but the List didn't update. requery()
results in the list being empty.
How can I come "one level above" to work with the adapter
again and what should I do to it then?
非常感谢!
推荐答案
在 MyCursorAdapter
在所调用的的onClick方法
- 在我的情况下,它是 changeTaskConditBoolValue(...)
我要呼吁:
In the MyCursorAdapter
in the method called by the onClick
- in my case it is changeTaskConditBoolValue(...)
I have to call:
this.changeCursor(db.fetchAllTasks(myParameters));
这得到一个新的光标我的数据库级和替换自己的旧与新的。
This gets a new cursor by my Database-Class and replaces its own old one with the new one.
没有发现其他办法从CursorAdapter的内改变光标。
Found no other way to change the cursor from inside the CursorAdapter.
