Question

Uri喜欢这样：

com.android.contacts/contacts/lookup/0r431-E08CD8E00524/436

这是我的方式：

Uri entityUri = Uri.withAppendedPath(contactUri, Contacts.Entity.CONTENT_DIRECTORY);
Cursor cursor = resolver.query(entityUri, ContactQuery.COLUMNS, null, null, null);

它总是坠毁！请帮助我，谢谢！

The crash log is below:
 V/ContactTileView(  275):     
 mLookupUricontent://com.android.contacts/contacts/lookup/0r80-29121422/77
 V/ContactTileView(  275):

[275,com.android.contacts,572997,android.database.CursorIndexOutOfBoundsException,Index -1 requested, with a size of 2,AbstractCursor.java,434]

我直接使用查找键：

Cursor cursor = resolver.query(lookupUri, ContactQuery.COLUMNS, null, null, null);

崩溃日志略有不同：

最重要的是，我认为我的要求是我可以通过查询uri获取光标。然后我可以通过此光标从此联系人获取所有信息。非常感谢。

Answer 1

我已经解决了我的问题！这很简单！我的代码没问题，但我必须在调用查询后调用curosr.moveToFist。

Answer 2

我遇到了同样的问题，并且当我不再需要使用游标时调用close方法解决了这个问题。

如何查询单个Uri，然后获取指向Uri项的Cursor对象？
