的URI是這樣的：如何查詢單個Uri，然後獲取指向Uri項目的Cursor對象？
com.android.contacts/contacts/lookup/0r431-E08CD8E00524/436
這是我的方式：
Uri entityUri = Uri.withAppendedPath(contactUri, Contacts.Entity.CONTENT_DIRECTORY);
Cursor cursor = resolver.query(entityUri, ContactQuery.COLUMNS, null, null, null);
它總是崩潰！請幫助我，謝謝！
The crash log is below:
V/ContactTileView( 275):
mLookupUricontent://com.android.contacts/contacts/lookup/0r80-29121422/77
V/ContactTileView( 275):

I/am_crash( 88):

我用直接查找鍵：
Cursor cursor = resolver.query(lookupUri, ContactQuery.COLUMNS, null, null, null);
而崩潰日誌是有點不同：

首先，我認爲我的要求是，我可以得到一個遊標通過查找uri。然後我可以通過這個光標從這個Contact獲得所有的信息。非常感謝。
你的要求說明了什麼？ – 2012-04-12 16:37:18
