Android仅从联系人id获取联系人姓名

萨拉姆
我知道答案很简单，但我找不到它
我试试这个：

   Uri uri = Uri.withAppendedPath(
       ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
     contact_id);

   Cursor cursor = managedQuery(uri, null, null, null, null);

   cursor.moveToFirst();

   while(cursor.moveToNext()){
     String name = cursor.getString(cursor.getColumnIndex(
     ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
   }

怎么了？ .

问题出在URI路径中

    Uri uri = Uri.withAppendedPath(
            ContactsContract.Contacts.CONTENT_URI,
            contact_id);

    Cursor cursor = context.getContentResolver().
              query(uri, null, null, null, null);

    cursor.moveToNext();

        contactName = cursor.getString(cursor.
             getColumnIndexOrThrow
                 (ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));

只需移除

cursor.moveToFirst（）谢谢，但无法返回任何结果
