它能查询建议和contactId合成一组的Contacts集合。
注意1：查询结果不包括其本身。
注意2：该查询很耗时。
注意3：这里查询返回的结果也是17列，和Contact一样。具体可以参照《Contact类》
例1：
Uriuri=Contacts.CONTENT_URI.buildUpon()
.appendEncodedPath(String.valueOf(<wbr style="line-height:25px"><span style="color:#339966; line-height:25px">contactId</span><span style="color:#0000ff; line-height:25px">)</span><wbr style="line-height:25px"><span style="color:#0000ff; line-height:25px">)</span><br style="line-height:25px"><span style="color:#0000ff; line-height:25px">.appendPath(Contacts.AggregationSuggestions.CONTENT_DIRECTORY)</span><br style="line-height:25px"><span style="color:#0000ff; line-height:25px">.appendQueryParameter("limit","3")</span><span style="color:#808080; line-height:25px">//这里限定了返回的最大项数</span><br style="line-height:25px"><span style="color:#0000ff; line-height:25px">.build();</span><br style="line-height:25px"><span style="color:#0000ff; line-height:25px">Cursorc=context.getContentResolver().query(uri,</span><br style="line-height:25px"><span style="color:#0000ff; line-height:25px">newString[]{Contacts.DISPLAY_NAME,Contacts._ID,Contacts.LOOKUP_KEY},</span><br style="line-height:25px"><span style="color:#0000ff; line-height:25px">null,null,null);</span></wbr></wbr>
