查询系统数据库

Uri uri = CallLog.Calls.CONTENT_URI;

  String[] projection = { CallLog.Calls.DATE, CallLog.Calls.NUMBER,
    CallLog.Calls.TYPE, CallLog.Calls.CACHED_NAME,
    CallLog.Calls._ID }; // 查询的列
  //全部来电记录的查询
  asyncQuery.startQuery(0, null, uri, projection, null, null,
    CallLog.Calls.DEFAULT_SORT_ORDER);

 

 

 

Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; // 联系人的Uri
String[] projection = {
      ContactsContract.CommonDataKinds.Phone._ID,
      ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
      ContactsContract.CommonDataKinds.Phone.DATA1,
      "sort_key",
      ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
      ContactsContract.CommonDataKinds.Phone.PHOTO_ID,
      ContactsContract.CommonDataKinds.Phone.LOOKUP_KEY
}; // 查询的列
asyncQuery.startQuery(0, null, uri, projection, null, null,
      "sort_key COLLATE LOCALIZED asc"); // 按照sort_key升序查询

 

 

 

//获取全部信息

final String SMS_URI_INBOX = "content://sms/inbox";// 收信箱
String[] projection = new String[] { "_id", "address", "person","body", "date", "type" };
Uri uri = Uri.parse(SMS_URI_INBOX);
asyncQuery.startQuery(0,null,uri,projection,null,null,"date desc");

 

token,一个令牌，主要用来标识查询,保证惟一便可.须要跟onXXXComplete方法传入的一致。（固然你也能够不一致，一样在数据库的操做结束后会调用对应的onXXXComplete方法 ）

cookie,你想传给onXXXComplete方法使用的一个对象。(没有的话传递null便可)

Uri uri（进行查询的通用资源标志符）:

projection 查询的列 

selection  限制条件 

selectionArgs 查询参数

orderBy 排序条件
