查詢系統數據庫

Uri uri = CallLog.Calls.CONTENT_URI;

  String[] projection = { CallLog.Calls.DATE, CallLog.Calls.NUMBER,
    CallLog.Calls.TYPE, CallLog.Calls.CACHED_NAME,
    CallLog.Calls._ID }; // 查詢的列
  //全部來電記錄的查詢
  asyncQuery.startQuery(0, null, uri, projection, null, null,
    CallLog.Calls.DEFAULT_SORT_ORDER);

 

 

 

Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; // 聯繫人的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
}; // 查詢的列
asyncQuery.startQuery(0, null, uri, projection, null, null,
      "sort_key COLLATE LOCALIZED asc"); // 按照sort_key升序查詢

 

 

 

//獲取全部信息

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,一個令牌，主要用來標識查詢,保證惟一便可.須要跟onXXXComplete方法傳入的一致。（固然你也能夠不一致，一樣在數據庫的操做結束後會調用對應的onXXXComplete方法 ）

cookie,你想傳給onXXXComplete方法使用的一個對象。(沒有的話傳遞null便可)

Uri uri（進行查詢的通用資源標誌符）:

projection 查詢的列 

selection  限制條件 

selectionArgs 查詢參數

orderBy 排序條件
