Question

我想创建功能，从我的联系人中读取所有联系人号码，包括sim 1和2联系人，来自电子邮件存储的联系人以及来自电话存储的联系人。但是，在我的应用中，仅显示来自电子邮件存储的联系人。有人请帮助我。非常感谢。

  ContentResolver cr = context.getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, null);
    if (cur.getCount() > 0) {
        while (cur.moveToNext()) {
            String id = cur.getString(
                    cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(
                    cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            String phone="";
            if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                //Query phone here.  Covered next
                Cursor pCur = cr.query(
                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                        null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
                        new String[]{id}, null);
                while (pCur.moveToNext()) {
                    // Do something with phones
                    phone = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                }
                pCur.close();
            }

Answer 2

好吧，您的代码中有一些问题，但是没有一个可以解释您的主要抱怨，您应该在设备上获得所有联系人的所有电话，包括保存在SIM卡上的所有电话。

您的SIM卡上是否保存有未被此代码识别的联系人？您可以在SIM卡上添加带有特殊电话号码（例如1111111）的新联系人，并添加日志以防您的代码在循环中进入该电话吗？

为了改善您的代码并解决其他一些问题，我将进行一些更改：

作为从联系人ID到PhoneContact对象的映射，从ArrayList<PhoneContact>更改为HashMap<Long, PhoneContact>
删除您的selection / selectionArgs / sortOrder变量，无论如何您都不会使用它们
删除//get all phone numbers in this contact if it has multiple numbers下的第二个光标代码，而是检查HashMap以查看CONTACT_ID是否已添加到地图中，如果已添加，则将新数据添加到同一PhoneContact对象中。如果联系人具有多个电话，那么您现有的代码将为同一个联系人创建许多PhoneContact副本。
为循环的每一行添加ACCOUNT_TYPE和ACCOUNT_NAME的日志，这样您就可以在日志中看到数据的来源（Gmail，本地存储，SIM等）
删除您的try / catch，如果您的主循环中发生崩溃，则希望它使应用程序崩溃，这样您就可以理解并解决该问题；如果您遇到崩溃，则可能会解释为什么您没有查看所有数据
