从android&；转换为JSON

如何从这些信息中获取所有信息，如主要和次要手机号码、电子邮件、传真、图像以及制作json数组

---

目前我可以获得primaryContact和一个姓名。我可以在自定义列表视图中显示它们，就像whats应用程序一样。

您可以使用类似的内容阅读联系人，我在我的应用程序中使用了它，它正在工作：

Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);

if（光标！=null）{
如果（cursor.getCount（）>0）{

String id=cursor.getString（cursor.getColumnIndex（ContactsContract.CommonDataTypes.Phone.CONTACT_id））；
字符串名称=cursor.getString（cursor.getColumnIndex（ContactsContract.CommonDataTypes.Phone.DISPLAY_name））；
String number=cursor.getString（cursor.getColumnIndex（ContactsContract.CommonDataTypes.Phone.number））；
}
}
}

下面是一些在服务器上发布数据的示例：

希望这些能对您有所帮助。

您可以使用以下简单代码创建一个json对象：目前，我正在获取所有联系人的所有电话号码、电子邮件、组织详细信息和标题

注意：您需要阅读联系人权限

Kotlin中的代码：

private fun getContacts(): JsonArray {

    val resolver: ContentResolver = contentResolver
    val cursor = resolver.query(
        ContactsContract.Contacts.CONTENT_URI, null, null, null,
        null
    )
    val mainJsonArray: JsonArray = JsonArray()
    if (cursor!!.count > 0) {
        while (cursor.moveToNext()) {
            val personJsonObj: JsonObject = JsonObject()
            val id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID))
            val name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME))
            //val phoneNumber = (cursor.getString( cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER) )).toInt()
            personJsonObj.addProperty("NAME", name.replace("\\", "\\\\").replace("'", "\\'").replace("\"", "\\\""))

            val orgCursor = getContentResolver().query(
                ContactsContract.Data.CONTENT_URI, null,
                ContactsContract.Data.CONTACT_ID + "=?", arrayOf(id), null
            )

            val phoneJsonArray = JsonArray()
            val emailJsonArray = JsonArray()

            if (orgCursor!!.count > 0) {
                while (orgCursor.moveToNext()) {
                    if (orgCursor!!.getString(orgCursor.getColumnIndex(ContactsContract.Data.MIMETYPE)).equals(
                            ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE
                        )

                        val companyName = orgCursor.getString(orgCursor.getColumnIndex(ContactsContract.Data.DATA1))
                        val designation = orgCursor.getString(orgCursor.getColumnIndex(ContactsContract.Data.DATA4))
                        personJsonObj.addProperty(

                            designation.replace("\\", "\\\\").replace("'", "\\'").replace("\"", "\\\"")
                        )

                    } else if (orgCursor!!.getString(orgCursor.getColumnIndex(ContactsContract.Data.MIMETYPE)).equals(
                            ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE
                        )
                    ) {

                        phoneJsonArray.add(phoneNum.replace(" ", "").replace("-", ""))
                    } else if (orgCursor!!.getString(orgCursor.getColumnIndex(ContactsContract.Data.MIMETYPE)).equals(
                            ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE
                        )

                        emailJsonArray.add(emailAddr.replace(" ", ""))
                    }
                }
            }
            orgCursor.close()
            personJsonObj.add("EMAIL_LIST", emailJsonArray)
            personJsonObj.add("PHONE_NUMBERS", phoneJsonArray)
            mainJsonArray.add(personJsonObj)
        }

    cursor.close()
    return mainJsonArray
}

为什么要将其转换为JSON？您可以从手机中读取联系人（姓名、号码等），并将其显示在listviewHello Yupi中，感谢您的快速回复。。。我需要将他们（联系人）发送到服务器
