如何在 Luaj 中获取"android.provider.ContactsContract.Contacts"字段

这是我的一个回答。当然，你需要在清单文件中获取权限。

    cr = activity:getContentResolver()
    contacts = luajava.bindClass("android.provider.ContactsContract")
    build = luajava.bindClass("android.os.Build")

    D_Name = build.VERSION.SDK_INT >= build.VERSION_CODES.HONEYCOMB and contacts.Contacts.DISPLAY_NAME_PRIMARY or contacts.Contacts.DISPLAY_NAME

    cur = cr:query(contacts.Contacts.CONTENT_URI)
    local count = cur and cur:getCount() or -1
    print(count)
    if cur and count > 0 then
        while cur:moveToNext() do
            id = cur:getString(cur:getColumnIndex(contacts.Contacts._ID))
            name = cur:getString(cur:getColumnIndex(D_Name))

            if cur:getInt(cur:getColumnIndex(contacts.Contacts.HAS_PHONE_NUMBER)) > 0 then
                pCur = cr:query(contacts.CommonDataKinds.Phone.CONTENT_URI, nil, contacts.CommonDataKinds.Phone.CONTACT_ID .. " = ?", ({id}), nil)
                print(pCur:getCount())
                while pCur:moveToNext() do
                    phoneNo = pCur:getString(pCur:getColumnIndex(contacts.CommonDataKinds.Phone.NUMBER))
                    print("Name: " .. name, "Phone Number: " .. phoneNo)
                end
                pCur:close()
            end

            pCur = cr:query(contacts.CommonDataKinds.Email.CONTENT_URI, nil, contacts.CommonDataKinds.Email.CONTACT_ID .. " = ?", ({id}), nil)
            print(pCur:getCount())
            if pCur then
                while pCur:moveToNext() do
                    Email_data = pCur:getString(pCur:getColumnIndex(contacts.CommonDataKinds.Email.DATA))
                    print("Name: " .. name, "Email_data: " .. Email_data)
                end
            end
            pCur:close()

            pCur = cr:query(contacts.Data.CONTENT_URI, nil, contacts.Data.CONTACT_ID .. " = " .. id)
            print(pCur:getCount())
            if pCur then
                while pCur:moveToNext() do
                    skype_type = pCur:getInt(pCur:getColumnIndex(contacts.CommonDataKinds.Im.PROTOCOL))
                    print(skype_type, contacts.CommonDataKinds.Im.PROTOCOL_SKYPE)
                    if contacts.CommonDataKinds.Im.PROTOCOL_SKYPE == skype_type then
                        imName = pCur:getString(pCur:getColumnIndex(contacts.CommonDataKinds.Im.DATA))
                        print("Name: " .. name, "skype_type: " .. skype_type .. "imName: " .. imName)
                    end
                end
            end
            pCur:close()
        end
    end
    if cur then
        cur:close()
    end
