接下来重要的打电话

9 打电话、发短信和邮件,取得手机 IMEI 号
 
以下实现对电话功能的基本操作。
1、引用以下单元
uses
  Androidapi.JNI.Net, FMX.Platform, FMX.Helpers.Android,
   Androidapi.JNI.GraphicsContentViewText,
   Androidapi.JNI.JavaTypes, FMX.MediaLibrary.Actions, FMX.StdActns,
   Androidapi.JNIBridge, Androidapi.Helpers,
   Androidapi.JNI.Telephony, FMX.PhoneDialer , Androidapi.JNI.Os
2、建立如下函数
   public
     { Public declarations }
     TelephonyManager: JTelephonyManager;
     procedure Call_URI(const AAction: JString; const AURI: string);
     //  打电话、打开地图显示某个坐标点  、发送电子邮件、播放音乐
     procedure PhoneCall(phoneNumber: string); // 打电话
     procedure GetSN; //  获取Android手机 SIM卡串号
     procedure SentSMS(phoneNumber , SMSstring: string); // 直接没有任何提示的发送短信
procedure SentSMSfromIntent(phoneNumber , SMSstring: string); // 调用系统程序发短信
function FetchSms: string; // 收短信
 
3、实现函数功能
procedure TForm1.PhoneCall(phoneNumber: string); // 打电话
var
   phone: IFMXPhoneDialerService;
begin
   if TPlatformServices.Current.SupportsPlatformService(IFMXPhoneDialerService,
     IInterface(phone)) then
   begin
     phone.Call(phoneNumber);
     //  监听电话状态请用phone.OnCallStateChanged事件
   end;
end;
 
procedure TForm1.SentSMSfromIntent(phoneNumber , SMSstring: string);
//  调用系统程序发短信
var

   uri: Jnet_Uri;
   Intent: JIntent;
begin
   uri := StrToJURI(‘smsto:‘ + phoneNumber);
   Intent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_SENDTO, uri);

   Intent.putExtra(StringToJString(‘sms_body‘), StringToJString(SMSstring));
   SharedActivityContext.startActivity(Intent);
end;
 
procedure TForm1.SentSMS(phoneNumber , SMSstring: string);
//  直接没有任何提示的发送短信
var
   j: JSmsManager;
begin
   j := tjsmsmanager .Create;
   j.sendMultipartTextMessage(StringToJString(phoneNumber), nil,
     j.divideMessage(StringToJString(SMSstring)), nil, nil);
end;
 
procedure TForm1.GetSN; //  获取Android手机SIM卡串号
var
   TelephonyServiceNative: JObject;
begin
   TelephonyServiceNative := SharedActivityContext.getSystemService
     (TJContext.JavaClass.TELEPHONY_SERVICE);
   if Assigned(TelephonyServiceNative) then
     TelephonyManager := TJTelephonyManager .Wrap
        ((TelephonyServiceNative as ILocalObject).GetObjectID);
 
   // TelephonyManager .getDeviceId 取IMEI
   //  TelephonyManager .getLine1Number  取 MSISDN   手机号,大部分 SIM 卡中不会写入这个
信息
   // TelephonyManager .getSimSerialNumber 取 ICCID
   //  TelephonyManager .getSubscriberId 取 IMSI   运营商实际上是用这个查询的他那张对应
电话号码的表
end;
 
function TForm1.FetchSms: string; // 收短信
var

   cursor: JCursor;
   uri: Jnet_Uri;
   address, person, msgdatesent, protocol, msgread, msgstatus, msgtype,
     msgreplypathpresent, Subject, body, servicecenter , locked: string;
   msgunixtimestampms: int64;
   addressidx, personidx, msgdateidx, msgdatesentidx, protocolidx, msgreadidx,
     msgstatusidx, msgtypeidx, msgreplypathpresentidx, subjectidx, bodyidx,
     servicecenteridx, lockedidx: integer;
begin
   uri := StrToJURI(‘content://sms/inbox‘); //收件箱

  // cursor := SharedActivity.getContentResolver .query(uri, nil, nil, nil, nil);
     cursor := SharedActivity.
     managedQuery(
                        StrToJURI(‘content://sms/inbox‘), //StrToJURI(‘content://sms/‘)所有短信, 含
发件箱
                        nil,
                        StringToJString(‘1=1)  group  by  (address‘),//类似于 SQL语句,注意,括号只
有一半,原因中它已经有一对括号了
                        nil,
                        StringToJString(‘date asc‘)); //desc  降序
   //以上执行的语句是:SELECT  *  FROM  sms WHERE  (type=1)  AND  (1=1)  group  by  (address)
order by date asc
   addressidx := cursor .getColumnIndex(StringToJstring(‘address‘));//电话
   personidx := cursor .getColumnIndex(StringToJstring(‘person‘));
   msgdateidx := cursor .getColumnIndex(StringToJstring(‘date‘));
   msgdatesentidx := cursor .getColumnIndex(StringToJstring(‘date_sent‘));

   msgreadidx := cursor .getColumnIndex(StringToJstring(‘read‘));
   msgstatusidx := cursor .getColumnIndex(StringToJstring(‘status‘));
   msgtypeidx := cursor .getColumnIndex(StringToJstring(‘type‘));

     (StringToJstring(‘reply_path_present‘));
   subjectidx := cursor .getColumnIndex(StringToJstring(‘subject‘));
   bodyidx := cursor .getColumnIndex(StringToJstring(‘body‘));
   servicecenteridx := cursor .getColumnIndex(StringToJstring(‘service_center‘));
   lockedidx := cursor .getColumnIndex(StringToJstring(‘locked‘));
//   while (cursor .moveToNext) do//对所有短信的循环
//   begin
     cursor .moveToLast;//最后一条
     address := JStringToString(cursor .getString(addressidx));
     person := JStringToString(cursor .getString(personidx));
     msgunixtimestampms := cursor .getLong(msgdateidx);

     msgdatesent := JStringToString(cursor .getString(msgdatesentidx));
     protocol := JStringToString(cursor .getString(protocolidx));
     msgread := JStringToString(cursor .getString(msgreadidx));
     msgstatus := JStringToString(cursor .getString(msgstatusidx));
     msgtype := JStringToString(cursor .getString(msgtypeidx));
     msgreplypathpresent := JStringToString
        (cursor .getString(msgreplypathpresentidx));
     Subject := JStringToString(cursor .getString(subjectidx));
     body := JStringToString(cursor .getString(bodyidx));
     servicecenter := JStringToString(cursor .getString(servicecenteridx));
     locked := JStringToString(cursor .getString(lockedidx));
     Result := IntToStr(trunc(msgunixtimestampms / 1000))+#13

     + ‘号码:‘ + address +#13
     + ‘person:‘ + person +#13
     + ‘msgdatesent:‘ + msgdatesent +#13
     + ‘protocol:‘ + protocol +#13

//   end;
end;
