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

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,

//以上执行的语句是：SELECT * FROM sms WHERE (type=1) AND (1=1) group by (address)
order by date asc
