Question

我希望能够将紧急短信发送到列表中的任意数量的电话号码。我已经完成了大部分工作，但我无法弄清楚如何将字符串（电话）发送到列表中的所有数字。目前它只发送到最后一个号码。我有一个片段，你把数字放入列表，我使用共享偏好来发送详细信息，然后从另一个片段发送，你按下按钮，它意味着发送短信。但我不知道列表中可能有多少个数字。

我也希望它每10分钟发一次，但事后我会继续处理。

提前致谢。

 case R.id.settings_my_health_alert_help_button:
            String phone = sharedpreferences.getString("phone", "");
            if (phone.isEmpty()) {
                Toast.makeText(getActivity(), "No emergency contact added", Toast.LENGTH_LONG).show();
            } else {
                SmsManager sms = SmsManager.getDefault();
                //send sms
                sms.sendTextMessage(phone, null, "Emergency At: " + address, null, null);
            }

编辑：我想我会给你更多信息，因为我可能首先应该这样做：这是将联系人放入列表视图的地方。

在电话列表中添加您的电话号码并转到下一个活动

ArrayList<String> list= new ArrayList<String>();
intent.putExtra("phone", list);

获取数据

 ArrayList<String> myList = (ArrayList<String>) getIntent().getSerializableExtra("phone");

或

发送电话号码作为字符串空格分隔或逗号分隔

String phone="*************,*************,**********";

使用java split方法

SmsManager sms = SmsManager.getDefault(); String[] numbers=phone.split(","); for(String s:numbers){ //send sms }

从片段
获取数据
ArrayList<String> myList =(ArrayList<String>)getActivity().getIntent().getSerializableExtra("phone");
