Answer 1

尝试这个 ：

JSONObject myJsonObject = new JSONObject("{\"Person Name\": \"abc\", \"Person Phone\": \"1234567890\"}");
String number = myJsonObject.optString("Person Phone").toString();
String name = myJsonObject.optString("Person Name").toString();
sendSms(number,someMessage);

在 sendSms 中这样做：

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNumber, null, message, null, null);

在您的 AndroidManifest.xml 文件中包含以下权限

<uses-permission android:name="android.permission.SEND_SMS" />

Answer 2

JSONObject jsonObj = new JSONObject((String) result);

String personName = jsonObj.getString("Person Name");
String phoneNumber = jsonObj.getString("Person Phone");
