在 Android 中没有得到 USSD 代码的响应

Question

我想拨打并获得拨打的 USSD 代码响应。 这是我的代码。 但是当我运行时，它在吐司上没有显示任何响应。

private void ussdResponse(String completeCode) {

    TelephonyManager manager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);

    if (checkSelfPermission(Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED || checkSelfPermission(Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {

        ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CALL_PHONE}, requestCode);
        ActivityCompat.requestPermissions(MainActivity.this , new String[]{Manifest.permission.READ_PHONE_STATE},requestCode);
        return;
    }

    manager.sendUssdRequest(completeCode, new TelephonyManager.UssdResponseCallback() {
        @Override
        public void onReceiveUssdResponse(TelephonyManager telephonyManager, String request, CharSequence response) {

            super.onReceiveUssdResponse(telephonyManager, request, response);

            Toast.makeText(MainActivity.this, "Success", Toast.LENGTH_SHORT).show();
            Toast.makeText(MainActivity.this, "USSD Result"+response.toString(), Toast.LENGTH_LONG).show();
        }

        @Override
        public void onReceiveUssdResponseFailed(TelephonyManager telephonyManager, String request, int failureCode) {

            super.onReceiveUssdResponseFailed(telephonyManager, request, failureCode);
            Toast.makeText(MainActivity.this, "Failed", Toast.LENGTH_SHORT).show();
            Toast.makeText(MainActivity.this, "USSD Response Failed.", Toast.LENGTH_SHORT).show();
        }

    }, new Handler());
}

compleCode代码包含 USSD 代码。 但是吐司什么也没显示。 任何人都可以找到我的解决方案。？ 或者有没有其他方法可以在我的应用程序中获得拨打的 USSD 响应？

我自己找到了答案。 我用这个 Api 来解决这个问题。 https://github.com/romellfudi/VoIpUSSD

这是我的代码：

HashMap map = new HashMap<>();
                        map.put("KEY_LOGIN",new HashSet<>(Arrays.asList("espere", "waiting", "loading", "esperando")));
                        map.put("KEY_ERROR",new HashSet<>(Arrays.asList("problema", "problem", "error", "null")));

                        final USSDApi ussdApi = USSDController.getInstance(MainActivity.this);
                        ussdApi.callUSSDInvoke("*786#", map, new USSDController.CallbackInvoke() {
                            @Override
                            public void responseInvoke(String message) {
                                // message has the response string data
                                String dataToSend = "data";// <- send "data" into USSD's input text
                                ussdApi.send(dataToSend,new USSDController.CallbackMessage(){
                                    @Override
                                    public void responseMessage(String message) {
                                        // message has the response string data from USSD
                                        Log.d("message", message);
                                    }
                                });
                            }

                            @Override
                            public void over(String message) {
                                // message has the response string data from USSD or error
                                // response no have input text, NOT SEND ANY DATA
                            }
                        });
