如何获得usdd测量字符串值？

如何解决如何获得usdd测量字符串值？

我找到了这个API here来完成我的工作，但我并没有知道如何将其应用到我的应用程序中

我知道有描述，但是我如何才能将api应用于onclick方法以运行ussd并获取测量值到字符串值，然后根据测量值忽略我喜欢的任何东西。谁能帮我逐步申请？ 我已经尝试过这样 在我声明的appcompatActivity中

 private HashMap map=new HashMap<>();
    private USSDApi ussdApi;

在oncreate方法中

USSDController.verifyAccesibilityAccess(this);
     USSDController.verifyOverLay(this);

    map.put("KEY_LOGIN",new HashSet<>(Arrays.asList("koyu","waiting","loading","tinish yitebku")));
    map.put("KEY_ERROR",new HashSet<>(Arrays.asList("chigir tefetrwal","problem","error","chigir")));
    ussdApi = USSDController.getInstance(this);

然后使用onclick方法

atidabira.setonClickListener(new View.OnClickListener() {
            @RequiresApi(api = Build.VERSION_CODES.M)
            @Override
            public void onClick(View v) {


            String suffix = Uri.encode("#");
            String ussd = "*" + "804"+suffix;



            Intent intent = new Intent(Intent.ACTION_CALL);
            intent.setData(Uri.parse("tel:" + ussd));
            if (checkSelfPermission(Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                String[] PERMISSIONS={Manifest.permission.CALL_PHONE};
                ActivityCompat.requestPermissions((Activity) mContext,PERMISSIONS,REQUEST);
            }
            else {
                startActivity(intent);
            }


            ussdApi.callUSSDInvoke(ussd,map,new USSDController.CallbackInvoke() {
                @Override
                public void responseInvoke(String message) {


                    Toast.makeText(mContext,""+message,Toast.LENGTH_SHORT).show();


                }

                @Override
                public void over(String message) {

                }
            });



        }
    });

解决方法

您需要做的就是创建一个ussd Response Callback，它将监听响应并在Telephony.sendUssdRequest上使用它，该方法需要三个参数（例如* 101＃，回调和Handler）的方法，如下所示：

    if (ActivityCompat.checkSelfPermission(activity,Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        return;
    }else{
        TelephonyManager telephonyManager=  (TelephonyManager)activity.getSystemService(Context.TELEPHONY_SERVICE);
        Handler handler = new Handler();

        TelephonyManager telephonyManagerBySlot=telephonyManager.createForSubscriptionId(slot);

        TelephonyManager.UssdResponseCallback callback = new TelephonyManager.UssdResponseCallback() {
            @Override
            public void onReceiveUssdResponse(TelephonyManager telephonyManager,String request,CharSequence response) {
                super.onReceiveUssdResponse(telephonyManager,request,response);
                Log.e("ussd",response.toString());
                Toast.makeText(activity,response.toString(),Toast.LENGTH_SHORT).show();

            }

            @Override
            public void onReceiveUssdResponseFailed(TelephonyManager telephonyManager,int failureCode) {
                super.onReceiveUssdResponseFailed(telephonyManager,failureCode);
                Toast.makeText(activity,"Rung USSD code",Toast.LENGTH_SHORT).show();

                Log.e("ussd","failed with code " + Integer.toString(failureCode));
            }
        };

        try {
            Log.e("ussd","trying to send ussd request");
            telephonyManagerBySlot.sendUssdRequest(ussdCode,callback,handler);
        }catch (Exception e){

            String msg= e.getMessage();
            Log.e("DEBUG",e.toString());
            e.printStackTrace();
        }
    }
