seekbar之间的链接：贷款模拟器

Question

我正在尝试使用搜索栏创建贷款模拟器应用程序，当您更改搜索栏时，例如每月的还款额，贷款金额和也会改变的每月还款次数，我尝试了在贷款金额和每月付款，但没有给我我想要的结果

   public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.fragment_simulation,container, false);

        final double t = 0.045;
         final SeekBar seek_bar  =(SeekBar) view.findViewById(R.id.seekBar);
        final TextView text_view =(TextView) view.findViewById(R.id.textView);
        final SeekBar seek_bar2  =(SeekBar) view.findViewById(R.id.seekBar2 );
        final TextView text_view12 =(TextView) view.findViewById(R.id.textView12);
        final SeekBar seek_bar3  =(SeekBar) view.findViewById(R.id.seekBar3);
        final TextView text_view8 =(TextView) view.findViewById(R.id.textView8);


        //amount of the loan
        //seek_bar1
        seek_bar.setMax(200000);
        seek_bar.setMin(500);
        text_view.setText("Covered: " + seek_bar.getProgress()+ "/"+seek_bar.getMax());
        seek_bar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                progress_value = progress;
                text_view.setText("Covered: " + progress+ "/"+seek_bar.getMax());
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {
                text_view.setText("Covered: " + progress_value + "/"+seek_bar.getMax());

            }
        });
        //number of monthly payments
        //seek_bar2
        seek_bar2.setMin(6);
        seek_bar2.setMax(84);

        text_view12.setText("Covered: " + seek_bar2.getProgress()+ "/"+seek_bar2.getMax());

        seek_bar2.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override

                progress_value1 = progress;
                text_view12.setText("Covered: " + progress+ "/"+seek_bar2.getMax());

                int b = (int)((progress_value*0.045/12)/1-pow(1+0.045/12,-progress_value2));
                seek_bar3.setProgress(b);

            }

            @Override

            }

            }
        });

        //payment per month
        //seek_bar3
        seek_bar3.setMax(34007);
        seek_bar3.setMin(200);
        text_view8.setText("Covered: " + seek_bar3.getProgress()+ "/"+seek_bar3.getMax());


        seek_bar3.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

                int a = (int)(((progress_value2*(1-pow(1+0.045/12,-progress_value1)))*12)/0.045);
                seek_bar.setProgress(a);

                double b = Math.log((-progress_value2)/(0.045/12)*progress_value - progress_value2)/Math.log(1+0.045/12);
                int c = (int)b;
                seek_bar2.setProgress(c);


            }
