从搜索栏获取输出的问题

Question

我正在尝试实现搜索栏，以允许用户选择相机的ISO。我已经在应用程序中找到了搜索栏，但是未显示ISO的读数（从搜索栏的进度中获取）

            CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraId);
            maxISO = rangeISO.getUpper();
            minISO = rangeISO.getLower();
            rangeISO = characteristics.get(CameraCharacteristics.SENSOR_INFO_SENSITIVITY_RANGE);
            Range<Long> exposureTimeRange = characteristics.get(CameraCharacteristics.SENSOR_INFO_EXPOSURE_TIME_RANGE);
        } catch (CameraAccessException e) {
            e.printStackTrace();
        }


        seekBar = findViewById(R.id.ISOSeekBar);
        seekBar.setOnSeekBarChangeListener(seekBarChangeListener);
        progress = seekBar.getProgress();
        ISOText = findViewById(R.id.ISOText);
        progress = progress /100;
        ISO = minISO + (minISO * progress);
        ISOText.setText("ISO: " + ISO);

    }

    SeekBar.OnSeekBarChangeListener seekBarChangeListener = new SeekBar.OnSeekBarChangeListener() {

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            progress = progress /100;
            ISO = minISO + (minISO * progress);
            ISOText.setText("ISO: " + ISO);
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }
    };```
