Usage

From source file:com.example.android.camera2basic.Camera2BasicFragment.java

@Override
public void onStopTrackingTouch(SeekBar seekBar) {
    switch (seekBar.getId()) {
    case R.id.iso: {
        Range<Integer> range = mCameraCharacteristics.get(CameraCharacteristics.SENSOR_INFO_SENSITIVITY_RANGE);
        int max = range.getUpper();
        int min = range.getLower();
        isoValue = ((seekBar.getProgress() * (max - min)) / 100 + min);
        createCameraPreviewSession_ISO();
        break;/*from   w  w w.  ja va 2 s .  c  o  m*/
    }
    case R.id.focus: {
        float distance = mCameraCharacteristics.get(CameraCharacteristics.LENS_INFO_MINIMUM_FOCUS_DISTANCE);
        focusValue = seekBar.getProgress() * distance / 100;
        createCameraPreviewSession_FOCUS();
        break;
    }
    default:
