推荐答案

您必须像这样首先设置previewbuilder:

You have to set previewbuilder first like this:

mPreviewBuilder.set(CaptureRequest.CONTROL_MODE, CameraMetadata.INFO_SUPPORTED_HARDWARE_LEVEL_FULL);

而不是

Range<Integer> range2 = characteristics.get(CameraCharacteristics.SENSOR_INFO_SENSITIVITY_RANGE);
                    int max1 = range2.getUpper();//10000
                    int min1 = range2.getLower();//100
                    int iso = ((progress * (max1 - min1)) / 100 + min1);
                    mPreviewBuilder.set(CaptureRequest.SENSOR_SENSITIVITY, iso);

progress是onProgressChanged(SeekBar seekBar, int progress, boolean user)覆盖方法中的seekBar的变量

progress is a variable for seekBar from onProgressChanged(SeekBar seekBar, int progress, boolean user) override method
