一 :声明常量
private static final int PERMISSIONS_REQUEST_CAMERA = 800;

二:注册权限
cameraView.getCameraControl().setPermissionCallback(permissionCallback);

三:请求权限
private PermissionCallback permissionCallback = new PermissionCallback() {
    @Override
    public boolean onRequestPermission() {
        ActivityCompat.requestPermissions(BaiduOCRActivity.this,new String[] {Manifest.permission.CAMERA},PERMISSIONS_REQUEST_CAMERA);
        return false;
    }
};

四:权限执行

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,@NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) {
        case PERMISSIONS_REQUEST_CAMERA: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                cameraView.getCameraControl().refreshPermission();
            } else {
                Toast.makeText(getApplicationContext(), com.baidu.ocr.ui.R.string.camera_permission_required, Toast.LENGTH_LONG).show();
            }
            break;
        }
        default: break;
    }
}
