                    }

试试这个代码希望它能正常工作。

Dexter.withActivity(this)
            .withPermissions(Manifest.permission.READ_EXTERNAL_STORAGE,
                    Manifest.permission.WRITE_EXTERNAL_STORAGE)
            .withListener(new MultiplePermissionsListener() {
                @Override
                public void onPermissionsChecked(MultiplePermissionsReport report) {
                    if (report.areAllPermissionsGranted()) {
                        //do you stuf here
                    } else {
                        Toast.makeText(EditEventActivity.this, "Permission Denied! plz enable application permission from app settings!", Toast.LENGTH_LONG).show();
                    }
                }

                @Override
                public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
                    token.continuePermissionRequest();

                }

            }).check();
