BaseActivity

@Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
            @NonNull int[] grantResults) {
      PermissionAdapter.getInstance(this).onRequestPermissionsResult(requestCode,permissions,grantResults);
    }

使用

PermissionAdapter.getInstance(UserSettingsActivity.this).requestCameraPermission(new PermissionAdapter.PermissionVerifyCallBack() {
                    @Override
                    public void onPermissionGet() {
                        //......
                    }

                    @Override
                    public void onPermissionLost() {
                        ToastUtils.makeToast(getString(R.string.permission_lost));
                    }
                });
