所以我正在学习node.js和facebook身份验证，我遇到了这个错误：
/home/lindan4/Git/HelloNodeJS/ChatTime/node_modules/passport-oauth2/lib/strategy.js:79
if (!verify) { throw new TypeError('OAuth2Strategy requires a verify callback'); }
^

const helper = require('../helpers');
module.exports = () => …每当我尝试设置 LinearLayout 的高度时，我总是会遇到以下异常：
java.lang.ClassCastException: android.widget.LinearLayout$LayoutParams cannot be cast to android.widget.RelativeLayout$LayoutParams
这是我的代码：
LinearLayout.LayoutParams hide = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 0);
LinearLayout.LayoutParams show = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 100);
driverMainOptions.setLayoutParams(hide);
mapDirections.setLayoutParams(show);
是否需要特定的导入语句才能正确执行？
