片段加载后 DrawerLayout 不可点击

仅供参考，我没有使用 Android.R.Id，而是使用我自己的 R.id.fragmentContainer 来加载片段。但显然，抽屉布局在 FrameLayout 中加载的片段下。如果我单击 DrawerLayout 上的项目，片段会收到手势，而不是 DrawerLayout，尽管它仍然可以正确显示。
伙计们，我需要你们的两分钱。感谢所有的回答和评论。

将同一个侦听器设置为多个视图。
sideBarHome.setOnClickListener(clickListener);
sideBarSettings.setOnClickListener(clickListener);
将此clicklistener对象引用到视图，您可以使用相同的逻辑来区分视图
View.OnClickListener clickListener = new View.OnClickListener() {
@Override

if (view.getId() == R.id.side_item_home) {
