在 fragments android studio 中处理 appbar 中的点击事件
handle clickevent in appbar in fragments android studio
我的 fragment 中的自定义 appbar 遇到问题，当我单击应用栏中的任何项目时没有任何反应。我已经按照 this document 在我的片段中创建了一个应用栏，但仍然很成功。
我有一个 one activity，它只包含一个片段容器，我从中切换片段。在其中一个片段中，我想添加一个自定义片段拥有的应用栏。我首先创建了一个这样的菜单：
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/settings"
android:title="Settings"
android:icon="@drawable/ic_settings"
app:showAsAction="never">
</item>
<item
android:id="@+id/about"
android:title="About"
android:icon="@drawable/ic_about"
app:showAsAction="never">
</item>
<item
android:id="@+id/logout"
android:title="Logout"
android:icon="@drawable/ic_logout"
app:showAsAction="never">
</item>
</menu>
然后在我的 profile.xml 中添加了一个这样的工具栏：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
tools:context=".MainFragments.AddFragment">
<com.google.android.material.appbar.AppBarLayout
android:id="@+id/Bar_profile"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<com.google.android.material.appbar.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="@color/darkBlue"
app:layout_scrollFlags="scroll|snap|exitUntilCollapsed">
//alot of code in between....
<androidx.appcompat.widget.Toolbar
android:id="@+id/toolbar_prof"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/ThemeOverlay.AppCompat.Dark" />
</com.google.android.material.appbar.CollapsingToolbarLayout>
</com.google.android.material.appbar.AppBarLayout>
//more stuff implemented
</RelativeLayout>
但是，我的菜单没有膨胀，如果我通过 xml 膨胀它，当我点击任何项目时没有任何反应，这是怎么回事？谢谢！

我刚才注意到它可以工作，只是我的文字是白色的，因此没有显示出来。抱歉给您带来不便。
把这个放在你的片段中

public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
Toolbar toolbar = view.findViewById(R.id.my_toolbar);
toolbar.inflateMenu(R.menu.your_menu);
toolbar.setOnMenuItemClickListener(new OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
switch (item.getItemId()) {
case R.id.delete:
