我在Fragment中将ToolBar制作为ActionBar。我可以添加ActionBar菜单项,但是单击任何ActionBar菜单项时都无法收到点击响应。
我已经阅读了很多类似的问题,我尝试了所有问题,但仍然遇到问题,因此在这里提出了一个问题。
片段
public class DetailFragment extends Fragment {
@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
setHasOptionsMenu(true);
return inflater.inflate(R.layout.project_detail, container, false);
}
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
mToolBar = (Toolbar)view.findViewById(R.id.tb_toolbar);
((AppCompatActivity)getActivity()).setSupportActionBar(mToolBar);
mToolBar.setTitle(R.string.project_details);
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.project_detail_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.options:
// do something
break;
}
return true;
}
在我上面的代码中, onOptionsItemSelected 甚至没有被调用。 任何指针为什么?
我要对该片段进行夸大的活动-
public class TestJust extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test_just);
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.container, new ProjectDetailFragment());
ft.commit();
}
}
project_detail_menu.xml-
<?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/options"
android:title="options"
android:icon="@android:drawable/ic_menu_more"
app:showAsAction="always"/>
</menu>

尝试一下
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
menu.clear()
inflater.inflate(R.menu.project_detail_menu, menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.options:
// do something
return true;
default:
return super.onOptionsItemSelected(item);
}

解决方案:
您正在onCreateView()中呼叫Updating Homebrew...
==> Auto-updated Homebrew!
Updated 2 taps (homebrew/core, homebrew/cask).

请在onCreate()中调用该方法

在onCreate()中调用此方法可确保菜单必须参与Fragment。
然后
setHasOptionsMenu(true);
最后,
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
现在应该可以工作。

onCreateOptionMenu
中的初始化选项,然后检查它。您只需要充气菜单,不使用初始化选项,先初始化然后使用它即可。
like:MenuItem item = menu.findItem(R.id.option);
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
MenuItem item = menu.findItem(R.id.option);
}
