折叠 toolbar
时,我想要消失 appBarlayout
菜单,但我不知道怎么办。
我的代码在这里:
public class MainFragment extends BaseFragment implements Toolbar.OnMenuItemClickListener ...
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_main, container, false);
...
}
@Override
public int getMenu() {
return R.menu.search;
}
XML代码:

我想在折叠 appBarLayout ,gone
public int getMenu()
时,以及展开时显示此public int getMenu()
。
我怎么能?

使用AppBarLayout.OnOffsetChangedListener获取appbar状态{expand / collapse}, 然后在偏移值更改时隐藏appbar菜单。

使用app:layout_scrollFlags="scroll|enterAlways"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
