出现导航栏时隐藏三点菜单项

Question

我想在导航栏出现时隐藏三点菜单项。
我发现了一些不错的主题如何隐藏三点菜单项：
How to disable/hide three-dot indicator(Option menu indicator) on ICS handsets
How do I hide a menu item in the actionbar?
但我找不到我的问题的解决方案。我希望能得到一些帮助。 :)

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.main_menu, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    infoDialogFragment.aboutMenuItem(this);
    return false;
}

@Override
protected void onPostCreate(@Nullable Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    actionBarDrawerToggle.syncState();
}


private void setNavigationDrawer() {
    navigationView.setNavigationItemSelectedListener(menuItem -> {


    });
    return false;
}

从您的活动中删除所有这些代码：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.main_menu, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    infoDialogFragment.aboutMenuItem(this);
    return false;
}
