AndroidHideNavigation DrawerAndroid Problem Overview
I have a navigation drawer. When an event is called, I want to hide one of my navigation menu item for user. How can I do that?
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sliding_menu);
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav drawer icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout1);
mDrawerList = (ListView) findViewById(R.id.list_slidermenu1);
navDrawerItems = new ArrayList<NavDrawerItem>();
// adding nav drawer items to array
// Home
navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));
// Profil
navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
// Prospek
navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
// Announcement
navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1), true,
cariTotal("http://192.168.0.23/api/android/announcement/").toString()));
// Logout
navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));
// Recycle the typed array
navMenuIcons.recycle();
//set event
mDrawerList.setOnItemClickListener(new SlideMenuClickListener());
// setting the nav drawer list adapter
adapter = new NavDrawerListAdapter(getApplicationContext(),
navDrawerItems);
mDrawerList.setAdapter(adapter);
// enabling action bar app icon and behaving it as toggle button
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.string.app_name,
R.string.app_name
){
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle(mTitle);
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getSupportActionBar().setTitle(mDrawerTitle);
//mDrawerList.bringToFront();
//mDrawerLayout.requestLayout();
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
// on first time display view for first nav item
displayView(0);
}
}
private void displayView(int position) {
// update the main content by replacing fragments
android.app.Fragment fragment = null;
switch (position) {
case 0:
fragment = new HomeFragment();
break;
case 1:
fragment = new ProfilFragment();
break;
case 2:
fragment = new ProspekFragment();
break;
case 3:
fragment = new AnnouncementFragment();
break;
case 4:
Logout();
break;
default:
break;
}
if (fragment != null) {
android.app.FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
setTitle(navMenuTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else {
// error in creating fragment
Log.e("SlidingMenu", "Error in creating fragment");
}

Android Solutions
Solution 1 - Android
NavigationView navigationView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
hideItem();
}
private void hideItem()
{
navigationView = (NavigationView) findViewById(R.id.nav_view);
Menu nav_Menu = navigationView.getMenu();
nav_Menu.findItem(R.id.nav_settings).setVisible(false);
}
Solution 2 - Android
This will work as setInvisibility(GONE):
Menu nav_Menu = navigationView.getMenu();
nav_Menu.findItem(R.id.nav_profile).setVisible(false);
nav_Menu.findItem(R.id.menu_login).setVisible(true);
nav_Menu.findItem(R.id.menu_logout).setVisible(false);
nav_Menu.findItem(R.id.menu_regsitration).setVisible(true);
Solution 3 - Android
Kotlin version
val navigationView: NavigationView = findViewById(R.id.nav_view) as NavigationView
val nav_Menu: Menu = navigationView.getMenu()
nav_Menu.findItem(R.id.nav_stock).setVisible(false)
Solution 4 - Android
You can delete the second item of listview via following code:
navDrawerItems.remove(2);
((BaseAdapter)adapter).notifyDataSetChanged();
Solution 5 - Android
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
Menu menu =navigationView.getMenu();
MenuItem target = menu.findItem(R.id.nav_target);
target.setVisible(false);
Solution 6 - Android
Hide/Show Navigation item
Make changes in your NavDrawerListAdapter as follow,
public class MyListAdapter extends BaseAdapter {
Context context;
ArrayList<ItemListModel> listMenuItem;
ArrayList<ItemListModel> listMenuItem1;
int hideViewIndex = -1;
public MyListAdapter(Context context, ArrayList<ItemListModel> listMenuItem) {
this.context = context;
this.listMenuItem = listMenuItem;
listMenuItem1=new ArrayList<ItemListModel>(listMenuItem);
}
@Override
public int getCount() {
return listMenuItem.size();
}
@Override
public Object getItem(int position) {
return listMenuItem.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
private class ViewHolder
{
private ImageView imgLogo;
private TextView txtItemName;
}
public void hideView(int pos)
{
listMenuItem.remove(pos);
notifyDataSetChanged();
}
public void showView(int pos)
{
listMenuItem.add(pos, listMenuItem1.get(pos));
notifyDataSetChanged();
}
@SuppressLint("InflateParams")
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
if(convertView == null)
{
LayoutInflater myLayoutInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = myLayoutInflater.inflate(R.layout.activity_item_list, null);
viewHolder = new ViewHolder();
viewHolder.imgLogo = (ImageView) convertView.findViewById(R.id.imgLogo);
viewHolder.txtItemName = (TextView) convertView.findViewById(R.id.txtItemName);
convertView.setTag(viewHolder);
}
else
{
viewHolder = (ViewHolder) convertView.getTag();
}
ItemListModel itemListModel = listMenuItem.get(position);
viewHolder.imgLogo.setImageDrawable(itemListModel.getImageLogo());
viewHolder.txtItemName.setText(itemListModel.getStrItemName());
return convertView;
}
and call this method in activity as follow,
adapter.hideView(2);
//adapter.showView(2);

//hide logout menu item when the user is not loggrd in
//Checking the condition whether the user is logged in or not
if (!SharedPrefManager.getmInstance(this).isLoggedIn()){
Menu nav_Menu = navigationView.getMenu();
nav_Menu.findItem(R.id.nav_logout).setVisible(false);
}
//SharedPrefManager .java class where we define the isLoggedIn Method()
import android.content.Context;
import android.content.SharedPreferences;

public class SharedPrefManager {
private static final String SHARED_PREF_NAME = "my_shared_pref";

}
public boolean isLoggedIn(){
SharedPreferences preferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
return preferences.getInt("user_id", -1) != -1;
}
