Can't find Menu ID

1)This is Code declare my id at menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="home"
android:icon="#drawable/home"
android:title="HOME"/>
<item
android:id="category"
android:icon="#drawable/category"
android:title="CATEGORY"/>
<item
android:id="basket"
android:icon="#drawable/basket"
android:title="BASKET"/>
<item
android:id="me"
android:icon="#drawable/me"
android:title="ME"/>
</menu>
This is code i call my id
private BottomNavigationView.OnNavigationItemSelectedListener navigation =
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.home:
Toast.makeText(HomeActivity.this, "HOME", Toast.LENGTH_SHORT).show();
break;
case R.id.category:
Toast.makeText(HomeActivity.this, "HOME", Toast.LENGTH_SHORT).show();
break;
}
return true;
}
};
I have error when i call category id
case R.id.category:
but at case R.id.home: ,the code is right means no wrong.
Question : Who know why i cannot call my id?
can anyone give suggest for me, i take long time to fix this code. mybe i miss something like dot or comma? hahahaha

<item android:id="home"
should be
<item android:id="#+id/home"
the same applies to the others

The issue is with all the ids in your menu XML file
change it to the following:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
item android:id="#+id/home"
android:icon="#drawable/home"
android:title="HOME"/>
<item
item android:id="#+id/category"
android:icon="#drawable/category"
android:title="CATEGORY"/>
<item
item android:id="#+id/basket"
android:icon="#drawable/basket"
android:title="BASKET"/>
<item
item android:id="#+id/me"
android:icon="#drawable/me"
android:title="ME"/>
</menu>

Android Activity Menu

I wanted to create an option menu which shows up similar to Whatsapp even if the device has its own "hardware" option button. The solution I found online worked just fine until I wanted to add another action to the Bar.
Menu:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:title=""
android:id="#+id/addViewedMovie"
android:icon="#mipmap/ic_add_to_queue_black_24px"
android:showAsAction="always"
></item>
<item
android:title=""
android:id="#+id/menu_overflow"
android:icon="#mipmap/ic_more_vert_white_48dp"
app:showAsAction="always">
<menu>
<item
android:id="#+id/show_settings"
app:showAsAction="never"
android:title="#string/setttings"/>
<item
android:id="#+id/show_help"
app:showAsAction="never"
android:title="#string/help"/>
<item
android:id="#+id/show_about"
app:showAsAction="never"
android:title="#string/about"/>
</menu>
</item>
</menu>
And this in my MainActivity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
With this the app forces the addViewedMovie Action into an Overflow-Menu. Does anyone know how to prevent this?

Try this code and tell me if its work.. you should use app:showAsAction not android:showAsAction also you do not need to use submenu to show 3 dots.. just below code works fine also show 3 dots
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:title="Movie"
android:id="#+id/addViewedMovie"
android:icon="#mipmap/ic_add_to_queue_black_24px"
app:showAsAction="always"/>
<item
android:id="#+id/show_settings"
app:showAsAction="never"
android:title="#string/setttings"/>
<item
android:id="#+id/show_help"
app:showAsAction="never"
android:title="#string/help"/>
<item
android:id="#+id/show_about"
app:showAsAction="never"
android:title="#string/about"/>
</menu>

Create a folder name Menu in your res folder.
menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:myapp="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/search"
android:icon="#drawable/ic_launcher"
myapp:showAsAction="ifRoom" />
<item android:id="#+id/abc"
android:title="ABC" />
<item android:id="#+id/abc1"
android:title="ABC1" />
<item android:id="#+id/abc2"
android:title="ABC2" />
</menu>
In java file put this:-
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.search:
return true;
case R.id.abc:
return true;
case R.id.abc1:
return true;
case R.id.abc2;
return true;
default:
return super.onOptionsItemSelected(item);
}
}

Simple.
use app instead of android as app is for design support library.
And so, in Gradle build in dependencies, you must have: compile com.android.support:design..... like that. But, I have seen that you already used it below. So,
Just use: app:showAsAction="never" instead of android:showAsAction="always" in your addViewedMovie item.
Remember: never means it will be on overflow menu item. always means is will show in action bar.

If you are using in a fragment, add below line in the onCreate
setHasOptionsMenu(true);
And two more functions
#Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
}
Inflate your views in the above method. Listen to the action in the below one.
#Override public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}

Popup menu on click of action bar Icon

I am trying to display a Popup menu on the click of an action bar Icon.
The problem is that I get a forced close of the app and the Popup menu does not display. What is wrong with my code? Thank you for your help.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_action, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
Toast.makeText(getApplicationContext(), "ItemSelected = " + item, Toast.LENGTH_SHORT).show();
case R.id.action_sort:
showPopup(item.getActionView());
}
return super.onOptionsItemSelected(item);
}
public void showPopup(View v) {
PopupMenu popup = new PopupMenu(this, v);
Toast.makeText(getApplicationContext(), "showPopup = " + popup, Toast.LENGTH_SHORT).show();
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.popup_menu, popup.getMenu());
popup.show();
}
menu_action.xml

don't pass MenuItem as View cause it s not.
so it s better to cast it as view like this
View menuItemView = findViewById(R.id.menu_overflow); // SAME ID AS MENU ID
PopupMenu popupMenu = new PopupMenu(this, menuItemView);
popupMenu.inflate(R.menu.counters_overflow);
// And define click listener here.
popupMenu.show();

Popup menu crash at show();

So I'm trying to create a popup menu which will popup when user presses on ImageButton.
I'm getting strange force close error on popupMenu.show():
case R.id.action_menu_edit_biljeske_uredi:
linearLayoutDodajBiljeskuBojeIOstalaSranja.setVisibility(View.VISIBLE);
imageButtonBiljeskeDodajBiljeskuBojaPozadine
= (ImageButton) findViewById(R.id.imageButtonBiljeskeDodajBiljeskuBojaPozadine);
imageButtonBiljeskeDodajBiljeskuBojaPozadine.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
PopupMenu popupMenu = new PopupMenu(getApplicationContext(),
imageButtonBiljeskeDodajBiljeskuBojaPozadine);
popupMenu.getMenuInflater().inflate(R.menu.menu_popup_biljeske_boje,
popupMenu.getMenu());
popupMenu.show();
}
});
}
Does anyone know why?

Replace getApplicationContext() with YourActivity.this. I think your problem will be solved.
Why getApplicationContext() is not working, visit https://possiblemobile.com/2013/06/context/ for detailed solution.
