I have a menu which is inflated from main_menu.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/act_sync"
android:showAsAction="always"
android:actionLayout="#layout/sync_action"
android:icon="#android:drawable/ic_popup_sync" />
</menu>
and here is the code in the activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
MyMessageHandler.debug("menu item selected");
switch(item.getItemId()){
case R.id.act_sync:
sync();
return true;
}
return super.onOptionsItemSelected(item);
}
But onOptionsItemSelected is not called when I touch the menu item. When I remove the actionLayout attribute of the menu item, it works fine. How can I fix this? Thanks.
you should use below snippet ( Just for reference )
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
final Menu m = menu;
final MenuItem item = menu.findItem(R.id.ActionConnection);
item.getActionView().setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
sync();
}
});
return true;
}
In addition to the answer provided by Vipul Shah.
Make sure you disable the clickable option of all items in your action layout:
android:clickable="false"
Otherwise, it may steal the click so that you still cant receive onClick call back.

I have a menu.xml and the code to show the menu in action bar. Do i have to add the code in every activity? Cause after this i use a switch case to get click, and more code, so i dont thing its the wright way to copy-paste the same code in every activity
#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_main, menu);
return true;
Is there a better way to do it as to work in all app (all activities)?
Create a BaseActivity class.
public class BaseActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_main, menu);
return true;
}
}
Now all activities that extend your base activity will have the same menu.
this is a guide for Android Menu
this is an example menu:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/new_game"
android:icon="#drawable/ic_new_game"
android:title="#string/new_game" />
<item android:id="#+id/help"
android:icon="#drawable/ic_help"
android:title="#string/help" />
</menu>
And then inflating it within your activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.game_menu, menu);
return true;
}
whe item clicked:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.new_game:
newGame();
return true;
case R.id.help:
showHelp();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
good luck and read the doc official for android
I want to add a searchview and checkbox into action bar menu. And this checkbox will be visible if searchview is opened. And in it's opposite case it will be hidden. How I can do this?
I do something below . But it doesnt work correctly. I want hide checkbox (In my notes) when searchview is closed.
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/search_button"
android:icon="#drawable/ic_icon_search"
android:title="Arama"
app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView">
</item>
<item
android:id="#+id/search_in_my_notes_checkbox"
app:showAsAction="ifRoom"
android:title="#string/search_in_my_notes"
android:checkable="true"
android:visible="false"
/>
</menu>
HomeActivity.java
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId() == R.id.search_button){
MenuItem searchInMyNotesCheckbox = (MenuItem)menu.findItem(R.id.search_in_my_notes_checkbox);
searchInMyNotesCheckbox.setVisible(true);
}
return super.onOptionsItemSelected(item);
}
I found an alternative solution. I will use two checkbox image with checked and unchecked. And I will override onCreateOptionsMenu like this :
#Override
public boolean onCreateOptionsMenu(final Menu menu) {
this.menu = menu;
getMenuInflater().inflate(R.menu.menu, menu);
MenuItem search = (MenuItem)menu.findItem(R.id.search_button2);
final MenuItem searchInMyNotesCheckbox = (MenuItem) menu.findItem(R.id.search_in_my_notes_checkbox);
MenuItemCompat.setOnActionExpandListener(search,
new MenuItemCompat.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem menuItem) {
// Return true to allow the action view to expand
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem menuItem) {
MenuItem searchInMyNotesCheckbox = (MenuItem) menu.findItem(R.id.search_in_my_notes_checkbox);
searchInMyNotesCheckbox.setVisible(false);
return true;
}
});
searchInMyNotesCheckbox.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
if(item.getIcon() == R.drawable.checked_checkbox){
item.setIcon(R.drawable.unchecked_checkbox);
}
else {
item.setIcon(R.drawable.checked_checkbox);
}
return false;
}
});
return super.onCreateOptionsMenu(menu);
}
So, that´s what I wanna know. How can I set the visibility of the menu programatically in Android?? This is how I have my menu:
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
public boolean onOptionsItemSelected (MenuItem item){
switch (item.getItemId()){
case R.id.menuregistrar:
break;
case R.id.menusalir:
break;
}
return true;
}
But this code is not on the onCreate, so I don´t know how to set one item visible or invisible programmatically (in my case, I want the "menuregistrar" to be invisible once I have registered my application and forever.
Put this method in your Activity
public boolean onPrepareOptionsMenu(Menu menu)
{
MenuItem register = menu.findItem(R.id.menuregistrar);
if(userRegistered)
{
register.setVisible(false);
}
else
{
register.setVisible(true);
}
return true;
}
in shorter version you could write:
MenuItem register = menu.findItem(R.id.menuregistrar);
register.setVisible(!userRegistered); //userRegistered is boolean, pointing if the user has registered or not.
return true;
I would simplify Adil's solution even further with the following:
public boolean onPrepareOptionsMenu(Menu menu)
{
MenuItem registrar = menu.findItem(R.id.menuregistrar);
registrar.setVisible(!isRegistered);
return true;
}
Simply do one thing get the id of the item of menu from this line:
Menu menu =navigationView.getMenu();
MenuItem nav_dashboard = menu.findItem(R.id.nav_dashboard);
and than make it visible it accourding to you by this line:
nav_dashboard.setVisible(true/false);
Menu Object has a property to set the visibility of a menu's item using setVisible(boolean)//
Example
private Menu menu_change_language;
...
...
#Override
public boolean onCreateOptionsMenu(Menu menu) {
...
...
menu_change_language = menu;
...
...
return super.onCreateOptionsMenu(menu);
}
use code below for hiding Menu Item:
if(menu_change_language != null){
menu_change_language.findItem(R.id.menu_change_language)
.setVisible(false);
}
Use public boolean onPrepareOptionsMenu (Menu menu) it is called everytime you press the menu button and do your stuff there. or use your oncreateoptionsmenu() in different activities to inflate different menus - this one is called only once.
Cheers
If you want to change the visibility inside the onOptionsItemSelected whenever you click the menu
#Override
public boolean onOptionsItemSelected(MenuItem item) {
item.setVisible(true);
return true;
}
OR
for item in the menu that you didn't click on
private Menu globalMenuItem;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu."menu Xml Name", menu);
globalMenuItem = menu;
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
globalMenuItem.findItem(R.id."id of the menu item").setVisible(true);
return true;
}
In onCreateOptionsMenu I'm setting an action view with:
MenuItem item = ..
item.setActionView(action_view)
item.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
and it works ok. But I want to move this to my xml menu and I can't seem to make it show. It only shows up the title. I tried many versions, like:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourApp="http://schemas.android.com/apk/lib/myPackage.myClass" >
<item
android:id="#+id/item"
yourApp:actionViewClass="action_view"
android:showAsAction="always" or youtApp:showAsAction="always"
android:title="title"
</item>
The problem must be it getting to the action_view variable, but I can't seem to figure it out
Did you inflate the menubar?
#Override
public void onCreateOptionsMenu (Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_name, menu);
mMenu = menu;
if(mMenu != null){
MenuItem item = mMenu.findItem(R.id.item_id);
if(item != null){
item.setVisible(false);
}
}
super.onCreateOptionsMenu(menu, inflater);
}
Also do you have setHasOptionsMenu(true); #onCreate() function?
Try this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.item:
// Write your action_view here
break;
case R.id.your_other_item_id:
//Your other Menu item logic
break;
}
return super.onOptionsItemSelected(item);
}
