Android - remove three dots in SearchView

How can I remove the three dots to the right of my SearchView ?

set false in onPrepareOptionsMenu
#Override
public boolean onPrepareOptionsMenu (Menu menu) {
return false;
}

Maybe this helps you
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_activity, menu);
MenuItem searchMI = (MenuItem) menu.findItem(R.id.menu_search);
searchMI.setOnActionExpandListener(new OnActionExpandListener(){
#Override
public boolean onMenuItemActionCollapse(MenuItem menuItem) {
// Hide menu icon
return true;
}
#Override
public boolean onMenuItemActionExpand(MenuItem menuItem) {
// Show menu icon
return true;
}
});
return true;
}
You can show or hide icons like this:
menu.findItem(R.id.yourActionId).setVisible(true);
menu.findItem(R.id.yourActionId).setVisible(false);

You need to hide all others menu items one by one...
#Override
public boolean onMenuItemActionExpand (MenuItem item){
menu.getItem(MENU_MAIN_REFRESH).setVisible(false);
menu.getItem(MENU_MAIN_SETTINGS).setVisible(false);
menu.getItem(MENU_MAIN_EXIT).setVisible(false);
return true;
}

Hide optionmenu

I have a option Menu in my toolbar in app.but I want to Is unseen Some places.
What solution do you recommend to it my friends?
Toolbar toolbar=(Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
//codes...
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.optionmenu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.item1) {
return true;
}
return super.onOptionsItemSelected(item);
}
TO:

Just remove onCreateOptionsMenu and onOptionsItemSelected method from activity.

try : Open menu xml using ctrl + click on R.menu.optionmenu in your code. Delete all "item" in xml, if you want to add menu items afterwards.
or
try : remove onCreateOptionsMenu(Menu menu) and onPrepareOptionsMenu(Menu menu) from Activity if you don't want to use action bar menus at all.

You can change this code and try again :
#Override
public boolean onCreateOptionsMenu(Menu menu) {
if("Your condition")
{
getMenuInflater().inflate(R.menu.optionmenu, menu);
}
return true;
}

How to update menu item in android

I have an activity with menu items. Every time when user come to this activity, i want to update the value of textView with some Utility value. This is my code.
#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_my2, menu);
return true;
}
#Override
public boolean onPrepareOptionsMenu(Menu menu){
RelativeLayout badgeLayout = (RelativeLayout) menu.findItem(R.id.badge).getActionView();
TextView tv = (TextView) badgeLayout.findViewById(R.id.actionbar_notifcation_textview);
tv.setText(String.valueOf(Utility.ShoppingCartItemCount()));
return true;
}
This is updating the value only once (when launching activity). But when user moves from this activity and come on this activity again, this is not getting updated even value for Utility.ShoppingCartItemCount() is updated.
How to solve this?

Try invalidateOptionsMenu()
This will be call onCreateOptionsMenu(Menu) again.
edit)
I have some code like below
#Override
public boolean onCreateOptionsMenu(Menu menu) {
if (currentPage == 8) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_p, menu);
return true;
} else {
return false;
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.purchaseRestore:
// TODO: Restore purchase
return true;
case R.id.purchaseTerm:
// TODO: Show Term by WebView
return true;
default:
return super.onOptionsItemSelected(item);
}
}
When my user click other button, put invalidateOptionsMenu() after currentPage = 8 in Button's OnClickListener. In result, User can show Option Menu.
edit))
invalidateOptionsMenu() will force reload onCreateOptionsMenu and onPrepareOptionsMenu.
If this methods doesn't working for you, try to debug Utility.ShoppingCartItemCount().

Set visibility in Menu programmatically android

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;
}

How do I inflate an Android options menu and set an item to Enabled=false?

My XML menu definition sets the item R.id.menu_refresh's enabled state to false. When the app runs the menu item is greyed and disabled. Why is this code in the app not enabling the item?
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
MenuItem refresh = menu.getItem(R.id.menu_refresh);
refresh.setEnabled(true);
return true;
}
What am I missing?

Try menu.findItem() instead of getItem(). getItem() takes an index from [0, size) while findItem() takes an id.

this is what I do in my activity for the menu handling ...
//Android Activity Lifecycle Method
// This is only called once, the first time the options menu is displayed.
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mainmenu, menu);
return true;
}
//Android Activity Lifecycle Method
// Called when a panel's menu is opened by the user.
#Override
public boolean onMenuOpened(int featureId, Menu menu)
{
MenuItem mnuLogOut = menu.findItem(R.id.main_menu_log_out_id);
MenuItem mnuLogIn = menu.findItem(R.id.main_menu_log_in_id);
MenuItem mnuOptions = menu.findItem(R.id.main_menu_options_id);
MenuItem mnuProfile = menu.findItem(R.id.main_menu_profile_id);
//set the menu options depending on login status
if (mBoolLoggedIn == true)
{
//show the log out option
mnuLogOut.setVisible(true);
mnuLogIn.setVisible(false);
//show the options selection
mnuOptions.setVisible(true);
//show the edit profile selection
mnuProfile.setVisible(true);
}
else
{
//show the log in option
mnuLogOut.setVisible(false);
mnuLogIn.setVisible(true);
//hide the options selection
mnuOptions.setVisible(false);
//hide the edit profile selection
mnuProfile.setVisible(false);
}
return true;
}
//Android Activity Lifecycle Method
// called whenever an item in your options menu is selected
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
// Handle item selection
switch (item.getItemId())
{
case R.id.main_menu_log_in_id:
{
ShowLoginUI();
return true;
}
case R.id.main_menu_log_out_id:
{
ShowGoodbyeUI();
return true;
}
case R.id.main_menu_options_id:
{
ShowOptionsUI();
return true;
}
case R.id.main_menu_profile_id:
{
ShowProfileUI();
return true;
}
default:
return super.onOptionsItemSelected(item);
}
}
I like this approach because it makes the code nice and modular

Use menu.findItem() instead of getItem().
because findItem is used to find item by id.
