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;
}

I am trying to hide the menu in the TableLayout with ViewPager I want the menu only in the solutions tab. I used the onPrepareOptionsmenu to hide the menu in tabs except the solutions tab. the thing is my onOptionsItemSelected is not working.
code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inf = getMenuInflater();
inf.inflate(R.menu.simpleadd,menu);
// +getMenuInflater().inflate(R.menu.simpleadd, menu);
onPrepareOptionsMenu(menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
if (viewpager.getCurrentItem()==0){
menu.findItem(R.id.simpleadd).setVisible(false);
} else if(viewpager.getCurrentItem()==1){
menu.findItem(R.id.simpleadd).setVisible(false);
} else if(viewpager.getCurrentItem()==2){
menu.findItem(R.id.simpleadd).setVisible(true);
} else if(viewpager.getCurrentItem()==3){
menu.findItem(R.id.simpleadd).setVisible(false);
}else if(viewpager.getCurrentItem()==4){
menu.findItem(R.id.simpleadd).setVisible(false);
}
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.simpleadd:
startActivity(new Intent(this,NewSolution.class));
}
return super.onOptionsItemSelected(item);
}
thanks in advance,
You have used the layout's name in the switch case of onOptionsItemSelected.
Use menu item's id instead.
First, you need to get item id and then set compare with layout ids,
this helps you to set the functionality. Please find the below sample
code for your reference.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.simpleadd) {
// execute your code here
}
return super.onOptionsItemSelected(item);
}
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;
}
I have a TabGroup in my app. How can I have different actions items for each Tab ? I just found an example from here, but it is not enough for me.
Can someone provide some hints or at least a link ?
I'm using SlidingTabLayout, and this is the way i changed the Toolbar icons for each Tab.
I've 3 tabs, each tab got its own fragment, and in each fragment I've created the following:
Tab 1 fragment:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.tab_1_menu, menu);
}
Tab 2 fragment:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.tab_2_menu, menu);
}
And so on, hope this help .
Full Example with getItemId / Click
#Override
public boolean onCreateOptionsMenu(Menu menu) {
//Set The Menu View
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
//Menu Items, every fragment menu item
//Must have different ID
if (id == R.id.settings) {
//Do Something here
);
return true;
}
if (id == R.id.About) {
//Do Something here
);
return true;
}
if ( id == R.id.exit)
{
finish();
return true;
}
return super.onOptionsItemSelected(item);
}
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;
}
