I am trying to replace the menu item to another menu item after selection. I tried the following but it is not working as expected. Any solutions to this. thanks.
The menu.xml file is:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/add" android:visible="true" android:enabled="true" android:title="Add"></item>
<item android:id="#+id/delete" android:visible="false" android:enabled="true" android:title="Delete"></item>
</menu>
The code inside MyActivity.java is:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.defaultmenu, menu);
return true;
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
if(isAdded) {
menu.removeItem(R.id.add);
menu.add(0, R.id.delete, 0, "Delete");
} else {
menu.removeItem(R.id.delete);
menu.add(0, R.id.add, 0, "Add");
}
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.add:
isLogin = true;
return true;
case R.id.delete:
isLogin = false;
return true;
default:
return super.onOptionsItemSelected(item);
}
}
To refresh your menu call invalidateOptionsMenu();
And i guess in onPrepareOptionsMenu, you can do..
if(isAdded) {
menu.findItem(R.id.add).setVisible(false);
menu.findItem(R.id.delete).setVisible(true);
return true;
} else {
menu.findItem(R.id.add).setVisible(true);
menu.findItem(R.id.delete).setVisible(false);
return true;
}
return super.onPrepareOptionsMenu(menu);
Try like this
public static final int ADD_CATEGORY_INDEX = Menu.FIRST;
public static final int DELETE_CATEGORY_INDEX= Menu.FIRST+1;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, ADD_CATEGORY_INDEX, 0, "Add");
menu.add(0, DELETE_CATEGORY_INDEX, 0, "delete");
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case ADD_CATEGORY_INDEX:
break;
}
case DELETE_CATEGORY_INDEX:
break;
}
return true;
}
I Changed the onPrepareOptionsMenu, now it's working fine.
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
//menu.clear();
if(isadded) {
menu.removeItem(R.id.add);
menu.removeItem(R.id.delete);
menu.add(0, R.id.delete, 0, "Delete");
} else {
menu.removeItem(R.id.add);
menu.removeItem(R.id.delete);
menu.add(0, R.id.add, 0, "Add");
}
return super.onPrepareOptionsMenu(menu);
}

hi frnds am creating an application which is a tab application.
in my Home which extends sherlockFragmentActivity, i am inflating menu.xml and includes code for on optionMenuitem click listener. The Fragmentactivity contains tabhost and on each tab it load fragments.
this is my menu.xml
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:showAsAction="always"
android:icon="#drawable/setting_selector"
android:title=""
>
<menu >
<item
android:id="#+id/Profile"

android:title="Change password"/>
<item
android:id="#+id/logout"
android:showAsAction="ifRoom"
android:title="Logout"/>
</menu>
</item>
and this is my onCreateOptionMenu and onOptionItemSelected methods in class Home
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
getSupportMenuInflater().inflate(R.menu.main, menu);
SubMenu subMenu = (SubMenu) menu.getItem(0).getSubMenu();
if(userType.equals("admin"))
subMenu.getItem(1).setVisible(true);
else
subMenu.getItem(1).setVisible(false);
return true;
}
and this is my onOptionItemSelected method
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId()) {
case R.id.Profile:
break;
case R.id.changePword :
break;
case R.id.chngDoctor :
break;
case R.id.logout:
Home.this.finish();
break;
}
return true;
}
i need to add some menus depending on tab change. that is on tab change i load different fragments and when fragment changes i need to add new items to the menu. my ListFrag which extends SherlockFragment and it will load when i click on the 3 rd tab. when this fragment load i need to add 1 menu item to the menu
Try the following way.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, 0, 0, "Option1").setShortcut('3', 'c');
menu.add(0, 1, 0, "Option2").setShortcut('3', 'c');
menu.add(0, 2, 0, "Option3").setShortcut('4', 's');
SubMenu sMenu = menu.addSubMenu(0, 3, 0, "SubMenu"); //If you want to add submenu
sMenu.add(0, 4, 0, "SubOption1").setShortcut('5', 'z');
sMenu.add(0, 5, 0, "SubOption2").setShortcut('5', 'z');
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 0:
// code for option1
return true;
case 1:
// code for option2
return true;
case 2:
// code for option3
return true;
case 4:
// code for subOption1
return true;
case 5:
// code for subOption2
return true;
}
return super.onOptionsItemSelected(item);
}
This may help you.
In the menu.xml you should add all the menu items. Then you can hide items that you don't want to see in the initial loading.
<item
android:id="#+id/action_newItem"
android:icon="#drawable/action_newItem"
android:showAsAction="never"
android:visible="false"
android:title="#string/action_newItem"/>
Add setHasOptionsMenu(true) in the onCreate() method to invoke the menu items in your Fragment class.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
You don't need to override onCreateOptionsMenu in your Fragment class again. Menu items can be changed (Add/remoev) by overriding onPrepareOptionsMenumethod available in Fragment.
#Override
public void onPrepareOptionsMenu(Menu menu) {
menu.findItem(R.id.action_newItem).setVisible(true);
super.onPrepareOptionsMenu(menu);
}
here is an example...it might help you...
private static final int MENU_ADD = Menu.FIRST;
private static final int MENU_LIST = MENU.FIRST + 1;
private static final int MENU_REFRESH = MENU.FIRST + 2;
private static final int MENU_LOGIN = MENU.FIRST + 3;
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
menu.clear();
if(enableAdd)
menu.add(0, MENU_ADD, Menu.NONE, R.string.your-add-text).setIcon(R.drawable.your-add-icon);
if(enableList)
menu.add(0, MENU_LIST, Menu.NONE, R.string.your-list-text).setIcon(R.drawable.your-list-icon);
if(enableRefresh)
menu.add(0, MENU_REFRESH, Menu.NONE, R.string.your-refresh-text).setIcon(R.drawable.your-refresh-icon);
if(enableLogin)
menu.add(0, MENU_LOGIN, Menu.NONE, R.string.your-login-text).setIcon(R.drawable.your-login-icon);
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
switch (item.getItemId()) {
case MENU_ADD: doAddStuff(); break;
case MENU_LIST: doListStuff(); break;
case MENU_REFRESH: doRefreshStuff(); break;
case MENU_LOGIN: doLoginStuff(); break;
}
return false;
based on Gunaseelan answer
#Override
public boolean onPrepareOptionsMenu(Menu menu)
{
menu.removeGroup(1);
if (iotsnames.isEmpty()) return true;
for (int i=0; i<iotsnames.size(); i++ ){
menu.add(1, i, 0, iotsnames.get(i) );
}
return true;
}
use onPrepareOptionsMenu method and clear all menu first using
menu.clear();
then add menu.
Also refer here.. check its onPrepareOptionsMenu method
I am using Android ICS 4.0.3 and I downloaded Ancal project and studying it. I added some option menu in a activity but it can't call opOptionsItemSelected method. Here is my code:
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu(menu);
String displayText = dateFormatFull.format(new Date());
switch(iCurrentAgendaViewType) {
case AgendaView.viewMode.DAY:
displayText = dateFormatFull.format(CurrentAgendaView.GetViewStartDate().getTime()).toString();
break;
case AgendaView.viewMode.WEEK:
displayText = dateFormatFull.format(CurrentAgendaView.GetViewStartDate().getTime()).toString();
break;
case AgendaView.viewMode.MONTH:
displayText = dateFormatMonth.format(CurrentAgendaView.GetCurrentSelectedMonthAsCalendar().getTime()).toString();
break;
}
if (iCurrentAgendaViewType == AgendaView.viewMode.TODAY) {
menu.add(Menu.NONE, android.R.id.button2, 1, displayText).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
} else {
menu.add(Menu.NONE, R.drawable.ic_arrow_left, 0, "").setIcon(R.drawable.ic_arrow_left).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
menu.add(Menu.NONE, android.R.id.button2, 1, displayText).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
menu.add(Menu.NONE, R.drawable.ic_arrow_right, 2, "").setIcon(R.drawable.ic_arrow_right).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
}
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
if (DEBUG) {
Log.d(TAG, "============ onOptionsItemSelected ===========");
}
switch (item.getItemId())
{
case R.drawable.ic_arrow_left:
CurrentAgendaView.SetPrevViewItem();
RefreshAgendaAfterViewItemChange();
return true;
case R.drawable.ic_arrow_right:
CurrentAgendaView.SetNextViewItem();
RefreshAgendaAfterViewItemChange();
return true;
case miNewAppt:
openActAppointment(-1, -1, -1);
return true;
case miNewTask:
openActTask(-1);
return true;
case miNewNote:
openActNote(-1);
return true;
case miShowAllTasks:
{
item.setChecked(!item.isChecked());
prefs.bShowAllTasks = item.isChecked();
prefs.Save();
refreshData();
menuItemUpdateIcons(item);
return true;
}
case miOptions:
openActOptions();
return true;
case mTimeZone:
showTimeZone();
return true;
case miAbout:
openActViewAbout();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
I added actionbar menus at run time like the image but when I debug the above code, nothing call onOptionsItemSelected method.
What is wrong about this?
Thanks in advance.
I found the cause. The above activity extends CommonActivity. CommonActivity already overided onMenuItemSelected method. So I override onMenuItemSelected method like below:
public abstract class CommonActivity extends Activity {
#Override
public boolean onMenuItemSelected(int featureId, MenuItem item)
{
if (item.getItemId() == android.R.id.home){
finish();
}
return true;
}
}
public class AnCal extends CommonActivity implements OnNavigationListener{
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
String displayText = getCurrentViewDateText();
if (iCurrentAgendaViewType == AgendaView.viewMode.TODAY) {
menu.add(Menu.NONE, android.R.id.button2, 1, displayText).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
} else {
menu.add(Menu.NONE, android.R.id.button1, 0, "Prev").setIcon(R.drawable.ic_arrow_left).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
menu.add(Menu.NONE, android.R.id.button2, 1, displayText).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
menu.add(Menu.NONE, android.R.id.button3, 2, "Next").setIcon(R.drawable.ic_arrow_right).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
}
return super.onCreateOptionsMenu(menu);
}
I`m trying to request search from ActionBarSherlock.
My class extends SherlockListActivity.
This is how I`m adding Menu button to the ActionBar:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add("Save")
.setIcon(R.drawable.ic_action_search)
.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM |
MenuItem.SHOW_AS_ACTION_WITH_TEXT);
return true;
}
The problem is that I am unable to invoke it by id:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case ?????: {
onSearchRequested();
return true;
}
}
return true;
}
How people usually solve this problem?
Thanks.
If you inflate you menu from an XML menu file you will set an id which you can then use in your onOptionsItemSelected method. Like this:
XML
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/menu_search"
android:icon="#drawable/ic_menu_search"
android:showAsAction="ifRoom"
android:actionViewClass="android.widget.SearchView" android:title="#string/search"/>
</menu>
Fragment
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_search:
onSearchRequested();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Also you can use
#Override
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
menu.add(0, 1, 1, "Refresh").setIcon(R.drawable.ic_refresh).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
menu.add(0, 2, 2, "Search").setIcon(R.drawable.ic_search).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item) {
switch (item.getItemId()){
case 1:
...
break;
case 2:
...
break;
}
return true;
}
there is an activity in my android application. I override the 'onCreateOptionsMenu' method, adding four menu items in the activity. But the menu items do not display. I can not figure out what is the problem. Could somebody give me an clue to fix that or explaination?
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, FeaturedActivity.MENU_FEATURED, 0, R.string.menu_featured).setIcon(R.drawable.icon_tabbar_featured);
menu.add(0, FeaturedActivity.MENU_THE_DRINK, 1, R.string.menu_the_drink).setIcon(R.drawable.icon_tabbar_drinks);
menu.add(0, FeaturedActivity.MENU_PLAYER, 2, R.string.menu_player).setIcon(R.drawable.icon_tabbar_player);
menu.add(0, FeaturedActivity.MENU_SHARE, 3, R.string.menu_share).setIcon(R.drawable.icon_tabbar_share);
return true;
}
in your activity use
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.optionsmenu, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.info:
startActivity(new Intent(this, AboutApp.class));
return true;
case R.id.exit:
finish();
return true;
}
return false;
}
and create a folder menu in res and now create an xml in res/menu like optionsmenu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/info" android:title="Info"
android:icon="#drawable/info_menubtn" />
<item android:id="#+id/exit" android:title="Exit" />
</menu>
Hope this will work for you
remove the line super.onCreateOptionsMenu(menu); and try .
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
menu.add("this is menu");
menu.add("this is another");
return super.onCreateOptionsMenu(menu);
}
edit into above code and add return super.onCreateOptionsMenu(menu); at last and remove it from first line
Here I tried to make option menu, but menu is not displaying on screen, so please guide me where am I doing mistake...
MenuTest.java
public class MenuTest extends Activity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater=getMenuInflater();
inflater.inflate(R.menu.more_tab_menu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId())
{
case R.id.feeds:
break;
case R.id.friends:
break;
case R.id.about:
break;
}
return true;
}
}
And my XML file is more_tab_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/feeds"
android:title="Feeds"/>
<item
android:id="#+id/friends"
android:title="Friends"/>
<item
android:id="#+id/about"
android:title="About"/>
</menu>
Please guide me,
public class MenuTest extends Activity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.more_tab_menu, menu);
// return true so that the menu pop up is opened
return true;
}
}
and don't forget to press the menu button or icon on Emulator or device
please see :==
private int group1Id = 1;
int homeId = Menu.FIRST;
int profileId = Menu.FIRST +1;
int searchId = Menu.FIRST +2;
int dealsId = Menu.FIRST +3;
int helpId = Menu.FIRST +4;
int contactusId = Menu.FIRST +5;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(group1Id, homeId, homeId, "").setIcon(R.drawable.home_menu);
menu.add(group1Id, profileId, profileId, "").setIcon(R.drawable.profile_menu);
menu.add(group1Id, searchId, searchId, "").setIcon(R.drawable.search_menu);
menu.add(group1Id, dealsId, dealsId, "").setIcon(R.drawable.deals_menu);
menu.add(group1Id, helpId, helpId, "").setIcon(R.drawable.help_menu);
menu.add(group1Id, contactusId, contactusId, "").setIcon(R.drawable.contactus_menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 1:
// write your code here
Toast msg = Toast.makeText(MainHomeScreen.this, "Menu 1", Toast.LENGTH_LONG);
msg.show();
return true;
case 2:
// write your code here
return true;
case 3:
// write your code here
return true;
case 4:
// write your code here
return true;
case 5:
// write your code here
return true;
case 6:
// write your code here
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Change your onCreateOptionsMenu method to return true. To quote the docs:
You must return true for the menu to be displayed; if you return false it will not be shown.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
new MenuInflater(this).inflate(R.menu.folderview_options, menu);
return (super.onCreateOptionsMenu(menu));
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.locationListRefreshLocations) {
Cursor temp = helper.getEmployee(active_employeeId);
String[] matches = new String[1];
if (temp.moveToFirst()) {
matches[0] = helper.getEmployerID(temp);
}
temp.close();
startRosterReceiveBackgroundTask(matches);
} else if (item.getItemId()==R.id.locationListPrefs) {
startActivity(new Intent(this, PreferencesUnlockScreen.class));
return true;
}
return super.onOptionsItemSelected(item);
}
you can create options menu like below:
Menu XML code:
<?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/Menu_AboutUs"
android:icon="#drawable/ic_about_us_over_black"
android:title="About US"/>
<item
android:id="#+id/Menu_LogOutMenu"
android:icon="#drawable/ic_arrow_forward_black"
android:title="Logout"/>
</menu>
How you can get the menu from MENU XML(Convert menu XML to java):
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.my_options_menu,menu);
return super.onCreateOptionsMenu(menu);
}
How to get Selected Item from Menu:
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()){
case R.id.Menu_AboutUs:
//About US
break;
case R.id.Menu_LogOutMenu:
//Do Logout
break;
}
return super.onOptionsItemSelected(item);
}
import android.app.Activity;
import android.os.Bundle;
import android.view.*;
import android.widget.*;
public class AndroidWalkthroughApp2 extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// show menu when menu button is pressed
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// display a message when a button was pressed
String message = "";
if (item.getItemId() == R.id.option1) {
message = "You selected option 1!";
}
else if (item.getItemId() == R.id.option2) {
message = "You selected option 2!";
}
else {
message = "Why would you select that!?";
}
// show message via toast
Toast toast = Toast.makeText(this, message, Toast.LENGTH_LONG);
toast.show();
return true;
}
}
Replace return super.onCreateOptionsMenu(menu); with return true; in your onCreateOptionsMenu method
This will help
And you should also have the onCreate method in your activity
The previous answers have covered the traditional menu used in android. Their is another option you can use if you are looking for an alternative
https://github.com/AnshulBansal/Android-Pulley-Menu
Pulley menu is an alternate to the traditional Menu which allows user to select any option for an activity intuitively. The menu is revealed by dragging the screen downwards and in that gesture user can also select any of the options.
Android UI programming is a little bit tricky. To enable the Options menu, in addition to the code you wrote, we also need to call setHasOptionsMenu(true) in your overriden method OnCreate().
Hope this will help you out.
IF your Device is running Android v.4.1.2 or before,
the menu is not displayed in the action-bar.
But it can be accessed through the Menu-(hardware)-Button.
Good Day
I was checked
And if You choose Empty Activity
You Don't have build in Menu functions
For Build in You must choose Basic Activity
In this way You Activity will run onCreateOptionsMenu
Or if You work in Empty Activity from start
Chenge in styles.xml the
