hello i have created a menu with onCreateOptionsMenu . Here is the code :
public boolean onCreateOptionsMenu(Menu menu) {
boolean result = super.onCreateOptionsMenu(menu);
menu.add(0, INSERT_ID, 0, R.string.menu_insert);
return result;
}
It works fine but the string menu_insert is displayed in the far left side of the pop up menu. Is there a way to align the string to the center? sorry if it is a newbie question.
Thanks a lot in advance!
You should use the xml to create a menu and on top of that you can use the ActionBar, read here

I am using ActionBarSherlock in my application and I want to implement popup menu like the below image, having a logo and respective text.
Please help me to achieve this, any help would be appreciable.
Thanks
Here it is.This is actually done in the app which you posted screenshot for.I think you are familiar with ActionbarSherlok.The button for this dropdown menu will be on actionbar.
public boolean onCreateOptionsMenu(Menu menu) {
// Used to put dark icons on light action bar
SubMenu subMenu1 = menu.addSubMenu("");
subMenu1.add("Item1").setIcon(R.drawable.icon).setOnMenuItemClickListener(
new OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
return false;
}
});
MenuItem subMenu1Item = subMenu1.getItem();
subMenu1Item.setIcon(R.drawable.abs__ic_menu_moreoverflow_holo_dark);
subMenu1Item.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS
| MenuItem.SHOW_AS_ACTION_WITH_TEXT);
return true;
}
Added PopupMenu in ActionBarSherlock.
I have a basic problem where an initially hidden MenuItem is unable to be toggled to visible. As a caveat, I am using ActionBarSherlock, but I wanted to see if anyone knew if this was a known issue of Android or I am doing something terrible before investigating whether this is an issue inside of ABS. Code as follows:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.menu_xml, menu);
mMenuItem = menu.findItem(R.id.menu_item);
mMenuItem.setVisible(false);
return true;
}
// Somewhere elsewhere
// MenuItem is never visible after this line is executed
mMenuItem.setVisible(true);
I have also tried to move the mMenuItem assignment and visibility into a call to onPrepareOptionsMenu but the same behavior is shown.
Thanks!
The problem is you are not telling Android that it needs to update the menu. This drove me nuts for the last hour until I figured out a solution. I don't think it's as apparent on pre-HC because menu items aren't always visible on the screen like they are in HC+.
On your activity, simply call:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
this.invalidateOptionsMenu();
}
That will trigger a call to the onCreateOptionsMenu() event again, so if you're setting the visibility in that function for initialization you'll need to take into account then if you want the option to show or not.
I had the same problem and I found out that setVisible(true) works when there is at least another MenuItem visible. I hope this can be helpful to someone.
I understand this is old question.
But I've solved it by placing inside onPrepareOptionMenu() {...}
private boolean mShowVisible=false;
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
menu.findItem(R.id.menu_item).setVisible(mShowVisible);
return super.onPrepareOptionsMenu(menu);
}
whenever you want to set visible or not just call it as:
mShowVisible = true; // or false
invalidateOptionMenu();
I found that using a view's post(Runnable) method to setVisible does the trick, so something like...
view.post(new Runnable() {
#Override
public void run() {
menu.findItem(id).setVisible(true);
}
});
How can I add an Action Bar Item during run time?
I am using actionBarSherlock, and I need to add some buttons when an event occurs (get some texts from a RSS, for example). I can't rely on a fixed xml.
You can create the menu in code like this:
/*************************************/
/* Create the actionbar options menu */
/*************************************/
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
menu.add(0, 0, 0, "History").setIcon(R.drawable.ic_menu_recent_history)
.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
menu.add(0, 1, 0, "Settings").setIcon(R.drawable.ic_menu_manage)
.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
return true;
}
Inside check for a boolean.
You will need to call supportInvalidateOptionsMenu() to recreate the menu.
You can maintain a flag that determines if you need to display your button
boolean hasRss = false;
then, override the method onCreateOptionsMenu(Menu menu) and check to see if hasRss is true or false. If true, add your button to do whatever. Then you can add your normal buttons you want to always show up regardless if you have the RSS or not
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
if (hasRss)
{
menu.add(Menu.NONE, 0, Menu.NONE, "View RSS").setIcon(R.drawable.ic_menu_view)
.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
}
menu.add(Menu.NONE, 1, Menu.NONE, "Normal button that is always there").setIcon(R.drawable.ic_menu_button)
.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
}
you will have to set your hasRss value = true whenever you retrieve your values and call invalidateOptionsMenu(); to reload the action bar menu items
Can anyone point in the direction of any tutorials that show how to create an options menu with clicakble checks like in the picture below:
alt text http://img291.imageshack.us/img291/1221/deviceit.png
I have tried as follows:
/** Menu creation and setup **/
/* Creates the menu items */
public boolean onCreateOptionsMenu(Menu menu) {
boolean result = super.onCreateOptionsMenu(menu);
menu.add(0, 1, 0, "Speaker").setCheckable(true);
menu.add(0, 2, 0, "Mute").setCheckable(true);
return result;
}
/* Handles item selections */
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 1:
if(audioManager.isSpeakerphoneOn()==false){
audioManager.setSpeakerphoneOn(true);
audioManager.setRouting(AudioManager.MODE_IN_CALL,
AudioManager.ROUTE_SPEAKER, AudioManager.ROUTE_ALL);
}else{
audioManager.setSpeakerphoneOn(false);
audioManager.setRouting(AudioManager.MODE_IN_CALL,
AudioManager.ROUTE_EARPIECE, AudioManager.ROUTE_ALL);
}
return true;
case 2:
if(audioManager.isMicrophoneMute())
audioManager.setMicrophoneMute(false);
else
audioManager.setMicrophoneMute(true);
return true;
}
return false;
}
But this doesn't work it only gives me text on the buttons on the options menu
EDIT: I have added the following onPrepareOptionsMenu method:
public boolean onPrepareOptionsMenu(Menu menu){
boolean result = super.onPrepareOptionsMenu(menu);
if(audioManager.isSpeakerphoneOn())
menu.findItem(1).setChecked(true);
else
menu.findItem(1).setChecked(false);
if(audioManager.isMicrophoneMute())
menu.findItem(2).setChecked(true);
else
menu.findItem(2).setChecked(false);
return result;
}
However I get the same outcome just text and no check light as in the picture above
If you want to change dynamically the state of your Option Menu, you need to use onPrepareMenu(). In this method, you can do dynamic checks and update anything you want.
Good luck!!

After some digging, this look like a custom view. I think your picture comes from this code.
This is an old question, but I had the same problem and searched a lot to find such an optionsMenu shown above. I found a tutorial on http://www.codeproject.com and modified it a little bit. Maybe it is not a profi-programmers-code, but it works for me. See my modifications at my (poor arranged) web page on google sites (I got an little tutorial too on this site):
https://sites.google.com/site/opiatefuchs/android-code-examples
This code is original from wjfrancis on the Code Project web page (many props):
http://www.codeproject.com/Articles/173121/Android-Menus-My-Way
I just modified it and would be glad if somebody got any ideas to improve this code. But for now, it works.
I need a very simple menu which probably contains only one or two items: settings/options, where pressing one of them should show some customer defined parameters (is it called dialog), e.g., number of results shown. Is there any good tutorial on creating such kind of menus? I've looked at the "notepad" example in android, it doesn't really help.
Depending on what you're asking for, these are either "Options Menus" or "Context Menus", and creating them is very easy. Here's a link to the page on the Developers' Website explaining how to do menus.
Here's a basic example of code for options menus, adapted from my game:
public boolean onCreateOptionsMenu(Menu menu){
// Define your menu, giving each button a unique identifier numbers
// (MENU_PAUSE, etc)
// This is called only once, the first time the menu button is clicked
menu.add(0, MENU_PAUSE, 0, "Pause").setIcon(android.R.drawable.ic_media_pause);
menu.add(0, MENU_RESUME, 0, "Resume").setIcon(android.R.drawable.ic_media_play);
return true;
}
public boolean onPrepareOptionsMenu(Menu menu){
// This is called every time the menu button is pressed. In my game, I
// use this to show or hide the pause/resume buttons depending on the
// current state
}
public boolean onOptionsItemSelected(MenuItem item){
// and this is self explanatory
boolean handled = false;
switch (item.getItemId()){
case MENU_PAUSE:
pauseGame();
handled = true;
break;
case MENU_RESUME:
resumeGame();
handled = true;
break;
}
return handled;
}
Edit: See the comments for some details on AlertDialogs
