I have two different Menu items (Flipping and Sharing) that share a single activity. Each one of them, works perfectly and smooth by its own, but when I put them together, the flipping action takes too long to respond. What can I do? Thanks for your help.
Flipping action:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
// Add either a "photo" or "finish" button to the action bar, depending on which page
// is currently selected.
MenuItem item = menu.add(Menu.NONE, R.id.action_flip, Menu.NONE,
mShowingBack
? R.string.action_photo
: R.string.action_info);
item.setIcon(mShowingBack
? R.drawable.ic_action_photo
: R.drawable.ic_action_info);
item.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
return true;
}
Share Action
public boolean onPrepareOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.share_menu, menu);
MenuItem item = menu.findItem(R.id.menu_item_share);
mShareActionProvider = (ShareActionProvider) item.getActionProvider();
mShareActionProvider.setShareIntent(getDefaultShareIntent());
return super.onPrepareOptionsMenu(menu);
}
I left this question open, and I forgot about it. However, I took a look again and remember how I solve it. I was doing it all wrong. I had to call super.onPrepareOptionsMenu(menu) before everything like this:
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu(menu);
getMenuInflater().inflate(R.menu.share_menu, menu);
MenuItem item = menu.findItem(R.id.menu_item_share);
mShareActionProvider = (ShareActionProvider) item.getActionProvider();
mShareActionProvider.setShareIntent(getDefaultShareIntent());
return true;
}

my application provides a list of recipes
at first all recipes are meat based and on the click of a switch in the setting page they become vegetable based
i want my app to change the titles and icons of the menu from meat based to vegetable based
i have put this code in the onPrepareOptionsMenu and it is being called but the titles are not being updated
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
super.onCreateOptionsMenu(menu);
final MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.activity_main_drawer, menu);
return true;
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
if (Build.VERSION.SDK_INT > 11) {
invalidateOptionsMenu();
MenuItem item1 = menu.findItem(R.id.nav_all);
MenuItem item2 = menu.findItem(R.id.nav_beef);
MenuItem item4 = menu.findItem(R.id.nav_chicken);
Log.d("ISVEG", MeApplication.getIsVeg().toString());
if (MeApplication.getIsVeg()) {
item1.setTitle("Omlets");
item1.setIcon(ContextCompat.getDrawable(this, R.drawable.eggs));
item2.setTitle("Broccoli");
item2.setIcon(ContextCompat.getDrawable(this, R.drawable.broccoli));
item4.setTitle("Tomato");
item4.setIcon(ContextCompat.getDrawable(this, R.drawable.tomato));
} else {
item1.setTitle("All meat");
item1.setIcon(ContextCompat.getDrawable(this, R.drawable.allmeat));
item2.setTitle("Beef");
item2.setIcon(ContextCompat.getDrawable(this, R.drawable.steak));
item4.setTitle("Chicken");
item4.setIcon(ContextCompat.getDrawable(this, R.drawable.thanksgiving));
}
}
return super.onPrepareOptionsMenu(menu);
}
Remove invalidateOptionsMenu(); from onPrepareOptionsMenu. Its not required since onPrepareOptionsMenu will prepare the Screen's standard options menu to be displayed. This is called right before the menu is shown, every time it is shown
How can I get an icon from the toolbar to be changed to a new one that I get with a method that is seen in a bbdd.
The problem is that I can not access the event that updates the activity to be able to change the icon.
I tried with the onPrepareOptionsMenu method, but I can not make it work.
I have not been able to do this by putting the code in onStart because it tells me that the menu object is empty or invalid.
public boolean onPrepareOptionsMenu(Menu menu) {
menu.clear();
Drawable iconoMenu = obtenerIconoMenuCarro();
getMenuInflater().inflate(R.menu.menu_categorias, menu);
menu.getItem(0).setIcon(iconoMenu);
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_categorias, menu);
Drawable iconoMenu = obtenerIconoMenuCarro();
menu.getItem(0).setIcon(iconoMenu);
return true;
}
My activities are extended by AppCompactActivity and loaded through an AdapterView.
And I have the problem when I go back to the fragmentDialog or since the next activity.
Thanks.
For me the simplest way was to keep a reference to the MenuItem for later use.
Obtain when the menu item is inflated.
MenuItem menuItem;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_menu, menu);
//find the menu item from the id
menuItem = menu.findItem(R.id.myMenuItem);
return true;
}
Then change the image where you need to with mipmap resource or #drawable.
menuItem.setIcon(R.mipmap.ic_other_icon);
I added a ShareActionProvider menu item to my add, but when I press the "Share" button, the onOptionsItemSelected function doesn't capture the event, and I don't succeed to capture the changes in the text (the shareContent is initialized with the onCreate data through the onCreateOptionsMenu function).
I found in old posts that in older versions (support.v7), the "MenuItemCompat" needed to be used, but it's not recognized in android.widget.ShareActionProvider class.
This is part of my code:
menu.xml:
<item
android:id="#+id/action_share"
android:title="#string/action_title_share"
android:actionProviderClass="android.widget.ShareActionProvider"
android:showAsAction="always" />
mainActivity:
#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, menu);
MenuItem shareItem = menu.findItem(R.id.action_share);
// Fetch and store ShareActionProvider
mShareActionProvider = (ShareActionProvider) shareItem.getActionProvider();
setShareIntent(createShareIntent());
return true;
}
#Override
public boolean onOptionsItemSelected (MenuItem item)
{
switch (item.getItemId() )
{
case R.id.action_share:
//share note content
noButtonWasPressed = false;
mShareActionProvider = (ShareActionProvider) item.getActionProvider();
setShareIntent(createShareIntent());
return true;
Any suggestions?
I have a ListActivity (SherlockListActivity) and its content can be dynamically changed by the user. When the content changes, the options menu should be replaced.
As I learned, instead of onCreateOptionsMenu I should use onPrepareOptionsMenu that is (supposed to be) called every time the user selects the menu.
This is called right before the menu is shown, every time it is shown.
I have the following code:
#Override
public boolean onPrepareOptionsMenu(Menu menu)
{
menu.clear();
if (UserOption == UserOption1)
getSupportMenuInflater().inflate(R.menu.menu_option1, menu);
else
getSupportMenuInflater().inflate(R.menu.menu_option2, menu);
return super.onPrepareOptionsMenu(menu);
}
It is called only once during debug, so I always have the same menu.
What should I set to make it work?
Create and prepare the options menu for changing and its item selection method
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
menu.clear();
MenuInflater inflater = getMenuInflater();
if(menuString=="red"){
inflater.inflate(R.menu.red_menu, menu);
}else if(menuString=="green"){
inflater.inflate(R.menu.green_menu, menu);
}
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.new_game:
return true;
case R.id.help:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Like whenever you want to change menu call
String menuString="red or green";
invalidateOptionsMenu();
Like others told, if you want to have static menu use onCreateOptionsMenu, and if you want to change its visibility dynamically use onPrepareOptionsMenu along with onCreateOptionsMenu
I would put a number on the button that represent the numbers of notify like facebooks app.
I follow the first example in this topic :
Actionbar notification count icon (badge) like Google has
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuItem item = menu.findItem(R.id.badge);
MenuItemCompat.setActionView(item, R.layout.feed_update_count);
notifCount = (Button) MenuItemCompat.getActionView(item);
notifCount.setText(String.valueOf(SingletonGrafica.getNumeroNotifica()));
return super.onCreateOptionsMenu(menu);
}
When I call :
MenuItem item = menu.findItem(R.id.badge);
I obtain NullPointer Exception.Anyone can help me?
You need to create the menu first:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the navigation_menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.navigation_menu, menu);
return true;
}
and if you want to update the menu you should do it in:
onPrepareOptionsMenu
if you want the onPrepareOptionsMenu function to be called again you can call invalidateOptionsMenu();
You can also add item from code
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuItem item = menu.add("Badge");MenuItemCompat.setActionView(item, R.layout.feed_update_count);
return true;
}
