I have an activity in an android app with fragments displayed using a pager.
One of the three fragments shows a menu item (always displayed as action) and an overflow menu, the two others fragments show in the app bar only the first menu item (but not the overflow menu).
My problem is that when I switch from one tab to another, the menu is not updating smoothly.
Is it possible to add animations to menu inflation ?
Has anyone ever encountered such an issue and how did you handle it ?
Here is the app bar :
And here is how I inflate the menu inside the fragment, of course, the other fragment is inflating another XML file.
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.home_menu, menu);
}
Please feel free to ask for more details ;-)
Thanks for helping !
In you fragment please write this line in your oncreateview mehod:
setHasOptionsMenu(true);
and implement this mehod:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_referesh, menu);
super.onCreateOptionsMenu(menu,inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.refresh:
pageNumber=1;
getWebServiceData1();
return false;
}
return super.onOptionsItemSelected(item);
}
I have MainActivity and it's have fragment. I added toolbar from MainActivity;
MainActivity
private Toolbar mToolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mToolbar = (Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
When I was open any fragment from MainActivity then that fragment use own menu file
In fragment
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.custom_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
As you can see above I inflated custom menu in onCreateOptionsMenu. But It doesn't work.
after
toolbar.getMenu().clear();
add toolbar.inflateMenu(R.menu.menu_blank);
and I am not set toolbar as acionbar,Maybe you should user getActionbar to do something.
I'm not entirely sure this is what you're asking but I think you want to be able to change the options in the menu, dynamically. You can do the following
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
if (mHideSomething) {
MenuItem myItem = menu.findItem(R.id.action_something);
myItem.setVisible(false);
} //otherwise it will show as usual
return true;
}
Then when you want to change something in the menu...
mHideSomething = true;
supportInvalidateOptionsMenu();
EDIT
Now I understand you're just adding odd behaviour when overriding. You can still do the following (although it seems like these items just shouldn't be part of main menu if they're not relevant always)
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.custom_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
MenuItem mainMenuItemToRemove = menu.findItem(R.id.action_something);
mainMenuItemToRemove .setVisible(false);
}
The only problem with the above is it makes assumptions about what is available in the main menu even though the fragment should be reusable. A better solution would be to pass in an interface to the fragment to call back to the activity and let the activity have control. Better still, update the activity logic and never inflate the main menu at all if not required.
I want to have completely different menu options in different fragment.I followed this post.But my fragment menu is adding with the activity menu.But i don't want to have activity menus in some of my fragments.
In SlidingDrawerActivity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
In my fragment:
public Friends_Status_Comment_Fragment(){
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_add_comment,menu);
super.onCreateOptionsMenu(menu, inflater);
}
The Activities items are adding with the menu of fragment.How to stop it???
I'm not sure if I underestand your problem - in your fragment you should clear menu and create new one - and don't call super :) something like this:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater){
menu.clear();
inflater.inflate(R.menu.menu_add_comment,menu);
}
I have implemented ActionBar Navigation using Fragment. In my App i have one Activity and rest is in Fragments. In my MainActivity i am implementing menu like this.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
Two Fragments uses Navigation Drawer and in their respected fragments i am inflating menu buttons to sort items.
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.sort_button_shops, menu);
}
Now the Problem is if i open the Fragment 1 it works perfectly. When i open fragment 2, it shows 2 button to sort, one from Fragment 1 and the second one from Fragment 2.
I have tried to hide the button but it didn't worked.
Any Help will be Appreciated.
Thanks
When you inflate a new menu you are adding new items to the old Menu object, which is probably not what you intended.
Try this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.removeItem(R.id.your_menu_item);
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
Try using this in onResume() of fragments.
MenuItem item = (MenuItem) findViewById(R.menu.activity_main);
item.setVisible(false);
this.invalidateOptionsMenu();
I have a Sherlock Fragment Activity in which there are 3 Fragments.
Fragment A, Fragment B, Fragment C are three fragments. I want to show a done option menu in Fragment B only.
And the activity is started with Fragment A. When Fragment B is selected done button is added.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
if(!menusInflated){
inflater.inflate(R.menu.security, menu);
menusInflated=true;
}
super.onCreateOptionsMenu(menu, inflater);
}
When I again start Fragment A I want to options Menu DONE (which was set at Fragment B) for this I am doing like this
setHasOptionsMenu(false);
MenuItem item = (MenuItem) menu.findItem(R.id.done_item);
item.setVisible(false);
But this is not hiding at all, also it is giving NullPointerException when Activity if first started with Fragment A.
Please let me know what is the problem.
Try this...
You don't need to override onCreateOptionsMenu() in your Fragment class again. Menu items visibility can be changed by overriding onPrepareOptionsMenu() method available in Fragment class.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onPrepareOptionsMenu(Menu menu) {
menu.findItem(R.id.action_search).setVisible(false);
super.onPrepareOptionsMenu(menu);
}
This is one way of doing this:
add a "group" to your menu:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<group
android:id="#+id/main_menu_group">
<item android:id="#+id/done_item"
android:title="..."
android:icon="..."
android:showAsAction="..."/>
</group>
</menu>
then, add a
Menu menu;
variable to your activity and set it in your override of onCreateOptionsMenu:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
this.menu = menu;
// inflate your menu here
}
After, add and use this function to your activity when you'd like to show/hide the menu:
public void showOverflowMenu(boolean showMenu){
if(menu == null)
return;
menu.setGroupVisible(R.id.main_menu_group, showMenu);
}
I am not saying this is the best/only way, but it works well for me.
To show action items (action buttons) in the ActionBar of fragments where they are only needed, do this:
Lets say you want the save button to only show in the fragment where you accept input for items and not in the Fragment where you view a list of items, add this to the OnCreateOptionsMenu method of the Fragment where you view the items:
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
if (menu != null) {
menu.findItem(R.id.action_save_item).setVisible(false);
}
}
NOTE: For this to work, you need the onCreate() method in your Fragment (where you want to hide item button, the item view fragment in our example) and add setHasOptionsMenu(true) like this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
Might not be the best option, but it works and it's simple.
This will work for sure I guess...
// Declare
Menu menu;
MenuItem menuDoneItem;
// Then in your onCreateOptionMenu() method write the following...
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
this.menu=menu;
inflater.inflate(R.menu.secutity, menu);
}
// In your onOptionItemSelected() method write the following...
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.done_item:
this.menuDoneItem=item;
someOperation();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
// Now Making invisible any menu item...
public void menuInvisible(){
setHasOptionsMenu(true);// Take part in populating the action bar menu
menuDoneItem=(MenuItem)menu.findItem(R.id.done_item);
menuRefresh.setVisible(false); // make true to make the menu item visible.
}
//Use the above method whenever you need to make your menu item visible or invisiable
You can also refer this link for more details, it is a very useful one.
MenuItem Import = menu.findItem(R.id.Import);
Import.setVisible(false)
Try this
#Override
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.custom_actionbar, menu);
menu.setGroupVisible(...);
}
By setting the Visibility of all items in Menu, the appbar menu or overflow menu will be Hide automatically
Example
private Menu menu_change_language;
...
...
#Override
public boolean onCreateOptionsMenu(Menu menu) {
...
...
menu_change_language = menu;
menu_change_language.findItem(R.id.menu_change_language).setVisible(true);
return super.onCreateOptionsMenu(menu);
}
Before going to other fragment use bellow code:
if(menu_change_language != null){
menu_change_language.findItem(R.id.menu_change_language)
.setVisible(false);
}
Hello I got the best solution of this, suppose if u have to hide a particular item at on create Menu method and show that item in other fragment. I am taking an example of two menu item one is edit and other is delete. e.g menu xml is as given below:
sell_menu.xml
<?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/action_edit"
android:icon="#drawable/ic_edit_white_shadow_24dp"
app:showAsAction="always"
android:title="Edit" />
<item
android:id="#+id/action_delete"
android:icon="#drawable/ic_delete_white_shadow_24dp"
app:showAsAction="always"
android:title="Delete" />
Now Override the two method in your activity & make a field variable mMenu as:
private Menu mMenu; // field variable
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.sell_menu, menu);
this.mMenu = menu;
menu.findItem(R.id.action_delete).setVisible(false);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.action_delete) {
// do action
return true;
} else if (item.getItemId() == R.id.action_edit) {
// do action
return true;
}
return super.onOptionsItemSelected(item);
}
Make two following method in your Activity & call them from fragment to hide and show your menu item. These method are as:
public void showDeleteImageOption(boolean status) {
if (menu != null) {
menu.findItem(R.id.action_delete).setVisible(status);
}
}
public void showEditImageOption(boolean status) {
if (menu != null) {
menu.findItem(R.id.action_edit).setVisible(status);
}
}
That's Solve from my side,I think this explanation will help you.
You can make a menu for each fragment, and a global variable that mark which fragment is in use now.
and check the value of the variable in onCreateOptionsMenu and inflate the correct menu
#Override
public boolean onCreateOptionsMenu(Menu menu) {
if (fragment_it == 6) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.custom_actionbar, menu);
}
}
Okay I spend couple of hour to get this solution.apparently you can get menuitem from your toolbar to anywhere in activity or fragment. So in my case.
var menuItem = toolbar.menu;
Now to get specfic item from menu item
favIcon = menuItem.findItem(R.id.favourite);
Note: favIcon is MenuItem declare global
Now if you can do whatever you want to do for this icon
eg. to make it invisible
favIcon?.isVisible=false
Even though the question is old and answered. There is a simpler answer to that than the above mentioned. You don't need to use any other variables.
You can create the buttons on action bar whatever the fragment you want, instead of doing the visibility stuff(show/hide).
Add the following in the fragment whatever u need the menu item.
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
Sample menu.xml file:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_addFlat"
android:icon="#drawable/add"
android:showAsAction="ifRoom|withText"
android:title="#string/action_addFlat"/>
</menu>
Handling onclick events is as usual.
Late to the party but the answers above didn't seem to work for me.
My first tab fragment (uses getChildFragmentManager() for inner tabs) has the menu to show a search icon and uses android.support.v7.widget.SearchView to search within the inner tab fragment but navigating to other tabs (which also have inner tabs using getChildFragmentManager()) would not remove the search icon (as not required) and therefore still accessible with no function, maybe as I am using the below (ie outer main tabs with each inner tabs)
getChildFragmentManager();
However I use the below in my fragments containing/using the getChildFragmentManager() for inner tabs.
//region onCreate
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRetainInstance(true);
//access setHasOptionsMenu()
setHasOptionsMenu(true);
}
//endregion onCreate
and then clear the menu item inside onPrepareOptionsMenu for fragments(search icon & functions)
#Override
public void onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu(menu);
//clear the menu/hide the icon & disable the search access/function ...
//this will clear the menu entirely, so rewrite/draw the menu items after if needed
menu.clear();
}
Works well and navigating back to the tab/inner tab with the search icon functions re displays the search icon & functions.
Hope this helps...
For some reason the method was not working for me this is how I solved it according to the accepted solution
//This should be in on create
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
showOverflowMenu(false);
}
},100);
#Override
public boolean onCreateOptionsMenu(Menu menu) {
this.menu = menu;
getMenuInflater().inflate(R.menu.options_menu, menu);
return true;
}
public void showOverflowMenu(boolean showMenu){
if(menu == null)
return;
menu.setGroupVisible(R.id.grp, showMenu);
}
