I have navigation menu item. Currently I create it manually in onCreateOptionsMenu:
public boolean onCreateOptionsMenu(Menu menu) {
mLocations = getResources().getStringArray(R.array.locations);
Context context = getSupportActionBar().getThemedContext();
ArrayAdapter<CharSequence> list = ArrayAdapter.createFromResource(
context, R.array.locations, R.layout.sherlock_spinner_item);
list.setDropDownViewResource(R.layout.sherlock_spinner_dropdown_item);
getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
getSupportActionBar().setListNavigationCallbacks(list, this);
}
Is there a way to define it in XML ?
You need to do two things: One is to set up the xml and the second to inflate it. Here is main.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:showAsAction="never"
android:title="#string/action_settings"/>
<item
android:id="#+id/exit"
android:orderInCategory="200"
android:showAsAction="never"
android:title="#string/exit"/>
</menu>
Then, inflate the XML on the main activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getSupportMenuInflater().inflate(R.menu.main, menu);
return true;
}
If you are using fragments it should look something like this:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// Inflate the menu; this adds items to the action bar if it is present.
inflater.inflate(R.menu.fragment, menu);
}
and of course have a matching fragment.xml to go with it.
Good luck!

android.view.MenuItem.setVisible(true);
In onCreateOptionsMenu() my code is:
#Override public void onCreateOptionsMenu(final Menu menu, final MenuInflater inflater) {
mMenu = menu;
inflater.inflate(R.menu.contact_list_menu, menu);
}
In my function hideMenu() my code is:
mMenuItem.setVisible(false);
contact_list_menu.xml:
<menu xmlns:android="schemas.android.com/apk/res/android">
<item
android:id="#+id/action_reimport"
android:title="#string/reimport"
android:icon="#drawable/ic_reimport_contacts"
android:showAsAction="always"/>
</menu>
This is my menu xml file...
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/action"
android:icon="#drawable/ic_action_search_dark"
yourapp:showAsAction="always" /></menu>
here is my java code...
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.search, menu);
return true;
}
I want to add an action to the action bar, but it appears in my action bar as a drop down list.
How can I add button to the action bar?
My code is:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="Add"
showAsAction="ifRoom"/>
</menu>
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
If you are using android.app.Activity simply change showAsAction="always" to "android:showAsAction="always".
If you are using android.support.v7.app.Activity change the code as follows:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="Add"
app:showAsAction="ifRoom"/>
</menu>
You just simply add the one more item into menu and inflate that menu into your activity ....
like below you will add your button and access that button into your activity...
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/refresh"
android:icon="#android:drawable/stat_notify_sync"
showAsAction="ifRoom"/>
<item
android:id="#+id/action_bar_button_cancel"
android:focusableInTouchMode="true"
android:icon="#android:drawable/ic_menu_close_clear_cancel"
showAsAction="ifRoom"/>
</menu>
Inflating the menu like below.....
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
Accessing method in action bar item is....
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.refresh:
//logic
return true;
case R.id.action_bar_button_cancel:
//logic
return true;
default:
return super.onOptionsItemSelected(item);
}
}
that's if you have any doubt comment
I create base activity with actionbar menu functional and extended another activities from it.
public class BaseActivity extends SherlockFragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getSupportMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
...
return true;
}
}
Now I want to add some buttons to the actionbar in some activities. How can i add elements to actionbar and use element from base activity?
You can do that as simple as in BaseActivity just don't forget to call super.onCreateOptionsMenu().
main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_help"
android:icon="#drawable/ic_action_help"
android:title="#string/action_help" />
</menu>
home.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_new"
android:icon="#drawable/ic_action_new"
android:title="#string/action_new" />
</menu>
In BaseActivity you are using base menu config main.xml.
public class BaseActivity extends SherlockFragmentActivity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getSupportMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
In child activity you are using another config from home.xml only with additional menu items, no duplicates. But don't forget to call super.onCreateOptionsMenu(menu) with the same menu instance to add elements from BaseActivity (parent menu items would be added after child menu items if you call super's method after inflate, and before otherwise).
public class HomeActivity extends BaseActivity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getSupportMenuInflater().inflate(R.menu.home, menu);
return super.onCreateOptionsMenu(menu);
}
}
You can specify your actions for the actionbar in the main.xml
example :
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"/>
<item android:id="#+id/action_compose"
android:icon="#drawable/ic_action_compose"
android:title="#string/action_compose" />
And call from your subclass
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}
Make different xml files containing the buttons you need specific to those Activity. Say for Activity1 you have two buttons and for Activity2 you have one, then you will create 2 xml files like below.
action_activity1.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"/>
<item android:id="#+id/action_compose"
android:icon="#drawable/ic_action_compose"
android:title="#string/action_compose" />
</menu>
action_activity2.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"/>
</menu>
Then in the onCreateOptionsMenu(Menu menu) method inflate the desired xml file. Like,
Activity1:
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.action_activity1, menu);
return true;
}
Activity2:
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.action_activity2, menu);
return true;
}
Please be care full with the syntax (as I used appcompat actionbar). :)
This is what I use. Hope you find it helpful. And, I will be happy to see an easier way than this. :)
At my new application that I created, I got auto generated code for creating menu:
#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);
return true;
}
And I added item at menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:showAsAction="never"
android:title="#string/action_settings"/>
<item android:id="#+id/item1"></item>
</menu>
But there is no menu button, am I missing something?
EDIT:
In your menu definition you put:
android:showAsAction="never"
Change it to:
android:showAsAction="always"
Check this example, including an icon for the menu:
<item
android:id="#+id/menu_calendar"
android:title="#string/calendar"
android:icon="#drawable/ic_menu_calendar_holo_light"
android:showAsAction="always|withText" />
always means the button will always be displayed. You can replace it by ifRoom if it is a menu such as Settings that should appear in the menu as an option but not displayed all the time.
withtext means that the title of the menu will be displayed beside the icon if there is enough place for it.
Details about all these options are available here.
For the rest, you need to create and show the ActionBar in your onCreate() function:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//you might need this line if you are not using the Holo theme
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
setContentView(R.layout.main_activity);
ActionBar actionBar = getActionBar();
actionBar.show();
(...)
Check for the import you are using. Check example below
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuInflater;
...
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.menu, menu);
return super.onCreateOptionsMenu(menu);
}
You should use Menu and MenuInflater of actionbarsherlock..
Check out this link on implemention of ActionBarSherlock
Try
<item
android:id="#+id/action_settings"
android:showAsAction="always"
android:title="#string/action_settings"/>
<item android:id="#+id/item1"></item>
