Handling Click Event for menu Used for Floating Action Button Options

I used a library recently that Provides a Floating Action Button and changing to a Something like Navigation bar by clicking on it.
but i cant set click Event for my navigation bar Items.
after Pressing on items i don't see any reaction!
Anyone can help me?
fabOptions = (FabOptions) findViewById(R.id.fabcontainer);
fabOptions.setButtonsMenu(R.menu.menu1);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu1, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.back:
newBack();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private void newBack() {
Toast.makeText(this, "back", Toast.LENGTH_SHORT).show();
}
}

First of all you should have to use break whenever you use switch statement otherwise the program will go to default status. so use break; the code below.
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getId(); // Retrieve the id of the selected menu item
switch(id) {
case R.id.back:
newBack();
return true;
break;
case ...
}
return super.onOptionsItemSelected(item);
}

How to use on click listener on menu items?

Instead of using toast , i want to use on click listener in the menu items, and can we use fragments in this case
this is the following code in which i want to add on click, so i can open in a new activity
// Initiating Menu XML file (menu.xml)
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.layout.menu, menu);
return true;
}
/**
* Event Handling for Individual menu item selected
* Identify single menu item by it's id
* */
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.menu_bookmark:
// Single menu item is selected do something
// Ex: launching new activity/screen or show alert message
Toast.makeText(AndroidMenusActivity.this, "Bookmark is Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.menu_save:
Toast.makeText(AndroidMenusActivity.this, "Save is Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.menu_search:
Toast.makeText(AndroidMenusActivity.this, "Search is Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.menu_share:
Toast.makeText(AndroidMenusActivity.this, "Share is Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.menu_delete:
Toast.makeText(AndroidMenusActivity.this, "Delete is Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.menu_preferences:
Toast.makeText(AndroidMenusActivity.this, "Preferences is Selected", Toast.LENGTH_SHORT).show();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}

Yes you can do that by simply adding an Intent against each menu item within switch case. Have a look on the below snippet for your reference:
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.menu_bookmark:
// Ex: launching new activity/screen or show alert message
Intent intent = new Intent(yourActivity.this, NextActivity.class)
startActivity(intent);
return true;
default:
return super.onOptionsItemSelected(item);
}
}

#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.menu_bookmark:
Intent intent = new Intent(currentactivity.this, toactivity.class)
startActivity(intent);
return true;
case R.id.menu_save:
Intent intent = new Intent(currentactivity.this, toactivity.class)
startActivity(intent);
return true;
case R.id.menu_search:
Intent intent = new Intent(currentactivity.this, toactivity.class)
startActivity(intent);
return true;
case R.id.menu_share:
Intent intent = new Intent(currentactivity.this, toactivity.class)
startActivity(intent);
return true;
case R.id.menu_delete:
Intent intent = new Intent(currentactivity.this, toactivity.class)
startActivity(intent);
return true;
case R.id.menu_preferences:
Intent intent = new Intent(currentactivity.this, toactivity.class)
startActivity(intent);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Intent
You have to use intent for moving from one screen to another
Intent intent = new Intent(currentactivity.this,towhichactivityyouwantmove.class)
startActivity(intent);

Item ID of title ActionBar

look this image:
When you click on the "Action bar" string my app enter in this method:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.action_search:
openSearch();
return true;
case R.id.action_settings:
openSettings();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
So also it is an item, the problem is that i don't know which id it has.
Where can i get the id of this item ?

android.R.id.home
if you have set
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true)‌​;

Try this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.action_search:
openSearch();
return true;
case R.id.action_settings:
openSettings();
return true;
case android.R.id.home:
//here you put your code
Toast.makeText(this, "You click Action Bar", Toast.LENGTH_SHORT).show();
return true;
default:
return super.onOptionsItemSelected(item);
}
}

How can I change some text in an ActionBar item after an onOptionItemSelected event?

I'm using ActionBar in my application, and I want when the user clicks a button, the item in the ActionBar should change the text.
This is my code for onOptionsItemSelected():
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_refresh:
Toast.makeText(this, "Menu Item 1 selected", Toast.LENGTH_SHORT)
.show();
finish();
break;
case R.id.lg:
Toast.makeText(getBaseContext(), "ma", Toast.LENGTH_SHORT).show();
break;
case R.id.French:
Toast.makeText(getBaseContext(), "zaki", Toast.LENGTH_SHORT).show();
break;
case R.id.nerlandais:
Toast.makeText(getBaseContext(), "brahim", Toast.LENGTH_SHORT)
.show();
}
return true;
}
What must I do to change the item title from another item?
Example: When I click in French item I want to change nerlandais item title.

If you want to change an MenuItem's title clicking to another item you can do something like this :
private String mMenuItemTitle;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getSupportMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem item = menu.findItem(R.id.nerlandais);
item.setText(mMenuItemTitle);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.French:
Toast.makeText(getBaseContext(), "zaki", Toast.LENGTH_SHORT).show();
mMenuItemTitle = "My New Title";
supportInvalidateOptionsMenu();
break;
}
return true;
}

Try item.setTitle("new title")
Or, if from another item then the Menu has findItem

menuEdit.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
activity.openOptionsMenu(); //This is the key method!
}
});
public boolean onCreateOptionsMenu(Menu menu) {
com.actionbarsherlock.view.MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
public boolean onMenuItemClick(MenuItem item) {
switch (item.getItemId()) {
case R.id.demographics:
return true;
case R.id.settings:
Log.v("v", "settings clicked");
return true;
default:
return false;
