How to make "my account or settings " clickable?

Here is the screen shot of my sidebar navigation bar.
I want to make the items in the sidebar navigation Menu clickable so that I can move to another Activity how can I do this?

You have to treat these as Menu items.
When you set up the navigation bar from the layout XML you attach a menu.xml to it which contains menu items that are then displayed in the navigation bar.
Method 1:
Now from the activity where you have your navigation bar variable you need to get the menu from the navigation view object.
Menu menu = navigation_view.getMenu();
Then you can get individual menuItems from this menu object.
MenuItem myAccount = menu.getItem(0);
MenuItem settingsItem = menu.getItem(1);
MenuItem logoutItem = menu.getItem(2);
Now you can use each of this menuItem objects to set menu click listeners on them and then start the next activity from there. e.g.
myAccount.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem menuItem) {
Intent intent = new Intent(context, ToAcitivity.class);
startActivity(intent);
return true;
}
});
Similarly, you can use rest of the objects and make them clickable.
Method 2:
You can also use
navigation_view.setNavigationItemSelectedListener(new
NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()){
case 1:
break;
case 2:
}
return false;
}
});
Second one being more simpler to use

How to change Navigation Item Selected programmatically

When I created a new project I used Navigation Drawer Activity
app screen
Now each menu item when I click on it will open a fragment by calling a method name replacement.
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_home) {
replaceFragment(0);
setTit = "Your State Info.";
setTitle(setTit);
} else if (id == R.id.nav_flashcards) {
replaceFragment(1);
setTit = "Flash Cards";
setTitle(setTit);
in fragment 1 I have a RadioGroup when the checked change will open the fragmet depends on the radio checked.
#Override
public void onCheckedChanged(RadioGroup radioGroup, int i) {
RadioButton radioButton = (RadioButton)getActivity().findViewById(i);
if(radioButton.getTag()==1)
((MainActivity) getActivity()).replaceFragment(0);
else if ((radioButton.getTag()==2))
((MainActivity) getActivity()).replaceFragment(2);
}
The App work fine , but the issue is how can I change the Navigation Item Selected and also change the title for the action bar.
it's possible to use this way
((MainActivity) getActivity()).onNavigationItemSelected(menuitem);
but from the fragment how can I access the the items in the menu>activity_main_drawer.xml and pass it through menuitem

This works for me..
NavigationView navigationView = (NavigationView) getActivity().findViewById(R.id.nav_view);
navigationView.getMenu().getItem(2).setChecked(true);

In your fragment you have to add setOptionsMenu(true)
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// TODO Add your menu entries here
super.onCreateOptionsMenu(menu, inflater);
}

question is not clear.
whole point of navigation drawer with fragments is to access navigation and its main toolbar all over the fragments with a single main activity.(the blue color one in your image, you should be able to change this anytime when you load a fragment)
But you need to make the frame/parent view of the fragments blow the tool bar view(that's why normally it comes with two XMLs, activtyMain.xml and contentMain.xml where content main is included below the tool bar in activityMain.XML) so you create fragments view match_parent to this contentMain.xml ,you can see toolbar is accessible to the each and every fragment you add in that view because its in the main activity where fragment/s add.
so you have a main activity and inside that you have fragment/s frame. Doesn't matter what fragment you load you can still have the access to main toolbar.
so once you check which item got clicked in navigationDrawer you load the fragment related to that right?. and there access the main toolbar of the mainActivity and do the changes that you need to display.That's it!
if (id == R.id.nav_whatever) {
// access toolBar or any view in main activity and do the changes
// call relevant fragment
}
But you cannot access that toolbar or mainActivity views inside your Fragment class that you try to attempt.
Edit :
Keep a Boolean in a Constant class or something similar,
then when you click on your button on second fragment change the value .
Now let's say Boolean is true
Then you click the navigation drawer again
// keep the id as it is and use the Boolean to check where you needs to go
if (id == R.id.nav_whatever) {
if(boolianName){
// boolianName is true go load second fragment
}else{
// load firstfragment
}
}

If you use Navegation drawer, you can use this code, put it on onCreate method:
NavigationView navigationView = (NavigationView) getActivity().findViewById(R.id.nav_view);
navigationView.getMenu().getItem(2).setChecked(true);

Add MenuItem to NavigationView programmatically - item not checked

I've added items to NavigationView programmatically:
**HERE ADD ITEMS**
Menu rightMenu = mRightDrawerView.getMenu();
for (DataParking dataParking : dataParkingList) {
MenuItem menuItem = rightMenu.add(dataParking.getTimeParking());
}
**HERE ADD CLICK LISTENER**
mRightDrawerView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
// Select menu
menuItem.setChecked(true);
// Closing left_drawer on item click
mDrawerLayout.closeDrawer(mRightDrawerView);
return false;
}
});
Items in navigation drawer are correctly clickable, but the selection is not persistent. If I add the same items via XML all works well.

When you are adding an item programmatically, the item's checkable flag is not set. You should just add this line:
menuItem.setCheckable(true);
after adding an item to menu.

As #Oncky answered, you can just setCheckable on your menuItem like this:
Menu rightMenu = mRightDrawerView.getMenu();
for (DataParking dataParking : dataParkingList) {
MenuItem menuItem = rightMenu.add(dataParking.getTimeParking()).setCheckable(true);
}

Toolbar menu item programmatic click

I have this code
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
openSearch();
return true;
}
});
into onCreate( ) of my Activity.
OpenSearch function call opens up google now like search view. This only happens when the user clicks on the search action item in the toolbar. In my case I want the search view to open up automatically when the activity starts. How can this menu item click be done programmatically.
I can't call openSearch directly because it needs the menu to be created.
Is there there any callbacks informing that action menus have been created ?

You can try something like this :
tollbarLayout.getViewTreeObserver().addOnGlobalLayoutListener(
new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
tollbarLayout.getViewTreeObserver().removeGlobalOnLayoutListener(this);
tollbar.performclick();
}
}
});

Android - toolbar and status bar as shared objects with content changes

In my app I set the toolbar and status bar as shared objects as suggested in option #2 in this post
The general behavior and outline of the toolbar and tabs are excellent - the only issue is that when I move to activity B, some of the UI elements of the Toolbar are not participating in the content transition, particularly the Toolbar title and the menu icons.
I tried adding a SharedElementCallback and in it to loop over the children of the toolbar and tabs and add them all to a Fade transition - but it didn't affect the behaviour of the toolbar and tab content.
Any idea how to proceed from here? The desired effect is to have the elements of the Toolbar (title, up button, menu icons) participate in the content transition.
Added screenshots after comment:
Activity A
Activity B

Each activity has your own menu, so you have to create the menu for each one, even if they are the same.
However, if you prefer, you can create just one menu and create a custom class for manipulate the menu; Then you call this custom class on onCreateOptionsMenu and onOptionsItemSelected from whatever activity.
The following code is an example.
Custom class:
public class MenuActionBar {
public static void createOptionsMenu(final Activity activity, Menu menu) {
activity.getMenuInflater().inflate(R.menu.yourmenu, menu);
// Do whatever you wanna do
}
public static boolean optionsItemSelected(Activity activity, MenuItem item) {
// Do whatever you wanna do
}
}
Activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuActionBar.createOptionsMenu(this, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return MenuActionBar.optionsItemSelected(this, item)
? true : super.onOptionsItemSelected(item);
}
