I have a calendar application. I am using ActionBarSherlock and Tabs. I have also implemented Options Menus in the Action Bar. I want one Menu Item in the Action Bar to behave differently when the tabs are selected.
How do I get the tab position in the onOptionsItemSelected(MenuItem item) method so based on that I can code the menu item accordingly?
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBar bar = getSupportActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.Tab Tab1 = bar.newTab();
ActionBar.Tab Tab2 = bar.newTab();
Tab1.setText("Tab1");
Tab2.setText("Tab2");
Tab1.setTabListener(new MyTabListener());
Tab2.setTabListener(new MyTabListener());
bar.addTab(Tab1);
bar.addTab(Tab2);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Intent newActivity;
// Handle item selection
switch (item.getItemId()) {
case android.R.id.home:
// app icon in action bar clicked; go home
newActivity = new Intent(this, Main.class);
newActivity.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(newActivity);
return true;
case R.id.menu_today_date:
//if condition here based on tabs selected
CalendarFragment frag = new CalendarFragment();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(android.R.id.content, frag);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
ft.commit();
return true;
case R.id.menu_prefs:
newActivity = new Intent(this, Settings.class);
startActivityForResult(newActivity, requestCode);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private class MyTabListener implements ActionBar.TabListener
{
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
if(tab.getPosition()==0)
{
CalendarFragment frag = new CalendarFragment();
ft.replace(android.R.id.content, frag);
}
else
{
ConverterFragment frag = new ConverterFragment();
ft.replace(android.R.id.content, frag);
}
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
}
I couldn't get the tab position, but this is how I ended up doing it:
private int tabSelected = 0;
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
if(tab.getPosition()==0)
{
tabSelected = 0;
CalendarFragment frag = new CalendarFragment();
ft.replace(android.R.id.content, frag);
}
else
{
tabSelected = 1;
ConverterFragment frag = new ConverterFragment();
ft.replace(android.R.id.content, frag);
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Intent newActivity;
// Handle item selection
switch (item.getItemId())
case R.id.menu_today_date:
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
if (tabSelected == 0){
CalendarFragment frag = new CalendarFragment();
ft.replace(android.R.id.content, frag);
}
else {
ConverterFragment frag = new ConverterFragment();
ft.replace(android.R.id.content, frag);
}
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.commit();
default:
return super.onOptionsItemSelected(item);
}
}

I have made the code to do that it loads fragment on clicking the items in the bottom navigation but when I click on it they don't work. I tried many times to check whats the problem even though Android Studio couldn't find it bu the app isn't working. I don't know whats the issue.
My main activity -
public class MainActivity extends AppCompatActivity {
BottomNavigationView btm_view;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = manager.beginTransaction();
fragmentTransaction.add(R.id.container, new Chats());
fragmentTransaction.commit();
btm_view = findViewById(R.id.bottom_view);
btm_view.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
if (item.getItemId() == R.id.camera) {
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = manager.beginTransaction();
fragmentTransaction.add(R.id.container, new Camera());
fragmentTransaction.commit();
} else if (item.getItemId() == R.id.chats) {
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = manager.beginTransaction();
fragmentTransaction.add(R.id.container, new Chats());
fragmentTransaction.commit();
} else if (item.getItemId() == R.id.status) {
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = manager.beginTransaction();
fragmentTransaction.add(R.id.container, new Status());
fragmentTransaction.commit();
} else if (item.getItemId() == R.id.calls) {
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = manager.beginTransaction();
fragmentTransaction.add(R.id.container, new Calls());
fragmentTransaction.commit();
} else if (item.getItemId() == R.id.settings) {
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = manager.beginTransaction();
fragmentTransaction.add(R.id.container, new Settings());
fragmentTransaction.commit();
}
return false;
}
});
}
}
one of my fragments -
public class Chats extends Fragment {
public Chats() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_chats, container, false);
}
}
Try this way
BottomNavigationView.OnNavigationItemSelectedListener navigationItemSelectedListener =
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.chats:
openFragment(Chat.newInstance());
return true;
case R.id.camera:
openFragment(Camera.newInstance());
return true;
case R.id.status:
openFragment(Status.newInstance("", ""));
return true;
}
return false;
}
};
At first use replace(R.id.container, fragment) instead of add.
Optimise Code
Utilise setOnNavigationItemSelectedListener. Try this way
Set a listener that will be notified when a bottom navigation item is
selected.
btm_view.setOnNavigationItemSelectedListener(navigationItemSelectedListener);
openFragment(Camera.newInstance());
}
public void openFragment(Fragment fragment) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.container, fragment);
transaction.addToBackStack(null);
transaction.commit();
}
BottomNavigationView.OnNavigationItemSelectedListener navigationItemSelectedListener =
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.camera:
openFragment(Camera.newInstance());
return true;
case R.id.chats:
openFragment(Chats.newInstance());
return true;
case R.id.status:
openFragment(Status.newInstance());
return true;
case R.id.calls:
openFragment(Calls.newInstance());
return true;
case R.id.settings:
openFragment(Settings.newInstance());
return true;
}
return false;
}
};
}
Your Chats Fragment will be
public class Chats extends Fragment {
public Chats() {
// Required empty public constructor
}
public static Chats newInstance() {
Chats fragment = new Chats();
return fragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_chats, container, false);
}
}
This is my code I have created a bottom navigation view and I am connected the items to fragment separately. When I click the the navigation item more time the fragment load again again.
I don't know what is the problem here.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomNavigationView bottomNav = findViewById(R.id.bottom_navigation);
bottomNav.setOnNavigationItemSelectedListener(navListener);
}
private BottomNavigationView.OnNavigationItemSelectedListener navListener =
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Fragment SelectedFragment=null;
FragmentManager fm=getSupportFragmentManager();
FragmentTransaction ft=fm.beginTransaction();
ft.commit();
switch (item.getItemId()) {
case R.id.navigation_home:
setTitle("Playing11");
HomeFragment fragment = new HomeFragment();
ft.replace(R.id.fragment_container, fragment);
return true;
case R.id.navigation_dashboard:
HomeFragment1 fragment1 = new HomeFragment1();
ft.replace(R.id.fragment_container, fragment1);
return true;
case R.id.navigation_notifications:
setTitle("Safe11");
HomeFragment2 fragment2 = new HomeFragment2();
ft.replace(R.id.fragment_container, fragment2);
return true;
case R.id.navigation_notification:
setTitle("More");
HomeFragment3 fragment3 = new HomeFragment3();
ft.replace(R.id.fragment_container, fragment3);
return true;
}
return false;
}
};
}
Try to change your code like this:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
switch (item.getItemId()) {
case R.id.menu_home:
HomeFragment homeFragment = new HomeFragment();
fragmentTransaction.replace(R.id.frameContentPlace, homeFragment, "HomeFragment").addToBackStack("HomeFragment");
break;
case R.id.menu_profile:
HomeFragment1 fragment1 = new HomeFragment1();
fragmentTransaction.replace(R.id.frameContentPlace, fragment1).addToBackStack("HomeFragment1");
break;
case R.id.menu_bookings:
HomeFragment2 fragment2 = new HomeFragment2();
fragmentTransaction.replace(R.id.frameContentPlace, fragment2).addToBackStack("HomeFragment2");
break;
}
fragmentTransaction.commit();
return true;
}
When you adding fragment use tag. So write
ft.replace(R.id.fragment_container, fragment, "MyFragment);
instead of
ft.replace(R.id.fragment_container, fragment);
And check if this fragment is visible for not loading this fragment again
switch (item.getItemId())
{
case R.id.navigation_home:
HomeFragment fragment = (HomeFragment)getFragmentManager().findFragmentByTag("MyFragment");
if (fragment != null && !fragment.isVisible())
{
setTitle("Playing11");
HomeFragment fragment = new HomeFragment();
ft.replace(R.id.fragment_container, fragment);
return true;
}
}
How can I use onBackPressed in BottonNavigationView to select an item? For example, if I press item 2 I go to fragment number 2, but when I push back, I go back to fragment number 1 and item 2 is still selected, item 1 is not selected which is the one corresponding to fragment 1 ...
This is my code
private BottomNavigationViewEx.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
= new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
switch (item.getItemId()) {
case R.id.mapa:
transaction.replace(R.id.content, new MapFragment());
getSupportFragmentManager().popBackStack();
transaction.commit();
return true;
case R.id.taxi:
transaction.replace(R.id.content, new TaxiFragment());
transaction.addToBackStack(null);
getSupportFragmentManager().popBackStack();
transaction.commit();
return true;
case R.id.help:
transaction.replace(R.id.content, new HelpFragment());
transaction.addToBackStack(null);
getSupportFragmentManager().popBackStack();
transaction.commit();
return true;
case R.id.go:
transaction.replace(R.id.content, new GoFragment());
transaction.addToBackStack(null);
getSupportFragmentManager().popBackStack();
transaction.commit();
return true;
}
return false;
}
};
}
UPDATE
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mapa);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.replace(R.id.content, new MapFragment()).commit();
BottomNavigationViewEx bottomNavigationViewEx = (BottomNavigationViewEx) findViewById(R.id.bottomViewBar);
bottomNavigationViewEx.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
BottomNavigationViewHelper.setupBottomNavigationView(bottomNavigationViewEx);
bottomNavigationViewEx.setSelectedItemId(R.id.mapa);
MenuItem item = bottomNavigationViewEx.getMenu().getItem(0);
if (!item.isChecked()) item.setChecked(true);
}
private BottomNavigationViewEx.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
= new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
switch (item.getItemId()) {
case R.id.mapa:
transaction.replace(R.id.content, new MapFragment());
getSupportFragmentManager().popBackStack();
transaction.commit();
return true;
case R.id.taxi:
transaction.replace(R.id.content, new TaxiFragment());
transaction.addToBackStack(null);
getSupportFragmentManager().popBackStack();
transaction.commit();
return true;
case R.id.help:
transaction.replace(R.id.content, new HelpFragment());
transaction.addToBackStack(null);
getSupportFragmentManager().popBackStack();
transaction.commit();
return true;
case R.id.go:
transaction.replace(R.id.content, new GoFragment());
transaction.addToBackStack(null);
getSupportFragmentManager().popBackStack();
transaction.commit();
return true;
}
return false;
}
};
#Override
public void onBackPressed () {
if (mCurrentItem > 0) {
mCurrentItem--;
showFragment (mCurrentItem);
} else {
super.onBackPressed();
}
}
private void showFragment(int currentItem) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
switch (currentItem) {
case 0:
transaction.replace(R.id.content, new MapFragment());
getSupportFragmentManager().popBackStack();
transaction.commit();
break;
case 1:
transaction.replace(R.id.content, new TaxiFragment());
getSupportFragmentManager().popBackStack();
transaction.commit();
break;
case 2:
transaction.replace(R.id.content, new HelpFragment());
getSupportFragmentManager().popBackStack();
transaction.commit();
break;
case 3:
transaction.replace(R.id.content, new GoFragment());
getSupportFragmentManager().popBackStack();
transaction.commit();
break;
}
}
}
I have this now, but I don't know if is correct
Keep a variable to denote which Fragment is your current. Inside onBackPressed, check what is the current Fragment, and decide where do you want to navigate to.
#Override
public void onBackPressed() {
if (mCurrentItem > 0) {
mCurrentItem--;
showFragment(mCurrentItem);
} else {
super.onBackPressed();
}
}
Your showFragment(mCurrentItem) can show different page based on the value, or however you'd like it to.
private void showFragment(int currentItem) {
switch (currentItem) {
case 0:
transaction.replace(R.id.content, new MapFragment());
getSupportFragmentManager().popBackStack();
transaction.commit();
break;
case 1:
...
}
}
Then inside your showFragment(currentItem) method, add this code to select the item on BottomNavigationView:
MenuItem item = mBottomNavigationView.getMenu().getItem(mCurrentItem);
if (!item.isChecked()) item.setChecked(true);
Solve my problem by adding this line inside the class of my corresponding fragment in the onCreateView method, so when pressing back the item is selected.
BottomNavigationViewEx navigation =
getActivity().findViewById(R.id.YourNavigationId);
Menu drawer_menu = navigation.getMenu();
MenuItem menuItem;
menuItem = drawer_menu.findItem(R.id.YourItemId);
if(!menuItem.isChecked())
{
menuItem.setChecked(true);
}
I am trying to create an app. I want to change navigation drawer icon to back Arrow in Action Bar and when i open a fragment and go back to main activity when i click on back arrow in fragment Using the following code-

Remove the below code :

getActionBar().setHomeButtonEnabled(true);
getActionBar().setDisplayHomeAsUpEnabled(true);
// Setting item click listener for the listview mDrawerList
mDrawerList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent,

displayView(position);
// Updating the action bar title
String[] menu = getResources().getStringArray(R.array.menu);

Use the following after mDrawerLayout.setDrawerListener(mDrawerToggle);
I create Navigation Drawer using fragments and Action Bar Tabs using Fragment. But when I compile it, I am having issue. My app unfortunately stop working. My code wasn't error, and I am so confused whats wrong?
