I have a nav drawer which in its first fragment i have a news page where the user clicks a button to see the whole news, and at that moment it enters another fragment.
I want to know how I implement an arrow to return to the previous fragment instead of the icon that opens the Navigation Drawer.
I've never worked with this before, I have no idea.
This is my Toolbar in MainActivity
appBarLayout = (AppBarLayout) findViewById(R.id.appBarLayout);
toolbar = (Toolbar) findViewById(R.id.toolbar);
//toolbar title
toolbar.setTitle(null);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
// Toolbar logo
logoToolbar = (ImageView) findViewById(R.id.logoToolbar);
logoToolbar.setImageResource(R.drawable.newstoolbar);
When the user click in "Read More" in the MainFragment
newsMore.get(0).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.fade_in, R.anim.fade_out);
newsFrag1 newsFragment1 = new newsFrag1();
ft.replace(R.id.fragment_container, newsFragment1);
ft.commit();
}
});
And then it goes to newsFrag1, which I want to have the back arrow

Fragments don't normally intercept back/up presses. That is something that's normally done at the activity level. The reasoning behind that is because you can have multiple fragments on screen at the same time... so which one handles the back press first?
To handle it in your activity, consider keeping track of your before and after state. Let's use the fragment count as an example state:
#Override
public void onBackPressed() {
// for every back press, if there is a fragment to remove, then remove it first
if (getFragmentManager().getBackStackEntryCount() > 0) {
getFragmentManager().popBackStack();
return;
}
super.onBackPressed();
}
You also need to make sure you add your original fragment transaction to the backstack:
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.fade_in, R.anim.fade_out);
newsFrag1 newsFragment1 = new newsFrag1();
ft.replace(R.id.fragment_container, newsFragment1);
ft.addToBackStack();
ft.commit();
Edit: I think from your xml what you're asking for is UP navigation, not BACK navigation. If that is the case, then you still need to leverage the backstack but all the work needs to be done by the parent activity (because the activity owns the toolbar)
getSupportFragmentManager()
.addOnBackStackChangedListener(new OnBackStackChangedListener(){
#Override
public void onBackStackChanged() {
updateToolbarUp();
}
});
public void updateToolbarUp(){
boolean showUp = getSupportFragmentManager().getBackStackEntryCount() > 0;
getSupportActionBar().setDisplayHomeAsUpEnabled(showUp);
}
Then override the up press to simply pop the backstack:
#Override
public boolean onSupportNavigateUp() {
getSupportFragmentManager().popBackStack();
return true;
}

I am currently trying to create an app having a splash screen, a login screen and a register screen.
The only way to achieve exactly what I need is through fragments. Though when I try to transition from the splash screen to the login fragment the text view which was part of the splash screen remains. The same happens after transitioning from the login fragment to the register fragment as well as from the register fragment back to the login fragment. It is important to note that there is no issue during transitioning between login and register or between register and login - except the fact that the edit text stays there.
My MainActivity.java
public class StartActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
}
#Override
public void onBackPressed(){
Toast.makeText(getApplicationContext(), "Back button is disabled", Toast.LENGTH_SHORT).show();
}
}
My layout for MainActivity
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".StartActivity"
android:background="#mipmap/background">
<fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/viewpagerstart"
android:layout_centerInParent="true"
android:name="com.example.distributedsystemsui.SplashFragment">
</fragment>
</RelativeLayout>
The SplashScreen.java
public class SplashFragment extends Fragment {
LinearLayout linearLayout;
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_splash, container, false);
linearLayout = (LinearLayout) view.findViewById(R.id.f_linearsplash);
Animation animation_fadein = AnimationUtils.loadAnimation((StartActivity)getActivity(), R.anim.fade_in);
linearLayout.startAnimation(animation_fadein);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_enter_left, R.anim.slide_exit_left,
R.anim.slide_enter_right, R.anim.slide_exit_right);
LoginFragment loginFragment = LoginFragment.newInstance();
ft.replace(R.id.viewpagerstart, loginFragment);
ft.commit();
}
}, 3000);
return view;
}
}
And the layout for the SplashScreen fragment.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

android:text="#string/app_name"
android:layout_gravity="center_horizontal"
android:layout_marginTop="100dp"
android:background="#FFFFFF"/>
</LinearLayout>
</FrameLayout>
All my search led back to nothing.
I can only assume that either the below contained in the MainActivity.xml creates a confusion (which I tried to change but no luck):
android:name="com.example.distributedsystemsui.SplashFragment"
or that I am doing a mistake in the SplashScreen.java that I cannot locate, even though I tried for more than 5 hours to make it work.
The problem is that you cannot replace fragments added via the <fragment> tag.
Instead, you should either:
1) Switch to FragmentContainerView, which was added in Fragment 1.2.0. It does not suffer from the same issue as the <fragment> tag and lets you do replace operations without issues:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".StartActivity"
android:background="#mipmap/background">
<androidx.fragment.app.FragmentContainerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/viewpagerstart"
android:layout_centerInParent="true"
android:name="com.example.distributedsystemsui.SplashFragment">
</androidx.fragment.app.FragmentContainerView>
</RelativeLayout>
2) Use a FrameLayout in your layout and manually add the SplashFragment in your activity (this is essentially what FragmentContainerView does for you):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".StartActivity"
android:background="#mipmap/background">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/viewpagerstart"
android:layout_centerInParent="true">
</FrameLayout>
</RelativeLayout>
which means you need to add the SplashFragment manually:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.viewpagerstart, new SplashFragment())
.commit()
}
}
I think it is better to do the fragment transactions from your activity instead of doing it from your fragment. You might consider having functions in your MainActivity as follows.
public class StartActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
}
public void goToLoginFragment() {
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_enter_left, R.anim.slide_exit_left,
R.anim.slide_enter_right, R.anim.slide_exit_right);
LoginFragment loginFragment = LoginFragment.newInstance();
ft.replace(R.id.viewpagerstart, loginFragment);
ft.commit();
}
public void goToRegisterFragment() {
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_enter_left, R.anim.slide_exit_left,
R.anim.slide_enter_right, R.anim.slide_exit_right);
LoginFragment registerFragment = RegisterFragment.newInstance();
ft.replace(R.id.viewpagerstart, registerFragment);
ft.commit();
}
#Override
public void onBackPressed(){
Toast.makeText(getApplicationContext(), "Back button is disabled", Toast.LENGTH_SHORT).show();
}
}
And then from your SplashFragment call the function that is defined in your activity.
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
((MainActivity) getActivity()).goToLoginFragment();
}
}, 3000);
I hope that solves the problem.
This one activity but i try to close the bottom navigation when the user selected one of the side menu fragment. Example when i click my account the bottom not hide.
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId()){
case R.id.nav_account:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
new AccountFragment()).commit();
break;
case R.id.nav_support:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
new SupportFragment()).commit();
break;
case R.id.nav_aboutus:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
new AboutusFragment()).commit();
break;
case R.id.nav_logout:
firebaseAuth.signOut();
startActivity(new Intent(getApplicationContext(),Signin.class));
break;
}
mDrawerlayout.closeDrawer(GravityCompat.START);
return true;
}
I hope that will simple code or maybe add another activity?
This my layout

Maybe put some code in navigation or bottom navigation
As your container and BottomNavigation in same activity layout and you are using your container for fragment.
Create one interface
public interface IBottomBarListener{
public void showBottomBar();
public void hideBottomBar()
}
Implement this interface in your activity and override these two methods.
public void showBottomBar(){
// make your bottom bar visibility visible
}
public void hideBottomBar(){
// make your bottom bar visibility gone
}
Now in your fragment declare global variable
public IBottomBarListener listener;
Now in onAttach() method , init your listener
listener = (IBottomBarListener)context
now in onCreateView(), call
listener.hideBottomBar() // this will hide your bottombar
also in onDetach() method, if you want to again make visible your bottombar,
onDetach(){
listener.showBottomBar() // this will show your bottombar
}
This is basically showing/hiding your bottombar from your fragment. So do same in all fragment from where you want to perform this action.
I'm trying to implement a bottom nav bar that changes fragments when the nav items are clicked. However, when I click on the nav bar items, the fragments don't change. Using log.d, I noticed onNavigationItemSelected is not being called. How do I fix this?
To note, the startFeedFragment, startScheduleFragment, & startSettingsFragmentare implemented the same way and they work for the buttons in the toolbar. I also referenced this tutorial and this question for help.
MainActivity.java
public class MainActivity extends AppCompatActivity implements BottomNavigationView.OnNavigationItemSelectedListener {
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
setUpRecycler();
startFeedFragment();
BottomNavigationView bottomNavBar = (BottomNavigationView) findViewById(R.id.navigation);
bottomNavBar.bringToFront();
bottomNavBar.setOnNavigationItemSelectedListener(this);
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Log.d("NAV BAR", "onNavigationItemSelected hit");
switch (item.getItemId()) {
case R.id.feedMenu:
startFeedFragment();
Log.d("NAV BAR", "feed");
break;
case R.id.myScheduleMenu:
startScheduleFragment();
Log.d("NAV BAR", "schedule");
break;
case R.id.settingsMenu:
startSettingsFragment();
Log.d("NAV BAR", "settings lol");
break;
default:
Log.d("NAV BAR", "false");
return false;
}
return true;
}
/**
* Switches out the fragment for {#link FeedFragment} and sets an appropriate title. startScheduleFragmens & startSettingsFragment are implemented the same way
*/
private void startFeedFragment()
{
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.fragmentContainer, new FeedFragment());
transaction.commit();
getSupportActionBar().setTitle(R.string.title_fragment_feed);
}
}

Solved! It was because I had set the buttons in the menu to android:enabled="false". That meant they couldn't be pressed, which is why onNavigationItemSelected wasn't being called. I set all buttons to android:enabled="true" to fix this.
Correct code for bottom_nav.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/bottom_nav_my_schedule"
android:title="#string/menu_my_schedule"
android:icon="#drawable/ic_event_available_white_24dp"
android:enabled="true"/> <!--make sure enabled is set to true!-->
<item android:id="#+id/bottom_nav_feed"
android:title="#string/menu_feed"
android:icon="#drawable/ic_view_list_white_24dp"
android:enabled="true" /> <!--make sure enabled is set to true!-->
<item android:id="#+id/bottom_nav_settings"

android:enabled="true"/> <!--make sure enabled is set to true!-->
</menu>
As for me the problem was when my activity main layout was LinearLayout, so I've solved it by changing it to RelativeLayout, I have absolutely no thoughts why it's working, because RelativeLayout layouts reply only for elements location, not its view or something else, but it's working.
<RelativeLayout

Ok, say I have 1 Activity called MainActivity and 2 layouts linked to this actvity. In layout 1 i have a button which when clicked opens a webview in layout 2. How can I make it so when i press backbutton it goes back to layout 1 and doesnt exit the whole app.
Edit: fixed this by just creating another class and linking it to one of the layouts.
You have to override onBackPressed() in your activity and handle the logic there.
#Override
public void onBackPressed(){
if(/*layout2 visible*/){
// code here to go back to layout 1
}else{
super.onBackPressed();
}
}
I use this code using onBackPressed()
1- activity_main.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/go_to_second_layout"
android:text="Go to second layout"
android:onClick="onClick"/>
2- second_layout.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/second_layout">
3- MainActivity.java
public void onClick(View v){
switch(v.getId){
case R.id.go_to_second_layout:{
setContentView(R.layout.second_layout);
((LinearLayout)findViewById(R.id.second_layout)).setVisibility(View.VISIBLE);
break;}}}
#Override
public void onBackPressed() {
if (((LinearLayout)findViewById(R.id.second_layout)).VISIBLE==View.VISIBLE){
setContentView(R.layout.activity_main);
((LinearLayout)findViewById(R.id.second_layout)).setVisibility(View.GONE);
}
else {
super.onBackPressed();}
}
I'm using a DrawerLayout for the navigation of my app:
Taking this menu for the example:
I'd like the Home button to launch the HomeActivity and so on. But clearing the activity stack, that is: If I press People, then Photos, then Locations and then the back button, the app should close. I'm trying intent flags when launching the activities but I always get the same behaviour: People->Photos->Location->Back goes to Photos instead closing the app
How can I achieve that?
As per you said that "If I press People, then Photos, then Locations and then the back button, the app should close".
For achieve that you should user Fragment for Home,People,Location and Photos etc.
and when you press back button of Device you can clear Fragment back stack and finish activity.
I think this code may help you. When you press Back button of a device it will close the application.
In MainActivity.java,
public void SelectItem(int possition)
{
//Using Fragment here
Fragment fragment = null;
Bundle args = new Bundle();
switch (possition)
{
//Can use Fragment for Home,People,Location and Photos etc. and when you press back button of Device you can clear Fragment back stack and finish activity.
case 0:
fragment=new FragmentNewsFeed();
break;
case 1:
fragment = new FragmentMessages();
break;
default:
break;
}
fragment.setArguments(args);
FragmentManager frgManager = getFragmentManager();
frgManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
listView_drawer.setItemChecked(possition, true);
setTitle(dataList.get(possition).getItemName());
drawerLayout.closeDrawer(listView_drawer);
}
In FragmentNewsFeed class,
public class FragmentNewsFeed extends Fragment
{
public FragmentNewsFeed()
{
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.fragment_news_feeds, container,false);
return view;
}
}
Whereas you can find content frame in a layout/activity_main.xml,
<android.support.v4.widget.DrawerLayout
