i use Bottom Navigation View and on a fragment its not work fine the problem is there is no transition its only display the first selected
navigationView.setSelectedItemId(R.id.message_menu_Friend);
my code
public class MessageFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView =inflater.inflate(R.layout.fragment_message, container, false);
BottomNavigationView navigationView = rootView.findViewById(R.id.top_navigation_bar);
navigationView.setOnNavigationItemSelectedListener(topNav);
navigationView.setSelectedItemId(R.id.message_menu_Friend);
getChildFragmentManager().beginTransaction().replace(R.id.hostFragment_M,new FriendFragment()).commit();
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_message, container, false);
}
private BottomNavigationView.OnNavigationItemSelectedListener topNav = new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Fragment selectedItem = null;
switch (item.getItemId()) {
case R.id.message_menu_message:
selectedItem = new MessagesFragment();
break;
case R.id.message_menu_Friend:
selectedItem = new FriendFragment();
break;
}
assert selectedItem != null;
getChildFragmentManager().beginTransaction().replace(R.id.hostFragment_M,selectedItem).commit();
return true ;
}
};}

how can i make it display the fragment when i click on the bottom navigation
Remove the line navigationView.setSelectedItemId(R.id.message_menu_Friend);, and also change getChildFragmentManager() to getSupportFragmentManager(). Also, in the onCreate method, just return rootView instead of inflating again.

Like a lot of other people on the stackoverflow, for example:
https://ru.stackoverflow.com/questions/571704/%D0%A0%D0%B0%D0%B7%D0%BD%D1%8B%D0%B9-%D0%BA%D0%BE%D0%BD%D1%82%D0%B5%D0%BD%D1%82-%D0%BD%D0%B0-%D1%81%D1%82%D1%80%D0%B0%D0%BD%D0%B8%D1%86%D0%B0%D1%85-viewpager
I'm trying to create ViewPager with different layouts, but with:
https://github.com/ogaclejapan/SmartTabLayout
Expectation: beautiful ViewPager with 3 tabs, which can switch different layouts/fragments by clicking on the buttons or by swipe.
Reality: beautiful ViewPager with 3 tabs, which are doing nothing.
Looking for your help, thanks.
What I have done in MainActivity class:
public class MainActivity extends AppCompatActivity
{
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().setElevation(0); //toolbar shadow
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
ViewGroup tab = findViewById(R.id.linear_test);
tab.addView(LayoutInflater.from(this).inflate(R.layout.activity_main, tab, false));
ViewPager viewPager = findViewById(R.id.viewpager);
SmartTabLayout viewPagerTab = findViewById(R.id.viewpagertab);
setup(viewPagerTab);
FragmentPagerItems pages = new FragmentPagerItems(this);
pages.add(FragmentPagerItem.of("Вкладка 1", DemoFragment.class));
pages.add(FragmentPagerItem.of("Вкладка 2", DemoFragment.class));
pages.add(FragmentPagerItem.of("Вкладка 3", DemoFragment.class));
FragmentPagerItemAdapter adapter = new FragmentPagerItemAdapter(
getSupportFragmentManager(), pages);
viewPager.setAdapter(adapter);
viewPagerTab.setViewPager(viewPager);
}
public void setup(final SmartTabLayout layout) {
//Do nothing.
}
}
What I have done in my DemoFragment:
public class DemoFragment extends Fragment {
static final String ARGUMENT_PAGE_NUMBER = "arg_page_number";
private int page;
static DemoFragment newInstance(int page) {
DemoFragment pageFragment = new DemoFragment();
Bundle arguments = new Bundle();
arguments.putInt(ARGUMENT_PAGE_NUMBER, page);
pageFragment.setArguments(arguments);
return pageFragment;
}
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
// View view = inflater.inflate(R.layout.activity_main, container, false);
page = getArguments().getInt("someInt", 0);
return inflater.inflate(R.layout.activity_main, container, false);
// return view;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
int position = FragmentPagerItem.getPosition(getArguments());
getItem(position);
}
public Fragment getItem(int position) {
switch (position) {
case 0: // Fragment # 0 - This will show FirstFragment
return DemoFragment.newInstance(1);
case 1: // Fragment # 0 - This will show FirstFragment different title
return DemoFragment.newInstance(2);
case 2: // Fragment # 1 - This will show SecondFragment
return DemoFragment.newInstance(3);
default:
return null;
}
}
}

I have a simple main java "GameMode" that will show 3 tabs fragments, one of them is "HkmjSetting" (will be shown below), now when I run the app, it works just fine, but any click on the button has no response. No red lines were found in android studio..
GameMode java:
public class GameMode extends AppCompatActivity {
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game_mode);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_game_mode, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public static class PlaceholderFragment extends Fragment {
private static final String ARG_SECTION_NUMBER = "section_number";
public PlaceholderFragment() {
}
public static PlaceholderFragment newInstance(int sectionNumber) {
PlaceholderFragment fragment = new PlaceholderFragment();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (getArguments().getInt(ARG_SECTION_NUMBER)==1) {
View rootView = inflater.inflate(R.layout.fragment_hkmj_setting, container, false);
return rootView;
} else if (getArguments().getInt(ARG_SECTION_NUMBER)==2) {
View rootView = inflater.inflate(R.layout.fragment_quickmj_setting, container, false);
return rootView;
} else {
View rootView = inflater.inflate(R.layout.fragment_hkmj_setting, container, false);
// TextView textView = (TextView) rootView.findViewById(R.id.section_label);
//textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER)));
return rootView;
}
}
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
return PlaceholderFragment.newInstance(position + 1);
}
#Override
public int getCount() {
// Show 3 total pages.
return 3;
}
}
}
HkmjSetting java:
public class HkmjSetting extends Fragment {
Button btn_next;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_hkmj_setting, container, false);
btn_next = (Button) view.findViewById(R.id.btn_next);
btn_next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
/* Intent intent = new Intent(v.getContext(), MainActivity.class);
startActivity(intent);*/
Toast.makeText(getActivity(), "TESTING", Toast.LENGTH_SHORT).show();
}
});
return view;
}
}
Run results no error, but nothing happen when clicked on the "btn_next", this may be a silly question to many of you, but please help...Thanks!

Change the getItem() method body to if (position == 2) { return new HkmjSetting(); } else { return PlaceholderFragment.newInstance(position + 1); }
as suggested by #Mike M.
Thanks! it works!
I have a parent layout that is used to inflate various fragments. On one such fragment layout I need to access the view elements inside the fragment class.
I'm using below code to get a reference for a text view inside the fragments layout.
CreateTaskFragment.java
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
View view = getView();
endDateView = (TextView)view.findViewById(R.id.estimated_end_input);
endDateView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.i("Date","I'm clicked");
}
});
}
The endDateView is returning null.

How can I get the reference to the view elements of CreateTaskFragment?
Copy below method in your fragment and remove your onActivityCreated method from fragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_create_task, container, false);
TextView endDateView = (TextView)rootView .findViewById(R.id.estimated_end_input);
endDateView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.i("Date","I'm clicked");
}
});
return rootView;
}
I am trying to add a fragment from an activity using the add(R.id.containerId, fragment);. However the log gives the java.lang.IllegalArgumentException: No view found for id error.
The fragment layout contains an id in the root element. I know that placing the container id in a child element is supposed to fix things, but this has made no difference for me.
Here is the root element in the fragment layout xml file:
<LinearLayout

Here is the onCreate() method in my activity:
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.add(R.id.fragment_container, fragment);
currentFragment = R.id.fragment_container;
transaction.commit();
Here is the onCreateView() method in the fragment:
return inflater.inflate(R.layout.fragment, container, false);
Here is the entire activity code (the naming and ids are different because I changed them in the snippets above, imports statements are also missing for brevity):
public class MainActivity extends AppCompatActivity {
private int currentFragmentId;

Here is the main parts of the logcat stacktrace (the naming and ids are different because I changed them in the snippets above, imports statements are also missing for brevity):
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.tomfinet.magpie/com.tomfinet.magpie.view.MainActivity}: java.lang.IllegalArgumentException: No view found for id 0x7f0c0076 (com.tomfinet.magpie:id/fragment_feed_container) for fragment FeedFragment{c9899d7 #0 id=0x7f0c0076}
Caused by: java.lang.IllegalArgumentException: No view found for id 0x7f0c0076 (com.tomfinet.magpie:id/fragment_feed_container) for fragment FeedFragment{c9899d7 #0 id=0x7f0c0076}
Stuff that I have checked:
Fragment layout is correct in the onCreateView() method in the fragment.
Fragment layout container id in child of the fragment xml file.
How do I fix this error?
Thank you.
so I know there are a few topics around here that ask about this but none seemed to be the cause of my issue. I have an ActionBarActivity that is going to be switching between a few different fragments, but I'm having a problem getting one of the fragments to show up. The activity does show a fragment when it is first loaded and does that fine. Here is the code that is setting up the initial fragment with the method to switch between fragments that I'm using.
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_container);
final ActionBar actionBar = getSupportActionBar();
actionBar.setTitle("");
if (savedInstanceState == null) navigateTo(START_SCREEN);
}
public void navigateTo(int sectionNumber, Serializable objectParam) {
Fragment fragment = null;
switch (sectionNumber) {
case START_SCREEN:
fragment = createStartScreenFragment(); //returns an instance of the class for this fragment
break;
case SCREEN_TWO:
fragment = createSecondScreenFragment(); //returns an instance of the class for this fragment
break;
}
if (fragment == null) return;
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction trans = fm.beginTransaction();
trans.add(R.id.activity_container, fragment, fragment.getTag());
trans.commit();
trans.show(fragment);
}
activity_containers.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:id="#+id/activity_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
The first fragment that loads successfuly
<GridLayout
android:id="#+id/fragment_start_screen"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.android.Activity">
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
/>
...
</GridLayout>
And here is the fragment xml that isn't showing up
<TextView android:id="#+id/section_label" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fadingEdge="vertical"
android:cacheColorHint="#00000000"
android:fastScrollEnabled="true"
android:padding="2dp">
</ListView>
And here is the misbehaving fragments relevant code:
public class SecondFragment extends Fragment {
public final static int SECTION_NUMBER = 1;
private String mTag = "TAG";
private ParentActivity parentActivity;
public SecondFragment() {
}
public static fragment newInstance() {
SecondFragment fragment = new SecondFragment();
Bundle args = new Bundle();
fragment.setArguments(args);
return fragment;
}
#Override
public void onAttach(final Activity activity) {
super.onAttach(activity);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
parentActivity = (ParentActivity) getActivity();
View rootView = inflater.inflate(R.layout.fragment_second_fragment, container, false);
ListView list = (ListView) rootView.findViewById(R.id.list);
return super.onCreateView(inflater, container, savedInstanceState);
}
}
The biggest problem I'm having here is that there is no error message shown. The text view in the first fragment is supposed to trigger the second fragment to show up on the screen. This used to work when I had that fragment as a DialogFragment and just called .show() on an instance of it. I need it to be a regular fragment now and it doesn't show up. There's no error message that I can see, though debugging it does show it running through all of my code successfully and it looks like its properly inflating the view.
So what could I be missing here that is preventing the fragment from displaying?
Your layout
<TextView android:id="#+id/section_label" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fadingEdge="vertical"
android:cacheColorHint="#00000000"
android:fastScrollEnabled="true"
android:padding="2dp">
</ListView>
Should be within a ViewGroup
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView android:id="#+id/section_label" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fadingEdge="vertical"
android:cacheColorHint="#00000000"
android:fastScrollEnabled="true"
android:padding="2dp">
</ListView>
</LinearLayout>
And you should return rootView in onCreateView().
Also, you might need to use replace method of Fragment Manager to replace one fragment with another, instead of add.
