I am trying to combine TabLayout and BottomNavigationView in one TabsActivity.java file. TabLayout works fine but facing problem with BottomNavigationView. It doesn't display its fragment pages content on ViewPager ( #+id/container ) but it hides and shows TabLayout which means it's getting through switch (item.getItemId()) { cases.
It loads first page during app start but once I click on bottom tabs all I see is white pages on every tab. Any idea how to fix this problem?
java
public class TabActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tab);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
final SectionsPagerAdapter mSectionsPagerAdapter;
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
final ViewPager mViewPager;
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
final TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
BottomNavigationView bottomNavigationView = (BottomNavigationView)
findViewById(R.id.navigation);
bottomNavigationView.setOnNavigationItemSelectedListener
(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Fragment selectedFragment = null;
switch (item.getItemId()) {
case R.id.action_item1:
selectedFragment = HomeTab.newInstance();
tabLayout.setVisibility(View.VISIBLE);
break;
case R.id.action_item2:
selectedFragment = StatusTab.newInstance();
tabLayout.setVisibility(View.GONE);
break;
}
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.container, selectedFragment);
transaction.commit();
return true;
}
});
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.container, HomeTab.newInstance());
transaction.commit();
}
public void do_refresh(View v){
//try refresh onclick
}
private class SectionsPagerAdapter extends FragmentPagerAdapter {
private SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0:
return new HomeTab();
case 1:
return new SecondTab();
case 2:
return new ThirdTab();
default:
return null;
}
}
#Override
public int getCount() {
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Home";
case 1:
return "Second";
case 2:
return "Third";
}
return null;
}

it should be your frame layout to be replaced with selected fragment, not view pager

I'm trying a fragment navigation drawer, Everything works out fine, but the issue is that I don't want to have a fragment fab on my second fragment.
I really appreciate the help given. Thank you!

paste this code before break statement in onNavigationItemSelectedMethod.
you have to attach the fragment to activity.
Hi I have a small problem with the tab layout. After I have implemented tab layout and put the recycle view in I have the problem that after I scroll the list the toolbar seem to blend with the title. Am I making the mistake in the code tab activity or its some other issue.

I have ONE activity that calls a FragmentParent. This contains a viewpager. The viewpager has 2 tabs. In each tab there is a fragment. In the first tab (TAB-A) there is a fragment that contains a Recyclerview. When I click over an item the app opens new fragment, but when I go back ALL the fragments inside the viewpager get empty.
I am using Fragments and support library v-13, I already tried with v-4 but I had the same issue.

// getItem is called to instantiate the fragment for the given page.

switch (position) {

#Override

return null;
}
}
I am using FragmentTransaction to replace Fragments...
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.fragment_container,settingFragment);
ft.addToBackStack(null);
ft.commit();
If you guys can help me, I will really appreciate
Thanks
This is what I want to:
change FragmentA layout
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorGrayLight"
android:orientation="vertical"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<LinearLayout
android:id="#+id/container_recycler"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1">
<android.support.v7.widget.RecyclerView
android:id="#+id/video_recycler_view"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
</FrameLayout>
Now when you replace fragment with this
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.fragment_container,settingFragment);
ft.addToBackStack(null);
ft.commit();
it will take R.id.fragment_container from FragmentA
I finally resolved using getChildFragments:
I used getChildFragmentManager instead of getFragmentManager. I passed to the constructor of the PageAdapter
SectionsPageAdapter mSectionsPagerAdapter = new SectionsPageAdapter(getChildFragmentManager());
In the view holder of the RecyclerView I created an Interface to communicate Nested Fragments with the Activity(main container). Using this way I could replace Fragments in the R.id.fragment_container
I found the solution in this link:
Adding child Fragment to Parent Fragment withing a ViewPager in Android
I have successfully used TabLayout with AppCompatActivity with a CoordinatorLayout that looks close to this snippet:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:fab="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="snap"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabMode="fixed" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content" />
</android.support.design.widget.CoordinatorLayout>
Now I have implemented a NavigationDrawer and I am struggling to implement tabs within one of the Fragments being shown inside my AppCompatActivity. I want to be able to switch with TabLayout between few child Fragments inside of this Fragment.
How do I access TabLayout from one of my Fragments?
How do I set PagerAdapter for each of the Fragments correctly?
Where do I call addOnPageChangeListener?
How do I hide TabLayout when one of my Fragments does not need to
display tabs?
1. Switching between first-level Fragments
Suppose layout content.xml stands for:
<FrameLayout 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:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".ui.MyActivity"
tools:showIn="#layout/my_activity" />
Then, to be able to switch between the Fragments, implement this function:
private void makeTransition(int fragmentId) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
switch (fragmentId) {
// Fragment with tabs
case FRAGMENT_TABS:
fragmentTransaction.replace(R.id.fragment_container, new TabsFragment());
// This shows TabLayout
findViewById(R.id.tabs).setVisibility(View.VISIBLE);
getSupportActionBar().setTitle(R.string.fragment_tabs_title);
break;
// Fragment with no tabs
case FRAGMENT_NO_TABS:
fragmentTransaction.replace(R.id.fragment_container, new NoTabsFragment());
// This hides TabLayout
findViewById(R.id.tabs).setVisibility(View.GONE);
getSupportActionBar().setTitle(R.string.fragment_no_tabs_title);
break;
default:
throw new RuntimeException("No fragment with ID " + fragmentId + " found");
}
fragmentTransaction.commit();
}
2. Accessing and setting up TabLayout from first-level Fragment
In TabsFragment class, add a private class TabAdapter:
private class TabAdapter extends FragmentPagerAdapter {
public TabAdapter(FragmentManager fm) {
super(fm);
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "TAB1";
case 1:
return "TAB2";
// ...
}
return null;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return Tab1Fragment.getInstance();
case 1:
return Tab2Fragment.getInstance();
// ...
}
return null;
}
#Override
public int getCount() {
return 2;
}
}
Also, optionally, implement a ViewPager.OnPageChangeListener:
private class FragmentPageChangeListener implements ViewPager.OnPageChangeListener {
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
Log.d(getClass().getName(), "onPageScrolled");
}
#Override
public void onPageSelected(int position) {
Log.d(getClass().getName(), "onPageSelected");
}
#Override
public void onPageScrollStateChanged(int state) {
Log.d(getClass().getName(), "onPageScrollStateChanged");
}
}
Suppose your layout for fragment with tabs is like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true" />
</RelativeLayout>
Override onCreateView to look like this:
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.viewpager_fragment, null);
fragmentPagerAdapter = new TabAdapter(getChildFragmentManager());
fragmentPageChangeListener = new FragmentPageChangeListener();
ViewPager pager = (ViewPager) view.findViewById(R.id.viewpager);
pager.setAdapter(fragmentPagerAdapter);
pager.addOnPageChangeListener(fragmentPageChangeListener);
TabLayout tabLayout = (TabLayout) MyAcvtivity.getInstance().findViewById(R.id.tabs);
tabLayout.setupWithViewPager(pager);
return view;
}
NB:
Use getChildFragmentManager() and not getFragmentManager() in first-level Fragments when instantiating a ViewPager.
I am trying to implement both tabs and navigation drawer.
I have already successfully implemented tabs, and I started to insert navigation drawer, now just in my activity_main.xml layout.
I don't know how to implement this in my main activity, since all tutorials I have found don't use the same structure I use for my tabs.
Ideally, I want that on a click to the last tab, the navigation drawer opens from right, like that I could mask ActionBar (like Airbnb did)
I think it could be possible either with moving my tabs on action bar, or making a tab icon click to open navigation drawer (simpler I think.
If it is not possible, keep my sliding tabs and their "links" just bellow action bar.
How do you think I can activate/display and populate my navigation drawer, without disturbing my tabs ?
