I'm getting the same cardview images on my three tab layouts

I'm trying to create a cardview album recycler view and as I was finishing up my code I found out that my program is displaying the same cardview for all three tab layouts. I want to display different cardview album for different tab layouts.Any help please!! Here is my program output.

Showing different xmls by tabView

I've created a tab view by Android Studio, this is the default code for MainActivity.java:
public class MainActivity extends AppCompatActivity {
/**
* The {#link android.support.v4.view.PagerAdapter} that will provide
* fragments for each of the sections. We use a
* {#link FragmentPagerAdapter} derivative, which will keep every
* loaded fragment in memory. If this becomes too memory intensive, it
* may be best to switch to a
* {#link android.support.v4.app.FragmentStatePagerAdapter}.
*/
private SectionsPagerAdapter mSectionsPagerAdapter;
/**
* The {#link ViewPager} that will host the section contents.
*/
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**
* A placeholder fragment containing a simple view.
*/
public static class PlaceholderFragment extends Fragment {
/**
* The fragment argument representing the section number for this
* fragment.
*/
private static final String ARG_SECTION_NUMBER = "section_number";
public PlaceholderFragment() {
}
/**
* Returns a new instance of this fragment for the given section
* number.
*/
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) {
View rootView = inflater.inflate(R.layout.fragment_main, 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;
}
}
/**
* A {#link FragmentPagerAdapter} that returns a fragment corresponding to
* one of the sections/tabs/pages.
*/
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
// getItem is called to instantiate the fragment for the given page.
// Return a PlaceholderFragment (defined as a static inner class below).
return PlaceholderFragment.newInstance(position + 1);
}
#Override
public int getCount() {
// Show 3 total pages.
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "SECTION 1";
case 1:
return "SECTION 2";
case 2:
return "SECTION 3";
}
return null;
}
}
so I have three xmls:
one.xml
two.xml
fragment_main.xml
I want to change the layout of each tab to an unique xml that I mentioned.
I tried this way:
Added this to my MainActivity.java:
public class FrChange extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.one, container, false);
return rootView;
}
}
and then I changed this:
View rootView = inflater.inflate(R.layout.fragment_main, 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;
to this:
return new FrChange();
But it throws me bunch of errors.
What should I do?

My problem was with the adapter.

Implementing sliding tabs in drawer fragment

Just need a workaround!
I had already implemented drawer, now need to place sliding tabs in one of those fragments.
Fragment Class:
import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentTwo extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_two, container, false);
}
}
Method i am using needs to extend the same ‘FragmentTwo’ class to ‘ActionBarActivity’. Here is the code:
public class FragmentTwo extends ActionBarActivity {
// Declaring Your View and Variables
Toolbar toolbar;
ViewPager pager;
ViewPagerAdapter adapter;
SlidingTabLayout tabs;
CharSequence Titles[] = {“Test1”, “Test2”, “Test3”};
int Numboftabs = 3;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Creating The Toolbar and setting it as the Toolbar for the activity
toolbar = (Toolbar) findViewById(R.id.tool_bar);
setSupportActionBar(toolbar);
// Creating The ViewPagerAdapter and Passing Fragment Manager, Titles fot the Tabs and Number Of Tabs.
adapter = new ViewPagerAdapter(getSupportFragmentManager(), Titles, Numboftabs);
// Assigning ViewPager View and setting the adapter
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(adapter);
// Assiging the Sliding Tab Layout View
tabs = (SlidingTabLayout) findViewById(R.id.tabs);
tabs.setDistributeEvenly(true); // To make the Tabs Fixed set this true, This makes the tabs Space Evenly in Available width
// Setting Custom Color for the Scroll bar indicator of the Tab View
tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
#Override
public int getIndicatorColor(int position) {
return getResources().getColor(R.color.tabsScrollColor);
}
});
// Setting the ViewPager For the SlidingTabsLayout
tabs.setViewPager(pager);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
I know a class cannot be extended to more than one class in java. But is there some other way to get this done?

Placing a ViewPager inside a Fragment that is created by a NavigationDrawer is the same way as placing a ViewPager inside a simple Fragment created inside an Activity.
Inside of class Fragment two implement the ViewPager like that:
public class FragmentTwo extends Fragment {
private ViewPager pager;
private ViewPagerAdapter adapter;
private SlidingTabLayout tabs;
private static CharSequence titles[];
private final int numOfTabs = 3;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_slidetab, container, false);
// set your titles here
adapter = new ViewPagerAdapter(getActivity().getSupportFragmentManager(),titles, numOfTabs);
pager = (ViewPager) rootView.findViewById(R.id.pager);
pager.setAdapter(adapter);
tabs = (SlidingTabLayout) rootView.findViewById(R.id.tabs);
tabs.setDistributeEvenly(true); // To make the Tabs Fixed set this true, This makes the tabs Space Evenly in Available width
tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
#Override
public int getIndicatorColor(int position) {
return getResources().getColor(R.color.tabsScrollColor);
}
});
tabs.setViewPager(pager);
//mSwipeRefreshLayout = (SwipeRefreshLayout) layout.findViewById(R.id.swipeRefreshLayout);
return rootView;
}
}
For the ViewPager you need an Adapter class:
public class ViewPagerAdapter extends FragmentStatePagerAdapter {
CharSequence Titles[];
int NumbOfTabs;
public ViewPagerAdapter(FragmentManager fm,CharSequence mTitles[], int mNumbOfTabsumb) {
super(fm);
this.Titles = mTitles;
this.NumbOfTabs = mNumbOfTabsumb;
}
#Override
public Fragment getItem(int position) {
if(position == 0)
{
FragmentForDay tab1 = FragmentSlide.newInstance(0);
return tab1;
}
else if(position == 1)
{
FragmentSlide tab2 = FragmentSlide.newInstance(1);
return tab2;
}
else
{
FragmentSlide tab3 = FragmentSlide.newInstance(2);
return tab3;
}
}
#Override
public CharSequence getPageTitle(int position) {
return Titles[position];
}
#Override
public int getCount() {
return NumbOfTabs;
}
}
And each of your slide tabs, called FragmentSlide here, can be inflated as a normal Fragment:
public class FragmentSlide extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_Slide, container, false);
// Inflate the layout for this fragment
return rootView;
}
public static FragmentSlide newInstance(int selectedIdForIndex) {
FragmentSlide fragment = new FragmentSlide();
Bundle args = new Bundle();
args.putInt(ARG_LAYOUT_ID, selectedIdForIndex);
fragment.setArguments(args);
return fragment;
}
}

my app crashes when I swipe from one fragment to another (error: canScrollHorizontally()' on a null object reference)

I've been trying to resolve this problem but with no result. My app is made up of 4 fragments, the second one with a recycler view. When I swipe from the first to the second my app instantly crashes. And in the logCat this error appears:
Attempt to invoke virtual method 'boolean android.support.v7.widget.RecyclerView$LayoutManager.canScrollHorizontally()' on a null object reference at android.support.v7.widget.RecyclerView.onInterceptTouchEvent(RecyclerView.java:2022)
Here's my code for the main activity:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
toolbar = (Toolbar) findViewById(R.id.app_bar);
if (toolbar != null) {
toolbar.setTitle("Quick!");
}
setSupportActionBar(toolbar);
fragmentList.add(HomeFragment.getInstance(0));
fragmentList.add(KartFragment.getInstance(1));
fragmentList.add(FavouriteFragment.getInstance(2));
fragmentList.add(ScannerFrag.getInstance(3));
pager = (ViewPager) findViewById(R.id.Pager);
pager.setAdapter(new myPagerAdapter(getSupportFragmentManager()));
tab = (SlidingTabLayout) findViewById(R.id.SlidingTab);
tab.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
#Override
public int getIndicatorColor(int position) {
return getResources().getColor(R.color.accentColor);
}
});
tab.setViewPager(pager);
}
class myPagerAdapter extends FragmentPagerAdapter {
String[] tabs;
public myPagerAdapter(FragmentManager fm) {
super(fm);
tabs = getResources().getStringArray(R.array.tabs);
}
#Override

}
#Override

}
public int getCount() {

}
}
Home fragment:
public class HomeFragment extends Fragment {
private Toolbar toolbar;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View layout;
layout = inflater.inflate(R.layout.home_layout, container, false);
toolbar = (Toolbar) layout.findViewById(R.id.subToolbar);
toolbar.setTitle("Dove mangi oggi?");
return layout;
}
public static HomeFragment getInstance(int position) {
HomeFragment frag = new HomeFragment();
Bundle args = new Bundle();
args.putInt("position", position);
frag.setArguments(args);
return frag;
}
}
KartFragment:
public class KartFragment extends Fragment {
private Toolbar toolbar;
private ItemAdapter ad;
private RecyclerView rv;
private ArrayList list = new ArrayList<>();
private static final String SAVELIST = "SAVELIST";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View layout;
if (savedInstanceState != null) {
list = savedInstanceState.getParcelableArrayList(SAVELIST);
} else {
list = KartObjectClass.listBuilder(10);
}
layout = inflater.inflate(R.layout.fragment_layout, container, false);
toolbar = (Toolbar) layout.findViewById(R.id.subToolbar);
toolbar.setTitle("I tuoi ordini:");
rv = (RecyclerView) layout.findViewById(R.id.list);
rv.setLayoutManager(new LinearLayoutManager(getActivity()));
ad = new ItemAdapter(list);
rv.setHasFixedSize(true);
rv.setAdapter(ad);
return layout;
}
#Override
public void onSaveInstanceState(Bundle outState) {
outState.putParcelableArrayList(SAVELIST, list);
super.onSaveInstanceState(outState);
}
public static KartFragment getInstance(int position) {
KartFragment frag = new KartFragment();
Bundle args = new Bundle();
args.putInt("position", position);
frag.setArguments(args);
return frag;
}
}
Favourite fragment:
public class FavouriteFragment extends Fragment {
private Toolbar toolbar;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View layout = null;
layout = inflater.inflate(R.layout.scanner_layout, container, false);
toolbar = (Toolbar) layout.findViewById(R.id.subToolbar);
toolbar.setTitle("I tuoi preferiti:");
return layout;
}
public static FavouriteFragment getInstance(int position) {
FavouriteFragment frag = new FavouriteFragment();
Bundle args = new Bundle();
args.putInt("position", position);
frag.setArguments(args);
return frag;
}
}

Try to set the LayoutManager before you set the Adapter on the RecyclerView.

I solved the error, the problem was that I had set a recycler view in the homeFragment XML. As I forgot to have it, I didn't call it in the onCreateView method and the app was crashing because no adapter was set.

Custom ListView in Viewpager

This is my page:

How can I put my Custom ListView in a fragment?
I tried to move the code in the switch(getArguments().getInt(ARG_SECTION_NUMBER)){ but there were many errors.
What should I do?
