How can i load data on specific tab in android?

My task is to load data on 50th screen out of 100 screens in one tab activity and also to increment date on forward swipe and decrement date on backward swipe.
I wrote code to increment date and made 50th screen as my current screen but i don't know how to load that current date in 50th screen and to decrement date on backward swipe.
Here is my main activity:
public class MainActivity extends AppCompatActivity {
public static Tab2 self;
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager.setCurrentItem(50);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
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);
}
/**

public static class PlaceholderFragment extends Fragment {

*/
private static final String ARG_SECTION_NUMBER = "section_number";
public PlaceholderFragment() {
}
/**

* 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 int getCount() {
return 100;
}
#Override
public Fragment getItem(int position) {
//TabHost tabHost = Tab2.self.getTabHost();
//tabHost.setCurrentTab(0);
return Tab2.newInstance(position);
}
#Override
public CharSequence getPageTitle(int position) {
return "SECTION 3";
}
}
}
and my tab activity is
public class Tab2 extends Fragment {
private int position;
public Tab2() {
}
public static Tab2 newInstance(int position) {
Tab2 fragment = new Tab2();
Bundle args = new Bundle();
args.putInt("position", position);
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
position = getArguments().getInt("position");
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.tab2, container, false);
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Calendar c = Calendar.getInstance();
c.add(Calendar.DAY_OF_MONTH, position);
String dte = sdf.format(c.getTime()).toString();
TextView textView2 = getView().findViewById(R.id.textView2);
textView2.setText(dte);
}
}

If you want one tab to have specific data, you need to handle that case in the adapter
#Override
public Fragment getItem(int position) {
Fragment f = Tab2.newInstance(position);
if (position == specificPosition) {
Bundle args = new Bundle();
// put into args...
f.setArguments(args);
}
return f;
}
Regarding swipe direction, I think you need to attach the listener on the ViewPager.

This should work.
In your fragment:
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Calendar c = Calendar.getInstance();
c.setTime(new Date());
c.add(Calendar.DATE, position);
String dte = sdf.format(c.getTime()).toString();
TextView textView2 = getView().findViewById(R.id.textView2);
textView2.setText(dte);
}
Hope it helps

How to initialize a Listview inside a fragment of Tab view android?

I have an activity which has three tabs. One fragment for each tabs. In the xml of the fragment layout I have a listview. I need to initialize this list view and populate it with data from the firebase. How can I do that?
My activity code is
public class AccountActivity extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_account);
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) {
startActivity(new Intent(AccountActivity.this,AddLeaveActivity.class));
}
});

*/
public interface OnFragmentInteractionListener {
// TODO: Update argument type and name
void onFragmentInteraction(Uri uri);
}
}
Here the problem is not only the data is populating but also its not setting the text of the textview. But the data is populating and listing if I am using an activity. So I guess the data retrieving code is correct.
So where can is initialize the listview inside a fragment?

Android FragmentPagerAdapter Passing Wrong Position to My Fragment

Relevant Code:
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() {
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Nachrichten";
case 1:
return "Sport";
case 2:
return "Kultur";
}
return null;
}
}
public static class PlaceholderFragment extends Fragment {
private static final String ARG_SECTION_NUMBER = "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;
}
public PlaceholderFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
ListView list = (ListView) rootView.findViewById(R.id.list);
Log.d("onCreateView()","Section number: " + getArguments().getInt(ARG_SECTION_NUMBER));
if(Feeds.size() != 0) {
try {
NewsAdapter adapter = new NewsAdapter(Nachrichtenleicht.getAppContext(), Feeds.get(getArguments().getInt(ARG_SECTION_NUMBER)));
list.setAdapter(adapter);
} catch (Exception e) {
e.printStackTrace();
}
}
return rootView;
}
}
Whenever I click on tab 1 ("Nachrichten" - News) the number 1 is logged, and the correct feed is displayed.
Whenever I click on tab 2 ("Sport") the number 3 is logged, and nothing is displayed.
Whenever I click on tab 3 ("Kultur" - Culture) nothing is logged, and the correct feed is displayed.
I know that all of the feeds have correctly been populated because I have tried switching around the order in the networking code, and the "Sport" feed would show in places 1 or 3, but nothing would show in spot 2. I have also tried getting the current position from the view pager to no avail.

Android: ViewPager displays only first fragment, other pages blank

I have a ViewPager that displays a series of FoodItem as Fragments. That part works just fine.
Now, I want to have a function such that if a user clicks on a button, they can view more information about that FoodItem.
For that, I want to replace the clicked Fragment with another Fragment. I modified this code here to suit my purpose. It works -- when I click the button, it replaces that certain Fragment. But it only displays and works for one Fragment. Other fragments are blank entirely.
Here's my adapter and fragments:
public class SectionsPagerAdapter extends FragmentStatePagerAdapter {
private ArrayList<FoodItem> items;
public SectionsPagerAdapter(FragmentManager fm, ArrayList<FoodItem> items) {
super(fm);
this.items = items;
}
#Override
public Fragment getItem(int position) {
System.out.println("PRINT: POS " + position);
RootFragment f = new RootFragment();
return f.newInstance(position);
}
#Override
public int getCount() {
return items.size();
}
public class PlaceholderFragment extends Fragment{
private final String ARG_SECTION_NUMBER = "section_number";
public PlaceholderFragment newInstance(int sectionNumber) {
PlaceholderFragment fragment = new PlaceholderFragment();
System.out.println("PRINT: INSTANCE" + sectionNumber);
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
public PlaceholderFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_card_layout, container, false);
singleItem = items.get(getArguments().getInt(ARG_SECTION_NUMBER));
// populate views here
//Below is the button for replacing the Fragment with another Fragment.
Button testMore = (Button) view.findViewById(R.id.testMore);
testMore.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FragmentTransaction trans = getFragmentManager()
.beginTransaction();
trans.replace(R.id.root_frame, new MoreInfoFragment().newInstance(getArguments().
getInt(ARG_SECTION_NUMBER)));
trans.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
trans.addToBackStack(null);
trans.commit();
}
});
return view;
}
}
public class MoreInfoFragment extends Fragment {
private final String ARG_SECTION_NUMBER = "section_number";
public MoreInfoFragment newInstance(int sectionNumber) {
MoreInfoFragment fragment = new MoreInfoFragment();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
public MoreInfoFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.more_info_layout, container, false);
singleItem = items.get(getArguments().getInt(ARG_SECTION_NUMBER));
//populate views here
return view;
}
}
public class RootFragment extends Fragment {
private static final String TAG = "RootFragment";
private final String ARG_SECTION_NUMBER = "section_number";
public RootFragment newInstance(int sectionNumber) {
RootFragment fragment = new RootFragment();
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 view = inflater.inflate(R.layout.root_fragment, container, false);
FragmentTransaction transaction = getFragmentManager()
.beginTransaction();
transaction.replace(R.id.root_frame, new PlaceholderFragment().newInstance(getArguments().
getInt(ARG_SECTION_NUMBER)));
System.out.println("PRINT: ROOT" + getArguments().getInt(ARG_SECTION_NUMBER));
transaction.commit();
return view;
}
}
}
Here's my Main Activity:
private ViewPager mViewPager;
private static ArrayList<FoodItem> sample;
private PagerContainer mContainer;
public CardLayout(){
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
setContentView(R.layout.activity_card_layout);
//Sample array
sample = new ArrayList<>();
sample.add(new FoodItem("French Fries", "Super delicious and crispy!"))
sample.add(new FoodItem("Burger", "Made with real Krabby Patty"))
sample.add(new FoodItem("Pickles", "So green")) // This is the only one that displays
//PagerContainer is a FrameLayout that has a ViewPager as a child.
//I want my ViewPager to display edges of the previous and next part so
//PagerContainer is used for that purpose.
mContainer = (PagerContainer) findViewById(R.id.pager_container);
mViewPager = (ViewPager) findViewById(R.id.viewPager);
// This is to adjust the viewpager according to size of screen
mContainer.getViewTreeObserver().
addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#SuppressLint("NewApi")
#SuppressWarnings("deprecation")
#Override
public void onGlobalLayout() {
height = mContainer.getHeight();
double heightSize = height * 0.8;
height = (int) heightSize;
double widthSize = height*0.6;
width = (int) widthSize;
mViewPager.setLayoutParams(new FrameLayout.LayoutParams(width, height, Gravity.CENTER));
mViewPager.setPageMargin(width /30);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN)
mContainer.getViewTreeObserver().removeOnGlobalLayoutListener(this);
else
mContainer.getViewTreeObserver().removeGlobalOnLayoutListener(this);
}
});
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager(), sample);
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager.setOffscreenPageLimit(mSectionsPagerAdapter.getCount());
mViewPager.setClipChildren(false);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
finish();
}
});
}
Oh, the Fragment that's displaying is not even the first one in my ArrayList! It's the last.
I feel like I'm missing something obvious but I've looked through this code about 10 times and I still couldn't find what could have prevented the other pages from displaying.
For example, this is how the first page looks like:
If I slide to the second page, it's totally white (my background color for root_fragment)
And that goes for every fragments after.
Do you guys have any ideas/suggestions?

Override the method getItem() in your SelectionsPageAdapter
#Override
public Fragment getItem(int position) {
// if the position is 0 we are returning the First tab
if (position == 0)
{
Fragment tab1 = new PlaceholderFragment ();
return tab1;
} else if (position == 1)
{
Fragment tab2 = new MoreInfoFragment ();
return tab2;
} else if (position == 2) {
Fragment tab3 = new RootFragment ();
return tab3;
}
}

Android Swipe View help needed

I have a swipe Activity, with 2 swipe pages, I added the content for the first page and on the second page the content is duplicated, how can I set different content to the second page in my swipe view?

extras = getIntent().getExtras();
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(this).build();
imageLoader = ImageLoader.getInstance();
imageLoader.init(config);
//Setup options for ImageLoader so it will handle caching for us.
options = new DisplayImageOptions.Builder()
.cacheInMemory()
.cacheOnDisc()
.build();

Android Developers site really has very good explanation of ViewPager. You should check it out:
http://developer.android.com/training/animation/screen-slide.html
Here is an example I wrote:
activity_screen_slide.xml
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Java Code:
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
...
public class ScreenSlidePagerActivity extends FragmentActivity {
private static final int NUM_PAGES = 2;
private ViewPager mPager;
private PagerAdapter mPagerAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_screen_slide);
mPager = (ViewPager) findViewById(R.id.pager);
mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
mPager.setAdapter(mPagerAdapter);
}
#Override
public void onBackPressed() {
if (mPager.getCurrentItem() == 0) {
super.onBackPressed();
} else {
mPager.setCurrentItem(mPager.getCurrentItem() - 1);
}
}
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
public ScreenSlidePagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
//Create these fragments with your preferable names
switch (position) {
case 0:
return new ScreenSlidePageFragment();
case 1:
return new ScreenSlidePageFragment2();
default:
break;
}
}
#Override
public int getCount() {
return NUM_PAGES;
}
}
}
And here is one of your views that should look like it where fragment_ screen_slide_page is one of your layouts:
import android.support.v4.app.Fragment;
...
public class ScreenSlidePageFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_screen_slide_page, container, false);
return rootView;
}
}
You should really read the android developers site for further details.

You can return different fragments like this:
#Override
public Fragment getItem(int position) {
if (position == 0) {
return PlaceholderFragment.newInstance(position + 1);
} else {
return anotherFragment.newInstance();
}
}
If you want to use the same Fragment, you can change the content depending on the position you are passing to the fragment.
