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() {
}
/**

*/
public static PlaceholderFragment newInstance(int sectionNumber) {
PlaceholderFragment fragment = new PlaceholderFragment();

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

Depends where you are calling it from but I suspect it is because you are calling this from the fragment when getSupportFragmentManager is a method on the AppCompatActivity class

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

}
}
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 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?

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.

onItemClickListener in ListView not working

I have a ListView within a ListFragment, and currently I just want a click on any of the items to go to ProblemActivity.class, which is currently a barebones 'HelloWorld' activity. Problem is I don't think the onItemClickListener is firing, and I'm not sure why, as I'm an Android novice. Any ideas?

Try this..
Change this..
ListView listView = (ListView) rootView.findViewById(android.R.id.list);
to
ListView listView = getListView();
EDIT
Add below code after onCreateView
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(getActivity(), R.layout.list_probs,PROBLEMS));
ListView listView = getListView();
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int position,
long id) {
Intent intent = new Intent(MainFragment.this.getActivity(), ProblemActivity.class);
startActivity(intent);
}
});
}

Apart for the other answer you directly add ListItem click event like
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
Toast.makeText(getActivity(), PROBLEMS[(int) id],Toast.LENGTH_SHORT).show();
}
