Swipe Between Two Fragments with Re-Creating it

I have Two Fragments one will Send integers to the Sql database, and the other will display them both fragments are working fine. However, when I send an integer to the database and I swipe to the display fragment it will not refresh until push a button, I would like to make it automatically once I move to the fragment please:
Here is my Main Activity:
public class MainActivity extends AppCompatActivity {
int index;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
SectionsPagerAdapter mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
ViewPager mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager.getAdapter().notifyDataSetChanged();
mViewPager.setOffscreenPageLimit(0);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
//------------- Intlize Fragment ----//
Dash dash = new Dash();
getSupportFragmentManager().beginTransaction().add(R.id.dashfragment, dash).commit();
}
#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) {
int id = item.getItemId();
if (id == R.id.action_settings) {
Intent i = new Intent(this, AboutMe.class );
startActivity(i);
}
return super.onOptionsItemSelected(item);
}
public static class PlaceholderFragment extends 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);
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) {
switch (position){
case 0:
Dash dash = new Dash();
return dash;
case 1:
Caluclate caluclate = new Caluclate();
return caluclate;
case 2:
AskMe askMe = new AskMe();
return askMe;
case 3:
TeamPicker teamPicker = new TeamPicker();
return teamPicker;
}
return null;
}
i read many solutions but i couldn't figure it out.

You could do something like
if (fragment.isVisible()) {
refreshItFirst;
}
BTW why take a fragment for insertions of Db - there is a helper class?
The method isVisible() shoud help you.
Look at this post Replace Fragment inside a ViewPager

ListView is repopulated when pressed back button from Activity B to go to Activity A and again went to Activity B by explicit intent

From MainActivity when i goto HolidayActivity by using explicit intent i am able to see the LisView is populated with distinct elements within the fragment, After pressing back button i again goto MainActivity and when i again try to open HolidayActivity the ListView is populated again with duplicate elements, I have used LoaderManager, so when device is rotated there is no duplicate elements, the problems occurs only when i switch between activities as described above. I have also tried to Override methos onKeyDown() and onBackPresses() but nothing seems to work out. Point to be noted out here is that i am fetching the list items from server.

Android - Tab items are not being created

I' am following a tutorial learning how to do a tab layout. I don't know what I did in the following code that it doesn't output the tabs. When the app runs, I don't see the tab item. Everything else works.

// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
tabs = (TabLayout) findViewById(R.id.tabs);
tabs.setupWithViewPager(container);
tabs.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener(){

This is your problem.
ViewPager container;
...
private ViewPager mViewPager;
...
tabs.setupWithViewPager(container);
You're declaring two ViewPagers, but you're only initializing one, and trying to setup the TabLayout with the null one.
Remove the ViewPager container; declaration, and change the setup call to:
tabs.setupWithViewPager(mViewPager);
Also, you don't need to set the OnTabSelectedListener on the TabLayout yourself. The setupWithViewPager() method will handle that for you.

there is no tab to show. use this :
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));

activity with Viewpager android

I'm writing application with fragments and Viewpager.
I've got a problem because on each fragment is the same text.
I don't known how to refer to only one fragment.
Could someone give me any advice how to do it?
public class Main2Activity extends AppCompatActivity {
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_main2);
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);
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

menu.add(300, 300, 300, "Fragment 2");
return true;
}

// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long

message="Example text";

return rootView;
}
}
/**

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 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:

}

}
}
}

By creating instance of your fragment, you put arguments in Bundle
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
You can read them in onCreateView
sectionNumber = bundle.getInt(ARG_SECTION_NUMBER);
Then, for instance, change your text
message="Example text" + sectionNumber;

How do I add text and other things in tabs 2 and three?

I'm using Android Studios tabbed activity template with ActionBar Tabs, I have a slight problem. I want to be able to add different texts into the different tabs however I get the same text on all tabs. How would I go by doing this?
I have read through all the comments on the code yet still can't find how the different tabs are linked.
