Communication between swipe view Tabs

i followed this article http://www.truiton.com/2015/06/android-tabs-example-fragments-viewpager/ to implement swipe view and it work nice. So now i want to add button on Tab1 and when clicked has to send data to Tab2.
I know there is the issue of using interface but honestly i don't know how to add it on these codes and work provide am completely new to the android.
so far i have tried my best on these links Communication between SlidingTabLayout tabs, How to pass data from one swipe tab to another? and How can I communicate/pass data through different Fragments with Swipe Tab? but i fail.
Any one help please to make it work on every stage , i mean from Tab1 ->Mainactivity->Tab2
thanks alot
Here are the codes after i edit the question
Fragment1
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class TabFragment1 extends Fragment implements AdapterView.OnItemSelectedListener{
Button send;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v= inflater.inflate(R.layout.tab_fragment_1, container, false);
send=(Button)v.findViewById(R.id.send);
send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// value to be sent to the TabFragment2 on button click
String value=" My Data";
}
});
return v;
}
}
Fragment2
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class TabFragment2 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.tab_fragment_2, container, false);
//Display value from TabFragment1
textview.setText(value);
}
}
Interface class
public Interface FragmentCommunication
{
public void printMessage(String message);
}
MainActivity
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity implements FragmentCommunication{
#Override

setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter
(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
public void printMessage(String message)
{
Toast.makeText(MainActivity.this,message,Toast.LENGTH_LONG).show();
}
}
Adapter Class
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;
public class PagerAdapter extends FragmentStatePagerAdapter {
int mNumOfTabs;
public PagerAdapter(FragmentManager fm, int NumOfTabs) {
super(fm);
this.mNumOfTabs = NumOfTabs;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
TabFragment1 tab1 = new TabFragment1();
return tab1;
case 1:
TabFragment2 tab2 = new TabFragment2();
return tab2;
default:
return null;
}
}
#Override
public int getCount() {
return mNumOfTabs;
}
}

so after posting more code I'm answering:
Implement some FragmentCommunication for both your Fragments:
//public class TabFragment1 extends Fragment implements FragmentCommunication{
public class TabFragment2 extends Fragment implements FragmentCommunication{
//public static final String TAG="TabFragment1";
public static final String TAG="TabFragment2";
...
#Override
public void onActivityCreated (Bundle savedInstanceState){
super.onActivityCreated(savedInstanceState);
if(getActivity() instanceOf MainActivity)
((MainActivity) getActivity()).registerFragmentCommunication(
TAG, this);
}
#Override
public void printMessage(String message){
Toast.makeText(getActivity(), TAG+" says: "+message,
Toast.LENGTH_SHORT).show();
}
}
note this line inside onActivityCreated:
((MainActivity) getActivity()).registerFragmentCommunication(TAG, this);
this means implemented FragmentCommunication, TAG will be unique key/name of Fragment and whole method is registration of your interface in Activity. so now you have to add registerFragmentCommunication method to your MainActivity and keep reference to passed interfaces, e.g. in HashMap:
HashMap<String, FragmentCommunication> fragmentCommunications =
new HashMap<String, FragmentCommunication>();
...
public void registerFragmentCommunication(String key, FragmentCommunication fc){
fragmentCommunications.put(key, fc);
}
so now you can access each FragmentCommunication of both fragments from your MainActivity, e.g by using method like this:
public void callFragmentCommunication(String key, String msg){
if(fragmentCommunications.get(key)!=null)
fragmentCommunications.get(key).printMessage();
}
callFragmentCommunication(TabFragment1.TAG, "hi!");
callFragmentCommunication(TabFragment2.TAG, "hi!");
method is public, so Fragments can call it simply like this:
//inside TabFragment1
if(isAdded() && getActivity()!=null &&
getActivity() instanceOf MainActivity &&
!getActivity().isFinishing())
((MainActivity) getActivity()).callFragmentCommunication(
TabFragment2.TAG, "hi!");
this will show Toast with text: "TabFragment2 says: hi!", which was called inside TabFragment1. now you may pass another kind of data as well :)
there is much more methods like communicating through FragmentStatePagerAdapter like here, passing Bundle arguments where fragments are initialized, additional feedback interfaces (e.g. returning true/false when message was passed) etc. Above is just very simplified way, good luck with improving it! :)

Tabs with Icons using ViewPager, How to layout them? by Attaching Some Layout File

I am new to Android, Designing an Android Application that contains "Tabs".
I have designed this:
But I want to design like this,
I think there must be way, as like of populating lists using Custom Adapters, But I am not finding any thing to do this, the tutorials that are available on Android Web are out of scope of my mind, because I am new..
My code:
Tabs.xml
Tabs.java
package com.example.medbleep;
import TabsManager.TabPagerAdapter;
import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.widget.ImageView;
import android.widget.TextView;
public class Tabs extends FragmentActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private TabPagerAdapter mAdapter;
private android.app.ActionBar actionBar;
private int numberOfTabs = 5;
// Tab titles
private int[] tabIcons = {R.drawable.home,R.drawable.home,R.drawable.home,R.drawable.home,R.drawable.home,R.drawable.home};
private String[] tabText = { "Home", "units", "conferences", "couses", "more" };
ImageView imageView;
TextView textView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabs);
imageView = (ImageView)findViewById(R.id.tab_icon);
textView = (TextView)findViewById(R.id.tab_title);
// Initialization
viewPager = (ViewPager) findViewById(R.id.pager);
viewPager.setBackgroundColor(getResources().getColor(R.color.darkLoginBlue));
actionBar = getActionBar();
mAdapter = new TabPagerAdapter(getSupportFragmentManager(),
numberOfTabs);
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (int i = 0; i<5 ; i++) {
actionBar.addTab(actionBar.newTab().setText(tabText[i])
.setIcon(getResources().getDrawable(tabIcons[i]))
.setTabListener(this));
//actionBar.addTab(actionBar.newTab().setCustomView(R.layout.tab_layout).setText(tabText[i]).setIcon(tabIcons[i]).setTabListener(this));
//actionBar.setLogo(tabIcons[4]);
//actionBar.setIcon(tabIcons[i]);
//actionBar.setTitle(tabText[i]);
}
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabReselected(Tab arg0, FragmentTransaction arg1) {
// TODO Auto-generated method stub
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction arg1) {
// TODO Auto-generated method stub
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab arg0, FragmentTransaction arg1) {
// TODO Auto-generated method stub
}
}
TabPagerAdapter.java
package TabsManager;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;
public class TabPagerAdapter extends FragmentStatePagerAdapter{
int mNumOfTabs;
public TabPagerAdapter(FragmentManager fm, int NumOfTabs) {
super(fm);
this.mNumOfTabs = NumOfTabs;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
HomeTabFragment homeTabFragment = new HomeTabFragment();
return homeTabFragment;
case 1:
UnitTabFragment unitTabFragment = new UnitTabFragment();
return unitTabFragment;
case 2:
ConferencesTabFragment conferencesTabFragment = new ConferencesTabFragment();
return conferencesTabFragment;
case 3:
CoursesTabFragment coursesTabFragment = new CoursesTabFragment();
return coursesTabFragment;
case 4:
MoreTabFragment moreTabFragment = new MoreTabFragment();
return moreTabFragment;
default:
return null;
}
}
#Override
public int getCount() {
return mNumOfTabs;
}
}

For making this, your have to create Custom Adaptor and set width and height According to your requirement of each tab.

Android sliding tabs, Fragment_Collection_Object Error

am following the Android Developers website to add sliding tabs to my Android app for my project, I am stuck with this one error and do not understand the problem, I know it has something to do with calling the correct Fragment layout, I am doing exactly what the tutorial tells me too, have any of you guys got any information to solve this, thank you.

The problem you are facing is because of the missing xml file in the layout folder of project/res
Go to http://developer.android.com/training/implementing-navigation/lateral.html
Click on "download the sample app" and unzip it. Add the EffectiveNavigation\res\layout\fragment_collection_object.xml to you project\res\layout. This,I guess will solve the problem.

Android : refresh fragment with dynamic list using ViewPager and ActionbarTab

I'm quite new to Android. I'm stuck with this issue for a few days now.
I'm using the new google's Template of Action bar Tab with swipe (ViewPager).
Inside each fragment, I want to display a dynamic list of cards (with cardslib : https://github.com/gabrielemariotti/cardslib). The data for the cards come from an asyncTask which is fetching data from an url.
This is my problem : When I launch the app, the first View is display, but the ViewPager prepare the view for the second page, so the async task for the second screen is launch too. And the cards of the second screen are added to the first one.
Then if i swipe to the second screen, nothing is displayed, and the async task for the third screen is launch. So if swipe to the thrid screen, nothing... And then if i switch again to the second screen, the cards with data of the first screen are displayed... A real mess !
I think I have a probleme with the onCreate, onCreateView, or something like that. Maybe the code is sometimes not at the right place.. I don't know. I tried a lot of small modofication, but nothing worked. (but it worked like this with just action bar tab and without the ViewPager).
Thanks

Thanks #GabrieleMariotti, it helped ! In fact I already tried to use different classes for the different fragments, but I forget to give diferent IDs to my cardsLists. It solved the problem. Btw, good job for your lib, it is awesome.
So for the next one : create differents classes for all your differents fragments. They have to use differents layout, and the cardsList have to use differents ID.

Android Swipe tabs Issue: Can't seem to update the UI and the result comes repeated n times

I'm using two classes. One for the background service where i'm doing several of gatherings of information, and the other I decided to use a swipe tab view to manage and organize my information/data. In the background service (like I said) i'm retrieving information (mostly string types) and sending them via intent to the Main Activity, this activity receives it via a broadcastreceiver (this part works fine). Now the problem i'm having is that when i try to distribute the information the the diferent tabs, it comes repeated and doesn't seem to refresh now my most crucial problem is the reapeating information part. Going to place my code and see if any one of you brilliant minds :D can help me. I hope you can.
