Question

Creating app in which i want to pass bundle data from one tab fragment to another.I have created two tab and getting list in one fragment but now i want to select item from Recyclerview list using checkbox and set this selected item to another tab fragment on swipe.Using viewpager for creating tab.In second tab fragment set bundle and in first tab fragment get bundle but not working.

In second fragment i set bundle

    Bundle data = new Bundle();
    data.putString("name",contactArrayList.get(position).getContactName());
    data.putString("mobile",contactArrayList.get(position).getContactNumber());
    Fragment fragment = FragmentInfo.newInstance(1);
    fragment.setArguments(data);

In first fragment i get bundle

if (bundle != null) {
       String name = bundle.getString("name");
       String mobile = bundle.getString("mobile");
        // object of Model Class
        mydata.setName(name);
        mydata.setMobile(mobile);
        myDataArrayList.add(mydata);

    }

try this:

create a mechanism to access the tag across fragments via the main activity, . - Call getTag() in onCreateView() of FragmentB . Then pass it to the main activity. When FragmentA need to pass something to FragmentB , it retrieve it from MainActivity .

 public static class TabsAdapter extends FragmentPagerAdapter
  implements ActionBar.TabListener, ViewPager.OnPageChangeListener {

  private final Context mContext;
        private final ActionBar mActionBar;
        private final ViewPager mViewPager;
        private final ArrayList<TabInfo> mTabs = new ArrayList<TabInfo>();

        static final class TabInfo {
            private final Class<?> clss;
            private final Bundle args;

            TabInfo(Class<?> _class, Bundle _args) {
                clss = _class;
                args = _args;
            }
        }

  public TabsAdapter(FragmentActivity activity, ViewPager pager) {
   super(activity.getSupportFragmentManager());
            mContext = activity;
            mActionBar = activity.getActionBar();
            mViewPager = pager;
            mViewPager.setAdapter(this);
            mViewPager.setOnPageChangeListener(this);
        }

  public void addTab(ActionBar.Tab tab, Class<?> clss, Bundle args) {
            TabInfo info = new TabInfo(clss, args);
            tab.setTag(info);
            tab.setTabListener(this);
            mTabs.add(info);
            mActionBar.addTab(tab);
            notifyDataSetChanged();
        }

  @Override
  public void onPageScrollStateChanged(int state) {
   // TODO Auto-generated method stub

  }

  @Override
  public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
   // TODO Auto-generated method stub

  }

  @Override
  public void onPageSelected(int position) {
   // TODO Auto-generated method stub
   mActionBar.setSelectedNavigationItem(position);
  }

  @Override
  public void onTabReselected(Tab tab, FragmentTransaction ft) {
   // TODO Auto-generated method stub

  }

  @Override
  public void onTabSelected(Tab tab, FragmentTransaction ft) {
   Object tag = tab.getTag();
            for (int i=0; i<mTabs.size(); i++) {
                if (mTabs.get(i) == tag) {
                    mViewPager.setCurrentItem(i);
                }
            }
  }

  @Override
  public void onTabUnselected(Tab tab, FragmentTransaction ft) {
   // TODO Auto-generated method stub

  }

  @Override
  public Fragment getItem(int position) {
   TabInfo info = mTabs.get(position);
            return Fragment.instantiate(mContext, info.clss.getName(), info.args);
  }

  @Override
  public int getCount() {
   return mTabs.size();
  }

 }
