Tab Fragment Button Click Send Data To More Than One Tabfragment

i have three tab fragments TAB1,TAB2 and TAB3. On TAB1 there is a button when when clicked it has to send data to TAB2 and TAB3 using interface and display data in the textView in

Solution 1:

In your Tab1ToTab3 method you're instanciating TabFragment3 with your second fragment :

TabFragment3fragment= (TabFragment3) adapter.getFragment(1);

replace it with

TabFragment3fragment= (TabFragment3) adapter.getFragment(2);

Solution 2:

// Update your getItem() method with this

@Overridepublic Fragment getItem(int position) {

        switch (position) {
            case0:
                Bundlebundle=newBundle();
                bundle.putString("YOUR_KEY","YOUR VALUE");
                TabFragment1tab1=newTabFragment1();
                tab1.setArguments(bundle);
                return tab1;
            case1:
                Bundlebundle2=newBundle();
                bundle2.putString("YOUR_KEY","YOUR VALUE");
                TabFragment2tab2=newTabFragment2();
                tab2.setArguments(bundle2);
                return tab2;
            case2:
                Bundlebundle3=newBundle();
                bundle3.putString("YOUR_KEY","YOUR VALUE");
                TabFragment3tab3=newTabFragment3();
                tab3.setArguments(bundle3);
                return tab3;
            case3:
                Bundlebundle4=newBundle();
                bundle4.putString("YOUR_KEY","YOUR VALUE");
                TabFragment4tab4=newTabFragment4();
                tab4.setArguments(bundle4);
                return tab4;
            default:
                returnnull;
        }

// Under TabFragment1, TabFragment2, TabFragment3, TabFragment4 Override onActivityCreated() to get your data String and setMenuVisibility(boolean menuVisible) to update view

publicstaticString data;


     @OverridepublicvoidonActivityCreated(@Nullable Bundle savedInstanceState) {
            super.onActivityCreated(savedInstanceState);
            Bundle bundle = getArguments();
            String yourValue = bundle.getString("YOUR_KEY");
imageView.setOnClickListener(newView.OnClickListener() {
                @OverridepublicvoidonClick(View v) {
                   TabFragment1.data="Update";
                   TabFragment2.data="Update";
                   TabFragment3.data="Update";
                   TabFragment4.data="Update";
    //update your current View from here
                }
            });
        }



     @OverridepublicvoidsetMenuVisibility(boolean menuVisible) {
            super.setMenuVisibility(menuVisible);
            if(menuVisible){
                //update your current View from here
            }
        }

by using this you can update all fragments data view from any fragment. click
