Calling API when swiping tabs

I have a tab layout with 3 tabs.Each one of the tabs need to display some data from API calling (I’m using Retrofit).

So , I have the main activity when user opens that activity I fetch the data for the first tab then display the view

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); context = this; if (Application.isConnected()) { getTrips(); } else { Toast.makeText(this , "No internet Connection" , Toast.LENGTH_LONG).show(); setContentView(R.layout.no_internet_connection); } }

So in the success of the API call I inflate the view as below

public void inflatingView () { setContentView(R.layout.activity_mytrip); context = this; tvTitle = findViewById(R.id.tv_title); tabLayout = findViewById(R.id.tablayout); tvTitle.setText("Trips"); tabLayout.addTab(tabLayout.newTab().setText("My Trips")); tabLayout.addTab(tabLayout.newTab().setText("Unclosed Trips")); tabLayout.addTab(tabLayout.newTab().setText("UnApproved Trips")); viewPager = findViewById(R.id.viewpager); myTripAdapter = new MyTripAdapter(getSupportFragmentManager(),tabLayout.getTabCount()); viewPager.setAdapter(myTripAdapter); viewPager.setOffscreenPageLimit(3); tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() { @Override public void onTabSelected(TabLayout.Tab tab) { switch (tabLayout.getSelectedTabPosition()) { case 0 : Log.d("test" , "first tab"); break; case 1 : Log.d("test" , "Second tab"); getTab2Data(); break; case 2 : Log.d("test" , "Third tab"); break; } viewPager.setCurrentItem(tabLayout.getSelectedTabPosition()); } @Override public void onTabUnselected(TabLayout.Tab tab) { } @Override public void onTabReselected(TabLayout.Tab tab) { } }); viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout)); }

So , The data for first fragment in first tab is obtained , My problem is with fragment 2 and 3.I only want to call the API when user swiping. As you see above I tried to detect when user swipe to second tab then I call method to fetch data but unfortunately it’s now working.

Do you have any idea on how to do this?

2 Answers

Use this method in your fragment to get visibility state of fragment and then call your api thre.

@Override boolean getUserVisibleHint() { super.getUserVisibleHint() boolean isVisibleToUser=super.getUserVisibleHint() if(isVisibleToUser){ //call api here } return isVisibleToUser }

You should call API’s inside the fragment probably in setUserVisibleHint method in android

boolean _areLecturesLoaded = false; @Override public void setUserVisibleHint(boolean isVisibleToUser) { super.setUserVisibleHint(isVisibleToUser); if (isVisibleToUser && !_areLecturesLoaded ) { loadYourRetrofitData(); //Load your data here _areLecturesLoaded = true; } }
