同一片段中的多个ViewPager

Question

I have created two customViews classes,Having view pager in each customview class. Now I want to include these two custom view classes in same activity. The problem is one pagerview working fine, but the other pager is not showing any view?

Anyone knowing how to add multiple viewpager in same activity.?
Please help.

My customeViews are

public class TrainingResultsTopView extends LinearLayout {

    Context context;
    View rootView;
    private ViewPager viewPager;
    private TabLayout tabLayout;
    private PieChartFragment monthFragment;
    private PieChartFragment annualFragment;
    private PieChartFragment allTimeFragment;

    public TrainingResultsTopView(Context context) {
        super(context);
        initView(context);
    }

    public TrainingResultsTopView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initView(context);
    }

    public TrainingResultsTopView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initView(context);
    }

    public TrainingResultsTopView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
        initView(context);
    }

    private void initView(Context context) {
        this.context = context;
        LayoutInflater inflater = LayoutInflater.from(context);
        rootView = inflater.inflate(R.layout.dashboard_top_view, this, true);
        viewPager = (ViewPager) rootView.findViewById(R.id.viewpager);
        viewPager.setOffscreenPageLimit(3);
        tabLayout = (TabLayout) rootView.findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);

        setFragmentsToPager();
        customizeTabs(inflater);
    }


//    private void bindDataToFragments() {
//        monthFragment.bindLeaderboardData(leaderboardModelMonthly);
//        annualFragment.bindLeaderboardData(leaderboardModelAnnually);
//        allTimeFragment.bindLeaderboardData(leaderboardModelAllTime);
//    }

    private void setFragmentsToPager() {
        ViewPagerAdapter adapter = new ViewPagerAdapter(((AppCompatActivity)context).getSupportFragmentManager());
        monthFragment = new PieChartFragment();
        annualFragment = new PieChartFragment();
        allTimeFragment = new PieChartFragment();
        adapter.addFragment(monthFragment, "Last 30 Days");
        adapter.addFragment(annualFragment, "This Year");
        adapter.addFragment(allTimeFragment, "All-Time");
        viewPager.setAdapter(adapter);
    }

    private void customizeTabs(LayoutInflater inflater) {
        LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        lp.setMargins(0,0,0,0);

        TextView tv1 = (TextView) inflater.inflate(R.layout.textview_dashboard_tab, null);
        tv1.setTypeface(Constants.appTypeface);
        tv1.setText("Last 30 Days");
        tv1.setGravity(Gravity.CENTER);
        tv1.setLayoutParams(lp);
        TextView tv2 = (TextView) inflater.inflate(R.layout.textview_dashboard_tab, null);
        tv2.setTypeface(Constants.appTypeface);
        tv2.setText("This Year");
        tv2.setGravity(Gravity.CENTER);
        tv2.setLayoutParams(lp);
        TextView tv3 = (TextView) inflater.inflate(R.layout.textview_dashboard_tab, null);
        tv3.setTypeface(Constants.appTypeface);
        tv3.setText("All-Time");
        tv3.setGravity(Gravity.CENTER);
        tv3.setLayoutParams(lp);

        tabLayout.getTabAt(0).setCustomView(tv1);
        tabLayout.getTabAt(1).setCustomView(tv2);
        tabLayout.getTabAt(2).setCustomView(tv3);
    }


}






And

public class ActionBeaconRatingTopView extends LinearLayout {

    Context context;
    View rootView;
    private CustomViewPager viewPager;
    private TabLayout tabLayout;
    private ActionBeaconRatingFragment monthFragment;
    private ActionBeaconRatingFragment annualFragment;
    private ActionBeaconRatingFragment allTimeFragment;

    public ActionBeaconRatingTopView(Context context) {
        super(context);
        initView(context);
    }

    public ActionBeaconRatingTopView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initView(context);
    }

    public ActionBeaconRatingTopView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initView(context);
    }

    public ActionBeaconRatingTopView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
        initView(context);
    }

    private void initView(Context context) {
        this.context = context;
        LayoutInflater inflater = LayoutInflater.from(context);
        rootView = inflater.inflate(R.layout.dashboard_top_view, this, true);

        viewPager = (CustomViewPager) rootView.findViewById(R.id.viewpager);
        viewPager.setOffscreenPageLimit(3);
        viewPager.setPagingEnabled(false);
        tabLayout = (TabLayout) rootView.findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);

        setFragmentsToPager();
        customizeTabs(inflater);
    }


//    private void bindDataToFragments() {
//        monthFragment.bindLeaderboardData(leaderboardModelMonthly);
//        annualFragment.bindLeaderboardData(leaderboardModelAnnually);
//        allTimeFragment.bindLeaderboardData(leaderboardModelAllTime);
//    }

    private void setFragmentsToPager() {
        ViewPagerAdapter adapter = new ViewPagerAdapter(((AppCompatActivity)context).getSupportFragmentManager());
        monthFragment = new ActionBeaconRatingFragment();
        annualFragment = new ActionBeaconRatingFragment();
        allTimeFragment = new ActionBeaconRatingFragment();
        adapter.addFragment(monthFragment, "Last 30 Days");
        adapter.addFragment(annualFragment, "This Year");
        adapter.addFragment(allTimeFragment, "All-Time");
        viewPager.setAdapter(adapter);
    }

    private void customizeTabs(LayoutInflater inflater) {
        LayoutParams lp = new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        lp.setMargins(0,0,0,0);

        TextView tv1 = (TextView) inflater.inflate(R.layout.textview_dashboard_tab, null);
        tv1.setTypeface(Constants.appTypeface);
        tv1.setText("Last 30 Days");
        tv1.setGravity(Gravity.CENTER);
        tv1.setLayoutParams(lp);
        TextView tv2 = (TextView) inflater.inflate(R.layout.textview_dashboard_tab, null);
        tv2.setTypeface(Constants.appTypeface);
        tv2.setText("This Year");
        tv2.setGravity(Gravity.CENTER);
        tv2.setLayoutParams(lp);
        TextView tv3 = (TextView) inflater.inflate(R.layout.textview_dashboard_tab, null);
        tv3.setTypeface(Constants.appTypeface);
        tv3.setText("All-Time");
        tv3.setGravity(Gravity.CENTER);
        tv3.setLayoutParams(lp);

        tabLayout.getTabAt(0).setCustomView(tv1);
        tabLayout.getTabAt(1).setCustomView(tv2);
        tabLayout.getTabAt(2).setCustomView(tv3);
    }

I want to add these views in in same fragment. At a time one will be visible.
