如何使用TabLayout将数据从活动传递到片段

public void setData(String data) {
    // 将数据传递给片段
    MyFragment fragment = (MyFragment) getSupportFragmentManager().findFragmentByTag("fragment_tag");
    if (fragment != null) {
        fragment.updateData(data);
    }
}

<android.support.design.widget.TabLayout
    android:id="@+id/tab_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabMode="fixed"
    app:tabGravity="fill" />

<android.support.v4.view.ViewPager
    android:id="@+id/view_pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

TabLayout tabLayout = findViewById(R.id.tab_layout);
ViewPager viewPager = findViewById(R.id.view_pager);

viewPager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
tabLayout.setupWithViewPager(viewPager);

public class MyPagerAdapter extends FragmentPagerAdapter {
    private String[] titles = {"Fragment1", "Fragment2"};

    public MyPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        if (position == 0) {
            return MyFragment.newInstance();
        } else {
            return AnotherFragment.newInstance();
        }
    }

    @Override
    public int getCount() {
        return titles.length;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return titles[position];
    }
}

public void updateData(String data) {
    // 处理传递过来的数据
}
